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 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.
6.1. 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.
6.2. 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.
