FRONT PANEL
POWER BUTTON The power button turns the amplifier on and off. The Sonance logo power button has three settings:
· SOLID WHITE means the amplifier is engaged. The amplifier has power, is turned ON and ready to operate.
· SLIGHTLY DIMMED means the amplifier is in sleep mode.
· BLINKING WHITE means the power supply is in thermal protection. In this situation, the channel LEDs also illuminate red, indicating that the power supply is in thermal protection mode.
NOTE: UPON INITIAL POWER UP, THERE WILL BE A 20-30 SECOND DELAY BEFORE SOUND IS HEARD DURING THE BOOT UP CYLE. THE INDICATOR LEDS WILL ILLUMINATE RED, THEN GREEN, THEN GO OUT. THIS IS NORMAL.
INPUT/OUTPUT LIGHTS When each channel is active:
· GREEN LED means a signal is present.
· BLINKING RED Input/Output LED indicates that the associated channel is being over-driven.
· SOLID RED Input/Output LED indicates that the amplifier is in protect mode. While in protect mode, the LEDs periodically light up green. This retests output to determine if the issue is resolved. Protect mode could be caused by a short in the wire, amplifier overheating, or other internal problem.
NOTE: WHEN ANY OF THE LEDS ARE RED, TURN THE AMPLIFIER OFF IMMEDIATELY. DETERMINE THE CAUSE OF THE PROBLEM BEFORE TURNING THE AMPLIFIER BACK ON.
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE FUSE WITH ONLY THE SAME TYPE AND RATING.
VOLUME LEVEL CONTROL Each channel on the amplifier has volume adjustments controlled in the SonARC software. The DSP 2-750 MKIII amplifier ships at the +0dB or moderate volume level.

no bare wires come in contact with the amplifier chassis. When bridging channels, use the two outside connections on each connector. The positive wire from the speaker should be on the left side connection and the negative connection should be on the right side.
IP CONTROL IP control is via the RJ-45 input. IP controls power On/Off, volume, muting, and input source selections for either global control or group control.
AC FUSE HOLDER To replace the fuse, unplug the power cord from the Power Cord Connector and use a screwdriver to remove the fuse holder.
POWER CORD The DSP 2-750 MKIII features a removable power cord. Plug the female end of the power cord into the Power Cord Connector on the amplifier rear panel and plug the male end into a grounded wall socket.
Do not plug the amplifier’s power cord into a convenience outlet on any other audio or video component. If you need to use an extension cord, use only a heavy duty (14 gauge or larger) extension cord to avoid starving the amplifier of the current necessary for full operation.
POWERING THE AMPLIFIER
The DSP 2-750 MKIII features a removable IEC power cord (see Figure 3). A 14-gauge EIA standard 120 volt grounded power cable is included with the amplifier. Each time the amplifier’s power cord is initially plugged in and the power switch is turned ON, all channel outputs are disconnected for approximately 9-12 seconds and all PROTECTION LEDs illuminate briefly while the amplifier boots up.
If the electrical service is subject to frequent sags, spikes or brownouts, a power conditioner designed for use with high fidelity equipment should be employed to protect the amplifier.
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE FUSE WITH ONLY THE SAME TYPE AND RATING.

VOLUME LEVEL CONTROL
The volume controls balance the desired sound levels per channel. Volume can be controlled three different ways with SonARC V2 (see Figure 9). 1. Output Volume 2. Turn On Volume 3. Maximum Volume Output volume ranges between -70 to 12. The volume level controls are set at +0dB by default.
Figure 9: SonARC Page In/Out Settings Output Volume IMPORTANT: USE CAUTION WHEN SETTING VOLUME LEVELS EITHER ON THE AMPLIFIER OR AN AUDIO SWITCHER AS NOT TO OVERDRIVE AND POSSIBLY DAMAGE SPEAKERS. VERIFY ALL SOURCES AS OUTPUT VOLTAGE VARIES FROM DEVICE TO DEVICE.
PROTECTION CIRCUITRY AND LEDS
The amplifiers have a multi-stage protection system to prevent damage to your amplifier and speakers.

