MIXER
INTRODUCTION
The
system
you
have
purchased
is
a
very
portable
package
with
the
flexibility
of
mixers
twice
the
size
at
twice
the
price.
The
701R
™
features
seven
channels,
excellent
4-band
equalization,
rack-mount
versatility,
balanced
inputs,
and
balanced
outputs.
Rack-mountable
mixers
have
a
special
place
in
sound
rein¬
forcement
applications,
and
many
times
no
other
type
pro¬
duct
will
suffice.
The
701R
requires
a
very
low
profile,
vertical
mounting
space,
and
is
exceptionally
thin,
front
to
back.
These
dimensions
are
critical,
as
rack
space
is
usually
a
premium
consideration.
The
input
circuitry
has
tremendous
dynamic
range
and
will
handle
sound
reinforcement
applications
with
ease.
As
you
read
the
enclosed
literature,
please
try
to
learn
as
much
as
possible
about
the
product
so
your
job
of
sound
reproduction
will
be
easier
and
the
results
will
be
an
overall
improved
performance.
The
person
doing
sound
or
installing
sound
systems
is
actually
an
extension
of
the
performance
and
should
master
the
sound
equipment,
just
as
a
musician
masters
his/her
instrument.
INPUT
GAIN
CONTROL
(1)
The
Input
Gain
Control
of
the
701R
Mixer
utilizes
a
dual
con¬
trol
element
configuration
so
that
input
attenuation
and
gain
adjustment
occur
simultaneously.
This
arrangement
allows
the
vital
input
circuitry
to
handle
almost
any
input
voltage
from
low
level
mics
to
speaker
levels.
The
function
and
operational
requirements
of
this
input
gain
stage
are
conventional
and
should
present
no
operational
difficulty.
MONITOR
SEND
CONTROL
(2)
The
monitor
send
control
is
the
channel
mixing
element
for
determining
the
all
important
monitor
mix.
Signals
for
the
monitor
sends
are
obtained
right
after
the
input
preamp
and
before
the
channel
EQ.
These
are
referred
to
as
pre
monitor
sends,
i.e.
they
are
before
the
channel
equalization
and
chan¬
nel
level
controls.
This
makes
them
independent
of
these
con¬
trols
and
any
changes
made
to
the
EQ
or
channel
level
will
not
affect
the
monitor
system.
Having
the
monitor
send
with
pre-EQ
capability
is
absolutely
vital
to
avoid
feedback
of
the
monitor
system
when
EQ
and
normal
incremental
setting
variations
are
made
in
the
channel
fader
during
the
course
of
the
performance.
HIGH
FREQUENCY
EQ
(4)
This
control
determines
the
relative
boost
or
cut
of
the
highest
frequency
adjustment
on
this
console
and
features
a
15
dB
boost
or
cut
at
15
kHz.
This
control
operates
in
a
shelving
configuration
which
prevents
any
additional
gain
above
the
usable
audio
spectrum
from
causing
undesirable
hiss
and
instability.
The
zero
setting
indicates
a
flat
frequency
response
with
no
alteration
of
the
extreme
highs
and
clockwise
indicates
a
boost
while
counterclockwise
indicates
a
cut
or
a
dip
in
the
high
frequencies.
Usually
feedback
is
not
much
of
a
problem
at
very
high
frequencies,
but
the
control
is
very
important
for
giving
that
sibilant
sound
on
the
extreme
highs
and
on
the
s's
and
t’s
of
the
vocals.
HIGH
MID
FREQUENCY
EQ
(5)
This
control
determines
the
relative
boost
or
cut
of
the
upper
mid
or
lower
treble
frequencies
and
is
capable
of
15
dB
boost
or
cut
at
3
kHz.
A
balance
of
mid
range
frequencies
should
begin
with
a
flat
setting
of
zero
so
that
adjustments
may
be
made
with
a
cut
or
a
boost
of
this
control.
The
action
of
the
control
is
peak/notch
type
which
interfaces
with
the
adjacent
equalizers
in
a
smoother
manner
to
yield
optimum
summing
capability
of
the
channel
equalization.
Usually
a
minus
set¬
ting
of
this
control
is
desirable
to
eliminate
harshness
with
most
systems
and
control
feedback.
LOW
MID
FREQUENCY
EQ
(5)
This
control
is
operational
in
the
lower
mid
range
or
upper
bass
region
and
is
capable
of
15
dB
boost
or
cut
at
400
Hz.
This
EQ
control
exhibits
a
peak/notch
characteristic
which
operates
smoothly
with
the
adjacent
equalizer
controls
and
allows
proper
balancing
of
the
upper
bass
and
lower
mid
range
frequencies.
This
control
is
very
vital
for
controlling
the
mid
range
frequencies
