AM MENU
Clipper Menu
The
Clipper Menu
provides control of the final clip drive, bass clipper slope, and bass clipper threshold.
♦
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. This control ranges from -6.0 to +6.0 in one-quarter dB
increments, which 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 means the control is at the middle of its range, but does
not necessarily mean that no clipping is taking place.
♦
The
LF Protection Threshold
controls frequencies between 0 and 1,500Hz, though audio in some of these
frequencies will already have been dealt with by the bass clippers.
♦
The
Bass Clipper Threshold
control sets the threshold of the Bass Clipper. Lowering the threshold (mov-
ing 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.
