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

OUT

(19)

Controls

the

level

appearing

at

the

stereo

output

jack

at

the

rear

panel.

(See

back

panel)

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.

LINE
