AQ-10 Operating Instructions

Operating Your Amplifier: Rear Panel Sockets and Switches
1: Channel A output SpeakON
TM
socket: Normal output is on pins 1+ hot, 1- cold. Channel
B’s output is also wired to this socket to enable a single NL4 to provide both channels and to
facilitate easier wiring in bridged mode. Channel B is wired pins 2+ hot, 2- cold.
Similarly channel C’s output SpeakON
TM
socket carries Channel D’s output. Check the table
on the rear panel for details.
2: Link switch: Press this switch to link the input of the channel to its immediate left.
Multiple channels may be linked using these switches so, for example, to link all outputs to
input A, press all three switches IN and use input A only. The front panel attenuators will still
operate independently when channels are linked.
3: PRC switches: Each channel of the amplifier may be power limited independently using
these pairs of switches in three stages, offering 2, 4 and 6dB of Power Reduction Control.
The settings for these switches are on the rear panel for quick reference.
4: Input XLR sockets: Connect signal inputs to these sockets, wired pin 2 hot, 3 cold, 1
ground. For sensitivity and impedance of these inputs, please see the specifications on page
18.
5: Bridged (mono) switch (A+B): Press this switch to run this pair of amplifier channels in
bridged mode. To run C+D bridged, press the switch on the far left of the panel, beside
channel D’s input XLR.
6: Fan outlet: The variable speed fans suck air in through the front vents and out through
the back of the amplifier. Please see maintenance on page 17 for recommendations on how
to clean this and the front foam sections.
