INSTALLATION
WARNING: Non-compliance with the instructions or neglecting warnings may cause malfunction or even damage the unit:
- Avoid turning on the device without the speakers connected to its outputs and without having previously set the volume/gain controls to minimum level.
- Always use shielded cables to make connections between devices.
- In an amplifier, avoid placing the speaker output cables close to other signal cables (micro, line…). This may cause the system to oscillate, damaging the amplifier and speakers.
Location and assembly
- The CA40 is suitable for installation on a wall or under a surface (table, shelf, cupboard, etc.), thanks to its design and layout of its connectors, controls and LED indicator lights.
Mains connection
- The amplifier is powered by alternating current through its external power source: 100-240 VAC and 50-60 Hz.
- This apparatus must be earthed through its mains cable (earth resistance, Rg = 30 , or lower). The atmosphere should be as dry and dust free as possible. Do not expose the unit to rain or water splashes. Do not place liquid containers or incandescent objects like candles on top of the unit.
- Should any work or connection/disconnection task be done, always disconnect the unit from the mains supply. There are no elements that can be manipulated by the user inside the amplifier.
- To avoid buzzing, do not allow the power cable to intertwine with the shielded cables that transport the audio signal.
Audio input connections
The CA40 accepts two types of signals in its input channels:
- Microphone (MIC): has a balanced Euroblock or jack type connection, ready to accept a signal level between -20dBV y –50dBV, with adjustable sensitivity with the ADJ control
- NOTE: the microphone input has a phantom power supply to power condenser microphones, activated by internal bridge (see section 11. CONFIGURATION DIAGRAM).
- Line signals (LINE 1, LINE 2): they have unbalanced minijack or double RCA-type stereo connections. They are prepared for input of between -6dBV and 0dBV, with input sensitivity that can be adjusted by the internal port (see section 11. CONFIGURATION DIAGRAM). You can connect signals from CD players, radio tuners, mixing consoles, media players, the audio outputs of PCs and tablets, etc. to these connections.
- NOTE: Turntables CANNOT BE CONNECTED directly to this device because none of the inputs have an RIAA preamp.
- The CA40 has the following operating modes according to the input sources selected as active
- LINE 1: only LINE 1 input is sent to the mix bus to be amplified and delivered to the L and R OUT outputs
- LINE 2: only LINE 2 is sent to the mix bus to be amplified and delivered to the L and R OUT outputs
- MIC: only microphone (MIC) input is sent to the mix bus to be amplified and delivered to the OUT L and R outputs
- LINE 1 + MIC: the LINE 1 and MIC inputs are mixed, amplified, and delivered to the L and R OUT outputs. If the talkover function is active, the microphone signal attenuates to that of the line when it exceeds the activation threshold
- LINE 2 + MIC: the LINE 2 and MIC inputs are mixed, amplified, and delivered to the L and R OUT outputs. If the talkover function is active, the microphone signal attenuates to that of the line when it exceeds the activation threshold
- Select one of the 5 work modes in special selection mode with the rotating knob on the front (see section 7.2. Special selection mode of active sources and adjusting settings for details of the full procedure).
Audio output connections
- The amplified output (OUT L and R) have Euroblock connectors.
- The connection cable that connects the CA40 connectors and the speakers should be good quality, with a suitable cross section and as short as possible.
- The outputs can operate in stereo mode, mono (same signal L+R and both channels) or bridge (signal L+R amplified by both channels linked as one). These are selected using the micro switches STEREO-BRIDGE-MONO on the rear panel (see section 9. DIAGRAMS and LIST OF FUNCTIONS for more information).
- In bridge mode, the output signal connection is made through the positive terminals of each of the L and R connectors, the positive terminal corresponding to the L channel of bridge.
- Remember that the minimum work impedance for the amplifiers in mono or stereo mode is 4, and when working in bridge mode it is 8. For correct operation of the CA40, under no circumstances must you work with impedances lower than those specified above.
- Attention: in bridge mode only the terminals indicated on the serigraph on the equipment must be used for connecting the speakers.
