12 Installation
NOTE: In-line XLR connectors often have a termination
lug that connects directly to the chassis of the connector.
Do not link this lug to pin 1 at the amplifier's input as
it will defeat the amplifier's input grounding scheme.
This lug is often referred to as a "drain" and is used to
provide a termination to the chassis for shielding
purposes when a floating signal ground is required
between the source and destination, or when
disconnecting the signal ground is required to reduce
earth loop noise, or noise induced into signal grounds
from stray magnetic fields.
Output Wiring
When wiring to your speakers always use the largest
gauge wire your connector will accept. The longer the
speaker lead the greater the losses will be, resulting in
reduced power and less damping at the load. We
recommend using a heavy duty two core flex (four core
flex if bi-amping) 10 to 12 gauge (2mm
50/0.25 or equivalent) as a minimum.
Binding Post Outputs
When terminating to the 4 mm binding post (banana
jack) output connectors, banana plugs or bare wires
can be used. The red terminal is positive and the black
terminal is negative (ground).
If running in BRIDGE mode, only the red binding
posts are used. Channel A provides the positive
output to the load and channel B provides the
negative output to the load.

Figure 5. "Speakon" Connector Wiring Diagram
When using the NEUTRIK SPEAKON (NL4MP)
connector for speaker output, use only the mating
NEUTRIK NL4FC in-line connector. This connector is
designed so that both channels can be fed from a
single connector.
Two SPEAKON connectors are provided on the
amplifier. The "Channel A" SPEAKON actually
carries both Channel-A & Channel-B outputs (see
Figure 5: Speakon Connector Wiring Diagrams).
The "Channel-B" SPEAKON carries the Channel-B
output only.
This arrangement allows you the option of connecting
to the outputs separately or together. Connecting
through a single connector has the advantage of
minimising connections, preserving phasing and
simplified channel allocation, which is particularly
2

to 2.5mm
or
important when bi-amping or in bridge mode.
IMPORTANT
Do not overload your amplifier by connecting the
Channel-B output twice!
Channel-A is used as the "dominant" channel and
when sourcing a dual output from Channel-A the
following standard should be used:
Channel-A = Left or Low Frequencies.
Channel-B = Right or High Frequencies.
When in bridge mode:
Pin 1+ = Bridge Output Positive
Pin 2+ = Bridge Output Negative.
