Evolution Two Operation
The Evolution Two Monaural Preamplifer is easy to operate. Instructions follow for
on/off and stand-by operation.
IMPORTANT
Always mute or fully attenuate the preamplifier level when switching sources.
Do not change input connections to the amplifier when the amplifier is on.
Use care when setting high playback levels. Always lower the volume level at the first
sign of loudspeaker distress.
On/Off and Stand-by Operation
(Linked Mode)
When powering on any system, turn on amplifiers last. When powering down, turn
off amplifiers first.
After the Evolution Two is connected to your system and to AC power, and the
front panel display (15) has stopped scrolling, begin operation:
1. Press the power button on either preamplifier chassis front panel or the pwr
key (3) on the remote control. The blue backlights illuminates, the red stand-by
LEDs (4) turn off, and the front panel displays read INITIALIZING. The front panel
displays shows the factory default input: S-1 , and level: -INF . The Evolution Two
is now in the operational mode.
2. With the Evolution Two preamplifier output muted or the volume fully attenuat-
ed, select a source manually using the front panel input select buttons or the
input select keys on the remote control (8, 9, 10, 11). Start playing the source.
Use the level control knob or level keys (16) to set the volume to a comfortable
listening level.
3. To return the Evolution Two to the stand-by mode, press the power button or
pwr key.
Krell recommends leaving the Evolution Two in the stand-by mode when it is not
playing music. Turn the Evolution Two off when the system is not being used for
an extended period of time.