AMPLIFIER CHANNEL PROTECTION If a channel encounters a short-circuit or extremely low impedance, the affected channel outputs automatically mute. The output of the affected channel remains muted until the fault is corrected. Only the affected channel outputs mute; all other channels continue to operate normally.
NOTE: IN BRIDGE MODE, THE PROTECTION CIRCUITRY SENSES A SHORT CIRCUIT ACROSS BOTH POSITIVE SPEAKER TERMINALS.
AMPLIFIER CHANNEL PROTECTION INDICATION Dual-color LEDS on the front panel of the DSP 8-130 MKIII illuminate to indicate the current operating status of each amplifier channel.
· BLINKING RED indicates that the channel is being over driven.
· SOLID RED indicates that the amp is in protect mode.
While in protect mode the LED lights periodically light green to retest the output to determine if the short has been removed. Protect mode could be caused by a short in the wire, overheating of the amplifier or possibly an internal problem with the amplifier.
If the amplifier senses a very low impedance or a short on its outputs, then it mutes its output and the protection LEDs turn red. The output remains muted until the fault is cleared. Check the rear panel block connector for shorted wire strands or reduce the number of speakers connected in parallel to the amplifier outputs. Sonance amplifiers are rated for a 4 ohm load or higher, such as two pair of 8 ohm speakers.
AMPLIFIER POWER SUPPLY PROTECTION The amplifier also has protection for the power supply. If the power supply heat sink temperature exceeds the design maximum, the protection circuit will activate, disconnecting all channel outputs. This is indicated by a blinking light on the front panel power switch.
IMPORTANT: OPERATING THE AMPLIFIER WITH ONE OR MORE CHANNELS IN PROTECT MODE FOR AN EXTENDED PERIOD OF TIME CAN DAMAGE THE AMPLIFIER.
IMPORTANT: WHENEVER THE PROTECTION CIRCUITS ARE TRIGGERED, UNPLUG THE AMPLIFIER’S POWER CORD FROM THE WALL OUTLET BEFORE TROUBLESHOOTING.
RACK EAR INSTALLATION
Accessory Rack Ears are included with the DSP 2-750 MKIII. Unscrew the four Phillips head screws (M4 x 0.7 pitch x 10mm long) found on each side of the left and right forward section of amplifier. Use these screws to connect the included rack ears to the amplifier (see Figure 10).

INPUT NAME User entered field with a maximum of 15 characters. Use these fields to describe the type of input connected.
INPUT SOURCE Pull down menu allows you to select which input you would like to assign to the channel.
OUTPUT SETTINGS/OUTPUT VOLUME
OUTPUT NAME The Output Name is a 15 character user entered field. Use this field to enter the name that describe the room or area the channel will be powering.

INFO User entered field with a maximum of 15 characters to name the amplifier. The basic setup is complete.
ADVANCED SETUP PAGE
This page in SonARC allows you to make advanced changes to the your amplifiers settings and configuration. To start click on the Advanced Setup button from your amplifier’s homepage.
GENERAL SETTINGS TAB
The Advanced Setup automatically starts out on the General Settings tab. This tab is used to set up the amplifier with a network connection, auto on method and other basic information.

OUTPUT VOLUME (BASIC SETUP) Play music with wide dynamics and bass that will not stress the system.
1. Start with the output volume for both 1L and 1R set at -30.
2. Slowly increase the volume up towards 12 and listen for any distortion or strain from the speakers. When you hear any distortion, reduce the volume one or two steps below this value.
3. Set this volume number for both channels. This provides maximum system performance and protects the speakers from being damaged by amplifier clipping and over-excursion of the woofers.
NOTE: LEFT AND RIGHT CHANNELS ARE LINKED. OUTPUT VOLUME IS LINKED TO TURN ON VOLUME IN BASIC SETUP.

