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
sys-
tems
using
the
12
V
trigger
and
the
bridg-
ing
capability.
The
KAV-150a
uses
proven
Krell®circuits
built
with
the
same
high
qual-
ity
resistors,
output
devices,
and
internal
electrical
components
used
in
all
other
Krell®products.
From
input
to
output,
the
KAV-150a
uses
discrete,
fully
complemen-
tary
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.

manual
contains

these
details

sive
