More TREBLE (HF)
We can obtain more high frequency energy in several ways. When processing for FM we need to use distortion
controlled clipping to preserve as much of the high frequency content as possible, which will be removed by the de-
emphasis curve in the listeners radios. The ‘HF CLIPPING’, band 4 'DRIVE' and ‘PEAK ATTACK’ controls governs
the amount of high frequency distortion controlled clipping that is performed.
Multi-band AGC:
Increase the drive to the AGC band 4.
Speed up the AGC band 4 release time, making it faster.
Lower the band 4 gate threshold, allowing more gain to be applied to low level HF waveforms.
Consider 'force gating' the AGC band 1 so the multi-band AGC for band 1 is bypassed.
Multi-band Limiters:
Increase the band 4 limiter drive.
Slow down the peak attack time for band 4, letting more through to the clippers.
Speed up the release time of the average release time constant of those bands
Slow down the band 4 average attack time so that the peak time constant dominates the control signal providing
faster control.
HF clipper:
Set the HF clipping control to higher numbers which shifts control from the limiters to the distortion controlled HF
clipper.
WE SUGGEST ONLY SMALL MODIFICATIONS FROM FACTORY PRESET SETTINGS IF YOU ARE
MODIFYING LOTS OF THE PARAMETERS. IF YOU ARE ADJUSTING ONLY A COUPLE FROM THE ABOVE
SUGGESTIONS THEN YOU PROBABLY HAVE A BIT MORE LEE-WAY. IT IS VERY EASY TO BECOME
UNSTUCK AND LOSE YOUR WAY ONCE YOU START 'TWEAKING' LOTS OF DIFFERENT SETTINGS.
