Operating the S–1500 Amplifier

ON/OFF AND

OPERATION

IMPORTANT: PROTECTION CIRCUITRY

When powering up your system, turn the amplifiers on last. When powering down your system, turn amplifiers off first. The proce- dures for operating the S–1500 Multi-channel Amplifier follow.

1.Plug the AC power cord into the amplifier’s IEC connector (8).

2.Plug the other end of the AC power cord into the AC wall outlet.

3.The LED (2) illuminates red to indicate it is in stand-by mode.

When the amplifier is first plugged in, there is a brief delay before it can be put in the operational mode. Please wait approximately 10 seconds.

If the LED flashes red when the amplifier is in the stand-by mode, unplug the amplifier from the AC wall outlet to reset the protection circuitry. Check the loudspeakers and loudspeaker cables for potential short circuits before plugging the amplifier back into the wall outlet.

IMPORTANT: CHANGING INPUTS, HIGH PLAYBACK LEVELS

4.Press the power button (1) on the front panel. The LED (2) illuminates blue and you will hear a click. The amplifier is in the operational mode.

Krell recommends leaving the S–1500 amplifier in the stand-by mode unless you will not be playing music for a long time.

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

The S–1500 amplifier has tremendous reserves of power, and safe- ly 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.
