Connecting the Evolution 222 to Your System

Krell recommends using its proprietary Krell CAST system for unparalleled sonic per- formance for connections between the preamplifier and other CAST-equipped compo- nents. Krell CAST uses flexible interconnecting cables that can be drawn through tight spaces and concealed.

The Evolution 222 also offers balanced operation. This not only minimizes sonic loss but is also immune to induced noise, especially for installa- tions using long cables.

Operating the

Evolution 222

Channel Balance Adjustment

Position the preamplifier where you intend to use it in your system.

1.Neatly arrange and organize wiring to and from the preamplifier and all compo- nents. Separate the AC wires from any audio cables to prevent hum or other unwanted noise from being introduced into the system.

2.Connect the outputs of your source equipment to the appropriate CAST (18), balanced (15), single-ended (16), or tape inputs (17) on the Evolution 222.

3.Connect the main outputs (20) on the Evolution 222 to your amplifier’s inputs.

4.Connect the supplied AC power cord to the IEC power cord receptacle (26) of the preamplifier.

5.Plug the other end of the AC power cord into AC power. The display (3) scrolls through EVOLUTION 222 SOFTWARE VERSION, and the stand-by/power LED (7) illumi- nates red, indicating that the Evolution 222 is in stand-by mode. When the scrolling stops, the Evolution 222 is ready to be powered on.

Note

Use only the power cord provided with the Evolution 222 to make the connection to AC power. Operation with a power cord other than the one supplied by Krell can induce noise, limit current, or otherwise impair the ability of the preamplifier to perform optimally.

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

1.Press the power button (1) on the front panel, or the remote control power key. The standby/power LED turns blue. The 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 front panel input select buttons (8, 9, or 10) or the remote input select keys. Start playing the source. Use the level control knob (14) or the remote level keys to set the volume to a comfortable level.

3.To return the preamplifier to the stand-by mode, press the power button (1) or remote power key. (We recommend leaving the Evolution 222 in the stand-by mode when it is not playing music.)

The balance function allows adjustment of the left and right balance. The options are:

1.Press the preamplifier menu button (5), then use the level control knob, or the remote control up and down keys to select: BALANCE.

2.Press the enter button (6) or remote enter key. The display shows the default mode: CENTER.

3.Use the level control knob, or the up and down keys, to select the desired bal- ance option from 0 to +5 dB in .5 dB increments, left or right.

4.Press the enter button or key to confirm the selection. The display reads:

BALANCE.

5. Press the menu button to exit the menu.
