OPERATION

ORBAN MODEL 8300

to keep the frequency balance consistent from record to record (espe-
cially those recorded in different eras). In addition, for background music
formats, these settings ensure that your sound doesn’t lose its highs and
lows. Because it creates a more consistent frequency balance between
different pieces of source material than does the Two-Band structure,

SLOW

is almost always preferable to the Two-Band structure for any

popular music format.

The

Medium Slow

settings (

MED

and

MED2

) are appropriate for more

adult-oriented formats that need a glossy show-business sound, yet
whose ratings depend on maintaining a longer time spent listening than
do conventional Contemporary Hit Radio (CHR) formats. With the single-
ended noise reduction activated, it is also appropriate for Talk and News
formats. This is the sound texture for the station that values a clean, easy-
to-listen-to sound with a tasteful amount of punch, presence, and
brightness added when appropriate. This is an unprocessed sound that
sounds just right on music and voice when listened to on small table ra-
dios, car radios, portables, or home hi-fi systems.

The

Medium Fast

settings (

MFAST

and

MFAST2

) are ideal for a highly

competitive Contemporary Hit Radio (CHR) format whose ratings depend
on attracting a large number of listeners (high “cume”) but which does
not assume that a listener will listen to the station for hours at a time.
This is the major market competitive sound, emphasizing loudness as well
as clean audio. The sound from cut to cut and announcer to announcer is
remarkably consistent as the texture of music is noticeably altered to a
standard. Bass has an ever-present punch, there is always a sense of pres-
ence, and highs are in perfect balance to the mids, no matter what was
on the original recording.

The

Fast

setting is used only for the

TALK

and

SPORTS

factory pro-

gramming formats. Processing for this sound keeps the levels of an-
