TThe Model 12 Mono Power Amplifier offers unprecedented
compatibility with associated audio components. When
Connecting or disconnecting speaker or interconnect cables, it is
necessary to place the amplifier in Standby mode (orange POWER
INDICATOR LED on the front panel OFF).
11 If you are using balanced XLR interconnects from your
preamplifier or source component, position the INPUT SELECT
switch to BALANCED INPUT. If you are using unbalanced RCA
interconnects, position the INPUT SELECT switch to UNBALANCED
INPUT.
22 Connect your interconnect cable to one input – either BALANCED
INPUT or UNBALANCED INPUT.
33 The PARALLEL BALANCED INPUT connector is for secondary
components requiring a parallel input signal. The output from
this connector is identical to the signal at the BALANCED INPUT.
This connector should be used for applications such as driving a
secondary amplifier for bi- or tri-amplification purposes or a
powered subwoofer. For parallel connection instructions, please
see the following two pages of this manual.
Note:Note: This connection should not be used with balanced XLR to
unbalanced RCA adaptors, as it will nullify the balanced audio
signal throughout the entire audio chain, including source
components.
44 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.
55 Unscrew the knob that secures the speaker output connector on
for the SPEAKER OUTPUT 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 (usually black) to the
negative (-) binding post. Secure the loudspeaker connection by
tightening the knob securely with your fingers.
+ Warning: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 can result in
damage to the amplifier and will void the warranty.
12V Remote12V Remote
11 AA 12V REMOTE ON/OFF mini-plug connector is provided on the
rear panel of the power supply for remotely switching the
amplifier between Operational and Standby modes. The
connections on this connector parallel the electrical contacts of
the FRONT PANEL STANDY/POWER button. When connected to
another component with the proper circuitry, the amplifier can
be turned ON and OFF remotely. Please contact your dealer for
further information about this feature.
