4. Connect the loudspeaker cables to the amplifier channel output binding posts

located on the back panel, (8) on the KAV–2250 or (9) on the KAV–3250.

The binding post terminals accept spade lugs, bare wire, or pins. Use the red
terminal for the positive connection and the black terminal for the negative
connection.

IMPORTANT
Tighten loudspeaker binding posts by hand only.


5. Plug the end of the AC power cord into the IEC power connector.

The amplifier is now ready for operation. See

Amplifier Operation, on page 13. You

can also reconfigure the amplifier for Multi Amp Throughput or bridged operation. See
Reconfiguration Options for the KAV–2250 and the KAV–3250, on page 15.

Amplifier Operation

ON/OFF AND OPERATION

When powering up your system, turn amplifiers on last. When powering down your
system, turn amplifiers off first. The procedures for amplifier operation follow.

1. Plug the AC power cord into the AC power wall receptacle.

2. Push the back panel power switch (14) up (on). The red stand-by LED (2)

illuminates.

3. Press the power button (1) on the front panel. The blue power indicator (3)

illuminates and you hear a click.

There will be a brief delay before the component can be put in the operational mode
after the back panel power switch is first pushed up.


Krell recommends leaving the amplifier in the stand-by mode unless you will not be
playing music for a long time.

IMPORTANT
Always turn the amplifier off before changing input connections, and mute or fully
attenuate the preamplifier level when switching sources.

The amplifier has tremendous reserves of power and safely drives loudspeakers to
extremely high sound pressure levels. However, use care when setting high playback
levels and lower the volume level at any sign of loudspeaker distress.

USING A DEDICATED WALL SWITCH

The amplifier can also be powered on from an AC wall receptacle with a dedicated
switch, rather than from the front panel power button. Please contact your authorized
Krell dealer, distributor, or Krell for more information before you connect the amplifier to
a dedicated AC wall outlet with a switch.
