3. INSTALLATION

3.1. Placement and mounting

The amplifier is presented as a 2 unit high 19'' rack module. It is supplied with plastic washers in
order not to damage the unit when tightening the screws.
Always fix the amplifier to a 19" rack through the front ears using all corners and four screws.
For portable, mobile, or other applications where the rack assembly may be moved, we
recommend supporting the rear of the amplifier using support rails.
It is important that the amplifier, as a heat source, is not placed next to other equipment nor
exposed to high temperatures.

3.2. Mains connection

The amplifier operates on alternate currents, depending on the country 110-120, 220-240V
50/60Hz (see characteristics in the back of the unit). The power consumption at maximum performance
is 2500VA. It's important that your mains installation is adequately rated to these power demands.
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30 or
less). The environment must be dry and dustless. Do not expose the unit to rain or water splashes, and
do not place liquid containers or incandescent objects like candles on top of the unit. Do not obstruct the
ventilation grids with any kind of material.
In case there is some type of intervention and/or connection-disconnection of the amplifier, it is most
important to previously disconnect the mains power supply. There are no user or serviceable parts inside
the amplifier.
You should avoid that the supply cable twists with the shielded signal cables, as this could lead to
unwanted hum.
In order to protect the unit from an eventual electrical overload or momentary power peaks from
the internal circuits it carries a fuse. Should it ever blow up, unplug the unit from mains and replace it
with an identical one. If the new fuse blows again contact immediately with our Authorized Technical
Service.
CAUTION: THE FUSE IS INTERNAL AND SHOULD ONLY BE MANIPULATED BY QUALIFIED
SERVICE PERSONNEL. YOU MUST NEVER USE A HIGHER VALUE FUSE.
