(1) LOUDSPEAKER OUTPUT: Unscrew the knob that secures the speaker output connector
and pull the securing block out far enough to allow access to the binding posts. Install the
positive (usually red) loudspeaker cable spade terminal to the positive (+) binding post and the
negative spade terminal to the negative (-) binding post. Secure the loudspeaker connections by
tightening the knob securely with your fingers. The Model 102 will only accept spade terminated
loudspeaker cables. Banana plugs or bare wire connections can be used but require an optional
clamp available from your JRDG Dealer.
(2) BALANCED INPUTS: XLR interconnects from your preamplifier or multichannel processor
should be connected to BALANCED INPUTS LEFT and RIGHT. A slight mechanical click may be
heard when the balanced XLR interconnect cables are correctly installed and locked into the rear
panel connector. The unlocking tab must be pressed to disconnect the XLR interconnect cable
from the amplifier. When using unbalanced RCA interconnects, you can convert the XLR inputs
to unbalanced operation by installing an XLR to RCA adapter, available from your JRDG dealer.
NOTE: Pin 2 of the XLR connector is signal positive with respect to speaker output positive. Also, JRDG recommends
balanced cables as the preferred method of interconnection. XLR to RCA adaptors are available from JRDG if RCA,
single-ended interconnects are used. Amplifier gain is not affected by choice of input type.
INSET: Master AC
Power Switch (102 S Only)
WARNING: Both positive and negative outputs
are electrically active with respect to chassis
and/or system ground potential. Therefore, this
amplifier cannot be used in certain loudspeaker
switching configurations, such as those used in retail
demonstrations. Failure to avoid these precautions
may short the outputs to ground and can result in
damage to the amplifier and will void the warranty.
Certain subwoofer speakers which derive signals from
amplifier outputs will require additional circuitry to
properly isolate the amplifier output. Please contact
JRDG before connecting these types of subwoofers.