of
the
human
voice
when
vocals
are
being
amplified.
(Most
vocals
require
a
slight
minus
setting
of
this
control.)
LOW
FREQUENCY
EQ
(6)
This
control
is
capable
of
15
dB
boost
or
cut
at
60
Hz
and
demonstrates
a
shelving
characteristic
so
that
excessive
lows
are
not
boosted
below
the
usable
range
of
typical
sound
rein¬
forcement.
The
shelving
action
of
this
circuit
has
proven
to
yield
much
more
satisfying
and
effective
equalization
characteristics
than
some
of
the
wide
open
EQ
circuits
claim¬
ing
20
to
25
dB
boost
and
cut.
Care
should
be
taken
with
the
low
frequency
control
not
to
over-boost
lows
on
any
particular
instrument
or
vocal
due
to
the
fact
that
tremendous
amounts
of
headroom
will
be
used
up
and
a
general
muddiness
will
be
apparent
in
the
sound
system
reproduction.
Woofers
may
also
be
blown
much
more
easily
with
extreme
low
frequency
boost.
EFFECTS
SEND
CONTROL
(7)
This
effects
control
is
post
and
is
effected
by
the
equaliza¬
tion
of
each
channel
and
its
level
is
also
effected
by
the
chan¬
nel
level
control.
NOTE:
This
action
is
totally
opposite
from
the
monitor
send
controls
on
each
channel
which
are
pre
and
unaffected
by
other
features
on
the
channel.
When
the
ef¬
fects
send
control
is
activated
on
any
particular
channel,
a
signal
is
sent
through
the
master
effects
level
control
and
ap¬
pears
at
the
effects
output
on
the
rear
panel.
This
output
may
be
patched
into
many
various
effects
devices.
(See
effects
patch
diagrams.)
NOTE:
The
internal
reverb
drive
receives
its
signal
from
the
effects
send
control
also
and
a
signal
is
then
sent
to
the
master
reverb
control
in
the
master
section
in
order
for
the
internal
reverberation
system
to
function.
When
operating
an
outboard
effects
device
and
the
internal
reverb
system
simultaneously,
the
channel
send
control
on
the
ef¬
fects
mix
must
be
optimized
for
the
amount
of
both
effects
on
a
particular
channel.
PAN
CONTROL
(8)
This
control
is
most
often
used
to
assign
certain
channels
to
one
or
both
subs.
The
action
is
conventional
and
clockwise
rotation
assigns
to
sub
“B”
while
counterclockwise
rotation
assigns
to
sub
“A”.
A
setting
of
12:00
places
the
channel
equally
in
both
subs.
NOTE:
When
recording,
this
control
may
be
used
for
stereo
imaging
(left,
right,
or
both).
CHANNEL
LEVEL
CONTROL
(9)
The
channel
level
is
the
output
control
that
determines
the
mix
of
the
various
channels
into
the
master
mix.
This
control
should
be
operated
near
the
zero
indication
of
unity
gain
whenever
possible
and
the
input
gain
control
should
be
ad¬
justed
accordingly
for
each
instrument
or
vocal,
etc.
NOTE:
Above
the
zero
point
on
the
channel
level
slider
there
is
14
dB
of
gain
as
you
increase
to
the
upper
limit
of
the
level
con¬
trol.
It
is
virtually
impossible
to
have
too
much
gain
during
typical
sound
reinforcement
situations
and
when
a
low
gain
situation
presents
itself
it
is
nice
to
be
able
to
increase
the
channel
gain
by
14
dB
with
the
level
control
and
possibly
avoid
having
to
readjust
input
gain
sensitivity.
NOTE:
Operation
above
“0”
increases
system
noise.
Operation
below
“0”
decreases
system
noise
but
at
the
sacrifice
of
system
headroom.
MASTER
SECTION
—
FRONT
PANEL
As
the
name
implies,
the
master
section
of
the
701R
Mixer
contains
all
of
the
controls
for
the
respective
mixing
busses
and
supplementary
controls
to
allow
other
special
functions
to
be
achieved.
The
master
level
controls
should
be
set
in
such
a
manner
that
they
are
close
to
the
center
of
their
travel
(0
dB)
to
take
advantage
of
the
maximum
control
action.
It
is
poor
practice
to
set
up
the
input
channels
at
too
high
a
level
which
will
require
the
user
to
run
the
main
levels
at
a
low
set¬
ting
to
achieve
the
desired
result.
Operation
in
this
manner
will
cause
the
operator
to
lose
his
“range"
of
the
control
ac¬
tion
with
all
the
gain
located
in
one
element
while
the
other
is
in
the
infinity
position.
This
manner
of
operation
also
tends
to
create
headroom
problems.
Best
practice
calls
for
most
