With the addition of the optional Remote Level Control (HD-RLC), you can control the volume of one, two or all three channel pairs of the XD600/6 from the front of the vehicle. This is useful for subwoofer level control, rear channel level control, center-channel level control or even as a master volume control for the system.
The HD-RLC connects to the jack labeled “Remote Level Control” on the Connection Panel of the amplifier using a standard telephone cable (supplied with the HD-RLC). If desired, multiple XD (and HD) amplifiers can be controlled from a single HD-RLC controller using a simple phone line “splitter” and multiple phone cables.
When connected to the amplifier, the HD-RLC operates as follows. At full counter- clockwise rotation, the audio will mute completely. At full clockwise rotation the level will be the same as if the HD-RLC was not connected at all. In other words, it operates strictly as a level attenuator.
“Remote Level Mode” Switch: This switch allows you to assign the operation of the HD-RLC to one, two or all three pairs of channels. In the “All” position, the HD-RLC knob will affect all three channel pairs equally. In the “3-6” (middle) position, only the level of channels 3, 4, 5 and 6 will be affected by the HD-RLC knob (channels 1 & 2 will not).
In the “5&6” position, only the level of channels 5 and 6 will be affected by the HD-RLC knob (channels 1, 2, 3 and 4 will not).
