6. INSTALLATION
Non-compliance with the instructions may cause malfunction and may even damage
the unit:
1. Avoid turning on the device without speakers connected to its outputs and
without having previously adjusted the volume / gain controls at 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 Placement, mounting, cooling
All eGPA amplifier models are presented in st andard 19” rack format and are 1 unit high.
It is important that the amplifier, as a heat source, is not placed next to other equipment
nor exposed to high temperatures.
CAUTION:
The built-in convection cooling requires at least one free rack unit
(empty space) both above and below each amplifier to ensure a correct air flow.
It is also advisable not to rack the power amplifiers under other devices, but on top of these,
that is to say as high as possible toward the top of the rack cabinet.
6.2. Mains connection
The eGPA amplifiers are powered by 100 to 250VAC, 50/60Hz.
The mains cables must not be near the shielded cables carrying the audio signal, as this
could cause humming.
In order to protect the power amplifier from eventual power consumption overloads, it is
protected by a set of fuses. Should a fuse blow, it must be replaced immediately by one
with identical rating. Should it blow again please contact our Technical Service
Department. NEVER REPLACE THE FUSE WITH ANOTHER ONE WITH A HIGHER
VALUE.
CAUTION:
Fuse substitutions have to be performed by a qualified technician.