IP SETUP
DHCP ON/OFF DHCP ON/OFF is the first option in IP setup. All Sonance DSP series amplifiers ship with DHCP (Dynamic Host Connection Protocol) ON. In most installations DHCP should be left ON except when you are using a control system for IP control. If you are controlling the DSP series amplifier using IP, then we suggest you turn DHCP OFF and use a static IP address.
IP ADDRESS The second setting in the IP Setup section is the IP address. When DHCP is ON, the current IP address will be displayed. To change the IP address set the DHCP to OFF. When DHCP is turned off the IP address that the router assigned to the amplifier continues to be applied. This IP address is a good place to start since it is not being used by another network device. If you wish to change the IP address, you should perform a scan of the network and only assign an unused IP address within the range of 9

your router. As a general rule, only change the last three digits of the IP address in the amplifier settings and only assign numbers between two and 254. This suggestion minimizes the chance of making the amplifier inaccessible. It is critical to type in the correct IP address. If the wrong IP address is entered, the amplifier could become inaccessible. Make changes to the IP settings only if you fully understand network setup.
RESETTING DHCP If the IP address is not known and the amp is locked out, use the DHCP reset method in Appendix A.
IP SUBNET MASK The third setting in the IP Setup section is the IP Subnet Mask. This is an advanced network setup function. Under most circumstances, this field should not need to be edited. Changes in this field should only be made by an experienced network administrator.
ID AMPLIFIER MODE When the power switch is turned ON, the power button on the front of the amplifier flashes to indicate which amplifier is being are programmed. Making the amplifier easy to identify in a multi-amp installation.
PASSWORD PROTECTION
The SonARC Interface can be protected with an additional password. The password feature is disabled as a factory default, but enabling and setting a password will increase the security of the settings on the amplifier.

Once a password has been set, the password screen will appear whenever a new web connection is made. The username will always be “sonance”. If an incorrect password is used three times in a row, a five minute cooldown period will be required. NOTE: RESETTING THE NETWORK SETTINGS OR FACTORY RESETTING THE AMPLIFIER WILL CLEAR AND DISABLE THE PASSWORD SETTING (SEE APPENDIX A).
BACKUP RESTORE
The green BACKUP and RESTORE buttons take all of the settings of the amplifier, including the DSP settings, and encapsulates them into one file. This allows the transfer of settings into another amplifier of the same model with the same firmware version. This is a proprietary file type (.bin file), agnostic to PC or Mac.

Enabling the password will open the Update Password page. The password requires a minimum of eight characters. If the password requirements are not met, or the password does not match in the confirmation box, SonARC will show an error message.

PRINT
The print button will output a complete list of all settings for the amplifier. It is always a good idea to keep a backup hard copy of the settings for each installation.
AUTO ON, POWER SAVING, & SLEEP MODE
Select the Auto On method you would like to use with the blue pull-down menu. During setup it is strongly recommended that you keep the Auto On method set to POWER BUTTON to prevent the amplifier from shutting off. You can return at anytime to the Auto On setting and select the final method of Auto On for your installation. When controlling the amplifier using IP and IR commands we suggest using the Power Button Auto On mode. See Appendix B. Power consumption in Sleep Mode is less than 0.5W.
AUDIO In the Audio Auto On mode, there are three sleep mode 10

