26. Additionally this output will be turned off when the “Power Save Mode” of the amplifier is active. The outputs can be assigned to any of the inputs as desired using the DSP PC-Tool software.

27. Attention: Solely use the connection cable which is included in delivery for the connection of additional amplifiers (see page 34, fig. 3)!

28. Optical Input
    Optical input in SPDIF format for connecting signal sources with a digital audio output. The sampling rate of this input must be between 12 and 96 kHz. The input signal is automatically adapted to the internal sample rate. In order to control the volume of this input, we recommend to use an optional remote control or the WIFI CONTROL.

29. Note: This amplifier can only handle stereo input signals and no MP3- or Dolby-coded digital audio stream!

30. Note: The manual activation of the Optical Input via an optional remote control is configured ex works.

31. SCP (Smart Control Port)

32. This multifunctional connector is designed for MATCH accessory products like a remote control which allows to adjust several features of the amplifier. Depending on the type of remote control, the functionality at first has to be defined in the “Device Configuration Menu” of the DSP PC-Tool software or on the remote control itself.

33. Attention: If the accessory product does not have a NanoFit connector solely use the NanoFit adaptor which is included in delivery for connection.

Switching between the two power modes

HighPower / MidPower mode

• The M 5.4DSP has two power modes – the “High-Power” mode for maximum perfomance and “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications.
• Note: The “MidPower” mode is always activated ex works.
• This mode reduces the output power of the front and rear channels to 35 Watts per channel. The result is a lower maximum current consumption of the M 5.4DSP and thus allows an easy Plug & Play connection to OE sound systems with an optionally available MATCH cable harnesses, e.g. PP-ISO (see page 38).
• Note: The “MidPower” mode is not a guarantee for a proper function in combination with the OEM harness. Depending on your car it may be necessary to connect the M 5.4DSP directly to a +12 V source.
• In order to use the M 5.4DSP in “HighPower” mode for maximum performance this has to be activated in the “Device Configuration Menu” of the DSP PC-Tool software.
• This setting may only be chosen if the power supply of the M 5.4DSP is directly connected to the car´s battery by using a separate cable with sufficient cable cross-section.
• Note: The M 5.4DSP can draw currents up to 40 A in “HighPower” mode. This may lead to an overload of the OEM harness (Fire hazard!).
• Note: The activation of the “HighPower” mode is set across all memory locations for all sound setups. The setting can be reset at any time via the DSP PC-Tool. After a complete reset of the amplifier via the Control pushbutton, the “High-Power” mode will also be reset.
• Note: The selected operating mode is also saved in the “afpx” configuration files. When loading an afpx file, this setting can be restored via the “Import ACO Features” button.

In the following the most important steps how to ac-tivate the “HighPower” mode are described:

1. Connect the amplifier to your computer using the USB cable that is included in delivery. If you have to bridge longer distances please use an active USB extension cable with integrated repeater and no passive extension. Optionally the connection can also be made by WIFI CONTROL via WiFi.
2. Turn on the amplifier and then start the software.
3. Go to the “Device Configuration Menu” (DCM) in the DSP PC-Tool software. In the “extended features” tab you can activate and deactivate the “HighPower” mode (see marking in the following image).
4. Confirm the following warning messages to finish the activation process.
5. Activation is finished.

The MATCH M 5.4DSP must be connected to the head unit (car radio) as follows:
Caution: Carrying out the following steps will re-quire special tools and technical knowledge. In order to avoid connection mistakes and / or dam-age, ask your dealer for assistance if you have any questions and follow all instructions in this manual (see page 17).

1. Connecting the highlevel loudspeaker inputs

2. Connecting the highlevel speaker inputs A -D: The highlevel loudspeaker inputs (see page 34, fig. 1, no. 1 – 4 and 11 – 14) can be connected directly to the loudspeaker out-puts of an OEM radio or aftermarket radio by using the enclosed MATCH connection cable. It is not mandatory to use all highlevel speaker inputs. It is sufficient if two of four highlevel loudspeaker inputs are connected. With the DSP PC-Tool software it is possible to route the input signals to the nine output channels individually.
   Make sure that the polarity is correct. If one or more connections have reversed polarity it may affect the performance of the amplifier. If this input is used the remote input (Remote In) does not need to be connected as the amplifier will automatically turn on once a loudspeaker signal is received.