- Additionally, the CA40 has an unamplified auxiliary output (AUX OUT) which makes it possible to connect it to amplifiers or with other external devices. The auxiliary output AUX OUT has a line level signal (0dBV) which is an unamplified replica of the signal delivered to the terminals OUTPUT L y R.
Remote control options
- REMOTE port : the RJ-45 REMOTE type connector allows the connection of a WpaVOL or WpaVOL-SR (control 0-10 VDC) wall control panel to adjust the general output volume and/or to select one of the five active work source modes (LINE 1, LINE 2, MIC, LINE 1 + MIC, LINE 2 + MIC). The connection is made by a standard CAT5 cable between the WpaVOL or WpaVOL-SR wall panel and the REMOTE CA40 connector.
- Because there is a CA40 Wpa type control as well as other types of control (front knob, infrared control and serial port control) the most recent adjustments by any of these methods will prevail. For example, if an active source is selected and/or a volume adjustment is made using the WpaVOL-Sr wall panel connected to the REMOTE port, and then these settings are adjusted using the front control, the adjustment made with the frontal control will prevail. In this case, when the wall panel position is adjusted again, the CA40 will change to the values indicated, and so on and so forth.
- MUTE port: The MUTE connector makes it possible to connect a power free contact to totally silence the CA40 if an external device works on it (example: a emergencies and centralised evacuation warning system).
- RS-232 port: the serial communication port RS-232 allows remote management of the CA40 from a computer or external control system supporting this protocol. See the CA-NET protocol manual for detailed information on the connection and syntax of the commands supported. The connection has the following specifications:
- Baud rate: 9600 (fixed, without auto negotiation)
- Data bits : 8
- Parity: None
- Stop bits: 1
- Flow control: None
WIRING RS-232 – DB9

- Receiver IR: the built-in IR receiver gives general volume control of the CA40 and its MUTE ON / OFF function from the REVO-IR remote control included with the unit.
OPERATION AND USAGE
Start up and default mode
- Start up the CA40 by connecting the equipment to an external power source to which the DC 24V connector of the CA40 has already been connected. The LED indicator ON/STBY immediately lights up on the front panel. We recommend you turn on all the devices in the following order: sound sources, mixer, equalisers, active filters and processors and, finally power amplifiers. Powering off should be done by following the exact reverse sequence. Following this order, the introduced noise due to turning on or switching off the devices will not affect those further on in the chain and will be inaudible.
- The system defaults to volume adjustment mode. In this mode, the VOL/MUTE knob on the front panel acts on the general output volume of the CA40. This controller has a maximum of 64 steps between the unit’s minimum and maximum volume. When turned, it will adjust the volume while the LED LEVEL light is flashing. When the controller is turned to the left or to the right, this flashes while the output volume increases or decreases. The light stops flashing when it reaches either end of the scale and it is no longer possible to increase or decrease the volume of the unit.
- Quickly press the VOL/MUTE controller to activate/deactivate the mute function of the unit (MUTE ON/OFF). The MUTE LED lits when the mute function is activated.
- If you adjust the volume using the infrared remote control, the LED LEVEL y MUTE visual indicators are exactly the same as those seen when adjusting these with the knobs on the front panel.
Special active source selection mode and setting adjustments
- Use the knob on the front panel to access special modes for selecting active sources and adjusting levels and equalization (bass and treble). You can access these modes by holding the knob for a certain time and then turning it. By adjusting the level of each source you can mix the signal from the microphone and another line, and the result of this mix will be controlled by the general output volume of the unit together, in other words, respecting the levels of each source.
- The full procedure for accessing and operating in these special modes and the options available in each are set out in the following graph:
CA40 adjustment with front knob browser
- SP: Short Press (press the VOUMUTE knob briefly, less than 0,5 s)
- LP: Long Press (press & hold the VOUMUTE knob for more than 2,5 s)
Notes:
- If the device is in special mode for 10 seconds and the front knob is not touched,the equipment automatically reverts to VOL/MUTE mode.
