WARNINGS

Thank you for your purchase of the Krell Evolution 222 Stereo Preamplifier. The Evo- lution 222 features Krell Current Mode circuit topologies, Krell CAST technology, and a robust power supply for exceptional audio performance. A thoughtful suite of menu options ensures that the Evolution 222 can be customized for the greatest ease of operation.

Please contact your authorized dealer, distributor, or Krell if you have any questions not addressed in the owner’s reference.

The preamplifier’s front panel provides power on, input and zone selection, level control, menu functions, and status display. The rear panel allows connection to audio sources, power amplifiers, AC power, and other system components.

The remote control provides power, preamplifier, level control, navigation and customization functions, CD and DVD player controls and menu configuration.

Do not place the preamplifier where it could be exposed to dripping or splashing.

Do not remove or bypass the ground pin on the end of the AC cord. This may cause radio fre- quency interference (RFI) to be introduced into your playback system.

The ventilation grids on the top and bottom of the preamplifier must be unobstructed at all times during operation. Do not place flammable material on top of or beneath the component.

Turn off all systems’ power before connecting the preamplifier to any component.

Make sure all cable terminations are of the highest quality, free from frayed ends, short circuits, or cold solder joints.

THERE ARE NO USER-SERVICEABLE PARTS INSIDE ANY KRELL PRODUCT

Note

Save all packing materials. If you need to ship the Evolution 222 in the future, repack the unit in its original packaging to prevent shipping damage.

1.Open the shipping box and remove the top layer of foam. You will see these items:

1	Preamplifier chassis	2	AAA remote batteries
1	IEC connector (AC power) cord	1	T-10 Torx wrench for remote
1	Remote control	1	Quick Setup Guide

2.Carefully remove all items from the shipping box.

3.Place the preamplifier in a safe location and remove the protective plastic wrap- ping.

We recommend that you place the preamplifier on a firm, level surface, away from excessive heat, humidity, or moisture. The preamplifier requires at least two inches (5 cm) of clearance on each side and at least two inches (5 cm) of clearance above to provide adequate ventilation. Installations inside cabinetry may need extra venti- lation.

The Evolution 222 preamplifier has superb regulation and does not require a dedi- cated AC circuit. Avoid connections through extension cords or multiple AC adapters. High quality 15 amp AC strips are acceptable. The use of AC line condi- tioning devices is not recommended. The features provided by these devices are already on board the Evolution 222.
