Signal Connections and Remote

The 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).

1 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.

2Connect your interconnect cable to one input – either BALANCED INPUT or UNBALANCED INPUT.

3The 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: 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.

4A 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.

5Unscrew 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: 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 Remote

1A 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.
