AB MAIN OUTPUT (DL1000 ONLY)
These are nominal +4dBu line level outputs on XLR
for connection to an external amplifiers. They are
differentially balanced using a 3 wire connection to
drive long cable runs without signal degradation or
interference pickup. Wire the cable using an inline 3-
pin female XLR plug. You can connect to an
unbalanced 2 wire input by linking pin 3 to pin 1 in
the plug as shown.
A and B outputs are affected by the 10-band graphic
equalisers. Use the MODE function to determine
which console mix is routed to these outputs:
A = L B = R Stereo PA
A = FB B = M Mono PA, single monitor
A = AUX B = FB External PA, two monitors
AB SPEAKER OUTPUT (DP1000 ONLY)
The power amplifier loudspeaker outputs are
available on industry standard locking Speakon
®
connectors. Use the MODE function to determine
which console mix is routed to these outputs. The
outputs can be configured as shown above.
Use Speakon
®
NL4FC cable plugs and wire the
speaker positive (+) cable to pin 1+ and speaker
negative (-) to pin 1-. Use heavy duty 2 core cable of
at least 10 Amp rating for the loudspeaker
connections. The cable does not have to be shielded.
Make sure that the connections are reliable and in
phase (speaker + to amp +, speaker - to amp -).
Ensure the plug is rotated and locked into position.
☺ Tip Check that the loudspeakers are wired
correctly in-phase by routing the same mono signal
to both outputs at the similar level and listening to
the sound when you stand centrally between them.
In-phase speakers have a solid centre image, out-of-
phase speakers produce a weak centre image with
strange ‘phasing’ effects.
Do not connect a load of less than 4 ohms
impedance. Failure to observe this may result in
damage to the amplifier. If you connect more
than one speaker to each output by linking them
make sure that the combined impedance is not
less than 4 ohms. Divide the impedances when
connecting in parallel, add the impedances when
connecting in series.
4 - 6 icon SERIES
To avoid damage to the amplifier do not
short the speaker connections together or link
them to ground.
