If you have lost the jumpers, please contact either your dealer or
the factory for replacements. A single ended input without the XLR
jumper will result in diminished performance.
You may now connect the power supply to it’s control chassis
stages. Other than being line voltage specific the power supplies are
universal to the X
s
Preamps. Both right and left channel powerCON
connections must be properly made up before AC power is applied.
powerCON cable end connectors insert into their respective
chassis connectors and then lock with a 1/8 turn clockwise.
Insert the cable connector into the chassis receptacle; turn to
lock until they click and latch. Verify that they latch and lock
before proceeding.
Last cable to be attached is the mains cable. Please make connection
with the power supply IEC 320 socket first, house mains last.
Failure to follow this sequence can damage speakers and in some
instances result in increased likelihood of electrical shock. As with
all electrical devices the power cord (when used) is always the first to
be removed and the last to be connected, no exceptions.
At this point you should be ready to play music.
The powersupply chassis connects to the electrical mains by a
standard IEC 320 detachable power cord and to the control chassis
by two 1.5 m powerCON umbilicals. On the rear of the power
supply chassis is a single IEC 320 power inlet for connection to the
mains, below a single 3AG fuse holder rated for AC mains duty. To
the left and right side two locking powerCON connectors, which will
accept the supplied, interconnecting powerCON umbilicals.
Safety disconnect is provided only by the detachable AC power
cord. Under normal operation access to the AC power cord must
be maintained in the event of electrical failure. The AC power
cord should be removed from the mains and then the power supply
when the unit is left unused or during atmospheric electrical events
(lightening storms). Under normal circumstances and for best sonic
performance the unit is left powered up continuously.
The control chassis is a true dual mono design: Right and left
channels receive power independently via independent dedicated
powerCON umbilical cables. In all instances of power and signal
