INTRODUCTION

The eCA120HZ is a very small mono amplifier with high impedance output (70/100 V line) and a remote control function via its 0-10 VDC port, it’s an ideal choice for audio-visual applications: school rooms, meeting rooms, multimedia presentations, commercial premises, etc.
Main characteristics

• 1 x 120 W RMS @ 70/100V high impedance
• Universal external power supply
• AUTO STANDBY function: in the absence of an audio signal the unit automatically goes into STANDBY mode, minimising power consumption
• Lightweight, silent, high-performance amplifier (fan-free convection cooling)
• 1 unbalanced stereo line input (LINE IN / STACK), with dual RCA connector and 3-pin Euroblock connector
• Local volume control by knob
• Remote volume control by WPm series wall panel (0-10VDC)

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 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 eCA120HZ 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. 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 eCA120HZ input channel only supports stereo line signals (or two mono signals). It has an unbalanced stereo connection with dual RCA connector and 3-pin Euroblock connector (LINE IN / STACK). This input is designed to support -6dBV to 0dBV signals, given that the rotary volume control of the front panel provides an extra +6dB of gain at its maximum position. This audio input can receive signals from CD players, radio tuners, mixing consoles, media players, audio outputs of computers and tablets, etc. LINE IN and STACK connections are linked, so that when you use one of them as an audio signal input for your unit, you can use the other to send that signal to another unit or external equipment.

NOTE: Turntables CANNOT BE CONNECTED directly to this device because none of the inputs have an RIAA preamp.

Audio output connections
The amplified output (OUTPUT) uses a Euroblock connector with a common terminal (0V), a terminal for a 70V line and another terminal for a 100V line. Always use the common terminal and, depending on the type of speaker in the system, one of the two others, 70 or 100V, to feed the loudspeaker line. The connection cable that connects the eCA120HZ connectors and the speakers should be good quality, with a suitable cross section and as short as possible. The OUTPUT provides an amplified version of the mono-converted input signal. Remember that the total power used by the speakers connected to the eCA120HZ output should not exceed the maximum power it can provide.

Remote control port
The RJ-45 REMOTE connector allows to connect a WPmVOL-type wall control panel (or another model of the WPm series) to adjust the overall output volume. The connection is made with a standard CAT5 cable between the WPm wall panel and the REMOTE connector of the eCA120HZ. The jumper labeled “REMOTE” on the front panel has to be in the ON position to enable the remote volume control.

OPERATION AND USAGE

Start up
Start up the eCA120HZ by connecting the equipment to an external power source to which the DC 24V connector of the eCA120HZ 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.
Once turned on, the front volume control (VOLUME) and the controller connected to the REMOTE port (if any) may be used to set the output volume of the signal amplified by the unit.

AUTO STANDBY Function
The AUTO STANDBY function (idle or low consumption mode) means you can install the eCA120HZ 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 the AUTO STANDBY mode, the jumper labeled “AUTO STBY” on the front panel has to be in the ON position. When it is enabled and after 2 minutes or more without any audio signal at the audio input of the device (or a very weak signal, lower than the activation threshold), the eCA120HZ will automatically switch into standby mode, lighting up the amber ON/STBY LED located on the front panel of the device. When a valid audio signal is detected in any of the inputs, the eCA120HZ leaves standby mode and starts operating normally again and the ON/STBY LED goes green.
When enabling the AUTO STANDBY mode with the front panel jumper (ON position), one of the 2 following assumptions may occur:

• There is NO audio signal in the inputs. Result: the amplifier immediately goes into AUTO STANDBY mode
• There is an audio signal in the inputs. Result: the amplifier stays active

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

• 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).

Setup jumpers

• REMOTE: enables (ON) the remote volume control from a WPm-type wall panel (or another model of the WPm series) connected to the REMOTE port.
• AUTO STANDBY: Switch the AUTO STANDBY function on (ON) or off. When the function is on, the eCA120HZ will automatically go into STANDBY or low consumption mode in the absence of audio signals in its inputs.

CLEANING

The eCA120HZ 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.