- In tone control mode, when you turn the knob in either direction it flashes fastwhile the gain of the affected tone increases. When either end of the scale isreached (-10 ó +10dB) or when it goes through the centre point (0dB) it flashesmore slowly.
AUTO STANDBY Function
-
The AUTO STANDBY function (idle or low consumption mode) means you can install the CA40 in inaccessible places and leave the device connected to the mains power supply indefinitely because when no signal is detected, it automatically goes into standby mode, saving energy.
-
To enable AUTO STANDBY use the micro switch with the same name on the rear panel of the unit (see section 9. DIAGRAMS and LIST OF FUNCTIONS). When activated, if there is no audio signal in any of the inputs (or the signal is very weak, below the activation threshold), the CA40 automatically goes into STANDBY mode, and the ON/STBY on the front panel of the device goes orange. When a valid audio signal is detected in any of the inputs, the CA40 leaves standby mode and starts operating normally again and the ON/STBY LED goes green.
-
When you enable AUTO STANDBY mode with the micro switch (position ON) one of two things happens:
a) There is NO audio signal in the inputs. Result: the amplifier immediately goes into AUTO STANDBY mode -
b) There is an audio signal in the inputs. Result: the amplifier stays active
-
When the amplifier goes into AUTO STANDBY mode, all the LED indicators go out with the exception of ON/STBY. If the amplifier is in STANDBY node and you turn the VOL/MUTE knob to adjust the volume or activate the MUTE function, the LED lights will come on for a short time then go out again. Remember that the first acting on the VOL/MUTE knob, this will only reset the LED indicators, and will not change any of the settings.
-
When the unit is a special mode (source selection or setting adjustment) the LED indicators will not go out even if the amplifier is in AUTO STANDBY mode.
LED indicators
- SP: T he signal presence or SP LED indicator shows that there is a signal in the amplifier input. This lights up when the input level reaches the established detection threshold.
- CLIP : The saturation or CLlP LED indicator comes on when the signal delivered to the speakers is close to the amplifier’s clipping or saturation level. Input signals should be set to ensure the CLIP (saturation or cut off) indicators never stay on, but that they do so at most to the beat of the lowest sound frequencies. Otherwise the amplified signal will be distorted with low quality and low integibility.
- MUTE: This lights up when the MUTE function is active (silent mode)
- ON/STBY: the green light comes on when the equipment is in normal operating mode and it goes orange when it is in standby or low consumption mode (STANDBY).
- LEVEL: This flashes when you adjust the general level of the device. It also lights up during special adjustment modes, input levels (see section 7.2. Special active source selection mode and setting adjustments)
- BASS: This lights up during special adjustment modes bass frequencies (see section 7.2. Special active source selection mode and setting adjustments)
- TREBLE : This lights up during special adjustment modes, treble frequencies (see section 7.2. Special active source selection mode and setting adjustments)
- LIN 1, LIN 2, MIC: These light up during special modes, selection of active sources and adjustments (see section 7.2. Special active source selection mode and setting adjustments)
Micro switches on the rear panel
- REMOTE: Turn on (ON) the remote control from the WpaVOL or WpaVOL-SR wall panel connected to the REMOTE port.
- NOISE GATE: Turn on (ON) or turn off the noise gate function for the microphone input. When this function is active the microphone input is muted whilst there is no signal above the function activation threshold, so the equipment rejects background noise captured by the microphone connected to it.
- TALK OVER: (ON) or off according to the priority of the microphone over the line inputs. When the talkover function is on, the microphone signal will attenuate to the line selected (LINE 1 or 2) when the activation threshold set is reached.
- AUTO STANDBY : Switch the AUTO STANDBY function on (ON) or off. When the function is on, the CA40 will automatically go into STANDBY or low consumption mode in the absence of audio signals in its inputs.
- BRIDGE / MONO (y STEREO): Select the work mode of the amplified outputs of the unit:
- BRIDGE y MONO OFF: Work in stereo mode L / R
- BRIDGE ON (and MONO in ON or OFF, indistinctly): Work in bridge mode, amplifying the L+R signal through both channels together as a single amplifier with joint power.