3. Connecting the loudspeaker outputs A – D: The loudspeaker outputs (see page 34, fig. 1, no. 5 – 8 and 15 – 18) can be connected directly to the wires of the loudspeakers by using the enclosed MATCH connection cable. Never connect any of the loudspeaker cables to the chassis ground as this will damage your amplifier and your speakers. Ensure that the loudspeakers are correctly connected (phase), i.e. plus to plus and minus to minus. Exchanging plus and minus causes a total loss of bass reproduction. The plus pole is indicated on most speakers. The impedance per channel must not be lower than 4 Ohms, otherwise the amplifier protection will be activated.
   Attention: For connection, solely use only the enclosed System Connector connection cable or an appropriate cable harness from the MATCH accessories program!

4. Connecting a digital signal source

5. If you have a signal source with an optical digital output you can connect it to the amplifier using the appropriate input. In standard configuration the manual activation via an optional remote control is configured.

6. Alternatively you can activate the automatic turn-on feature in the DCM menu of the DSP PC-Tool software. The feature activates the digital input as soon as a digital audio signal is detected. The automatic turn-on function does not work when a digital input is used. Therefore it is mandatory to connect the remote input (Remote In). A simultaneous use of the digital input and the highlevel inputs is possible. Important: The signal of a digital audio source normally does not contain any information about the volume level. Keep in mind that this will lead to full level on the outputs of the M 5.4DSP and your connected amplifiers. This may cause severe damage to your speakers. We strongly recommend to use an optional remote control for adjusting the volume level of the digital signal input!

7. Information: The MATCH M 5.4DSP can only handle uncompressed digital stereo signals in PCM format with a sample rate between 12 kHz and 96 kHz and no Dolby-coded digital audio stream!

8. Adjustment of the input sensitivity Attention: It is mandatory to properly adapt the input sensitivity of the M 5.4DSP to the signal source in order to avoid damage to the amplifier.

9. The input sensitivity can be optimally adapted to the signal source using the DSP PC-Tool software.

10. Input sensitivity is factory-set to 11 Volts. This is definitely the best setting for most applications. Only if the head unit / car radio doesn´t deliver enough output level, the input sensitivity should be increased.

11. Follow the subsequent steps to perfectly adapt the amplifiers input sensitivity to your signal source:

12. Don‘t connect any amplifiers or loudspeakers to the outputs of the M 5.4DSP during this setup.

13. First turn on the amplifier and then start the software. The function can be found in the “Signal Management” tab of the DCM menu under the item “Main Input → Input Gain“.

14. Adjust the volume of your radio to approx. 90 % of the max. volume and playback an appropriate test tone, e.g. pink noise (0 dB).

15. If the clipping indicator in the DSP PC-Tool already lights up (see picture below), you have to reduce the input sensitivity using the scroll bar until the indicator turns off.

16. Increase the input sensitivity until the clipping indicator lights up. Now turn the control back until the indicator turns off again.

17. Connection to power supply

18. Make sure to disconnect the battery before installing the MATCH M 5.4DSP!

19. Connect the +12 V power cable (yellow) to the positive terminal of the battery. The positive wire from the battery to the amplifier power terminals needs to have an inline fuse at a distance of no more than 12 inches (30 cm) from the battery. The value of the fuse is calculated from the maximum total current input of the whole car audio system.

20. If your power wires are short (less than 1m / 40”) then a wire gauge of 4 mm² / AWG 12 will be sufficient. In all other cases we strongly recommend gauges of min. 6 mm² / AWG 10!The ground cable (black / same gauge as the + 12 V wire) should be connected to a common ground reference point (this is located where the negative terminal of the battery is grounded to the metal body of the vehicle), or to a prepared metal location on the vehicle chassis, i.e. an area which has been cleaned of all paint residues.

