DESCRIPTION OF CONTROLS

REAR PANEL

13) 

Normal/Bridge

: this  switch  must  be  engaged  when  using  a  bridged  amp  (32db 

gain)

14) 

Sub Input:

When this switch is released, the subwoofer derives its input from the 

sum  of  inputs  A  and  B;  when  it  is  engaged; it  receives  the  signal  from  an  external 
source (such as a mixer's auxiliary send).

NB

For proper operation of the protection circuitry, the gain of the amplifiers must 

be 26dB. Most amplifiers provide this gain as standard.

Warning: Excessive gain may result in speaker damage.

In particular, bridged amps exhibit a gain 6db higher than standard.

When using bridged amps it is necessary to use one of the following process:

Use the button normal/bridge situated on the rear panel

Modify the amp's gain structure, 

Use a 6 db input attenuator,

Turn the amp's potentiometer down 6 dB

APG, TG29, TG32, attenuators & TGxx (custom made), for 29dB, 32dB or other value 
are available on order. 

All inputs and outputs are electronically balanced: the connectors are 3 pin XLR'S

The  mains  receptacle  is  an  EEC  type  with  the  center  prong  connected  to  ground.  For 
obvious safety reasons, it should always be connected.

The processors can be operated continuously; thus they do not have a mains switch.

The processor uses a hum loop eliminator. If any hum or buzz occurs, it is not caused by a 
ground loop

F) When replacing mains fuse, type & value must be identical as indicated bellow:

220-240Vac

0,1 A Temp.

100-126Vac

0,2 A Temp.
