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 eCA120 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 eCA120 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 has 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 ( OUT L and R ) have Euroblock connectors.
The connection cable that connects the eCA120 connectors and the speakers should be good
quality, with a suitable cross section and as short as possible.
The L and R outputs respectively deliver an amplified version of the L and R inputs of the unit.
Remember that the minimum load impedance for each output channel is 4

. For correct operation
of the eCA120, under no circumstances must you work with impedance lower than specified above.
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 eCA120.
The jumper labeled "REMOTE" on the front panel has to be in the ON position to enable the remote
volume control.