21. Connecting the remote input

22. The remote input (Remote In) has to be connected to the remote output of the signal source if the signal source which is connected to the highlevel inputs is not activating the “automatic turn-on” function or if the amplifier shall only be activated / deactivated by a remote signal applied to the remote input.

23. We do not recommend controlling the remote input via the ignition switch to avoid pop noise during turn on / off.

24. If one of the highlevel inputs of the System Connector is used this input does not need to be connected as long as the car radio has BTL output stages.

25. Configuration of the remote input

26. The M 5.4DSP will be turned on automatically if the highlevel inputs are used or if a remote signal is applied to the remote input terminal (Remote In). The Auto Remote switch (page 31, item 2) allows to deactivate the automatic turn-on feature of the highlevel inputs. The feature should be deactivated if there are e.g. disturbing noises while switching on / off the amplifier. Note: If the automatic turn-on function is deactivated it is mandatory to use the remote input terminal to power up the amplifier! The highlevel signal will be ignored in this case.

27. To deactivate the automatic turn-on feature you have to change the position of the Auto Remote switch to “Off”.

28. Configuration of the internal DSP

29. The general amplifier settings should be conducted with the DSP PC-Tool software before using the amplifier for the first time. Ignoring this advice may result in damaging the connected speakers / amplifiers. Especially if the M 5.4DSP will be used to drive fully active speaker systems, a wrong setup can destroy your tweeters right away.

30. Information on connecting the M 5.4DSP to a computer can be found on page 41.

31. Connecting a speaker to the subwoofer out-put
    The Subwoofer Output of the M 5.4DSP allows to connect a passive MATCH Plug & Play sub-woofer (like the MATCH PP 7E-D or PP 7S-D), a conventional subwoofer or speaker.
    Note: The Augmented Bass Processing can also be activated for this output in the standard signal processing concept of the DSP PC-Tool software.
    Use only the enclosed subwoofer cable for connecting a speaker (page 34, fig. 2)! The use of other cables may cause severe harm to the amplifier and or speaker. Connecting a passive MATCH Plug & Play sub-woofer:

32. Connect the 8-pole Molex connector of the subwoofer cable (A) to the connection cable of the MATCH Plug & Play subwoofer. (B).

33. Next, connect the 2-pole Molex connector of the subwoofer cable to the Subwoofer Output of the amplifier. Connecting a conventional passive subwoofer or speaker:

34. Disconnect the ASIA plug connection of the subwoofer cable (C).

35. Afterwards connect the loudspeaker cable of the speaker (D) to the ASIA round plugs of the subwoofer cable (E). Ensure that the loudspeaker systems are correctly connected (phase), i.e. plus to plus and minus to minus. Exchanging plus and minus can cause a loss of bass reproduction. The plus pole is indicated on most speakers. The impedance of the connected speaker must not be less than 2 Ohms, otherwise the amplifier protection will be activated.

36. Connect the 2-pole Molex connector of the subwoofer cable to the Subwoofer Output of the amplifier.

37. Connecting the line outputs F – I
    The pre-amplifier outputs has to be used for connecting additional amplifiers.
    Attention: Use only the enclosed Line Output-to-RCA / Cinch cable for connecting additional amplifiers (page 34, fig. 3). The Augmented Bass Processing can also be activated for the output channel Line Out 1 (F) in the standard signal processing concept of the DSP PC-Tool software.

38. Connecting the remote output
    This output (Remote Out) is used to supply remote signals to additional amplifier/s that are connected to the Line Out of the M 5.4DSP. Always use this remote output signal to turn on the amplifiers in order to avoid on / off switching noises.

Installation with a MATCH Plug & Play cable harness

To simplify installation to an OEM or aftermarket radio the M 5.4DSP can also be connected using optional Plug & Play cables from the MATCH accessory programm. The cables allow to supply the amplifier with both power and loudspeaker signals of the radio. No factory wires or plugs need to be cut by using this connection method.
ATTENTION: In “HighPower” mode the power supply of the M 5.4DSP must be connected directly to the car´s battery by using a separate cable with sufficient cable cross-section. Disre-garding this note may result in damage of the car audio system!

Connection to an OEM radio is detailed below using the PP-ISO cable harness as an example:

1. After removing the car radio from the dash using appropriate tools, disconnect the vehicle harness from the car radio. Next, connect the vehicle harness to the female connector of the PP-ISO cable, fig. 4 1 .

2. Depending on your car an additional car-specific adaptor may be required.

3. A list of all cars and the respective adaptors can be found on www.audiotec-fischer.com .

4. Connect the male connector of the PP-ISO cable (fig. 4 2 ) to the car radio.

5. Subsequently connect the 20-pole connector of the PP-ISO cable to the amplifier.

6. There are two alternatives to connect the M 5.4DSP to power described in section 4a and 4b.
   ATTENTION: In “HighPower” mode alternative 4b must be used.
   When connecting a subwoofer to the M 5.4DSP, we also recommend to use alternative 4b. Short interrupts in music reproduction at high listening levels are an indicator for significant voltage drops on the power supply due to insufficient vehicle cable harness dimension.

7. Power supply via vehicle cable harness:
   In this case the M 5.4DSP will be directly powered from the vehicle´s car radio harness. Carefully check its wire gauge and fuse rating first. If fuse rating is lower than 20 A then we strongly recommend option 4b.
   Note: Depending on the vehicle type the connections for switched (ACC+) positive terminal and constant positive terminal can be inter-changed. The M 5.4DSP must not be powered using the switched positive terminal as this might result in damage to the vehicle‘s electronic circuits. Verification of the right terminal must be made prior to activation of the unit at connections F (yellow) and G (blue) with a voltmeter. The constant positive wire is identified by a reading of 12 V even when the vehicle is turned off. After measuring connect cable H to the permanent positive terminal (see fig. 4). Note: The yellow wires are connected ex factory.
   If you are unable to identify the appropriate wires please ask your dealer for help.

8. Direct power supply via the battery:
   This wiring option has to be used if “ HighPower” mode is activated! It may also be necessary if a subwoofer is connected to the M 5.4DSP and the power supply of the amplifier cannot provided via the vehicle cable harness (max. 20 A).
   To do so disconnect joints (black, ground) and (yellow, +12 V) of the PP-ISO cable harness (see page 40, fig. 5 4 ). Next, the ground cable (black, fig. 5 3 ) should be connected to a common ground reference point (this is located where the negative terminal of the battery is grounded to the metal body of the vehicle) or to a prepared metal location on the vehicle chassis i.e. an area which has been cleaned of all paint residues by using a power wire with a wire gauge of min. 4 mm² / AWG 12. Always disconnect the car battery’s negative terminal before you execute the following steps. Connect the +12 V power cable (yellow, fig. 5 3 / min. 4 mm² / AWG 12) to the positive terminal of the battery. The positive wire from the battery to the M 5.4DSP harness connection needs to have a main fuse (min. 30 A) at a distance of no more than 12 inches (30 cm) from the battery. Insulate the now unused connections of th PP-ISO cable harness (see fig. 5 4 ) with tape or other appropriate material.
   You can now reconnect the car battery. If one of the cable extensions PP-EC 11, PP-EC 25 or PP-EC 40 will be used, the separate power supply has to be connected to the extension cable.

Note – Cars equipped with MOST bus:
In cars equipped with MOST bus structure it is mandatory to unplug the fiber- optic cable from the original car radio connector and insert it into the car radio connector of the MATCH cable harness which has a dedicated recess for this.

Installation with a MATCH Plug & Play cable harness

• 3 This side of the cable harness will be directly connected to the car´s battery. Therefore you have to separate intended cable joints of the harness.
  Yellow wire: +12 Volts wire for connecting the M 5.4DSP to the positive terminal of the car´s battery. Black wire: ground wire for connecting the M 5.4DSP to the negative terminal of the battery or directly to the car´s chassis.

