FEATURE OVERVIEW
AUTHENTIC CIRCUIT EMULATION
Our real time SPICE type component-based circuit si-
mulation approach allows us to authentically capture
the sound and feel of the original analog unit with all
its nuances. Every crucial part of the device, including
in- and output transformers, sidechain and audio
path tube stages, the emphasis filter network, and the
T4A cell have been faithfully modeled to its original
60s reference unit.
SIDECHAIN (NEW)
This feature allows you to control the gain reduction
on your main signal via the envelope of the external
sidechain signal.
CELL SELECTOR (NEW)
Use this feature to choose from 3 different opto-
electric cells (A, B, and C). Each one offers different
attack and release times.
EMPHASIS CONTROL (NEW)
The Emphasis control feature is responsible for
controlling the sidechain pre-emphasis. It is useful for
keeping high frequencies in check, preventing
overmodulation and allowing for a higher sensitivity
to high frequencies.
MAKEUP GAIN (NEW)
Use this feature to optimize your output signal, by
trimming it with the all new make up gain control.
MIX (NEW)
You can now mix in the compressed signal with the
original one for maximum control.
SSE2 OPTIMIZED CODE
DSP operations are pipelined using the SSE2 instruc-
tion set. This ensures the highest possible
performance operation despite very complex compu-
tations.
AUTO-ADJUSTED OVERSAMPLING FOR MAXIMUM
AUDIO TRANSPARENCY
Aliasing artifacts are efficiently attenuated using a low
latency linear phase Dolph-Chebyshev poly-phase de-
sign. The oversampling is auto adjusted to your ses-
sion‘s sample rate to save
valuable CPU power while offering the most transpar-
ent sound possible.
HIGHDPI / RETINA SUPPORT
All our plug-Ins support high pixel density on Mac OSX
and Windows to bring you the most enjoyable user
experience on high DPI displays. Please refer to your
manual to find whether your DAW is HighDPI capable
if you‘re working on Windows.
