Introduction
Krell S-275
Thank you for your purchase of the Krell S-275 Stereo 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-275
is a power amplifier with big power—275 Watts per channel—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, result-
ing in more accurate signal transfer and enhanced reliablilty.
The S-275 is a slim line design allowing two amplifiers to fit into a
space normally occupied by one. For systems requiring higher
power, the S-275 can be configured for monaural operation by set-
ting a switch on the rear panel. Power output increases to 550
Watts into 8 Ohms. A 6 dB gain switch provides a channel balanc-
ing tool for systems using a combination of balanced and RCA
style connections.This owner's reference contains important infor-
mation on the placement, installation, and operation of the S-275.
Please read this information carefully. A thorough understanding of
these details will help ensure satisfactory operation and long life
for your S-275 and related system components.
