OVERVIEW

Getting Started

WARNINGS

This product complies with the EMC directive (89/336/EEC) and the low-voltage directive (73/23/EEC).

The Evolution Series consists of six amplifier models. Stereo models include the Evolution 302 and 402 amplifiers. The Evolution 403 is a three-channel amplifier and the Evolution 400, 600, and 900 are monaural amplifiers. A pair of Evolution monaural amplifiers are required for stereo operation.

Evolution amplifiers can be configured to accommodate any sophisticated music or home theater system. In addition to manual operation, the amplifiers can be operated remotely by a 12 V trigger, or by using the remote control of other Krell components. Evolution CAST, voltage balanced, and single-ended inputs are on the back panel. A protection circuit shuts the amplifier down if short circuit or over-temperature conditions are detected.

This guide outlines the basic steps for unpacking, placing, connecting, and operat- ing a Evolution Series Power Amplifier. Please contact your authorized dealer, dis- tributor, or Krell if you have any questions not addressed in the owner’s reference.

The Evolution amplifier must be placed on a firm, level surface where it is not exposed to dripping or splashing.

The ventilation grids on the top of all Evolution amplifiers and the ventilation grids on the back of the Evolution 302 and 400 amplifiers must be unobstructed at all times during operation. Do not place flammable material on top of or beneath the component.

Before making connections to the Evolution amplifier, ensure that it is off and the pream- plifier is in mute or stand-by mode. Make sure all cable terminations are of the highest quality and free from frayed ends, short circuits, or cold solder joints.

THERE ARE NO USER-SERVICEABLE PARTS INSIDE ANY KRELL PRODUCT.

Unpacking

Note

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

Placement

Two people are needed to remove an Evolution amplifier from its shipping box safe- ly and easily.

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

1	Evolution amplifier	1 packet containing this quick setup
1	20 amp AC power cord	guide and the warranty registration
1	12 VDC (12 V trigger) cable	card

2.Orient the shipping box so that one person stands at the front of the amplifier and one person stands at the back of the amplifier. Both people need to grab a pair of the cardboard handle cutouts (one pair located at the front of the amplifier and one pair located at the back of the amplifier) and simultaneously lift the amplifier straight up, out of the carton.

3.Place the amplifier in a safe location and remove the protective plastic wrapping.

Place the amplifier on a firm, level surface, away from excessive heat, humidity, or moisture. Each Evolution amplifier requires at least two inches (5 cm) of clearance on each side and at least eight inches (20 cm) of clearance above the component to provide adequate ventilation. If you place the amplifier in a closed cabinet, you may need to modify shelf spacing or use small fans to increase ventilation. When the front and back of a cabinet are open, the air space between the chassis and shelf must be unobstructed.

Place the amplifier(s) as close to the loudspeakers as possible. While Evolution CAST technology permits long cable lengths, keep loudspeaker cable lengths to a minimum.
