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

Polarity

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.

Input Impedance

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 and Sensitivity Settings

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.
