SPEAKER OUTPUT JACKS: Two parallel outputs are provided for each channel. The minimum total impedence that should be connected to any single channel is 4 Ohms. B. OUTPUT IMPEDENCE SELECTOR: This switch should be set to the impedence of the speakers. For example, if you have connected an 8 Ohm speaker to each channel, the switch should be put in the 8 Ohm position. The switch enables the user to change in and out of tube emulation mode without a significant change in output level. Because the amplifier reacts with the speaker in tube mode, though, some change in level, especially a boost of highs and lows, should be expected. C. INPUTS: One input is provided for each channel. The inputs to the amplifier can be unbalanced or balanced 1/4 inch plugs. For balanced lines, the tip is the "+" signal, the ring is the "-" signal and the sleeve is ground. Connecting a single mono source to channel one will cause the input to be sent to both amplifier channels, each with its own volume and presence controls. Connecting a single source to just channel two will send the signal only to channel two. Connecting two sources (or the stereo outputs of one source) to both channels will enable two channel operation, with each having its own respective volume and presence controls. CAUTION: This amplifier is equipped with a grounding type supply cord to reduce the possibility of leakage current. Be sure to connect to a grounded receptacle. Operation from an ungrounded (two pronged) AC receptacle requires a three to two contact grounding type adaptor. Be sure to connect the adaptor's grounding lead to a good earth ground. DO NOT ALTER THE AC PLUG.

A.
SPEAKER
OUTPUT
JACKS:
Two
parallel
outputs
are
provided
for
each
channel.
The
minimum
total
impedence
that
should
be
connected
to
any
single
channel
is
4
Ohms.
B.
OUTPUT
IMPEDENCE
SELECTOR:
This
switch
should
be
set
to
the
impedence
of
the
speakers.
For
example,
if
you
have
connected
an
8
Ohm
speaker
to
each
channel,
the
switch
should
be
put
in
the
8
Ohm
position.
The
switch
enables
the
user
to
change
in
and
out
of
tube
emulation
mode
without
a
significant
change
in
output
level.
Because
the
amplifier
reacts
with
the
speaker
in
tube
mode,
though,
some
change
in
level,
especially
a
boost
of
highs
and
lows,
should
be
expected.
C.
INPUTS:
One
input
is
provided
for
each
channel.
The
inputs
to
the
amplifier
can
be
unbalanced
or
balanced
1/4
inch
plugs.
For
balanced
lines,
the
tip
is
the
"+"
signal,
the
ring
is
the
"-"
signal
and
the
sleeve
is
ground.
Connecting
a
single
mono
source
to
channel
one
will
cause
the
input
to
be
sent
to
both
amplifier
channels,
each
with
its
own
volume
and
presence
controls.
Connecting
a
single
source
to
just
channel
two
will
send
the signal
only
to
channel
two.
Connecting
two
sources
(or
the
stereo
outputs
of
one source)
to
both
channels
will
enable
two
channel
operation,
with
each
having
its
own
respective
volume
and
presence
controls.
CAUTION:
This
amplifier
is
equipped
with
a
grounding
type
supply
cord
to
reduce
the
possibility
of
leakage
current.
Be
sure
to
connect
to
a
grounded
receptacle.
Operation
from
an
ungrounded
(two
pronged)
AC
receptacle
requires
a
three
to
two
contact
grounding
type
adaptor.
Be
sure
to
connect
the
adaptor's
grounding
lead
to
a
good
earth
ground.
DO
NOT
ALTER
THE
AC
PLUG.
