The D

& R

mixers have

been developed

in

close

cooperation with

several

leading

popgroups

and

stu-

dios in

Europe.

Some outstanding facts

are

the

conveniently arranged control

panel,

with

just

those

possibilities

you

need, the handable

size and solidity, essential for

groups

on

the

road,

and the highly

competetive

price.

Not

mentioning here

the

outstanding

performance

characteristics,

which

makes this

mixer a fine

studio

console.

All

mixers can be delivered with high impedance line inputs

(C-version),

or low impedance

balanced

microphone inputs

(Cl-version),

the

last

using

Beyer

Dynamic microphone transformers,

providing

a

200

Ohms balanced

input;

all

inputs and

outputs

are

terminated on the

rear

panel

at 3

pole

jack

sock-

ets. The

Cl-version also

having a multipole connector,

enabling the use

of

a remote control

cable,

in-

corporating

the

balanced input lines, as well as

the

master

output

and fold back

output

lines. In use

with

popgroups,

you

now can

make

a

good

balance

of the several

instruments

sitting

with

your

mixer

in

the

audience,

which is

almost

impossible

on

stage;

in

the studio the

remote control cable

will

link

your

recording

room

with the control

room.

All

input

channels

are

provided

with

pre-set

volume control,

to

eliminate

overload, three

very efficient

equalizers,

pre-fader

echo-send

control,

pan-pot,

pre-fader

fold back

volume for monitoring on stage

or

through headphones

in

the studio,

cue

press-buttons

with color-indication

for control of the

pre-fader

input level

on

the

V.U.

meters

and through the

phones

and

last but not least high

quality

70 mm.

Pr6h

faders

for linear attenuation of

the

channel

output.

Different color-indications on the

control-knobs

are

provided

for convenient discrimination

of

the several functions.

f

nput

channel12

(or

18) can be

used as

echo-return

channel,

giving

it the same

possibilities

as a

normal

input

channel.

The

echo-send

control

will automaticaly

work as Spin,

which re-injects

a controlled a-

mount

of echo-return

into the echo-send

for reverberation.

A simple three

heads tape-recorder

will now

work as

a

good

echo-unit

without any changes.

The two

master output

groups

are

provided

with

Pr6h

70

mm.

faders for

left

and right volume

attenuation

seperately,

and

a stereo

rotary

pre-set

for both channels

isalso

provided.

The fold back

line has

a mas-

ter

volume. Cues

for the

master outputs

in stereo

and

the

fold back output are

provided.

Break

jacks

are

incorporated on

the two master output

groups

and

connection

is

by

means

of 3

pole

jacks.

High

quality

V.U. meters

are used.

For

internal

communication

provisions

have

been made. On

the

desk

is a microphone

input situated,

which

can be mixed

into the fold

back line by

way of a color-indicated

push-button.

In this way

the

tech-

nician

can talk to the stage

or recording

room

without interupting

the live

sound or

the recording.

The mixer can

be altered

very

easily, for instance

when

using a

remote

control

cable,

you

can alter

the

inputs

on the back

of the

mixer

in

just

a few

hours into

break-jacks,

thus obtaining insertion

points per

input channel,

giving

the

possibility

to

use

per

channelanequalizer,

compressor-limiter, etc.

Each

input

can

be altered

in a

few minutes

to low or high

impedance inputs. Block-diagram and electrical

circuit

are

delivered

with every mixer.

Of course

we can do every change and

repair

ourself,

but having all

technical

data and

the service-friendly

framework

will

give

you

extra security, so

you

can

perform

no

matter

l,Yhatever happens.
