3. INSTALLATION
3.1. 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.
3.2. 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.
3.3. 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 10.
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 internal port (see section 10.
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
5
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 4.2. Special selection mode of active sources and adjusting settings for
details of the full procedure).
3.4. 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 7. DIAGRAM 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.
3.5. Remote control options
REMOTE port: the RJ-45 REMOTE type connector allows the connection of a
WPmVOL or WPmVOL-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 WPmVOL or WPmVOL-SR wall panel and the
REMOTE CA40 connector.
Because there is a CA40 WPm 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 WPmVOL-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.
6
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:
o Baud rate: 9600 (fixed, without auto negotiation)
o Data bits: 8
o Parity: None
o Stop bits: 1
o Flow control: None
RS-232 CA40 DB9
Tx Pin 2 (RxD)
Rx Pin 3 (TxD)
Gnd Pin 5 (Signal Gnd)
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.
4. OPERATION AND USAGE
4.1. 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.
7
4.2. 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 in 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:
8
Notes:
1. 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.
2. In tone control mode, when you turn the knob in either direction it flashes fast while the
gain of the affected tone increases. When either end of the scale is reached (-10 ó
+10dB) or when it goes through the centre point (0dB) it flashes more slowly.
4.3. 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 7. DIAGRAM 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.
4.4. LED indicators
SP: The 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/S
TBY: 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 4.2. Special active
source selection mode and setting adjustments)
9
BASS: This lights up during special adjustment modes bass frequencies (see
section 4.2. Special active source selection mode and setting adjustments)
TREBLE: This lights up during special adjustment modes, treble frequencies (see
section 4.2. 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 4.2. Special active source selection
mode and setting adjustments)
4.5. Micro switches on the rear panel
REMOTE: Turn on (ON) the remote control from the WPmVOL or WPmVOL-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.
TALKOVER: (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:
o BRIDGE y MONO OFF: Work in stereo mode L / R
o 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.
o BRIDGE OFF y MONO ON: Work in MONO mode, both channels
independent and each of them amplifying the L+R signal.

4.6. 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.
4.7. Restore default settings and update firmware
If you would like to restore the CA40 to factory settings, follow this procedure:
1. Switch off the equipment then press and hold the knob in.
2. Switch the unit back on without releasing the knob. The MUTE LED indicator will flash.
3. Wait a few seconds and then switch the CA40 off again.
4. 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.
5. 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.
