late the high frequency balance of recently recorded material.
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: There are several ROCK presets:
ROCK-LOUD is very bright and present, with up-front vocals. Release time is me-
dium.
In order to get the punchiest and loudest sound, beyond
we progressively reduce the protection provided by the distortion-
controlling mechanism. So
sively more risky and can exhibit audible distortion (as can the competing
product!). Speech will nevertheless be cleaner than with competing
products and the bass is never permitted to "shut down" the main clipper
on bass waveform peaks.
ROCK-GENERAL provides a bright high end and punchy low end (although not as
exaggerated as URBAN). A midrange boost provides enough presence energy to en-
sure that vocals stand out. A modest amount of high frequency coupling (deter-
mined by the BAND CLIPPING 3>4 setting) allows reasonable amounts of automatic
HF equalization (to correct dull program material), while still preventing exagger-
ated frequency balances and excessive HF density.
The ROCK-MEDIUM and ROCK-OPEN variations refer to the compression density,
which is determined by the release time settings in the AGC and multiband limiter
sections.
These three presets are appropriate for general rock and contemporary program-
ming. All of these presets have distortion control implemented at their nominal lev-
els of L -M to ensure clean speech. At high L

control may be relaxed somewhat to increase bass punch.
There are also several more ROCK presets that are intended for gentler formats:
ROCK-LIGHT has an open sound with little audible compression and less brightness
than the first three presets. It is a compromise between ROCK-OPEN and ROCK-
SOFT.
ROCK-SOFT has a mellow, easy-to-listen-to high frequency quality that is designed
for female-skewing formats. It is also a candidate for "Quiet Storm" and "Love
Songs" light rock or light urban formats.
ROCK-SMOOTH has the same mellow, easy-to-listen-to high frequency quality as
ROCK-SOFT, but with more density. Again, it is a good choice for female-skewing
formats, but where you need more compression and density than you get with
ROCK-SOFT.
