OPERATION
JAZZ: JAZZ is specifically tailored toward stations that play mostly instrumental mu-
sic, particularly classic jazz (Coltrane, Mingus, Monk, etc.). It is a quiet preset with a
very clean, mellow high end to prevent stridency on saxes and other horns. It pre-
serves much of the qualities of the original recordings, doing light re-equalization.
The preset produces very low listening fatigue, so it is a good choice for stations that
want listeners to stay all day. Note that stations programming "smooth jazz" should
investigate the SMOOTH JAZZ preset, which is much louder and more "commer-
cial"-sounding.
LOUD: There are several LOUD presets.
LOUD-HOT was designed to be competitive with the sound of a popular processor
from another manufacturer, but without the competitor's dependence on composite
clipping. This preset is very bright and present, with up-front vocals. Release time is
medium.
In order to get the punchiest and loudest sound, beyond L
gressively reduce the protection provided by the distortion-controlling mechanism.
So L -M settings beyond 7.0 are progressively more risky and can exhibit audi-

ble distortion (as can the competing product!). In all cases, speech will be cleaner
than with the competing product and the bass is not permitted to "shut down" the
main clipper on bass waveform peaks.
LOUD-HOT LL is the low-latency version of LOUD-HOT.
LOUD-HOT+BASS is based on LOUD-HOT. It is tuned for the maximum amount of
bass we could add without creating obvious distortion on some program material.
For maximum punch, it uses the HARD bass clipper at higher L
This amount of bass may be excessive with certain consumer radios (particularly
"boom-boxes") that already have substantial bass boost. Use it with care.
LOUD-HOT+BASS LL is the low-latency version of LOUD-HOT+BASS.
LOUD+SLAM is similar to LOUD-HOT+BASS, but uses H

compressor (to control bass clipping distortion that could otherwise be introduced
by Hard bass clipping). This preset provides slamming bass punch, which it trades off
against bass cleanliness on certain program material. Because of the 18 dB/octave

from being clipped excessively, it can pump audibly when being used to the extreme

stereo enhancer setting, which is more extreme than the other LOUD presets.
