Series 2000
The DSR series 2000
consoleis the right
tool for the serious recording
engineer,
Thanks to its incredible
combination
of tried and tested circuitry
and the latest advances in technology
the 2000
series is superior to any other
console,in its price range,on the market.
Thousands of satisfied customers can
vouch for the fact that our in-line
mixing desk design is the best
available.lt combinesthe advantagesof a
compact P.A. desk with all the facilities
necessary for professional multitrack
recording.
The superb lay-out between
the channel input and the monitoring
output makes the confusion,often arising
from other in-line systems,athing of the
past.Novel high frequency stabilizing
techniques employed in conjunction with
extremely fast op-amps give the 2000
an
excellenttransparancy.
After eleven years in the business
DgR know how to produce the best
mixing desks and many innovations are
featured in our new and amazing 2000
model.Thanks to a new and unique
design costly routing switches and all
the additional wiring they entail are
now, with the 2000,rendered
obsolete
by
the introduction of the "Floating
Subgroup System'r.
It makes possible to create a subgroup
where necessary without the use of
patch leads.
It goes without saying that only
components of the highest quality have
been used throughout the manufacture
the desk.
This includes the use
self-cleaning fork- contact switches
rof
of
and
op-amps in sockets for easy
replacement.
The design incorporates a
minimum audiopath which contributes to
the 2000's excellent transparancy and
minimal crosstalk and control
interaction.Thanks to the superb printed
circuit board lay-out, stability and
signal to noise ratios are of the first
order.A separate lgrrrackmounting
power
supply is alsoa feature of the 2000.
CHANNEL
FEATURES.
The led bar is a 6 segment peak reading
bargraph display following the signal
coming into the monitoring section.Below
the ledbar section are the input circuit
controls and switches such as -20d8 pad
on the balanced mic input,a tine switch
and the remix switch.The gain control
acts on the discrete mic amp as a
negative feedback control and in the
line/remix mode as an input
attenuator.The mic aain ranges from
-20d8 to -64 dB whilst providing an
enormeous headroom with a minimumof
40
dB.

EQUALI
ZER
The 6@'iiFi-s one of the most musically pleasing
equalizers we have designed.After thoroughly listening
to the needs of engineers we have created a non
interacting range of control knobs which smoothly
adjusts the whole audio range to your own taste. To
compare original with equalized signals we have added
an equalizer onloff switch.
AUX SENDS
The ?0'0'0'Eifts offers 4 aux sends to allow for the
most extensive remix sessions.
They are all pre/post
switchable between channel and monitoring sections.
SUB GROUPING
Subgr-@ing-ETe 2000 console is done in a new way
and demands a new way of thinking.The basic idea is
to have subgroups only where you need them. We have
called it the "Floating Subgroup System" (F.S.S. ).
The 2000 console has 4 "F.S.S. " op-amps. In every
channel there are 4 sub switches.With the "to sub'r
switches you bring the signal into the subgroups and
with the 'rfrom sub" switches you take the signals out
of the subgroups.This can be done in every in/output
channel in the console.As an example:To place channel
l-8 on track l-2. Activate "to sub l/2" in channel l-8
and activate I' from sub 1
l2n in channel 1-2. By
activating other rrfrom sub l/2" switches you can place
the chan.l-8 signals anywhere you want them.lt is
possible in any size of console to connect any input
signal to any fixed multitrack input without patching
by using the "Floating
Subgroup Systemr'(F.S.S.).
The panpot with a -4.5 dB centre attenuation for
perfect stereo panning pans the signal between the
odd ancl even subgroups as well as the left/right
master buss, if selected. The 100 mm channel fader
with its auto p.f.l. and mute functions completes the
channel controls.
MONITORING
The m-6frilI6ffiffi3 already stated, is optically isolated
from the rest of the channel . The 58 mm monitoring
fader and its associated pan- pot are used to control 3
signal sources, the channel output,the tape
output( sync) and the effect input. An auto p. f.
|
.
switch completes the light coloured monitoring section.
On the back of the console there are the mic/line
XLR inputs,the tape sends and returns (which are
- l0dBV on the tip and +tldBu on the ring of the
jacks). The channel and monitor inserts and the effect
input which can be used as a line level input in the
remix mode.

MASTER
SECTION
The 6ii6iliiF9 ffii6Es from above to below the use and function of the master
controls First there are the l3 segment peak reading led bars displaying the
monitored signal.Then there is the central phantome switch providing 48 volt
powering for capacitor microphones. The oscillator is of the phase ihift type which
produces a low distortion 1 kHz sine wave on all the bussbs,when switched on.
The talk- back level brings the signal to auxl and 2 for communication purposes
when the talk- back switch above the faders is activated.At the same time the
monitoring is attenuated by 20
dB.

The 4 aux masters with their a.f.l. switches control the total outgoing level of
the aux sends. C.R.M. stands for control room monitor and regulates tlie leael of all
the signals going to studio monitoring equipment. With the stereo switch the choice
of input to the desk' s master section is made,either the master machine or the
master mixdown. C.,R.M. 1 and 2 give the choice of either one of the two monitoring
systems. This configuration has many possibilities, you can select either of tfre
monitoring loudspeakers or use the switches as mon-itor mutes. The mono switch
makes comparison between stereo and mono possible.The p.f.l.la.f .1. led indicates
whether p.f.l.la.f .1. switches anywhere in the console
have been activated. The 100
mm left/right faders complete the master section of the console.
