Front panel controls :
1. On/Off switch with Power LED
2. Gain Control
Input gain control allowing to attenuate the input signal that is sent to the various channels of the amplifier.
The dB control range is as follows:
Fully closed (the signal is at zero and not sent to the channels of the amplifier) or fully open (i.e. at rated
power: the signal is not attenuated at all and sent at the input power into the amplifier channels).
3. LED Display
Shows the master output level.
Rear connections
1. Line input
Jack sockets : These sockets are connected in parallel to the corresponding RCA connectors. Thus, you can
connect a second amplifier in series to the first unit to send the same signal into several amplifiers in order to
increase the audio power.
2. Speaker outputs
Binding posts or XLR/Jack (minimum load 4 Ohms)
Note
: To avoid damage to the speakers, only use speakers that have the same impedance and power rating as
the amplifier. Only use speaker cables and never signal cables as those used for microphones, music instruments
and audio equipment in general.

INSTALLATION
Electrical Connections
Prior to connecting the amplifier on a wall outlet, check following points
The mains outlet must be earthed and comply with the safety regulations. If in doubt, ask and electrician.
The mains voltage must correspond to the supply voltage indicated on the rear panel (+/-10%)
The On /Off switch must be in OFF position
The amplifier must be switched off prior to unplugging the mains lead.
Power On/Off
Always switch on the amplifier at last and switch it off at first in your audio installation. Set all controls to the
minimum in order to avoid unpleasant and even dangerous noise.
Installation and Operation
Your amplifier is a high power unit that must be installed at a well ventilated place far from heat, humidity, shocks
and dust to avoid malfunction, defaults, electrical shocks and the risk of fire. The cooling air enters via the front
panel and leaves via the rear panel. The good ventilation is therefore of paramount importance. If you install the
amplifier in an equipment rack or a flight case, make sure not to obstruct the air flow. Never install the amplifier in
a closed rack or flight case as a part of the heat is evacuated by the metal ground plate. It is recommended to
leave at least one free space below the amplifier.
