Product highlights:
The AF-RLC remote level control is compatible with the A600.1D amplifier. The RLC is connected to the amplifier using an attached RJ-15 phone cord. When attached, the RLC will allow the user to vary the level of the subwoofer amplifier between the level setting on the control panel and infinite attenuation.
One RLC can control more than one A600.1D amplifier and through a unique feature called RLC-Sync, the level of all of the connected amplifiers will be synchronized (within about 1dB) with the amplifier that has the lowest control panel level setting.