con¬
trols
to
be
operated
near
the
middle
of
their
operating
range
to
allow
mixing
control
margins.
Remember
that
while
mix¬
ing
it
is
important
to
allow
yourself
adequate
margins
within
which
to
operate.
By
using
any
of
the
controls
in
their
extreme
positions,
you
have
effectively
reduced
your
operational
latitude.
These
master
controls
allow
the
operator
complete
flexibility
of
functions
and
should
allow
almost
any
mixing
situation
to
be
handled.
As
with
any
reasonably
complex
system,
ex¬
perience
and
operator
knowledge
of
the
equipment
are
essen¬
tial
for
satisfactory
performance.
The
mixer,
like
the
musician’s
instrument,
should
be
practiced
on
and
learned.
To
properly
operate
a
mixer
during
a
performance
requires
thorough
knowledge
and
trained
reflexes
to
allow
proper
responses
under
the
stress
of
demanding
and
sometimes
sudden
situations.
Please
note
that
the
master
level
controls
have
a
0
dB
indica¬
tion.
Operating
within
these
ranges
will
assure
the
best
com¬
bination
of
signal
to
noise
ratio
and
headroom.
SUB
MASTERS
(A
&
B)
(10)
The
subs
(A
&
B)
are
the
main
output
level
controls
and
regulate
the
signal
levels
being
supplied
to
the
output
jacks
on
the
rear
panel
Again,
under
normal
usage,
these
controls
should
be
operated
near
the
0
dB
range
to
allow
optimum
performance.
The
unique
circuitry
of
the
701R
Mixer
derives
a
signal
which
is
the
sum
of
the
A
and
B
outputs
in
order
to
make
possible
operation
of
the
A
and
B
outputs
as
submasters
to
the
sum.
As
with
the
sub
A
and
B
controls,
the
sum
should
be
operated
close
to
its
middle
(0
dB)
range.
MASTER
MONITOR
CONTROL
(11)
The
master
monitor
control
is
located
just
above
the
sum
master
control.
Operation
of
this
control
is
similar
to
that
of
any
rotary
gain
control
on
the
mixer
and
should
be
set
in
con¬
junction
with
the
respective
individual
channel
monitor
send
controls
to
achieve
operation
somewhere
within
the
middle
rotation
of
the
master
control.
The
action
of
this
control
is
con¬
ventional
and
should
present
no
problem.
The
output
signal
from
the
master
monitor
is
available
from
the
output
connec¬
tors
on
the
rear
panel.
Again,
under
normal
usage,
these
con¬
trols
should
also
be
operated
near
the
center
of
their
range
to
allow
optimum
performance.
EFFECTS
RETURN
CONTROL
(12)
The
effects
return
control
may
be
considered
an
auxiliary
in¬
put
channel
with
a
high
impedance
input
and
has
been
designed
to
accept
a
wide
range
of
audio
signals.
This
ef¬
fects
control
is
coupled
to
the
effects
pan,
which
then
feeds
into
the
Sub
A
and
Sub
B
mixing
busses.
EFFECTS
PAN
CONTROL
(13)
The
effects
pan
control
determines
the
relative
balance
from
the
effects
level
control
blended
into
the
sub
mixing
busses.
EFFECTS
TO
MONITOR
CONTROL
(14)
The
effects
to
monitor
control
enables
signals
from
the
effects
return
input
to
be
mixed
back
into
the
monitor
mixing
bus.
This
unique
feature
enables
external
effects
such
as
echo
units,
flangers,
delay
lines,
etc.,
to
be
blended
back
into
the
monitor
output
signal
if
desired.
REVERB
RETURN
CONTROL
(15)
The
reverb
return
control
determines
the
amount
of
delay
(reverb)
signal
blended
back
into
the
subs.
REVERB
PAN
(16)
The
reverb
pan
control
determines
the
relative
balance
from
the
reverb
level
control
blended
into
the
sub
mixing
busses.
REVERB
TO
MONITOR
CONTROL
(17)
This
unique
circuit
of
the
701R
Mixer
allows
mixing
of
reverberation
signal
back
into
the
monitor
mixing
bus
for
those
who
do
not
prefer
a
“dry”
monitor
sound.
(NOTE:
Feedback
may
be
more
pronounced
with
reverb
on
the
monitors.)
EFFECTS
MASTER
CONTROL
(18)
The
effects
master
control
is
the
final
control
element
deter¬
mining
the
output
level
from
the
effects
send
jack
on
the
rear
panel,
as
well
as
the
amount
of
reverb
drive
delivered
to
the
internal
reverberation
system.
Please
note
that
no
reverbera¬
tion
effect
may
be
achieved
unless
the
individual
channel
ef¬
fects
send
controls
and
the
effects
level
control
are
adjusted
properly.
STEREO

