Subwoofer bypass control A bypass control feature is included in the subwoofer circuits so that the effect of the subwoofer on the whole monitor system can be determined. With the bypass switch on, the high pass filters for the main monitors are overridden and the system behaves as if the subwoofer was not connected. The bypass function has no effect on the LFE input. Two different bypass remote controllers are available as optional equipment: 1092-400 switch that can be connected to a 1/4" jack connector on the amplifier panel and 7000-416 that connects to the "REMOTE" RJ11 connector.
