The

system

you

have

purchased

is

a

very

portable

package

with

the

flexibility

of

mixers

twice

the

size

at

twice

the

price.

The

601R™

features

six

channels,

excellent

3-band

equalization

and

rack

mount

versatility.

...

:Rack

mountable

mixers

have

a

special

place

in

sound

reinforcement

applications,

and

many

times

no

other

type

product

will

suffice.

The

601R™

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

The

input

gain

control

determines

the

sensitivity

of

each

individual

channel.

It

should

be

adjusted

accordingly

to

each

instrument

or

vocal

that

is

being

patched

into

this

system.

The

operator

must

adjust

the

input

gain

so

that

overload

“clipping”

is

avoided

at

the

input.

A

very

strong

signal

coming

into

the

mixer

would

require

a

fairly

low

setting

of

the

input

gain:control,

and

obviously,

a

very

weak

signal

will

require

a

fairly

high

setting

of

this

control.

Proper

adjustment

of

the

input

gain

control

may

be

easily

E

by

setting

up

the

highest

expected

input

signal

level

and

adjusting

the

input

gain

so

that

o

"clipping"

or

distortion

is

heard

from

the'amp/speaker

system.

After

this

mixer

has

been

used

several

tipica:

the

operator

will

have

a

very

good

idea

of

the

signal

levels

encountered

and

will

be

able

to

set

up

the

input

sensitivity

with

no

difficulty.

Please

be

aware

that

different

types

of

microphones

will

have

different

output

levels

and

different

performers

will

get

widely

varying

signals

from

microphones

depending

on

the

strength

of.their

voices

and/or

their

basic

microphone

technique.

MONITOR

SEND

CONTROL

The

monitor

send

control

is

the

channel

mixing

element

for

determining

the

all

important

monitor

mix.

The

signal

for

the

monitor

send

is

obtained

right

after

the

input

preamp

and

before

the

channel

EQ.

This

type

control

is

referred

to

as

a

pre-monitor

send,

i.e.

it

is

before

or

pre

to

the

channel

equalization

and

channel

level

control.

This

makes

the

control

independent

of

all

equalization

and

channel

level

adjustments.

Alterations

to

channel

EQ

will

not

affect

the

equalization

of

the

monitor

system.

Having

the

monitor

send

with

pre-capability

is

absolutely

vital

to

avoid

feedback

of

the

monitor

system

when

various

channel

adjustments

are

made

to

the

outfront

system.

HIGH

EQ

This

flat

“12:00”

position

is

an

excellent

placeto

begin

tuning

the

system.so

that

with

different

rooms

and

halls

you

will

be

to

determine

what

MID

FREQUENCY

EQ

CONTROL

The

mid

control

is

capable

of

15

dB

boost

or

cut

at

600

Hz

with

a

peak/notch

type

filter

response.

This

middle

EQ

circuit

enables

control

over

the

vital

mid-range

frequencies.

The

action

of

this

middle

filter

is

-.

somewhat

different

than

the

high

and

low

EQ

since

it

is

of

the

peaking

and

notching

type.

This

type

of

filter

response

is

necessary

to

avoid

undue

interaction

with

the

high

and

low

equalizers.

Caution

must

be

exercised

in

order.

to

avoid

overboosting

or

overcutting

the

mid-range.

Experience

has

proven

that

for

most

applications,

a

very

slight

mid-range

cut

tends

to

produce

a

tight

and

well

defined

sound.

Generally,

larger

amounts

of

mid-range

boost

are

extremely

unpleasant

and

will

probably

never

be

used

except

for

special

effects

or

to

correct

extremely

marginal

microphones

or

unusual

voice

timbre.

Most

systems

tend

to

get

"muddy"

and

lose

a

certain

amount

of

presence

when

excessive

arnounts

of

mid-

range

are

used.

More

feedback

problems

aré

usually

encountered

when

too

much

mid-range

boost

is

used

with

sound

reinforcement

systems.

LOW

FREQUENCY

EQ

CONTROL

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

sound

reinforcement

speaker

systems.

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

claiming

20

to

25

dB

boost

and

cut.

Care

should

be

taken

with

the

low

frequency

control

to

not

overboost

lows

on

any

particular

instrument

or

vocal

due

to

the

fact

that

tremendous

amounts

of

power

amp

"headroom"

will

be

used

up

and

a

general

"muddiness"

will

be

apparent

in

the

speaker

system.

Woofers

may

also

be

blown

much

more

easily

with

excessive

low

frequency

boost.

EFFECTS

SECTION

The

The

versatility

offered

by

these

is

unmatched

by

and

a

thorough

understanding

of

the

features

is

microphones,

they

wil!

also

work

well

for

many

other

types

of

OUT/IN

JACK

The

601R™

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"

cord

must

be

used.

The

tip

portion

of

the

1/4"

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

thejack

may

be

used

as

a"pre-EQ"

output

with

a

mono

1/4"

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

AUXILIARY

The

to

the

They

are

the

for

any

other

purpose

that

injection

into

the

internal

REVERB

FOOTSWITCH

To

facilitate

remote

we

have

included

a

jack.

Any

standard

single

footswitch

may

be

used

to

remotely

Please

note

that

this

only

and

has

no

effect

whatsoever

on

the

LINE

INPUTS

The

line

input

features

phono

and

allows

a

signal

to

be

patched

directly

into

the

"line

main"

and

"line

monitor"

controls

in

the

master

section.

These

line

inputs

are

extremely

useful

when

a

tape

deck

needs

to

be

patched

into

the

system

without

tying

up

a

desperately

needed

channel

input.

Please

note

that

RIAA

equalization

is

not

built

into

this

input.

Also

note

that

the

dual

phono

jacks

are

“bridged”

(parallel)

allowing

a

"stereo"

signal

to

be.patched

in.

Naturally,

the

"bridging"

reduces

this

signal

to

mono.
