Introduction

Thank you for your purchase of the Krell

®

KAV-150a Power Amplifier. The name
Krell® has always represented components

that are the premier performers in their

product categories. The KAV-150a power
amplifier continues in this Krell® tradition

The KAV-150a is a stereo amplifier that
may be bridged into monaural operation.

Designed as a compact component with
exceptional sound, the KAV-150a may be

interfaced easily into multi-amplifier sys­tems using the 12 V trigger and the bridg-

ing capability. The KAV-150a uses proven

Krell®circuits built with the same high qual­ity resistors, output devices, and internal

electrical components used in all other

Krell®products. From input to output, the

KAV-150a uses discrete, fully complemen­tary circuitry. All circuits up to the driver
stage operate in pure Class A. The

KAV-150a employs a wide bandwidth

design with a very low negative feedback for

sonic accuracy throughout the frequency

spectrum.
This owner’s reference manual contains

important information on the placement,

installation, and operations of the KAV-150a.

Please read this information carefully. A

thorough understanding of these details

will help insure satisfactory operation and a

long life for the KAV-150a and related sys-

tem components.

The KAV-150a is backed by a comprehen­sive customer satisfaction policy and one

of the most advanced service facilities in
the industry. For detailed information on
