CONNECTIONS
WITH
1.
IMPEDANCE
Input
and
output
impedances
should
always
be
considered
when
connecting
this
unit
to
other
equipment.
Impedance
is
the
resistance
value
against
alternating
currents
such
as
sound
signals
and
the
unit
of
measurement
is
Q
(Ohm).
If
the
output
impedance
of
a
given
unit
does
not
match
the
input
impedance
of
the
other,
sound
distortion
or
even
equipment
breakdown
could
occur.
In
general,
the
rule
is
that
output
impedance
should
be
low
(low
out)
and
input
impedance
should
be
high
(high
receive).
Refer
to
SPECIFICATIONS
in
page
19
for
input/output
impe¬
dance
of
this
unit.
NOTE:
Always
use
a
Direct
Box
when
interconnec¬
ting
outputs
indicated
in
watts,
(W)
such
as
that
of
a
power
amplifier,
with
a
high
impedance
input.
If
this
precaution
is
not
followed,
severe
damage
may
result.
In
this
function,
only
one
of
either
1
(RCA
pin
jack)
or
2
(stereo
phone
jack)
will
be
effective
(Refer
to
MONITOR
OUT
selector
(27)).
The
polarity
of
2
(stereo
phone)
is
L
for
the
TIP
and
R
for
the
RING.

THE
TAPE
TRIMMER
This
trimmer
is
for
matching
the
input
level
of
this
units’
TAPE
IN
jack
(36)
with
a
recorder
whose
output
level
is
other
than
-lOdBV.
Although
its
variable
range
is
-16dBV
~
+
20dBV,
it
is
adjusted
to
-lOdBV
at
leaving
the
plant
and
Fostex
multitrack
recorders
such
as
Model
E-16,
E-8
and
80
can
be
connected
without
any
adjusting.

Matching
the
level
of
the
external
equipment
connec¬
ted
to
the
INPUT
jacks
(33)
and
(34)
of
this
unit
is
done
by
the
TRIM
(1)
controls.
Adjust
so
that
the
PEAK
LED
(6)
does
not
frequently
flash
on
the
signal
peaks.
As
noise
and
distortion
is
the
least
in
the
range
of
0
±
5
(dB)
of
the
INPUT
faders
(17),
it
is
recommended
to
preset
them
within
this
range,
then
adjust
the
level
with
TRIM
(1).
During
this
operation,
if
the
PFL
button
(15)
and
INPUT
SOLO
button
(16)
are
pressed
in
advance,
the
prefader
and
post-fader
levels
and
tone
can
be
conveniently
checked.
However,
as
the
PEAK
LED
(6)
will
be
lit
during
overloading
at
EQ
(7),
each
gain
of
EQ
(7)
should
be
kept
flat
when
adjusting
TRIM
(1).
After
setting
TRIM
(1),
if
the
PEAK
LED
should
be
lit
during
testing
of
the
tone
by
EQ
(7),
there
is
overloading
at
the
EQ
stage
(7)
and
the
corresponding
gain
should
be
decreased,
or
re-adjust
TRIM
(1).
