Operating Your Amplifier: Rear Panel Sockets and Switches

SERIAL NO.
1: Channel A output Speakon socket: Output is wired pins 1+: hot, 1-: cold.
Similarly channel B's output Speakon socket uses two poles wired as above.
2: Bridge/Stereo output Speakon socket: Output of both channels are available on this centre
socket. It is wired pins 1+: Ch. A hot, 1-: Ch. A cold, 2+: Ch. B hot, 2-: Ch. B cold. For details of
how to connect a speaker in bridge mode, see page 13.
3: Link switch: Press this switch to link the input of the channel A to both channels. Once
linked, only channel A's attenuator and meter will function.
4: Link XLR Socket: This socket is wired in parallel with its respective input socket to allow
the input signal to be linked out to further amplifiers. It is a passive connection so it will
function even when the amplifier is switched off.
5: 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.
6: 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. Please refer to the
power specifications on page 20 for more information on actual power reduction levels.
7: 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.