options (off, 15 minutes, three hours). Each channel has an independent sleep mode setting. The sleep mode is triggered by an audio sensing circuit on each channel of the amplifier. The minimum input sensing level is 0.5mV.
AUDIO GREEN In the Audio Auto On mode the amplifier will sleep after 15 minutes without an audio signal present on any of the channels. When an audio signal is applied the amplifier will take approximately 9-12 seconds for the amplifier to reproduce audio after going through its power up sequence. In the audio Auto ON mode the sleep function is active, see sleep mode note below. This mode complies with EU energy saving standards when the network connection is inactive.
NOTE: WHEN AUDIO GREEN MODE IS ENABLED AND THE AMPLIFIER IS ASLEEP, THE NETWORK INTERFACE WILL BE DISABLED IF NO CONNECTION IS PRESENT. IN THIS CASE, IP COMMANDS CANNOT BE RECEIVED UNTIL THE AMPLIFIER WAKES UP FROM AN ANALOG AUDIO INPUT.
POWER BUTTON
When sleep mode is set to OFF the channel remains active at all times. Use the sleep mode OFF setting for audio signals (doorbell or paging) where audio must be reproduced immediately at any time.
VOLTAGE Amplifier will sleep immediately when the trigger voltage has been removed. When a 3-12V DC voltage or DC voltage is sent to the amplifier, it will take six to eight seconds for the amplifier to reproduce audio after going through its power up sequence.
VOLTAGE GREEN Amplifier will sleep immediately when the trigger voltage has been removed. When a 3-12V DC voltage or DC voltage is sent to the amplifier it will take six to eight seconds for the amplifier to reproduce audio after going through its power up sequence. In Voltage Green mode the Ethernet connection is not active when the amplifier is off! This mode complies with EU energy saving standards.

AFTER 15 MINUTES MODE When an audio signal has not been present on a channel for 15 minutes, the channel will go to sleep. AFTER THREE HOURS MODE When an audio signal has not been present on a channel for three hours, the channel will go to sleep. This mode works well for home theater installations.

OUTPUT GROUP The DSP 2-750 MKIII has two output group options, A and B. When using IP or IR to control the amplifier, commands are sent to an output group and not to a specific channel.
BRIDGE MODE When more power is required, two channels can be bridged. Follow the instructions on page 6, in the software, for connecting the wires then select Bridge ON.
OUTPUT SOURCE
SOURCE 1 Primary source you will direct to the speakers. Any of the inputs available on the amplifier can be selected. When channels are in the same output group, the inputs will all change in unison. Left inputs default to left outputs and right inputs to right outputs.
SOURCE 2 Secondary source that based on the mode Source 2 setting described below, will either override or mix with Source 1. This input could be used for a doorbell or paging for example.
MODE SOURCE 2 OFF When set to OFF, Source 2 has no effect on the operation of the channel.
MIX Input levels will be attenuated by 6dB, and signals will be summed.
MUTE When set to MUTE, Source 1 will be muted while Source 2 is active.

output group will automatically have identical levels. Turn on volume level is implemented when the amplifier is turned off with the power switch or goes into sleep mode.
MAXIMUM VOLUME IP or IR can be used to limit how loud the speakers will play in certain areas. Output Volume and Turn On Volume can never exceed the Maximum Volume. Maximum Volume is the highest volume level that the amplifier will output. The output group selected does not affect this setting.
GAIN OFFSET Allows channels in the same output group to have their levels adjusted independently by +/-6dB. This is an independent setting not affected by the output group.
MUTE Eliminates the output from the speakers. Channels placed in the same output group will change simultaneously.
EQ SETTING TAB
The EQ settings tab is used to assign your DSP EQ presets for each channel. EQ presets provide best possible audio quality for most Sonance speakers. EQ presets are available at: http://www.sonance.com/electronics/amplifiers/dsp.

OUTPUT FREQUENCY RESPONSE
This graph reflects the changes made below.
The EQ image shows EQ4 ON at 500Hz, the Q is set to three with a -6dB gain, creating a gradual dip in the lower midrange.
EQ9 shows ON at 3000Hz, the Q is set to ten with a -6dB gain, creating a sharp dip in the midrange.
EQ10 shows ON at 10000Hz, the Q is set to one with a +4dB gain, creating a very gradual slope in the high frequencies.

