Jeff Rowland Design Group 312 Constant 3v To 15v DC Signal 12VDC Typical tip Ground sleeve

(F)12V REMOTE TRIGGER: A 1/8” (3.5 mm) mini-plug connector is provided on the rear panel of the Model 312 for remotely switching the amplifier between Operational and Standby modes. When connected to another component with the proper circuitry, the amplifier standby function can be turned ON and OFF remotely in a custom installation, theater, or automated system setup.

NOTE: Please be aware that the remote feature simply places the amplifier in standby mode and does not disconnect the unit from power or AC mains.

NOTE: The amplifier must be placed in Standby mode with the front panel button before the 12V remote trigger function can be activated.

NOTE: Due to the exceptionally low power consumption rating of the Model 312, it is recommended that the unit not be disconnected from AC mains unless the amplifier is to be moved or reinstalled in another location. It is recommended that the amplifier be placed in Standby mode rather than disconnected from the AC mains power when the amplifier is not in use.

WARNING: If the unit is plugged into a voltage different from the range listed on the back panel, serious damage to internal circuitry will result and will void the warranty.

STEP 1: Verify that the VOLTS AC input identified on the rear panel near the AC input socket is the same as the AC mains voltage

in your area. If the voltage does not match, DO NOT CONNECT THE AMPLIFIER TO AC POWER and contact your dealer immediately.

STEP 2: Verify that the AC MAINS circuit breaker is closed (no white area visible on breaker).

STEP 3: Install the AC Power Cable between the amplifier and your AC mains outlet.

STEP 4: Connect the 12V Remote ON/OFF Mini-plug Connector if required.