LED
OUTPUT
LEVEL
INDICATION
(20)
NOTE:
The
two,
10-segment
LED
ladders
on
the
front
panel
are
extremely
important
visual
“tools”
and
their
operation
must
be
understood
to
achieve
maximum
benefits
from
this
mixing
system.
The
two
LED
displays
have
a
unique
“switching”
system
allowing
each
ladder
a
“dual”
function.
The
switch
located
to
the
left
of
the
LED
lad¬
ders
enables
the
operator
to
choose
either
the
Sum
(switch
in
the
“in”
position)
or
sub
A
(switch
in
the
“out”
position)
output
levels
to
be
displayed
on
the
left
LED
ladder.
The
switch
to
the
right
of
the
LED
ladder
allows
a
choice
of
Monitor
(switch
in
the
“in”
position)
or
sub
B
(switch
in
the
“out”
posi¬
tion)
output
levels
on
the
right
LED
ladder.
The
LED
ladders
feature
an
extremely
effective
“warning
system”
for
all
of
the
above
mentioned
functions.
Should
the
LED
ladders
reach
the
6
dBV
LED
(top
of
the
ladder
reading),
the
remaining
LEDs
automatically
“shut-down”
giving
the
operator
an
instant
visual
indication
that
the
possibility
of
clip¬
ping
might
be
present.
NOTE:
Under
normal
operating
con¬
ditions,
the
channel
levels
and
master
controls
for
Sub
A,
Sub
B,
Sum,
and
Monitor
should
all
be
operated
near
their
center
positions
(0
dB
indicated).
This
type
of
opera¬
tion
will
ensure
that
the
possibility
of
clipping
(overload)
is
at
a
minimum.
Each
channel
of
the
701R
Mixer
has
a
10
dB
LED
level
in¬
dicator.
This
red
LED
serves
as
a
warning
device
for
the
operator
indicating
that
any
particular
channel
has
reached
10
dBV
(3V
RMS),
and
the
possibility
of
“clipping”
could
occur.
Actual
“clipping"
occurs
at
18
dBV,
so
when
the
LED
flashes,
8
dB
of
headroom
is
left.
If
this
LED
stays
lit
con¬
tinuously,
the
operator
should
reduce
the
input
gain
control
on
that
channel.
Occasional
flashing
on
“peaks"
can
be
con¬
sidered
normal.
POWER
SWITCH/PILOT
LED
(21)
The
power
switch
is
of
the
simple
2-position
“rocker”
type
with
the
pilot
LED
immediately
below
it.
Operation
of
this
switch
is
conventional
and
should
present
no
problems
in
operation.
The
“on”
position
will
be
indicated
when
the
LED
pilot
light
glows,
signifying
power
is
being
delivered
to
the
mix¬
er
circuitry.
REAR
PANEL
INPUT
SECTION
The
rear
panel
of
the
701R
Mixer
contains
all
the
interface
connection
to
and
from
the
electronic
circuitry.
The
versatili¬
ty
offered
by
these
connections
is
unmatched
by
any
com¬
peting
unit
and
a
thorough
understanding
of
the
various
features
is
essential
in
order
to
fully
realize
the
performance
and
versatility
of
this
unit.
Each
channel
features
both
balanced
(symmetrical)
low
im¬
pedance
(600
ohms)
as
well
as
high
impedance
(50K
ohms)
unbalanced
inputs,
Each
of
these
inputs
feature
extremely
wide
dynamic
range
and
are
fully
transient-protected
to
en¬
sure
durability
under
road
conditions.
While
these
inputs
are
intended
primarily
for
microphones,
they
will
also
work
well
for
many
other
types
of
program
sources.
OUT/IN
JACK
(22)
The
701R
features
a
“stereo”
out/in
jack
on
each
channel
to
facilitate
the
use
of
direct
outputs/inputs
from
the
preamps
for
“patching”
various
auxiliary
units
(chorus,
flanging,
tape/digital/analog
delays,
equalizers,
etc.)
“inline.”
To
utilize
this
unique
system,
a
stereo
plug
(ring/tip/sleeve)
to
a
“Y”
chord
must
be
used.
The
“tip”
portion
of
the
W'
stereo
jack
serves
as
the
channel
send
(output)
while
the
“ring”
portion
will
return
the
processed
signal
to
the
channel.
The
“sleeve”
portion
serves
as
the
ground.
Since
this
is
a
stereo
jack
configuration,
the
first
“click”
on
the
jack
may
be
used
as
a
“pre-EQ”
output
with
a
mono
Vi"
plug
if
desired.
This
first
“click”
will
not
disturb
the
signal
flow
to
the
remainder
of
the
channel
as
it
is
fed
into
the
master
section.
NOTE:
IF
THE
SECOND
CLICK
OF
THE
OUT/IN
JACK
IS
UTILIZED
WITHOUT
RETURNING
ANY
SIGNAL
TO
THE
CHANNEL
FROM
AN
EFFECTS
DEVICE
THE
REMAIN¬
ING
PREAMP
FUNCTIONS
WILL
BE
DISABLED.

