FM Final Clipper
Touching the FINAL metering on the front panel touchscreen brings up the controls
for the FM clipper.
Main Clipper Drive
Determines the amount of drive to the distortion-cancelled final clipper.
The normal range for most presets is between 0dB and +3dB. Higher numbers
will increase loudness but have the potential to add distortion.
To change the main clipper drive, tap the control. You will see a green ring
indicating the control is active and ready to be changed. Use the front panel
knob to select the type of release. The processing effect will change in real
time as you move the knob. Once you have reached the desired setting, push
in the knob to confirm the new value.
Multipath Limiter
In order to make stereo enhancement “play nice” with the majority of stereo
receivers in real-world listening environments with all types of program material,
it is preferable to have some sort of controlling mechanism in place to ‘man-
age’ the amount of L-R energy present in the transmitted signal as a function of
program material. This is precisely what the Multipath Limiter does.
When active, the multipath limiter will restrict the L-R information in the
audio signal to a percentage of the overall L+R, this control is calibrated in
%. In almost all cases, we recommend starting with a setting of 80%. If your
radio station is prone to receiver blend, reduce the control to 70, 60 or 50% and listen for
improvements.
