IDENTIFICATION OF CONTROLS AND CONNECTING AC POWER

Refer to Figure 2 to identify the controls of your subwoofer’s internal amplifier:

❶Auto Power: on/off switch for auto-sensing of audio signal

❷High Level Input and Output terminal strips

❸Low Level Input jacks: connect to preamplifier outputs

❹Volume Control: controls volume of subwoofer

❺Phase: reverse/normal switch to flip audio signal polarity

❻Frequency: controls upper corner roll-off point

❼AC Power: on/off switch for AC power to amplifier

Turn off your entire audio system prior to connecting your subwoofer. Make sure the subwoofer’s ON/OFF switch is in the “OFF” position.

If using an unswitched AC outlet on your receiver or amplifier is not possible, connect your subwoofer to an unswitched AC wall outlet. The BU-2 includes an “Auto-Sensing” circuit that automatically turns the subwoofer on when detecting music or voice signals. The absence of an audio signal for approximately six minutes will cause the auto-sensing circuit to shut down the system.
