of performance may be experienced if connected to unbalanced sources. If it is unavoidable, 

however, the following wiring convention should be used. 

 

Pin 1 

Screen - connect to chassis of the unbalanced equipment, 

or left disconnected at the unbalanced end 

Pin 2 

signal hot 

Pin 3 

Signal cold 

 

 

In accordance with international standards, T series amplifiers are supplied with Pin 2 hot (+), 

so a positive (+V) input gives a positive (+V) output from the positive (+) output terminals. 

 

Each amplifier channel has an input impedance of 10kΩ, seen between pins 2 & 3 of the XLR. 

When used with the LMS-D6 Loudspeaker Management System, distribution amplifiers are 
not required when a large number of T-25 or T-45 amplifier inputs are driven in parallel. 

 

Gain settings are changed internally by simple jumper links. Two rows of pins marked - GAIN 
A and GAIN B - are situated on the input PCB (PCB701). A jumper link sets the gain and the 

settings are as follows: 

 

 

 

Link 1 & 2 

Gives 32dB gain 

Link 3 & 4 

Gives 26dB gain 

Link 2 & 3 

Gives approx 37.5dB gain 

 

NOTE: Factory setting is normally link 1 & 2 = 32dB gain.
