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

of 18 dB/octave. It has modified tuning in the band-1
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

bass response.

settings. Because this mechanism reduces clipper drive to prevent
waveforms from being clipped excessively, it can pump audibly when being used to
the extreme that it is in this preset. This is a sound texture that some people have
requested.
LOUD-PUNCHY is the quietest of the “loud” preset family. It is designed for a
bright, sizzling top end and very punchy lows. It is a good choice for stations that
feel that the
LOUD-HOT presets are too aggressive, but that think that the ROCK
presets are insufficiently loud for their market position.
MAINSTREAM MX 1-4: These modern-sounding presets are generally useful for popu-
lar music formats. They produce somewhat less high frequency energy than the
GREGG MX preset; their main difference is the amount of bass they produce. We
suggest auditioning them to see which one you prefer.
NEWS-TALK: This preset is quite different from the others. It is based on the fast
multiband release time setting, so it can quickly perform automatic equalization of
substandard program material, including telephone. It is very useful for creating a
uniform, intelligible sound from widely varying source material, particularly source
material that is “hot from the field” with uncontrolled quality. It extensively exploits
distortion control to achieve a very clean, highly compressed, but unclipped sound
quality.
SPORTS: Similar to NEWS-TALK except the AGC Release (AGC Release Time) is slower
and the Gate Thresh (Gate Threshold) is higher. This recognizes that most sports
programming has very low signal-to-noise ratio due to crowd noise and other on-
field sounds, so the preset does not pump this up as the NEWS-TALK preset would
tend to do.
ROCK, ROCK MX: We have included many of the 8500-style ROCK presets and have
made MX versions of ROCK-MEDIUM, ROCK-SOFT, and ROCK-SMOOTH, which are
cleaner and punchier than their 8500-style counterparts. ROCK-SOFT MX and
ROCK-SMOOTH MX are intentionally tuned for a smooth, mellow high frequency
balance, which can complement female-skewing formats .
ROCK-DENSE , ROCK-MEDIUM , and ROCK-OPEN provide a bright high end and
punchy low end (although not as exaggerated as the URBAN presets). A midrange
