Remote Control

Operation

Full Power Balanced amplifiers are compatible with the remote controls included with Krell pre- amplifiers, the Home Theater Standard 7.1, and the KPS 25sc Krell Playback System.

Please contact your authorized Krell dealer, dis- tributor, or Krell to purchase a remote control for Full Power Balanced amplifiers.

Full Power Balanced amplifiers can be located in a room or space close to the speakers but out of sight, and powered on or off remotely from the listening room, through a control amplifier. See Krell Link Connections, on page 13.

HOW TO TURN OFF

THE AMPLIFIER LEDs

The amplifier must be in the stand-by mode with the rear panel power breaker switch on. While holding the silver power button in, press the power key on the remote control. After the amplifier finishes its turn-on sequence, the front panel blue LEDs turn off. The blue LEDs remain off throughout normal operation as long as the amplifier’s rear panel power breaker switch is not turned off.

HOW TO TURN ON

THE AMPLIFIER LEDs

With the amplifier in the stand-by mode, turn the rear panel power breaker switch to the off position. Then turn the rear panel power break- er switch back to the on position. The next time the amplifier is powered up from the front panel or the remote control, the blue LEDs illuminate during the turn-on sequence.

HOW TO SWITCH BETWEEN KRELL CAST AND XLR INPUTS

Press the meter key on a Krell remote to switch between CAST inputs and the balanced XLR inputs.

Full Power Balanced amplifiers default to CAST operation upon startup, if the amplifier is turned off from the rear panel power breaker switch and a CAST source and cable are connected to the CAST inputs. The operational mode does not change if the Full Power Balanced amplifier is in stand-by mode.

USING A DEDICATED WALL OUTLET AND SWITCH

Full Power Balanced amplifiers can be powered on from an AC wall receptacle with a dedicated switch, rather than from the front panel power button or optional remote control.

Please contact your authorized Krell dealer, dis- tributor, or Krell for more information before you connect your Full Power Balanced amplifier to a dedicated AC wall outlet with a switch.
