Krell Full Power Balanced X Series Power Amplifiers
Krell recommends using its proprietary Krell CAST system for
unparalleled sonic performance between the Full Power Balanced
amplifiers and other CAST-equipped components and the
KPS 25sc Krell Playback System.
Full Power Balanced amplifiers also offer balanced operation. The
circuitry and connections associated with balanced operation not
only can minimize sonic loss but also are immune to induced noise,
especially for installations using long cables.
A one piece RCA-to-XLR adapter is available from Krell Industries, to
allow single-ended operation using the balanced XLR inputs.
The following steps describe how to connect cables to the Full Power
Balanced Amplifiers.
1.
Turn all pwer sources and components off before connecting
inputs and outputs.
2.
Neatly arrange and organize wiring to and from the amplifier
and all components. Separate AC wires from audio cables to
prevent hum or other unwanted noise from being introduced
into the system.
3.
Connect the Krell CAST cables from your CAST-enabled pre-
amplifier/source component to the left and right Krell CAST
4-pin bayonet inputs (14) on the amplifier back panel. For bal-
anced operation, connect the interconnect cable from your pre-
amplifier to the left and right balanced XLR input (16) on the
amplifier back panel.
4.
Connect the loudspeaker cables to the Full Power Balanced
amplifier's loudspeaker binding posts (13), located on the ampli-
fier back panel. Loudspeaker binding posts for both stereo and
monaural amplifiers accept spade lugs only.
5.
Insert the end of the AC mains power cord (18) into the AC wall
receptacle.
6.
Proceed with Krell Trigger Connections, if desired, or turn to
Amplifier Operation, on page 16.