• 4 After separating the cable joints the unused open wire ends (4) have to be properly insulated with
  tape or other appropriate material.

• I Power supply to the car´s battery. The +12 Volts wire and the ground wire have to be connected or soldered up to the respective joints of the PP-ISO cable harness. Afterwards it is important to insulate the two wires separately.

3. First turn on the amplifier and then start the software. The operating software will be updated automatically to the latest version if it is not up-to-date.
4. Now you are able to configure your M 5.4DSP with our intuitive DSP PC-Tool software. Nevertheless, interesting and useful hints can be found in our knowledge base at www.audiotec-fischer.com .

Caution: We highly recommend to set the volume of your car radio to minimum position during first start-up. Additionally, no device should be connected to the Line Out until general settings in the DSP PC-Tool software have been made. Especially if the M 5.4DSP will be used in fully active applications, a wrong setup can destroy your speakers right away.

Virtual Channel Processing (VCP)

• Operating concept of the VCP

  • In opposite to previous methods the Virtual Channel Processing (VCP) is a multi-stage signal processing concept that enables the perfect configuration of complex sound systems, opening up completely new possibilities for sound tuning.
  • The function extends the previous scope of the device by an additional layer of processed channels, which is located between the inputs and outputs. A total of eight additional processed virtual channels and nine processed output channels are available.
  • This virtual channel layer offers several advantages, especially in complex system configurations.

• The main advantages of this concept are:

  • Cross-channel group equalizers that affect several output channels simultaneously
  • Multi-way speaker configuration of DSP sound effects (SFX)
  • Additional features such as Rear Attenuation

• Cross-channel group equalizer

  • Example application: Active multi-way speaker configuration
  • If an input signal (e.g. front left) is first routed to a virtual channel (Front L Full) and this signal is then routed to an active multi-way system (e.g. front left – tweeter, midrange and woofer), the group equalizer of the virtual channel will influence all assigned output channels in their tonality. The advantage of this concept is that any amplitude and phase shift of the group equalizer is applied to all channels of the multi-way configuration simultaneously, thus avoiding any negative impact on the interaction of the individual speaker channels.

• Multi-way configuration of the DSP sound effects (SFX)

  • Example application : 2- or even 3-way center speaker
  • After activating “Virtual Channel Processing”, the DSP sound effects, such as RealCenter management or Augmented Bass Processing, are also available. These are no longer linked to the outputs but tied to specific “virtual channels”.
  • Front Processing: virtual channels Front L Full (A) and Front R Full (B)
  • Center Processing : virtual channel Center Full (E)
  • Augmented Bass Processing: virtual channels Subwoofer 1 (H) and Subwoofer 2 (I). The subwoofer volume is also tied to these channels.
    This makes it possible to route the DSP sound effects to any number of outputs, for example to realize 2- or even 3-way center speaker configurations. There are hardly any limits to flexibility here.

• Additional features
  In addition, the VCP enables the implementation of further new functions. One of these is, for example, the “Rear Attenuation”. With the help of a remote control, the volume of the virtual channels “Rear L Full” and “Rear R Full” can be controlled separately. So it is possible even without switching the sound setup, to adjust the volume of the rear speakers (or any other channel, which is routed through these channels).

Configuration of the Virtual Channel Processing (VCP)

To configure the VCP, you first have to enable “Virtual Channel Processing” in the DCM menu of the DSP PC-Tool software. Therefore, go to the “Virtual Channel Processing” tab in the DCM menu and click on the right box with the VCP graphic. Then the configuration will be carried out in two steps. Here’s an example of a 3-way configuration with a 2-way input signal.

1. Workflow step 1 – Input routing
   First, the input signals in the various input matrices (“Main to Virtual Routing”, “Digital to Virtual Routing”) need to be routed to the respective virtual channels. This is the same as in normal mode, means that the input signals on the left side are dragged and dropped onto the respective summation matrix. The difference to normal mode is that the names and signal properties of the virtual channels are defined here (Front L Full, Front R Full, Rear L Full, Rear R Full, Front Center Full etc.).

