control to 0. Thus, your settings automatically track any changes you make in the

two “click stops” slower than the setting of the

If your setting of a given

control would otherwise create a release
slower than “slow” or faster than “fast” (the two end-stops of the

control), the band in question will instead set its release time at the appro-
priate end-stop.
Band 1-5 MaxDeltGR
controls set the maximum permitted gain difference be-
tween the left and right channels for each band in the multiband limiter. The
1100V2 five-band processing chain uses a full dual-mono architecture, so the chan-
nels can be operated anywhere from fully coupled to independent. We recommend
operating band 1-4 fully coupled (

stability. However, audio-processing experts may want to experiment with lesser
amounts of coupling to achieve a wider, “fatter” stereo image at the cost of some
image instability.

most factory presets. This permits band 5 to be used as a
fast-operating high frequency limiter that works independently on the left and right
channels. This prevents gain reduction in one channel from causing audible spectral
modulation on the other channel. However, the additional stereo difference chan-
nel energy created by independent operation can adversely affect certain low bi-
trate codecs (like WMA). It is wise to do careful listening tests through the codec to
determine if it sounds better with

B1/B2 Crossover
(Band 1 to Band 2 Crossover Frequency) sets the crossover fre-
quency between bands 1 and 2 to either 100 Hz or 200 Hz. It significantly affects the
bass texture, and the best way to understand the differences between the two
crossover frequencies is to listen.
If the Host Computer Restarts or Crashes…
When you are using OPTIMOD-PC’s hardware inputs and outputs (that is, when
OPTIMOD-PC is emulating a stand-alone audio processor), OPTIMOD-PC is designed
to gracefully handle problems that occur in the host computer:
•
If the host computer is restarted in an orderly way (using Windows’ “restart”
command), OPTIMOD-PC will continue to process audio normally through its
hardware inputs and outputs with no gaps or interruptions. This allows you to
do normal Windows security updates without interrupting the audio even if the
updates require you to restart your computer.
•
If the host computer crashes, OPTIMOD-PC will usually continue to pass signal
normally through its hardware inputs and outputs because its processing is done
with onboard DSP, independent of the computer’s CPU or operating system.
When you finally reset the host computer to recover from the crash (via either a
