3. INSTALLATION

3.1. Location and assembly

The CA120HZ is suitable for installation on a wall or under a surface (t able, 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 = 30Ω, or lower).
The environment should be as dry and dust f ree 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 / disconnect ion task be done, always disconnect the unit f rom 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 CA120HZ 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 (LINE1, LINE2, LINE3): 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: Turnt ables CANNOT BE CONNECTED directly to this device because none of the inputs
have an RIAA preamp.

The CA120HZ has the following operating modes according to the input sources selected as

active:

• LINE1: only the LINE1 input is sent to t he mix bus to be amplified and routed to t he OUTPUT in
mono format

• LINE2: only the LINE2 input is sent to t he mix bus to be amplified and routed to t he OUTPUT in
mono format

• LINE3/MIC: only the microphone (MIC) / line (LINE3) input is sent to the mix bus to be amplified
and routed to the OUTPUT in mono f or mat

• LINE1 + LINE3/MIC: the LINE1 and LINE3/MIC inputs are mixed, amplified and routed to the
OUTPUT in mono format. If the TALKOVER function is enabled, the LINE3/MIC input will
attenuate the LINE1 signal when the activation threshold is reached

• LINE2 + LINE3/MIC: the LINE2 and LINE3/MIC inputs are mixed, amplified and routed to the
OUTPUT in mono format. If the TALKOVER function is enabled, the LINE3/MIC input will
attenuate the LINE2 signal when the activation threshold is reached

6

Select one of the 5 work modes in special selection mode with the rotat ing 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 uses a Euroblock connector.
The connection cable between the CA120HZ output and the speak ers should be of good quality,

with a suitable cross section and as short as possible.

The output operates in mono mode only (L+R summed in case of active stereo input).
Additionally, the CA120HZ has an unamplified auxiliary output (AUX OUT) which makes it possible
to connect it to amplifiers or with other external devices. T he auxiliary output AUX OUT has a line level
signal (0dBV) which is an unamplified replica of the signal delivered to the OUTPUT terminals.

3.5. Remote control options

• REMOTE port: the RJ-45 REMOTE t ype 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 f ive active work source modes (LINE1, LINE2, LINE3/MIC, LINE1
+ LINE3/MIC, LINE2 + LINE3/MIC). The connection is made by a standard CAT5 cable
between the WPmVOL or WPmVOL-SR wall panel and the REMOTE CA120HZ connector.
Because there is a CA120HZ W Pm type control as well as other types of controls (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 W PmVOL-Sr wall panel connected to the REMOTE port, and then these
settings are adjusted using t he front control, the adjustment made with the frontal control will
prevail. In this case, when the wall panel position is adjusted again, the CA120HZ will change
to the values indicated, and so on and so forth.

• MUTE por t: The MUTE connect or makes it possible to connect a power free contact to totally
silence the CA120HZ 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
CA120HZ from a computer through the EclerCOMM software or CA-NET protocol from an
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 r at e: 9600 (fixed, without auto negotiation)
o Dat a bits : 8
o Par ity: None
o St op bits : 1
o Flow control: None

• Receiver IR: the built-in IR receiver gives general volume control of the CA120HZ 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 CA120HZ by connecting the equipment to an external power source to which the DC

24V connector of the CA120HZ has already been connected. T he LED indicator ON/STBY immediately

lights up on the front panel. W e 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 t hos e 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 CA120HZ. This controller has a maximum of 64 steps
between the unit's minimum and m aximum volume. When turned, it will adjust the volume while the LED
LEVEL light is flashing. W hen the controller is turned to the left or to the right, this flashes while the
output volume increases or decreases. The light stops f lashing when it reaches either end of the scale
and it is no longer possible to increase or decrease the volume of t he unit .

Quickly press the VOL/MUTE controller to activate/deactivate the mute function of the unit
(MUTE ON/OFF). The MUTE LED lights 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.

4.2. Special active source selection mode and sett ing adjustments

Use the knob on the front panel to access special modes f or 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 t he level of each source you can mix the signal fr om the microphone
or line (LINE3/MIC) and another line (LINE1 or LINE2), and the result of this mix will be controlled by the
general output volume of the unit together, in other words, respecting the relative levels set of each source.

The full procedure for acc essing and operating in t hese special modes and the options available in
each are set out in the following graph:

Notes:

1. If the device is in special mode for 10 seconds and the f ront knob is not touched, the equipment
automatically reverts to VOL/MUTE mode.

2. In tone control mode, when you turn the k nob 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

CA120HZ in inacces sible places and leave the device connected to the mains power supply permanently
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 CA120HZ automatically goes into
STANDBY mode, and the ON/STBY on the front panel of the device goes orange. W hen a valid audio
signal is detected in any of the inputs, the CA120HZ leaves standby mode and starts operating normally
again and the ON/STBY LED goes green.

When you enable AUTO STANDBY m ode 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 mode and you turn the VOL/MUTE knob to
adjust the volume or ac t ivate the MUTE function, the LED lights will come on for a shor t time then go out
again. Remember that t he 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 adjustm ent) 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 thres hold.

• 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 of f ) indicator s never stay on, but t hat t hey do so at m ost t o
the beat of the lowest sound frequencies. Otherwise the amplif ied signal will be distorted with
low quality and low intelligibility.

Note: If the input signal is too high, the CLIP indicator lighting up very frequently over a
short time interval (a few seconds), t he am plifier may go into protection mode, being m ut ed to
return to normal operation in a short tim e

• MUTE: This lights up when the MUTE function is active (silent mode)

• ON/STBY: the green light com es 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)

• BASS: This light up during special adjustment modes bass frequencies (see section 4.2.
Special active source selection mode and setting adjustm ent s)

• TREBLE: This light up during special adjustment modes, trebl e frequencies ( see section 4.2.
Special active source selection mode and setting adjustm ent s)

• LINE1, LINE2, LINE3/MIC: These lig hts up during special modes, selection of active sources
and adjustments (see section 4.2. Special active source selection mode and setting
adjustments)

10

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 func tion for the LINE3/MIC input. When
this function is active the microphone input is muted whilst there is no signal above the function
activation threshold, so the equipment rej ects background noise captured by the microphone
connected to it.

• TALKOVER: On or off according to the priority of the LINE3/MIC input over the line inputs
(LINE1 or LINE2). W hen the TALKOVER function is on, the LINE3/MIC signal will attenuate
the selected line (LINE 1 or 2) when the activation threshold set is r eac hed.

• AUTO STANDBY: Switch the AUTO STANDBY function on (O N) or off. W hen the func tion is
on, the CA120HZ will automatically go into STANDBY or low consumption mode in the
absence of audio signals in its inputs.

• LINE3/MIC: input selection between LINE and MIC3 (line level input from RCA connectors or
microphone level input from Euroblock connector)

• HPF: frequency selection (50 or 70 Hz) for the unit's high-pass filter

4.6. Lock mode

To switch the CA120HZ lock mode on or off hold in the VOL/MUTE control for 10 s econds 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 contr ol (it will flash t hr ee t im es 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 CA120HZ to factory settings, follow this procedure:

1. Unplug the equipment then press and hold the knob in.

2. Plug back the unit without releasing the knob. The MUTE LED indicator will flash.

3. Wait a few seconds and then switch the CA120HZ off again.

4. The next time you turn it on, the factory settings will be in the memory.

Note: for instruct ions 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.
