• 2 stereo lines (unbalanced)
• 2-band independent tone control (Bass, Treble) for the microphone/line 3 and line 1&2 input connection.
• Auxiliary output for liaison with other amplifiers or external audio devices
• Local control by digital rotary knob (“encoder”)
• Remote control by infrared remote control
• Remote control by WPmVOL or WPmVOL-SR (0-10 VDC) wall panel
• RS-232 control port, compatible with EclerCOMM software (free) and control protocol CA-NET
• MUTE port to silence the entire unit by closing external contact

INSTALLATION

WARNING: Non-compliance with the instructions or neglecting warnings may cause malfunction or even damage the unit:

1. Avoid turning on the device without the speakers connected to its outputs and without having previously set the volume/gain controls to a minimum level.
2. Always use shielded cables to make connections between devices.
3. 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 CA120HZ is suitable for installation on a wall or under a surface (table, shelf, cupboard, etc.), thanks to the 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 environment 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 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 an internal bridge (see section 11. CONFIGURATION DIAGRAM).

• Line signals (LINE1, LINE2, LINE3): they have unbalanced minijack or double RCA type stereo connections. They are prepared for the 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 CAN NOT 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 the mix bus to be amplified and routed to the OUTPUT in mono format
• LINE2: only the LINE2 input is sent to the mix bus to be amplified and routed to the 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 format
• 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

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 uses a Euroblock connector.
The connection cable between the CA120HZ output and the speakers 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. The auxiliary output AUX OUT has a line level signal (0dBV) which is an unamplified replica of the signal delivered to the OUTPUT terminals.

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 (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 WPm 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 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 CA120HZ 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 CA120HZ if an external device works on it (example: an emergency and centralized 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:

• Baud rate: 9600 (fixed, without auto-negotiation)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None

WIRING RS-232 – DB9

RS-232 CA120HZ| DB9
Tx| Pin 2 (RxD)
Rx| Pin 3 (TxD)
Gnd| Pin 5 (Signal Gnd)

• 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.

OPERATION AND USAGE

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. 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 CA120HZ. 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 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.

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 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 accessing and operating in these 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 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.

AUTO STANDBY Function
The AUTO STANDBY function (idle or low consumption mode) means you can install the CA120HZ in inaccessible 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 9. DIAGRAM 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 CA120HZ 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 CA120HZ 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 mode 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: 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 intelligibility.
• Note: If the input signal is too high, the CLIP indicator lighting up very frequently over a short time interval (a few seconds), the amplifier may go into protection mode, being muted to return to normal operation in a short time
• 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 light-up during special adjustment modes bass frequencies (see section 7.2. Special active source selection mode and setting adjustments)
• TREBLE: This light-up during special adjustment modes, treble frequencies (see section 7.2. Special active source selection mode and setting adjustments)
• LINE1, LINE2, LINE3/MIC: These lights 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 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 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 rejects 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). When the TALKOVER function is on, the LINE3/MIC signal will attenuate the selected line (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 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

Lock mode
To switch the CA120HZ 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 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 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 CA120HZ 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
