3. INSTALLATION

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.

3.1. 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.

3.2. 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.

3.3. 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.

3.4. 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.

3.5. 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.
