LINE INPUTS AND OUTPUTS
The inputs are made via 3-pin XLR connectors, which
are electronically balanced and should be connected via a
high grade twin core screened cable, as follows:
Pin 1: Screen (see note below)
Pin 2: Hot ()
Pin 3: Cold (signal -)
The amplifier is designed to operate with fully balanced equipment and ground loops or loss of
performance may be experienced if connected to unbalanced sources. If it is unavoidable however, the
following wiring should be used. The cable should still be twin core plus screen.
Pin 1: Screen - connected to the chassis of the unbalanced equipment - or left disconnected at the
unbalanced end.
Pin 2: Hot ()
Pin 3: Cold (ground 0V)
NOTE: This amplifier is wired to the latest industry recommendations. Pin 1 is connected directly to the
chassis/mains earth. If ground loops (mains hum) are encountered remove the screen connection from the
other end of the cable and leave it open circuit. If problems persist, consult your dealer/supplier.
DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS
INSIDE THE AMPLIFIER.
For bridged operation input should be made to channel A (or C) only and the channels set for bridged
mode for the appropriate pair of channels.
Outputs are also made via 3-pin XLR connectors
wired as follows:
Pin 1: Screen (see note above)
Pin 2: Hot ()
Pin 3: Cold (signal -)
Note that the rear panel outputs are electronically
balanced and so are not galvanically (electrically) isolated.
Front panel outputs are transformer balanced and so are
isolated.
SPEAKER OUTPUTS
The speaker outputs are via Neutrik Speakon connectors. 2 pole (NL2FC) or 4 pole (NL4FC) connectors
can be used.
Pin 1+: Hot
Pin 1-: Cold
Additionally, Channel 1 Speakon connector carries Channel 2 output on Pins +2 & -2 to allow easy bi-
amping or bridged operation using a single NL4 connector. Similarly, Channel 3's Speakon connector also
carries Channel 4 output.