13

PARAMETRIC EQ
All Sonance DSP amplifier models feature a ten band parametric EQ. Adjustments made to the EQ will be displayed on the output frequency response graph. We strongly suggest not adjusting the EQ without proper measurement equipment.
EQ ON/OFF Turns each of the ten parametric EQ filters on and off.
EQ FREQUENCY HZ Enter the center frequency (20Hz – 20kHz) for the filter to be adjusted.
EQ-Q Determines the width of the adjustment range. The lower the number the wider the bandwidth. The higher the number the narrower the bandwidth.
EQ-GAIN +/- dB Level of each parametric adjustment can be set +/-12dB.
Careful adjustment of the EQ gain is necessary to prevent damage to the speakers. Always increase the level as little as possible. The first choice should always be to reduce the output to achieve the target frequency response.
DELAY
Delay is shown in milliseconds, feet and meters. You can make an entry in any of the three fields and the other fields will be calculated automatically. The minimum delay is .01 milliseconds, the maximum delay is 12 milliseconds. This function is useful when compensating for distance between satellites and subwoofers for instance.

GAIN Can be set in 1dB steps +/-12dB. When setting the gain use as little positive gain as possible to minimize the risk of damage to the loudspeakers.
CROSSOVER
LP XOVER/HP XOVER Turns the high and low pass crossovers on and off.
FREQUENCY Enter any frequency between 20Hz-20kHz.
FILTER TYPE
6dB, 12dB, 18dB and 24dB per octave Butterworth filters are available in the pull-down menu. The higher the number the faster the speakers output will be reduced below or above the crossover frequency. In a typical satellite subwoofer system the crossover frequency would be around 80-100Hz for both the high and low pass filters.

LIMITER
The limiter operates as a brick wall limit on the output of the amplifier. The limiter drop-down menu has options from zero to -6dB in 0.5dB steps. The maximum outputs for each of the models:

DSP 2-750 MKIII 8 ohm power

No Limiter 500 watts

-3dB 250 watts

-6dB 125 watts

TILT CONTROL
The tilt controls are very sophisticated bass and treble control. By selecting a start frequency and level you can ramp the bass and or treble up or down. The effect of the tilt control is visible in the output frequency response graph.

LOW TILT/HIGH TILT Turns the low and high tilt controls on and off.

FREQUENCY

Enter the start frequency of the tilt in Hz. To boost the

low frequencies you would typically set the low tilt to

100Hz. To boost the high frequencies you would set the

high tilt to around 5kHz.

OUT OF THE BOX TROUBLESHOOTING
NO POWER: Front panel Power LED does not illuminate when AC cord is plugged into an outlet and the amp is switched on.
· Cause: AC cable is improperly seated either at the back of the amp or at the AC outlet.
· Solution: Verify that both ends of the power cable are securely seated.
· Cause: There is no AC current at the outlet.
· Solution 1: Securely insert the AC cord into another known-working
· Solution 2: AC outlet has no power.
· Cause: A rear panel fuse is blown.
· Solution: Check the rear panel fuse and replace if blown. If the front panel power LED still does not illuminate, contact Sonance Technical Support for additional instructions.
NO AUDIO
Front panel Power LED illuminates but the amp will not pass audio.
· Cause: Current selected source is not transmitting an audio signal into the amp.
· Solution: Verify that the source is powered on, operating and not in a muted or paused state.
· Cause: Audio interconnect cables are not pushed-in securely at the source, at the preamp and/or at the amp’s input connectors.
· Solution: With the amp powered of, carefully reset each of the RCA connections at the source, at the preamp/zone controller.
· Cause: The line level interconnect cables are defective.
· Solution: Substitute another interconnect cable for the source to preamp.
· Cause: The speaker wires at either the output of the amp or at the speaker location are not securely connected.
· Solution: Reattach the speaker wires on the 4-terminal speaker block connectors.
· Cause: The amp’s power management option state is not being met (amp is set to voltage trigger and is not receiving a voltage).
· Solutions: Verify/reset the power management option to `Power Button’.

