NOTES FOR INSTALLATION
Amplifiers HC 1600 / HC 2000 are designed to be housed in 19” racks / flight-cases (height: 2 units).
If the installation is made inside a rack enclosure, we recommend you to use the attachment
fittings on the back of the amplifier, so the front panel does not have to support the entire unit
weight. Make sure there is sufficient ventilation for the amplifier to be cooled correctly. Do not
obstruct the rear part of the amplifier (in order to guarantee the necessary air intake).
CONNECTION TO THE MAINS
This unit must be connected to a mains supply that can deliver at least the maximum power
required. Do not use extension cables or adapters that could compromise the proper current
delivery.
COOLING
Cooling is handled by a circuit that automatically regulates the fan speed in relation to the
temperature rise (this reduces the fan noise to the minimum as well).
INPUT GAIN ADJUSTMENT
The input gain is normally set to 0 dB. It can be set to +4 dB by removing the jumper labelled JP1
present on both the channels.
