DMix
DMix: Optimum Mobile
Platform Delivery
In just one engine, DMix can downmix, loudness
process and true-peak limit any mono, stereo
or 5.1 source. Input formats are dealt with auto-
matically without the need for metadata, down-
mix takes place at overload-proof 48 bit resolu-
tion, loudness processing complies with ATSC
or EBU standards, and transparent transcod-
ing keeps the output perfectly conditioned for
mobile TV, iPod or IPTV. Even a wide loudness
range feature film is transcoded automatically on
the fly at an impeccable audio quality.
DMix presets for ATSC and EBU standards may
be found in the new Down-conversion factory
preset bank. Be sure to try the new iX presets
featuring image enhancement for an extra envel-
oping experience when listening in headphones
BS.1770-2 based processing
New EBU R128 and ATSC A/85 compliant pro-
cessing algos and presets for mono, stereo, 5.1
and format conversion.
BS.1770-2 compliant metering
New LM6 loudness radar meter compliant with
EBU R128, ATSC A/85, TR-B32 and ITU-R
BS.1770-2. For legacy purposes, LM6 can also
be switched to the ungated, original BS.1770
measure of Program Loudness.
Loudness meters in MKII frames feature 24/7
logging capability without even seeing a com-
puter. Measurement and logging presets are
found in the new Metering factory preset bank.
More improvements
Version 3.20 includes various other enhance-
ments. To name a few: Centralized preset han-
dling, more SNMP functions, anti-aliased meter
graphics, new Metering, Down-conversion and
Up-conversion preset banks.

tual delay value.
Delay
Delay alignment of the Input channels. Depend-
ing on the selected configuration type, either one
common delay setting or individual delay set-
tings are available.
– Delay unit: “ms”: 0 to 4000 ms
– Delay unit: “Frames 24”: 0 to 96 Frames
– Delay unit: “Frames 25”: 0 to 100 Frames
– Delay unit: “Frames 30”: 0 to 120 Frames
Center Gain
Range: Off, -12.0 to 0.0 dB
Downmix gain for the Center input relative to
L and R front. Default Center gain would be
-3.0 dB, but DMix employs a high resolution
downmix structure with loudness, 5-band and