· Cause: The SonARC bridging option is engaged but the speakers are not wired properly for bridge mode.
· Solutions: Set the bridge mode to OFF. If audio output is still unavailable, contact Sonance Technical Support.
NO IP CONTROL
Made ethernet connection but IP control is not responding.
· Cause: Faulty ethernet cable.
· Solution: Check the rear-panel network LEDs on the input card are flashing to indicate network connectivity. If these LEDs are not active, replace the Ethernet cable. If the network LEDs are active but the DSP amp will not respond, perform the network reset as described below and retest.
· Cause: Faulty network switch.
· Solution: Connect the amp directly to the network router, bypassing the network switch.
· Cause: The amp’s IP address is improperly set.
· Solution: Scan the network, find the DSP amp’s IP address and enter it into your web browser. SonARC setup software should populate, showing the DHCP network address assigned to the amp by the router. In the Advanced Settings tab in SonARC, turn-off DHCP and set the fixed IP address of your choosing. Enter this IP address in your IP control module. Test the system with your control devices (touchscreens, iPhones with app, etc.). If the LEDs are still inactive and the other network devices are working properly, then the input card may need to be replaced, contact Sonance Technical Support. If the network LEDs are active but the DSP amp will not respond, perform the network reset as described below and retest.
NO IR CONTROL
The IR output from the control system is connected to the IR Control Input’ jack of the DSP amp with a monomini cable (not a stereo mini cable) but the amp will not respond to IR commands. · Cause: The DSP amp does not respond to IR commands using the mono-mini input jack. · Solution: Test the IR sending component by plugging a mini-emitter into its output and using the emitter to control a local AV component (such as a DVD player or AV receiver). Verify that theIR Status’ LED near the IR Control Jack illuminates when an IR command is sent, indicating that the amp is receiving the signal. If the local AV component can be controlled by the mini- emitter, then the problem may be caused by outdated firmware. Request the latest firmware from Sonance Technical Support.

17

CHANNEL OUT
One channel of the amp does not have output.
· Cause: Line-level interconnect cable from the source to the affected amp channel is loose, disconnected or faulty.
· Solution: Verify that the interconnect cables are properly seated at both the amp end inputs and source end outputs. Disconnect both interconnects on the amp end (1L and 1R input connections on the amp). Connect the functioning channel’s cable from the source to the non-functioning channel’s input jack on the amp (for example, if 1L is faulty, connect 1R’s cable to the 1L input jack and test). Test playback to see if the speaker connected to the non- functioning channel works. If the affected channel is now working, the problem could be with that channel at the source or with the interconnect cable for the non-functioning channel. Replace the affected channel’s interconnect cable and retest. Test source on another audio system to confirm channel outputs are functioning.
· Cause: Speaker wire leading out to the channel is loose, disconnected or faulty.
· Solution: Verify proper connection of the speaker wire at amp end and speaker end. If the channel is still inoperative, disconnect the speaker wire from the non-functioning channel at both the amp end and speaker end. Connect a new, test speaker wire from the affected amp channel output to the speaker or to a new, test speaker. If the affected channel is now working, the problem must be the speaker wire; replace with a new speaker wire. If the affected channel is still not working, the affected channel in the amp could be defective; contact Sonance Technical Support for next steps.
PROTECTION LEDS ARE ILLUMINATED
One or more red protection LEDs are on.
· Cause: The problem could be DC on the input of the amplifier, a short on the speaker wire going out to the zone, or a short at the speaker itself.
· Solution: Disconnect the speaker wire from that channel going out to the zone. If the protection LED goes out, connect your local test speaker, turn the amp back on and play music. If the test speaker produces sound, then the speaker wire leading out to the zone or at the zone speaker is shorted. If the test speaker does not produce sound and you’ve tried a different source on that pair of amp channels to rule-out a defective source, then the amp requires service; contact Sonance Technical Support for additional instructions.

FACTORY RESET
Perform a factory reset on the amplifier by inserting a small device (paper clip or #0 Phillips screw driver) into the RESET button hole on the back panel, and pressing the button for at least 10 seconds.
For additional support, contact Sonance Technical Support at www.techsupport@sonance.com.
