2, C~nnect the interconnect cables from your preamplifier, to the input of the Full
Power Balanced amplifier.
The Full Power Balanced amplifiers are equipped with balanced and single-
ended inputs. The balanced inputs use three pin XLR connectors and the
single-ended inputs use RCA connectors. We recommend the use of balanced
interconnects,.sonically and electrically, because of their immur~ty to induced
noise and minimal sonic loss resulting from long cable lengths.
CAUTION: Use only one set of inputs to the amplifier at a time. The Full Power
Balanced amplifiers are shipped with shorting pins in the XLR inputs, These
pins should remain in the XLR inputs if the Full Power Balanced amplifier is
operating in the single-ended mode. When the shorting pin is inserted, pins 1
and 3 are shorted together. The shorting pins must be removed to connect the
Full Power Balanced amplifiers for balanced operation.
The pin assignment for the XLR is:
pin 1 = shield (ground)
pin 2 = non_-inverting input (hot)
pin 3 = inverting in put
.3~ Insert the AC power cord into the receptacle located on the back of the Full
Power Balanced amplifier. Insert the other end in'to the AC wall receptacle.
The amplifier is now ready for operation as described in the Amplifier
Operation section below. Should you have any questions regarding system
set-up, contact your dealer or KRELL Industries.
¯ Linking Multiple Amplifiers - Remote In / Out connections
The Remote In/Out function is used to synchronize remote control operation in
systems that include multiple amplifiers. When the In/Out ports are utilized, the
connected amplifier's remote capabilities will be linked and controlled from one
amplifier.
Make sure all amplifiers are off, including the power breakers located on the
rear panel, before proceeding. This insures-all amplifiers are synchronized
when the communication cable is connected.
Select the amplifier that will be the control amplifier, Only this amplifier will
receive remote commands and should be in plain view for proper remote
control operation. All additional amplifiers are considered slaves and will
only respond to remote commands received via the In/Out communication
