MixDream XP - 16-in-2 analog mixer in a 19-inch/1U format, SPL
The MixDream is a cascadable, 16-in-2 analog mixer in a 19"/1U format. Any DAW or digital console can be expanded with high-grade analog stereo summing functionality.
MixDream Advantages- An Overview
- Active analog summing on just 1U rack space - no analog mixing console
- Sophisticated, active Class A/6oV stages for analog summing in the quality of the best consoles
- All analog tracks can be summed before A/D conversion.
- Channel adjustments and automation (level, panorama etc.) remain controlled from the
DAW so the user loses no digital efficiency
- Lower DAW processor utilization rates
- Latency free monitoring
- Surround capable (from up to 3 MixDreamXP units)
- Channel capacity expandable through linked units
- Proprietary differential amplifiers for each input
design plan provides for stereo mixdown at the analog level. This concept offers
high-grade analog summing without panorama and fader controls, in turn allowing
an engineer to retain the entire scope of his computer automation. In use, the
MixDreamXP requires almost no departures from an engineer's usual working mode,
so that all his trusted DAW features and familiar working routines remain
available while the MixDreamXP seamlessly expands his aural mixing
One MixDreamXP can
sum up to 16 audio tracks to a stereo signal, and should the need arise for more
than 16 tracks, several MixDreamXP may be linked together. Owners of a MixDream,
model 2384, can expand this unit with the cost effective MixDreamXP at an
identical quality level and by the way, that's where the suffix "XP" comes from
discrete class A technology is based on the same 60-volt rails (+/- 30V) of the
MixDream model 2384. Newly developed circuitry, based on the most modern analog
components, guarantees an extremely high slew rate, a very low noise level of
-97dBu and a dynamic range of 125dB. Thus the MixDreamXP easily reaches the
technical level of the best analog consoles.
Nowadays, many are asking whether analog summing is
better than digital summing. But perhaps the real question is whether digital
summing better than analog summing? We at SPL don't know of anyone who says so.
We do know that summing with the MixDreamXP creates an amazing signal depth,
precise localization and a wonderful stereo imaging. Moreover, the addition of
individual instruments results in soft and pleasant transitions.
These are analog
summing results that we appreciate from past decades of the best analog
technology. The MixDreamXP now allows DAW users to exploit this potential with
maximum comfort and uncompromising quality, ensuring that nothing can stand in
the way of the engineer's having the best of both analog and digital
Sampler, Keyboards etc.
Along with DAW audio tracks and effects machines
or processors in the insert loops, samplers, keyboards and expanders may also be
connected directly to the MixDreamXP. Then the Midi tracks need only be added in
the DAW project, the outputs (for example, from a keyboard) are then routed
directly to the MixDreamXP.
To save converter channels, all channels may be switched to Mono
so that two signals can be converted by a paired D/A.
In this case such
signals are characteristically chosen which would receive a more central
placement in the stereo mix (e.g. kick, snare, lead vocal, bass). All channel
pairs must otherwise be panned hard left/right in the mix.
Tracks destined for analog summing are routed from the
DAW to the MixDreamXP via A/D converters. Identical converters are ideal to
exclude level and sound differences.
Although you may
often wish to sum more than 16 tracks, a general recommendation to reduce track
numbers is to route those tracks to a common output bus of the sequencing
program which are not played back simultaneously in your arrangement. This way
you avoid digital summing and your production benefits from the full potential
of 100% analog summing.
With mono signals
one should switch these to mono mode to confine them to single D/A converter,
thereby avoiding the waste of having to use a D/A pair for one mono track. In
the DAW such signals must be panned hard left or right.
To reduce track numbers, there are two other options besides
the above mentioned "Summing" tip:
Well, you could buy additional MixDreamXP
(which we confess would make us happy-and we're sure would not disappoint you)
or sum your grouped tracks with the MixDreamXP itself.
For example, if
you've done a chorus backup in 16 solo tracks, you can adjust your panning in
the DAW and the MixDreamXP sums a stereo mix which is recorded again-the sound
benefits of analog summing are larger than the disadvantage of a further A/D-D/A
Your MixDreamXP is predestined for mastering
applications, as we've planned its superior sound quality for just such
are especially interesting: discrete Mastering, and upsampling to SACD/DVD-A
formats. Normally a studio mastering engineer requires that a stereo file be
made available for his or her work. But in such a mixdown, any problems (for
example, significant variations in volume among instrumental subgroups) will
mean equally significant limitations to your final mastering options. Instead,
however, if one masters from a discrete mix with single tracks or subgroups,
each of these can be adjusted just as easily and quickly in the mastering
process-to the extent that even individual groups can be tweaked with different
processing. Your final result is clearly better and the time needed,
minimal-especially since it is less likely that a new mix will be called
sessions can be summed in the infinite resolution of analog signal processing
equipment, something that may also be of special importance when an engineer
wishes to upsample to SACD or DVD-A.
An expansion connector provides for a second MixDreamXP input
should 16 channels not suffice. The Main Outputs of the second MixDreamXP must
be connected to the Expansion Inputs of the first unit; do not connect both
If more than three
MixDreamXP are to be summed, we recommend to employ a further MixDreamXP as
master-otherwise the signals from the first MixDreamXP (to cite a "worst case
scenario") would unnecessarily be summed in each following unit.
In such a
chain One MixDreamXP is connected to the Expansion Inputs while all other units
are connected to the usual (DB25) Input Channels.
