Before attempting any system interconnection, please familiarize yourself with the front panel control of the Model 312 Stereo Power Amplifier.
(1)FRONT PANEL STANDBY/POWER BUTTON: Press this button to operate the amplifier. Press again to place the amplifier in Standby mode.
(2)FRONT PANEL STANDBY/POWER INDICATOR: This small, blue light will illuminate when the amplifier is operational. When the light is not illuminated, all amplifier inputs are muted and internal circuitry reverts to
NOTE: All ON/OFF power switching should be initiated ONLY with this button. The amplifier should not be disconnected from AC power without first placing the amplifier in Standby mode.
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) or the AC mains power plug should be removed from the amplifier.
(A)BALANCED INPUTS: If you are using balanced XLR interconnects from your preamplifier or source component, position the INPUT SELECT switches (B) to BALANCED INPUT.
(C)UNBALANCED INPUTS: If you are using unbalanced RCA intercon- nects, position the INPUT SELECT switches to UNBALANCED INPUT.
Connect the corresponding interconnect cables to either the BALANCED INPUTS (A) or UNBALANCED INPUTS (C) 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 inter- connect 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.
