Controlling Multiple Amplifiers with One Volume Controller

Several XPA 1002 and XPA 2001 series units can be daisy-chained so that one volume controller can simultaneously regulate the volume of all the amplifiers.

NOTES:

•As additional amplifiers are added to the daisy chain, the sensitivity of the volume potentiometer will change. The maximum volume level (fully clockwise) will not be affected. However, the effectiveness of the minimum volume level (fully counterclockwise) in reducing the volume to inaudible levels decreases as more amplifiers are added to the daisy chain.

•When more than two XPA Half-Rack units are attached to the chain, sound may be heard even if the levels have been set to their lowest. If complete muting is required, use a contact closure switch attached between the C (Vol/Mute) and the G (ground) pins of the first XPA Half-Rack unit in the chain.

To regulate multiple amplifiers with a single volume controller:

1.Attach all three pins of the volume controller to the corresponding pins on the first XPA Half-Rack unit only — Ground to G (ground), Vol/Mute to C (Vol/Mute), and 10 V to V (10 V).

2.Use jumper wires to connect the C (Vol/Mute) pins of the first amplifier and each successive amplifier.

3.Use jumper wires to connect the G (ground) pins of the first amplifier and each successive amplifier.