- BRIDGE OFF y MONO ON: Work in MONO mode, both channels independent and each of them amplifying the L+R signal.
Lock mode
To switch the CA40 lock mode on or off hold in the VOL/MUTE control for 10
seconds from the VOL/MUTE mode. The LED SETTING indicators will flash 3 times
to indicate that lock mode is now on. When in lock mode the device cannot be
managed using the VOL/MUTE control (it will flash three times to show that it
is in that mode when you turn the knob). This will protect the equipment from
unwanted handling until it is restored to normal operation after holding the
VOL/MUTE control in for a further 10 seconds (the LED SETTING indicators will
flash twice to show that the lock mode is off).
Note: once lock mode is activated it will stay activated even when the
equipment is turned off and on again. It will stay in lock mode until the
VOL/MUTE control is held in for 10 seconds again.
Restore default settings and update firmware
If you would like to restore the CA40 to factory settings, follow this procedure:
- Switch off the equipment then press and hold the knob in.
- Switch the unit back on without releasing the knob. The MUTE LED indicator will flash.
- Wait a few seconds and then switch the CA40 off again.
- The next time you turn it on, the factory settings will be in the memory.
Note: for instructions on how to update the unit’s firmware, see the product web page at www.ecler.com, where you will find the update software utility and instructions on how to proceed.
CLEANING
- The CA40 must not be cleaned with solvents or abrasive substances which may damage the prints. Clean using a cloth moistened in water and a neutral liquid detergent, then dry with a clean cloth. Under no circumstances allow water to enter any of the orifices in the equipment.

CA-NET RS-232 Remote Control Protocol
- The built-in RS-232 port in the rear panel of the CA and DAM series devices allows for external device communication via a serial connection. This kind of connection uses a syntax that is very similar to the one used in the Ecler TP-NET protocol: it lets a client device get from and/or set the values of several parameters of a CA / DAM device (for instance, the CA40 digital amplifier, like volumes, mutes, equalization tones, etc.
- The RS-232 serial communication must fulfill the following specifications:
- Baud rate: 9600 (fixed, no auto-negotiation)
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
- It’s not allowed to have more than one simultaneous access from several clients to the same CA / DAM device using the RS-232 connection.
- The protocol is simple and direct, syntax-friendly, making it easy to read, write and modify the generated code. It is based on messages with no begin delimiter: each message is self-delimited by the RS-232 packet size, which is defined with a maximum of 80 ASCII characters, and always including the character LF (0x0A) at the end of each message. All the messages must be written in CAPITAL LETTERS.
- To let some control systems (like EXTRON®, CRESTRON®, AMX®, RTI®, VITY®, MEDIALON®, etc.) process the messages more easily, the CA / DAM device adds the character LF (0x0A) at the end of each message it sends. This way the client of the CA / DAM device can buffer the received messages to process them, when required. The CA / DAM device can also handle several messages received in a single RS-232 packet by using the LF delimiter.
- The available messages are built with one or more fields separated with blank spaces ( = blank space):
- The first field (TYPE) defines the message type and then, the required parameters for it (each kind of message requires a given number of parameters). The field TYPE can have these values:
- GET
- SET
- DATA
- ERROR
- At the end of this document, you’ll find a table including all the available messages and their parameters for each model of CA-NET compatible device.
- The GET & SET messages can be sent from the client (control system) to the CA / DAM device. The DATA & ERROR messages can just be sent from the CA / DAM device to the client.
- The SET messages coming from a client device don’t have an automatic acknowledgement with a DATA message sent from the CA / DAM device after it has processed the SET command. The client must update the values itself, sending the needed GET message to ask for a parameter’s value when it requires confirmation from the device.
- On the other hand, when a local control in the CA / DAM unit occurs (for instance, using the front panel controls or an infrared remote control), the CA / DAM device will automatically send the associated DATA command via its RS-232 interface, to keep synchronisation with the client device.
