G) Standby
The standby LED (white) illuminates when
current overloading is detected by the power
supply. At that moment the main power supply
voltage, that feeds the amplifying stage channels,
gets disconnected. The secondary voltage supply
will still be on, and will turn off only when the
mains power cord gets unplugged and/or the
amplifier is switched off (See Switch On/Off
section).
H) Cooling air outlet grilles
Fan cooling permits airflow through the most
vital parts of the amplifier. Since the airflow finds its
way out through these grilles, keep them as clean
and dust-free as possible to assure proper cooling.

REAR PANEL DESCRIPTION

A) Output connections
For connection of channel outputs to speakers,
both binding posts and Speakon NL4 connections
are provided.
For the binding posts, polarity is clearly
indicated by black (–) and red (+) output terminals.
For the Speakon situated on the right, pin
assignments are:
Channel A : +1 / -1.
Channel B : +2 / -2.
Bridge : +1 / +2.
For the Speakon situated on the left, pin
assignments are:
Channel B : +1 / -1.
Thus you may choose to connect both
channels using only one or the two Speakon
EN
connectors, depending on your needs.
B) Inputs
An XLR input is connected in parallel to an XLR
output.
Nominal input impedance is 20k ohm for
balanced use and 10k ohm for unbalanced use.
Polarity complies with AES14-1992 (ANSI
S4.48-1992) and therefore pin assignments are:
1 = GND (Ground).
2 = (+) non-inverted signal.
3 = (–) inverted signal.

C) Input mode
This switch allows the selection for the input
configuration mode: stereo, parallel or bridge.
Typically the amplifiers are used in stereo
mode, where the input to channel A feeds channel
A and the input to channel B feeds channel B.
Parallel mode allows feeding both channels
with the signal plugged into channel A. Channel
B's input is disconnected in this mode.
Bridge mode allows easy wiring of an amplifier
in mono mode. The input to channel A feeds both
channels with appropriate polarity. Refer to the
"Bridge Mode Operation".

D) Mains lead
The mains lead is terminated on a plug that will
change according to the amplifier's mains voltage
and area location. If you need to cut off the plug to
replace it for the type used in your region, cable
colour codes are brown (live), blue (neutral) and
yellow-green (earth).
E) Fan inlet grilles
Like for the front outlet grilles, keep clean and
dust-free to assure free air intake for proper
cooling.
