Section Five

It is now safe to place the rest of the system in stand-by.

Powering Off

Krell recommends leaving Evolution amplifiers powered down (in the stand-by mode, with the back panel power breaker switch on) between listening sessions. Turn the amplifier off using the power breaker switch (10), and disconnect the amplifier from AC power when the system is not being used for an extended peri- od of time.

Increase the volume control to the desired listening level.

With the preamplifier muted or its volume completely lowered, select a source.

5. To return the amplifier to stand-by, press the power button on the front panel. The power status indicator turns red, and the amplifier is in the stand-by mode.

Evolution Amplifier Operation

The Evolution amplifiers are easy to operate.

IMPORTANT

When powering up any system, turn the amplifier on last. When powering down, turn it off first. This will prevent any turn-on and turn-off thumps in your loudspeakers. Always mute or fully attenuate the preamplifier level when switching sources. Do not change input connections to the amplifier when the amplifier is on.

Krell amplifiers have large reserves of clean power that can safely drive loudspeakers to higher sound pressure levels than other amplifiers. Use care when setting high play- back levels, and lower the volume level at the first sign of loudspeaker distress.

On/Off and Stand-by Operation

1. Move the back panel power breaker switch (10) to the up position to place the amplifier in stand-by mode. The power status indicator (2) illuminates in red.

2. Press the silver power button (1) on the amplifier front panel. The power status indicator (2) illuminates in blue.

The initial power-up phase lasts approximately 30 seconds from the moment the back panel power breaker switch is placed in the up position. If the power button is pressed during this period, the power status indicator flashes blue for the remainder of the initial power-up phase. When the initial power-up phase is complete, the power indicator illuminates in blue and is no longer flashing. The amplifier is in the operational mode.
