AM MENU
Final Menu
The
Final
menu is home to the controls that are most influential in setting overall loudness and determining the
tradeoff between loudness and quality.
The
Bass Compression Threshold
control sets the threshold of the Wideband AGC 1 compressor when it is used
in “Bass Only” mode (otherwise it will be grayed-out). Lower settings will allow more bass compression to be
handled in this section rather than by the bass clipper further along in the chain.
The
Bass Clip Threshold
control sets the threshold of the Bass Clipper. Lowering the threshold (moving the slider
to the left) increases the amount of bass clipping and protects against intermodulation distortion at the expense of
bass punch.
Conversely, raising the threshold (moving the slider to the right) will yield less bass clipping which in turn moves
more of the work load to the final clipper. This will result in a punchier bass sound but at the risk of creating
increased intermodulation distortion.
The
Final Clip Drive
control sets the drive of the final clipper. Decreasing the drive (moving the slider to the left)
reduces the amount of clipping. Conversely, increasing the drive (moving the slider to the right) will result in
more clipping.
Less clipping will result in a more open, less-processed, cleaner sound, but at the expense of overall loudness. More
clipping can result in a louder on-air sound – but only up to a point. Even if total dial domination and loudness are
your processing goals, there comes a point when the final wave-form is completely full and increasing the amount
of clipping will no longer yield additional loudness – only more distortion.
We strongly recommend using Omnia.7’s oscilloscope as well as your ears to monitor the MPX Output signal while
adjusting the final clip drive. The fact that this control is calibrated in one-quarter dB increments should give you
the (correct) impression that small changes make a big difference in the sound. Keep in mind that a setting of
+0.00 simply means that the control is at the middle of its range and does not necessarily mean that no clipping is
taking place.
Bypass Menu
Enabling the
Bypass Processing
button bypasses all dynamics processing except for Undo, which has its own
dedicated controls in the
Undo
menu. The
Bypass Gain
control should be set to that the level of unprocessed
(bypassed) audio matches the level of processed audio as closely as possible.
