| The DMC completes
the range of SPL 120V mastering consoles. Housed in a 19"/5U rack mount chassis
the DMC features the same unique 120 volts rails like the MMC1 and MMC2
multi-channel consoles to achieve the optimum audio performance.
Conceived as the
center of a mastering environment, the DMC provides speaker management, sources
and returns connectivity, input and output trimming, pure analog 2-channel
master fader and monitor level setting.
As an option, the DMC can be supplemented with the SPL
MasterBay to provide an automated 8 x 2 channel insert routing of external
processors.
Our aim in the
development of 120V mastering equipment was the creation of a technology that
would be superior in audio quality to all known and foreseeable audio formats,
whether analog or digital. Such a console would provide both for an unaltered
reproduction of the sonic quality of SACD and DVD-Audio and in the process,
remain a safe capital investment for many years.
Digital audio
formats have undergone continuous development and change and will continue to do
so. The degree of incompatibility created by the "format war" between PCM and
DSD is a main argument for a technology that is superior in dynamic range,
headroom and sound quality to either or any other such format � and that is
discrete analogue technology in its most advanced implementation.
Moreover additional
aspects speak for the employment of high-performance analog
technology:
The number of
necessary AD/DA conversions should be reduced to a minimum. With the DMC,
digital sources can be connected to a digital router, which outputs the selected
source through the preferred DA converter. This ensures that the sound quality
remains comparable and is not affected by converter differences.
From a purely
aesthetic standpoint, high quality analog outboard processing consistently
proves itself superior to digital processing. The analog concept allows for
problem-free integration of such analog processors.
Monitors and power
amplifiers are almost exclusively analog in design. Yet another converter at
this point in the chain only degrades monitoring signal paths. Furthermore, DSD
signals cannot be monitored on a digital monitoring that operates in
PCM.
New Analog Technology
SPLぴけねぜ SUPRA operation
amplifiers are used throughout. They perform at an industry benchmark of 120
volt. The SUPRA op amp achieves a signal-to-noise ratio of 116dB with a headroom
of 34dB. The dynamic range amounts to 150dB with a frequency bandwidth of
200kHz.
With such specifications, the DMC rides comfortably beyond the
requirements of either the current maximum 24Bit/192kHz PCM format or 1Bit/256
fs DSD format.
DMC configuration
Sources
The Sources section provides for the selection of four stereo inputs and
four returns. The inputs are fed to the mastering path, the returns are fed to
the monitoring section.
The Source section is divided into two parts. At the
left are the input selectors, which are fed to the mastering path. The DMC
accepts four stereo inputs here. The returns provide selection options for
returns from recorders, DAW, audio players, and so on.
All Input buttons
allow for switching between the input monitoring mode and the output monitoring
mode for a direct comparison what comes in and what goes out of the
console.
Input
Any
input selected in the Source section is routed to the Input section. The signal
passes passive L/R Phase Reverse switches, balanced input receivers and active
L/R On as well as Mono L/R switches.
Pre and Post
Insert Trims
Sophisticated rotary trim switches with 32 steps are used
for precise gaining from -10dB to +10dB for each Pre Insert L/R as well as Post
Insert L/R channel. These switches route the signal through one precision
resistor at any position only, keeping thermal noise and tolerance at an
unrivalled minimum.
Insert
The DMC offers a switchable Insert point between the Pre
Insert Trims and the Post Insert Trims to include external processors into the
signal path.
Monitor
Section
Besides the central high-end Monitor Level control the DMCぴけねぜ
monitor section features L/R Solo switches as well as L/R Phase Reverse and L/R
Mono switches. Three signal paths can be monitored: input, output and return.
Master
Fader
This fader features the same level control potentiometer as in the
Monitor Level section for dynamic mastering purposes and fine tuning the overall
level from +10dB to -80dB. The range can also be customized to operate from 0dB
to -80dB.
The Master Fader allows for dynamic mastering as well as fine
tuning the overall level from +10dB to -80dB. With this control's extremely high
(if not infinite) resolution the engineer can attain every ounce of recording
headroom. The result is an unparalleled excellence in dynamic mastering. The
Master Fader can be taken out of the signal path with the Master Fader On
switch.
Speakers
The Speakers section allows for connection of four
stereo speaker sets. Three different Dim levels (-10dB, -20dB and -30dB) and
Mute can be selected by the push of a button.
Option: SPL
MasterBay
The DMC can optionally be complemented with an insert box
called MasterBay. The MasterBay consists of a 4U
insert box and a remote control panel. Up to eight, 2-channel processors can be
connected to the insert box, which is operated by the MasterBay remote panel.
The remote control provides a button for each of the eight external
processors. Depressing them in sequence switches among choices in processor
signal flow. Beside each button is a seven segment LED-display indicating the
current position of the processor in the sequence.
The mastering engineer can
use this feature to compare between sequences in a varying order or to compare
the same type of processors.
Three memory banks are
available which allow an active signal flow sequence to be compared instantly at
a button push with three others (for a total of four). If the optional MasterBay
is connected, the DMCぴけねぜ Insert On switch activates the MasterBay or switches it
to a hard-bypass.
