The Model 302 Stereo Power Amplifier offers unprecedented compatibility with associated audio
components. When connecting or disconnecting speaker or interconnect cables, the amplifier
should be placed in Standby mode (blue POWER INDICATOR LED on the front panel OFF).
If you are using balanced XLR interconnects from your preamplifier or source component, position the
INPUT SELECT switch (1) to BALANCED INPUT. If you are using unbalanced RCA interconnects, position
the INPUT SELECT switch to UNBALANCED INPUT.
Connect the corresponding interconnect cables to either the BALANCED INPUTS (2) or UNBALANCED
INPUTS (3) on each channel. Both RCA and XLR inputs cannot be used for the same channel
simultaneously. For example, an unbalanced output connection from a surround processor and a
balanced output connection from a CD player cannot both be connected to the same channel at
the same time.
A slight mechanical click may be heard when the balanced XLR interconnect cables are correctly
installed and locked. The unlocking tab (located on the input connector and labeled “PUSH”) must be
pressed to disconnect the XLR interconnect cable from the amplifier.
Unscrew the knob that secures the speaker output connectors on both the LEFT SPEAKER OUTPUT (4)
and the RIGHT SPEAKER OUTPUT (5) 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 on both the LEFT (4) and
RIGHT (5) CHANNEL. Secure the loudspeaker connections by tightening the knob securely with your
fingers.
The Model 302 will only accept spade terminations for loudspeaker cables. Banana plugs or bare wire
connections cannot be used and must be reterminated with spade connections.
The Model 302 has two pairs of binding posts per channel to facilitate bi-wiring. Both sets of binding
posts are active and connected in parallel with no difference in signal quality. If your loudspeakers are
capable of bi-wiring and you wish to do so, simply connect one pair of binding posts from each
channel to the high frequency terminals of your loudspeakers and one pair of each channel to the low
frequency terminals of your loudspeakers.
+ 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.