2. First, all input signals must be applied to the respective designated signal types of the virtual channels, means the input with the signal “front left” must be routed to the virtual channel “Front L Full” and so forth.

3. In the case of an adaptation of an OEM active multi-way system, all “front left” signals in this example have to be summed up on the virtual channel “Front L Full” (the input EQ remains effective in the inputs as usual).

4. Workflow step 2 – Output routing
   After all the input signals used in the respective signal routing matrix have been configured, the virtual channels must now be assigned to the physical output channels. Here, a virtual signal (e.g. Front L Full) can be assigned to multiple outputs, such as “front left” tweeter, midrange and woofer. The configuration of these speaker-specific output channels is done in the “Outputs” menu (called “Main” in normal mode) of the DSP PC-Tool. Here you can also configure the channel-specific equalizers, high- and lowpass filters, time alignment, output level and phase settings.

5. In order to assign the virtual channels to the respective output channels the individual virtual signals in the output routing matrix (“Virtual to Output Routing”) are dragged and dropped onto the output channels. At this point, the signals typically needn’t to be summed, means that each output of this matrix only receives one virtual signal. For example, the output “Front L High” is linked to the virtual signal “Front L Full”; the same is done for the Front L Low”.

6. At this point, even a virtual channel in which a DSP sound effect has been activated can be routed to multiple output channels. For example, the “Front Center Full” signal can be assigned to multiple output channels to create an active multi-way center speaker. The corresponding high- and lowpass filters are then configured in the output channels of the “Main” menu.

7. Workflow step 3 – Configuration of the virtual channels and notes on the application of the DSP sound effects (SFX)
   Now switch to the “Virtual” menu of the DSP PC-Tool. Here you get an overview of the signal flow of the individual channels and the activated sound effects. In addition, it is possible to influence the tonality of all subsequent output channels of a virtual channel at the same time, for example with the help of the equalizer, polarity and other functions.

Notes on the configuration of the DSP sound effects (SFX)

• The MATCH M 5.4DSP provides unique DSP sound effects such as Augmented Bass Processing, RealCenter, and more when “Virtual Channel Processing” is enabled. In order to enjoy the DSP sound effects, certain settings must be made in the hardware and software configuration.
• Note: The DSP sound effects are only available in the M 5.4DSP when “Virtual Channel Processing” is enabled. “VCP” can be activated in the DCM menu of the DSP PC-Tool software.

Notes for center processing with its features “RealCenter” and “ClarityXpander”
To be able to use the RealCenter and ClarityXpander function for a center speaker, the following steps must be carried out:

1. It is necessary to assign an input signal to the virtual channels “Front L Full” and “Front R Full” (see workflow step 1).
2. In the input routing you have to assign either a sum signal (front left + front right) or an existing center signal to the virtual channel “Front Center Full”.
3. Change to the “Virtual to Output Routing” matrix and route the “Virtual E – Front Center Full” channel to the desired output channels (as described in workflow step 2) to which the center processing shall be applied.
4. Now switch to the FX menu and activate the desired sound effect in the “Center Processing” tab by setting the appropriate check mark. Soundeffekt durch Setzen eines Hakens.

Notes for front processing with its StageXpander and ClarityXpander features
The StageXpander and Front ClarityXpander settings always affect the virtual channels “Front L Full” and “Front R Full”.

Hints for “Augmented Bass Processing” with its “Dynamic Bass Enhancement” and “SubXpander” function
For Augmented Bass Processing certain settings have to be made in order to use it.

1. An input signal has to be assigned to at least one of the virtual subwoofer channels (“Subwoofer 1” or “Subwoofer 2”) (see workflow step 1).
2. Change to the “Virtual to Output Routing” matrix and route the channel (s) “Virtual H – Subwoofer 1” and / or “Virtual I – Subwoofer 2” to the desired output channel or channels (as described in workflow step 2) to which the subwoofer signal and its Augmented Bass Processing shall be applied to.

