as floating
signal-or
control-voltage
attenuators
wherever
they
might
be needed.
The
mixer
is
good down
to
DC
voltages and
can be
used
to mix
control signals
as
well as audio signals.
4.631 The PANNING
POTENTIOMETER (Panpot)
has
one
input,
normally from the
mixer. When
the control slider
is
centered,
the
input signal
is sent
in equal proportions
to
the left
and
right
outputs.
As the
slider
is moved
to
the left or
right^
the signal level
is decreased
on
the opposite
channel until
at either extreme position,
it disappears
entirely.
The
audible
effect
is
that
by means
of
the panpot
it
is pos-
sible
to
"position"
a
signal anywhere in the stereo
output
of
the
2600.
4.64
The REVERBERATION
UNIT has
one input,
normally pre-
wired
from
the
mixer output. The
signal
presented
to this
input is
equalized
and sent to
a
pair
of reverb
springs.
The spring
output, am-
plified, is sent
to
two
attenuators; the signal to one
of
them
is
phase-
inverted
to
create
a strong sense of
spaciousness
in
the reverberated
output.
From the
left-channel
attenuator
the signal
passes
directly
to
the left-channel
output
of the
2600;
the right-channel
attenuator
output
is fed through the
REVERB OUTPUT jack
to the
right-
channel output
of the
2600.
Inserting
a patch cord into the
REV
OUT
jack
interrupts
this
connection
and
makes
a
reverberated signal
available
for
feeding
to other functions
in
the
2600.
4.65
Outputs from
the
PANPOT,
REVERB
UNIT,
and LEFT
and
RIGHT INPUTS (near
the
upper
right
corner of the
2600)
are
com-
bined at summing
points for each channel.
The LEFT CHANNEL
signal
is
available
at
the LEFT
OUTPUT jack
and
is internally fed
to
a
1-watt power
amplifier which
drives the LEFT CHANNEL
MON-
ITOR SPEAKER
in the 2600. The
RIGHT CHANNEL
signal is avail-
able
at the
RIGHT
OUTPUT jack and
is
fed internally
to
a 1-watt
power amplifier
which drives the
RIGHT CHANNEL
MONITOR
SPEAKER.
The
volume from each
speaker is governed
by
an atten-
uator immediately next
to
it.