OUTPUTS
(23)
Each
line
out
features
a
phone
jack
as
well
as
a
balanced
XLR
output
to
enable
maximum
patching
flexibility.
These
line
amplifiers
are
capable
of
providing
more
than
8V
RMS
out¬
put,
and
are
fully
transient
and
short
circuit
protected
for
max¬
imum
field
reliability.
The
output
level
presented
by
these
jacks
is
controlled
by
the
settings
of
the
various
master
level
con¬
trols
on
the
front
panel.
EFFECTS
OUTPUT
(24)
The
effects
output
presents
the
signal
from
the
effects
mix¬
ing
bus.
This
jack
is
of
a
unique
“two-position”
type
with
the
first
position
being
the
low
level
output
and
the
second
posi¬
tion
being
the
high
level
output.
This
unique
arrangement
enables
use
of
this
mixer
with
either
line
level
or
instrument
level
effects
device
depending
on
which
“click”
of
the
jack
is
used.
The
overall
output
level
from
the
effects
jack
is
deter¬
mined
by
the
setting
of
the
master
effects
level
control
on
the
front
panel.
REVERB
FOOTSWITCH
(25)
To
facilitate
remote
control
of
the
reverberation
function,
we
have
included
a
remote
control
footswitch
jack.
Any
standard,
single
pole
footswitch
may
be
used
to
remotely
defeat
the
reverb
function.
Please
note
that
this
switch
disables
the
reverb
system
only
and
has
no
effect
whatsoever
on
the
ef¬
fects
system.
EFFECTS
RETURN
(26)
The
effects
return
input
on
the
rear
panel
may
be
considered
an
auxiliary
channel
featuring
its
own
level
and
panning
con¬
trols
located
on
the
front
panel.
This
effects
return
is
capable
of
handling
a
wide
range
of
input
signals
and
is
a
very
high
impedance
type
(220K
ohms).
The
effects
return
system
feeds
into
both
main
mixing
busses
and
is
intended
for
use
when
returning
signals
from
external
devices
to
be
mixed
into
the
main
mixing
busses.
STEREO
OUT
JACK
(27)
The
701R
Mixer
is
supplied
with
a
highly
usable
stereo
out¬
put
jack
for
connection
to
recording
decks
or
other
outboard
equipment.
Musicians/sound
personnel
will
find
this
line-level
stereo
output
perfect
for
recording
live
performances
and/or
rehearsals.
AUXILIARY
INPUTS
(28)
The
auxiliary
inputs
are
line
level
access
points
to
the
five
internal
mixing
busses.
They
are
medium
impedance
type
(33K
ohms)
and
are
provided
to
allow
parallel
mixers
or
for
any
other
purpose
that
requires
direct
signal
injection
into
the
internal
mixing
busses.

(30)
Channels
six
and

function
normally
with
microphones
or

but
also
have
additional

The
“in”

of
the
push

which
is
located
in
the

allows
an

at
the
