Operating Your Amplifier: Rear Panel Sockets and Switches
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.
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
Error! Bookmark not defined. .
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.
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.
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.
WIRING CONVENTIONS
The speaker outputs are via Neutrik Speakon connectors: 2-pole (NL2FC) or 4-pole
(NL4FC) connectors can be used. Terminations (all connectors) are as follows:-
Pin +1 = +ve signal output
Pin -1 = -ve signal output
For ease of installing bi-amped or bridged speakers, output connector A also carries
output B and output connector C also carries output D. The terminations are as
follows:
Output connector A Pin +1 = +ve channel A Pin -1 = -ve channel
A
Pin +2 = +ve channel B Pin -2 = -ve channel
B
