Strapping
A male 3-pin XL type connector is
provided
and
wired in
parallel
with
the

SPEAKON Output
Connector
The NEUTRI K
(NL4MP)
4way
SPEAKON connector
is
provided
asthe main speakeroutputtermination.
This emerging standard of loudspeakerlo
amplifier
connection allows access to both
channels ofthe
amplifier via the one connector
for bi-amp
applications. Channel-A is conside
red thedominar
channel and has both channelswired to the
Speakon
connector. See
lhe installation section of this
manual fordetailed
information on Speakonwiring.
9. Mains
Circuit Breaker
A
"push
to reset'thermal acting circuit
breaker is
supplied on
youramplifierproviding
overall
protedion
of
your
amplifier's
power
supply and the
interconnecting mains. The breakerwill isolatethe
"active" mains conductor in the event of a high
current inlernal fault
or in continued overload
condilions.
The breakerwillnot be ableto be reset immediately
affer tripping. A cool down
period
of around 30
seconds
is required before the breaker will reset
back into circuit. lfthe breaker"trips" immediately
aftera reset,lhen a fault may have developed within
theamplifier.
10. D.C. Rail Breakers
YourAll3OOZ a m
plifier
is frtted with
15 Ampthermal
acting circuit breakers as overload
protection
for
the output stage of
youramplifier.
These breakers are in series with the high cunent
supply railsto the amplifie/s
output stage and will
"trip"when:
1) An intemal fault exists;
2) There is a sustained overload;
3) There is a sustained
short
circuit;
4) There is a sustained load fault.
Front Panel lndication will result if one of the
conesponding Rail Breakers is
to
'trip".

8. Mains Lead
Youramplifierissupplied with a heavy duly mains
lead
(power
cord) appropriately rated forthe mains
supply voltage marked on the rear
panel
of
your
amplifier.
The
wires in lhe mains lead are coloured in
accordance with the following code:
