The KAV-1500 amplifier is shipped with shorting pins in the XLR inputs. These pins
should remain in the XLR inputs if the amplifier is operating in the single-ended mode.
When the shorting pin is insert,ed, pins 1 (lower left) and 3 (top) are shorted together.
Remove the shorting pins to connect the amplifier for balanced operation.
The XLR pin configuration is described below:
Pin 1 Ground
Pin 2 Non-inverting (0
°)
Pin 3 Inverting (180
°)
Krell recommends using balanced interconnect cables. Balanced interconnect cables
not only can minimize sonic loss but are also immune to induced noise, especially with
installations using long cables. Balanced connections have 6 dB more gain than single-
ended connections. When level matching is critical, keep this gain value in mind.