Configuration of a subwoofer remote control

• First, the appropriate remote control must be activated in the “Extended Features” tab in the DCM menu of the DSP PC-Tool software and configured, depending on the model.
• If the VCP is not activated, the subwoofer remote control of the M 5.4DSP is permanently assigned to the output channels E and F of the Line Outputs. In this case it does not matter which output is named “Sub-woofer” in the IO routing matrix.
• In the main menu you can also see to which outputs the SubRC (subwoofer remote control) is tied:
• When VCP is activated, the subwoofer remote control is tied to the output channels that are supplied with one of the two virtual subwoofer signals (“Subwoofer 1” or “Subwoofer 2”) in the “Virtual to Output Routing” matrix. This can be any combination of output channels.
• In the following example these are the pre-amplifier outputs / Line Outputs F and G:
• Note: Please note that an input signal must be assigned to the two virtual subwoofer signals “Subwoofer 1” and / or “Subwoofer 2” in the other routing matrices.
• Afterwards, the subwoofer control is also displayed in the Main menu next to the name of the channel [SubRC]:

ACO platform features

• Beside the unique DSP sound effects the M 5.4DSP provides a bunch of new system features.
• In the DCM menu of the DSP PC-Tool software individual settings can be made for several of these system features.

Turn On & Off Delay
This function allows to determine the delay time with which the integrated DSP is switched on and off. The factory setting is 0.2 seconds. The delay time should only be modified if there are e.g. noises while switching on / off the amplifier.

URC Setup Switch Configuration

• The ACO provides ten internal memory locations for sound setups instead of the common two.
• By using an optional URC remote control or the Control pushbutton it is possible to toggle between two of the ten memory locations. These two memory lo-cations can be determined in the “URC Setup Switch Configuration”. The memory locations one and two are preassigned ex works. To switch between all internal memory locations, the optionally available remote controls DIRECTOR and CONDUCTOR or the HELIX WIFI CONTROL are / is recommended.

Remote Output Configuration
This function controls if the remote output (which switches on and off the connected amplifiers) will be temporarily deactivated during a sound setup switch. This function is activated (ON) ex works.

ADEP.3 Configuration

• If the M 5.4DSP is connected to an OEM radio via the highlevel inputs it may happen that the ADEP.3 circuit has to be adapted to the diagnostic mode of the radio if the latter is equipped with a so called “class SB” output stage.
• The ADEP.3 circuit should be adjusted if there are e.g. distortions in the upper volume range.
• The compatibility mode is disabled ex works.

Unique Features of the M 5.4DSP

• Class GD technology
  Audiotec Fischer´s proprietary Class GD concept takes the efficiency of conventional Class D amps to the next level. By varying the internal supply voltage in several steps depending on the amplifier’s input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time. So heat dissipation is almost negligible, thus allowing smallest heat sinks and most compact form factors.

• ACO – Advanced 32 Bit CoProcessor
  The MATCH M 5.4DSP amplifier incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation for all monitoring and communication tasks, both internally and externally. In opposite to the 8 Bit predecessor generation this MCU achieves way higher speeds with respect to setup switching and data communication with our DSP PC-Tool software. A further significant advantage is the integrated, native boot loader of the CoProcessor. It allows software upgrades of all components of the DSP in order to adjust the microcontroller-controlled ADEP.3 circuit for example at future modifications / changes in the diagnostic system of factory radios or if the device will be extended with additional interfaces. In addition, thanks to the new flash memory, the ACO offers 10 memory locations for sound setups instead of the common two.

• Start-Stop capability
  The switched power supply of the MATCH M 5.4DSP assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.

• Two power options
  The M 5.4DSP has two power modes – the “HighPower” mode for maximum performance and “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications.

• Smart highlevel input ADEP.3

  • Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular the latest generation of car radios is equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if a common amplifier will be hooked up – but not with the M 5.4DSP.
  • The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
