To choose between either the standard tape2 input function or the spe-
cial ssp input (which operates at unity gain), press and hold the
tape2/ssp button until its LED indicator changes color. Amber (matching
the other input LEDs) indicates normal tape2 functionality; green indi-
cates the special ssp mode of operation. (Again, see “Using Surround
Sound Processors” for more information.)
3 BALANCED AUDIO INPUTS
Accepts right-channel and left-channel signals from source equipment
with balanced outputs. Provisions are made for two balanced signals via
high quality XLR connectors, designated
cd1 and bal/aux.
The pin assignments of these XLR-type female input connectors are:
21
3
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 recently adopted
by the Audio Engineering Society. Refer to the operating manuals of your
balanced-output line-level sources to verify that the pin assignments of
their output connectors correspond to the PRE. If not, wire the cables so
that the appropriate output pin connects to the equivalent input pin.
Connect the right-channel and left-channel balanced outputs of your
source components to the corresponding balanced inputs on the PRE.
Note: If you do not have balanced sources and need more single-
ended inputs, it is possible to fabricate a cable to connect
line-level sources with single-ended output to these balanced
inputs:
1
2
3
Male RCA
(connect to source)
Male XLR
(connect to PAV)
22-gauge
buss wire
If you need them, your Proceed dealer can help you with these cables.
4 REC1 OUTPUT
These single-ended connections are used to provide a stereo signal to
the recording device which is connected to the tape1 input. Examples of
possible recording devices include a cassette deck, DAT, DCC, CD-R, or
Mini-Disc. Connect this output to the record input (sometimes also called
“line input” or simply “in”) of your recording device.
