Operating Your KAV–400xi

Amplifier Operation

This section provides information about operating the KAV–400xi. The KAV–400xi provides basic input selection and volume control operation from the front panel. The remote control includes addi- tional preamplifier and volume functions as well as compact disc transport and amplifier controls. See Remote Control Only, on page 9, for more information.

After the KAV–400xi is connected to AC power and in the stand-by mode, use the power button or key (1) to switch the component to the operational mode. The blue power LED (2) illuminates.

The KAV–400xi Remote Control Integrated Amplifier is easy to operate. However, great care should be exercised when operating a system that includes the KAV–400xi, because of the amplifier’s power output. Switching between active sources without muting the preamplifier output, or bumping/miscuing a device, can gener- ate large transients at low frequencies. The KAV–400xi may gen- erate enough power with these transients to damage most loud- speakers. To avoid damage, be sure to switch all sources with the preamplifier level either muted or fully attenuated. Do not change inputs to the amplifier while the amplifier is on.

Note	Krell amplifiers have large reserves of clean power and can safely drive
	loudspeakers to higher sound pressure levels than other amplifiers.
	However, use care when setting high playback levels and lower the vol-
	ume level at any sign of loudspeaker distress.

ON/OFF AND STAND-BY OPERATION

When powering up any system, always turn amplifiers on last. When powering down, always turn amplifiers off first.

1.When the amplifier is in stand-by mode, with the red stand-by LED (3) illuminated, turn the amplifier on by pressing the power button on the front panel or the power key on the remote control (1). There is an audible click. The blue power LED (2) illuminates, and the red stand-by LED (3) turns off. The KAV–400xi is now in the operational mode.

2.With the amplifier in the mute position, or the volume control fully attenuated, select a source from the front panel or the remote control (5).
