Krell S-150m

Introduction
Thank you for your purchase of the Krell S-150m Mono Power
Amplifier. This configurable power amplifier has a discrete signal
path from input to output and employs a wide bandwidth design
with low negative feedback for sonic accuracy throughout the fre-
quency spectrum. All circuits up to the driver stage are balanced
and pure Class A.
Krell’s new surface mount technology (SMT) means that the S-
150m is a power amplifier with big power—150 Watts that does not
require big space. SMT allows individual circuit elements to be
placed very closely together. This shortens signal paths and allows
circuit elements to operate at the same temperature, resulting in
more accurate signal transfer and enhanced reliablilty.
The S-150m is a slim line design allowing five amplifiers to fit into
a space normally occupied by one. This owner’s reference con-
tains important information on the placement, installation, and
operation of the S-150m. Please read this information carefully. A
thorough understanding of these details will help ensure satisfacto-
ry operation and long life for your S-150m and related system
components.