- NOTES for CA40:
- A couple of special parameters for the GET and SET commands would require a detailed explanation:
- AUTOLOAD_PRESET1: its value (ON/OFF) defines whether preset number 1 must be recalled or not each time the CA device is powered ON, defining this way the default working mode at startup
- PANEL_LOCKED: its value (ON/OFF) defines whether the front panel controls (the rotary encoder in the case of the CA40) is enabled (PANEL_LOCKED=OFF) or disabled (PANEL_LOCKED=ON) for local management of the device. (see the CA40 user manual for further details)
- The numerical values are always integer numbers without comma or dot symbols
- are text strings (without blank spaces) that identify an audio input of a CA device:
- For the CA40, there are 5 possible Input Names:
- LINE1
- LINE2
- MICRO
- LINE1_AND_MICRO
- LINE2_AND_MICRO
- < Preset Number> is a numerical value that identifies one available Preset stored in the device’s memory. It can be within the [1..5] range.
- < Volume Level> are numerical values in the [0…64] range that define values in a scale equivalent to [-inf…Maximum_Volume] in 1.25 dB steps.
- < Tone Level> are numerical values in the [-10…10] range that define values in a scale equivalent to [-10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10] dB. If the numerical value is not in this list, the unit will reply with an error message.
- < Increment Value> are numerical values in the [0…64] range that define a value in a scale equivalent to [Increment Value]x(1.25) dB, used to increase or decrease the current absolute value of a level.
- < Threshold Level> the allowed numerical values in this field are just 3 [20, 25, 30]. It defines a value in a scale equivalent to [20, 25, 30] dB below the nominal level value for a given audio input. If the numerical value is not in this list, the unit will reply with an error message.
- < Depth Level> the allowed numerical values in this field are just 4 [20, 30, 60, 80]. It defines a value in a scale equivalent to [20, 30, 60, 80] dB. If the numerical value is not in this list, the unit will reply with an error message.
- < Attack Time Value> the allowed numerical values in this field are just 4 [50, 100, 200, 300]. It defines a value in a scale equivalent to [50, 100, 200, 300] milliseconds. If the numerical value is not in this list, the unit will reply with an error message.
- < Release Time Value> the allowed numerical values in this field are just 5 [300, 500, 1000, 2000, 3000]. It defines a value in a scale equivalent to [300, 500, 1000, 2000, 3000] milliseconds. If the numerical value is not in this list, the unit will reply with an error message.
- < Remote Select Value> are text strings (without blank spaces) that identify the function of the analogue (0 – 10 VDC) remote control selector connected to a physical “REMOTE” port in the device.
- In the case of the CA40, there are just two possible string values for this parameter:
- INPUTS
- PRESETS
- In the CA40, a single REMOTE port admits the connection of a WpaVOL-SR unit, which has a volume control knob and a 5-position rotary switch, or selector. The selector can be used in any of these two modes:
- INPUTS: to select the active audio source(s) (LINE1, LINE2, MICRO, LINE1_AND_MICRO or LINE2_AND_MICRO).
- PRESETS: to recall any of the 5 presets in the memory of the unit, which store the full configuration of the unit, including volumes, EQ, etc.
- The factory default working mode of the selector is INPUTS, and it can just be modified to PRESETS by means of an RS-232 connection.
- < Zone> are text strings (without blank spaces) that identify a zone where the command will operate.
- ZA (output labeled as ZA or L)
- ZB (output labeled as ZB or R)
- < Micro Name> are text strings (without blank spaces) that identify the MIC inputs in the unit.
- MICRO1
- MICRO2
- < Output Mode> are text strings (without blank spaces) that identify the amplifier’s output working mode.
In the CA40 there are just three possible values for this parameter:
-
* STEREO- MONO
- BRIDGE
- < Zone Label> is a text string that contains the customized name for a zone. The maximum length for this string is 17 characters, being ignored those exceeding this limit. Blank characters are not allowed. A valid example: MAIN_HALL
- < Display Mode> are text strings (without blank spaces) that identify the LCD display working mode.
- ON
