The D & R mixershave
beendeveloped
in close cooperationwith several leading
popgroups
and stu-
diosin Europe.
Someoutstandingfactsarethe convenientlyarranged control panel, with just those
possibilities
you
need,thehandable
sizeandsolidity,essentialfor groups
on the road,
andthe highly
competetive
price.
Notmentioninghere
the outstanding
performance
characteristics,
whichmakesthis
mixer
afine
studio
console.
Allmixerscanbedeliveredwithhighimpedanceline inputs(C-version),
or low impedance
balanced
microphoneinputs
(Cl-version),
the last using
Beyer Dynamic microphone transformers,
providing a
200
Ohmsbalanced
input;
all inputsand outputs
areterminatedon the rearpanel
at 3 polejack sock-
ets.TheCl-versionalso havinga multipoleconnector,
enablingthe useof a remotecontrol cable,in-
corporating
the balancedinputlines,aswellasthemaster output and fold back output lines. In use
with
popgroups,
you nowcanmake
a goodbalance
of theseveral
instruments
sitting
with your mixerin
the
audience,
whichis
almost
impossible
on
stage;
inthestudiotheremotecontrolcable
willlink
your
recording
room
withthecontrol
room.
All input channels
areprovided
withpre-set volumecontrol,to eliminate
overload,three very efficient
equalizers,
pre-fader
echo-send
control,
pan-pot,

fold backvolumefor monitoringonstage
or
throughheadphones
inthestudio, cuepress-buttons
with color-indication
for control of the pre-fader
inputlevel
on
the
V.U.

andthroughthe
phones
and lastbut not leasthigh
quality
70mm.Pr6h
faders
for linearattenuationof the channel
output.
Differentcolor-indicationson the control-knobs
are
provided
for convenientdiscrimination
of the severalfunctions.
f
nput
channel12
(or
18)canbeusedas echo-return
channel,
giving
itthesame
possibilities
asa normal
inputchannel.
The echo-send controlwill automaticaly
work as Spin,
which re-injects
a controlleda-
mount
ofecho-return
intotheecho-send
for reverberation.
A simplethreeheadstape-recorder
will now
workas
agood echo-unit
withoutanychanges.
Thetwomasteroutput
groups
are
provided
with Pr6h 70
mm.
fadersfor left andrightvolume
attenuation
seperately,
and a stereo
rotary
pre-set
for both channels
isalsoprovided.
Thefoldbacklinehas
a mas-
tervolume.Cues
for the masteroutputs
in stereo
and the fold back output are provided.
Breakjacks
areincorporatedon thetwo masteroutput
groups
and connectionis by meansof 3 pole jacks. High
quality
V.U.meters
areused.
For
internal
communication
provisions
have
beenmade.On the desk is a microphone
inputsituated,
whichcanbe mixed
intothefold backlinebywayofa color-indicated
push-button.
Inthisway
thetech-
nician
cantalktothestage
orrecording
room
withoutinterupting
thelive
soundor
therecording.
The mixercan bealtered
very
easily,for instance
whenusinga remote
controlcable,
you can alter
the
inputs
on the back of the mixerinjust a few hoursintobreak-jacks,
thusobtaininginsertion
pointsper
inputchannel,
giving
the
possibility
to use
per
channelanequalizer,
compressor-limiter,etc.
Each
input
can
bealtered
inafewminutes
to lowor high
impedanceinputs.Block-diagramand electrical
circuit
are delivered
with everymixer.Of course we cando everychange and repairourself,
but havingall
technical
dataand
theservice-friendly
framework
will give you extra security,so you can perform no
matter
l,Yhateverhappens.
