1)
Power switch
Controls the supply of AC power to the amplifier.
2)
Power "ON" indicators / Bridge indicators
This double-color LED will light-up red whenever the amplifier is switched on. When the mode
switch (E) is set to bridged or parallel mode the color of this LED will change to yellow.
3)
Signal indicators
This green LED is lit-up whenever signal is present at the amplifiers input terminals. These
LEDs will light up at a signal level of signal level of -35dB.
4)
Clip indicators
This red LED will occasionally flash when the channel is just on the threshold of clipping. If this
LED is lit-up continuously, the level must be reduced to prevent severely distorted waveforms
from reaching the speakers.
5)
DC / Temp indicators
This red LED lights up whenever the channel’s output relay is in open position. For the output
relay to be open and the speakers disconnected any of the following conditions might apply:
The unit is powering-up and is in turn-on delay mode, there is a DC voltage present on the hot
output terminal or the channel is overheated
.
6)
Level adjuster
These controls are used to adjust input levels of the two channels.
7)
Removable dust filters
These filters avoids dust to get in the amplifier. The air filters should be cleaned periodically by
washing them in soapy water and rinsing them with clean water. This must be done at least
once a year, in dusty environments more regular.

A)
Screw terminal inputs
These terminals can be used to connect the input signal without connectors or soldering. Two
type signals can be connected to these terminals: Balanced (symmetrical) or unbalanced
(assymmetrical).
Balanced connection, must be done as follows: the positive (hot) signal must be connected to
the “+” terminal and the negative (cold) signal must be connected to the “-“ terminal. The
singal ground must be connected to the “GND” terminal.
Unbalanced connection, must be done as follows: the positive (hot) signal must be connected
to the “+” terminal. The signal ground must be connected to the “GND” terminal and to the “-“
terminal.
B)
XLR inputs
3-pole connectors to connect the input signal. These input can be used to connect balanced
(symmetrical) or unbalanced (assymmetrical) input signals.
Balanced signals must be connected as follows: The signal ground must be connected to pin
1, the positive (hot) signal must be connected to pin 2 and the negative (cold) signal must be
connected to pin 3.
Unbalanced signals must be connected is following way: The signal ground must be
connected to pin 1 and pin 3, the positive (hot) signal must be connected to pin 2.
C) XLR signal link outputs
3-pole connectors to link the input signal through to the other channel or to another amplifier.
Connections are the same as the input XLR connectors (B) for balanced signals.
