Balance (BAL) Control (Bose Applications)
The BOSE models have the same feature functionality for all channels except the subwoofer output The subwoofer, which has the left and right audio summed together, will have the audio cut completely from the opposite channel at the last left and right balance steps ONLY (full right balance will cut left audio channel to subwoofer). Intermediate balance adjustments will have no effect on the subwoofer output level. The radio display is not affected by balance changes.
