On/Off and Stand-by Operation

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

After the Evolution 222 is connected to your system and to AC power, and the front panel display (3) has stopped scrolling, begin operation:

1.Press the power button on the preamplifier front panel or the pwr key (1) on the remote control. The stand-by/power LED (7) turns blue, and the front panel display reads INITIALIZING. The front panel display shows the factory default input: S-1, and level: -INF. The Evolution 222 is now in the operational mode.

2.With the preamplifier output muted or the volume fully attenuated, select a source manually using the input select buttons or the remote keys (8, 9, 10,

11). Start playing the source. Use the level control knob or level keys (14) to set the volume to a comfortable listening level.

3.To return to the stand-by mode, press the power button or pwr key.

Krell recommends leaving the Evolution 222 in the stand-by mode when it is not playing music. Turn the Evolution 222 off when the system is not being used for an extended period of time.
