BALANCED INPUTS (CONTINUED)
again, the circuit will then engage. For use with balanced preamplifiers other than Classé, the
wiring of the 3-pin
XLR
connectors must be matched to that of the CLASSÉ
P-303
which is wired as
follows:
PIN 1: SHIELD (Should be connected only at the preamplifier end of the cable)
PIN 2: POSITIVE (NON-INVERTED) SIGNAL, “HOT”
PIN 3: NEGATIVE (INVERTED) SIGNAL
All Classé preamplifiers and amplifiers are configured as above. Some preamplifiers from other
manufacturers have PIN-3 set as the positive or “HOT” side. If this is true of your preamplifier, and
you wish to maintain absolute phase throughout your system, the interconnects must have the wire
which is connected to PIN-3 at the preamplifier output end switched to PIN-2 at the amplifier input
end and the wire which is connected to PIN-2 at the preamplifier output switched to PIN-3 at the
amplifier input end.
Having confirmed the correct connections, plug the
XLR
connectors of the balanced
interconnects into the locking
XLR
connectors on the rear panel of the
P-303.
Push the connectors in
until the locking mechanism clicks. (To remove the connectors, press the tab above the connector
while pulling gently on the connector body.)
