need to ship the Evolution amplifier

in the future, repack the unit in its

original packaging to prevent ship-

ping damage.

Unpacking

Getting Started

The Evolution Series consists of six amplifier models. Stereo models include the

E

volution 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.

E

volution 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.

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 20 amp AC power cord

1

12 VDC (12 V trigger) cable

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 r

emove 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.
