Connect the left-channel + (positive or red) output post of the Proceed

AMP to the + (positive or red) input terminal of the appropriate loud-

speaker.

Connect the left-channel – (negative or black) output post of the AMP to

the – (negative or black) input terminal of the appropriate loudspeaker.

Repeat this procedure for the remaining channel(s).

5 BALANCED AUDIO INPUTS

Accepts right-channel and left-channel signals from preamplifiers with bal-

anced outputs via high quality XLR connectors.

The pin assignments of these XLR-type female input connectors are:

PUSH

Pin 1: Signal ground

Pin 2: Signal + (non-inverting)

Pin 3: Signal – (inverting)

Connector ground lug: chassis ground

These pin assignments are consistent with the standards adopted by the

Audio Engineering Society. Refer to the operating manual of your balanced-

output preamplifier to verify that the pin assignments of its output connec-

tors correspond to your Proceed AMP. If not, wire the cables so that the ap-

propriate output pin connects to the equivalent input pin.

If you are planning to use balanced connections between your preamplifier

and any particular channel of the AMP, select the balanced input by sliding

the input select switch (see Item 6, below) toward the XLR input. Then

connect the balanced outputs of your preamplifier to the corresponding

balanced inputs on the AMP.

6 INPUT SELECT SWITCH

This small switch is found between the balanced XLR input and the single-

ended RCA input on each channel of the AMP. Use it to select which of the

two inputs you plan to use.

The input select switch disables the unselected input in order to avoid any

pickup of stray noise from an open input. It also causes the effective

gain of that channel to be adjusted (either 23 dB balanced or 29 dB

single-ended, to compensate for the 6 dB difference in signal level in

these two connection standards). Should you use your AMP in a home

theater system, this adjustment allows you to use any combination of

balanced and single-ended connections without having to worry about

going outside the adjustment range of your Dolby™ Pro Logic™

decoder’s output calibration circuitry.
