High Band Limiter
See description of settings for Low Band Limiter
Bass Clipper
The Bass Clipper operates between the output of the Low Band Limiter and the Low Band Mixer, the output of
which feeds the Final Limiter. Its purpose is to keep excessive bass out of the Final Limiter, reducing IM
(intermodulation) distortion while keeping and even enhancing the bass punch of the program material. There are
two different Bass Clipper styles available. (Described below.)
Clip Drv (Bass Clipper Drive)
Adjusts the drive level to the Bass Clipper over a range of +/- 6 dB. Higher settings will increase
the amount of Bass Clipping, increasing bass density while keeping the actual peak bass level fed
to the Mixer the same This allows you to reduce the Low Band Mixer control to reduce IM
distortion in the Final Limiter without reducing the amount of perceived bass in the program
material. Be careful! Too much clipping by the Bass Clipper can soften bass 'punch'. It may also
be heard as a “rattling” sound in the bass or cause additional artifacts in the codec following the
Omnia.ONE Multicast.
Girth Clip
When “ON”, this Bass Clipper style is designed to create a phatter effect to low frequencies, and it
will help create the illusion of more bass on smaller speakers. Also, this algorithm, which is
mathematically derived, will contribute lower midrange IMD components to the spectrum. So live
voice, vocals and solo instruments that are present along with strong bass in the program material
will sound cleaner, yet will still create an in-your-face effect to the low end.
When both the Girth Clip and Tight Clip settings are both set to “OFF”, the Bass Clipper is
effectively bypassed. Both algorithms can be “ON” at the same time but this is not recommended.
Tight Clip
When “ON”, this Bass Clipper style is a straightforward hard limiter that will create a deep, sub-
harmonic effect to the audio. The drawback is that it can generate intermodulation distortion in the
Final Limiter and increase artifacts in the codec employed after the Omnia.ONE Multicast.
When both the Girth Clip and Tight Clip settings are both set to “OFF”, the Bass Clipper is
effectively bypassed. Both algorithms can be “ON” at the same time but this is not recommended.
Filtering
Adjusts the amount of time-aligned low-pass filtering after the Bass Clipper. Normally this extra
filtering is not needed but if heavy amounts of Bass Clipping are being used, especially when
using the “Tight” Bass Clipper style, the filtering can help reduce distortion or artifacts and can
provide a “rounder” and smoother bass sound.

Mixer
Low Band
Adjusts the output level of the low band limiter into the following Final Limiter stage. Higher
numbers result in more low frequencies (bass) but too much mix level can make the following
final limiter work unnecessarily hard.
