S.E.A. PRESET PATTERNS
Try these patterns to increase your listening pleasure with
different types of music. These are suggestions from JVC of
settings which will be most suitable for these types of tunes.
MORE ABOUT S.E.A.
JVC's exclusive tone control system
S.E.A. divides the receiver's output into five separate frequency
bands with center frequencies of 40, 250, 1 000, 5 000 and
15 000 Hz. The controls have click positions above and below
the center or FLAT position so that the response in each band
can be varied by +12 dB.
40 Hz Boost to bring out the rich tones of such instru-
ments as the organ.
250 Hz Boost to add clarity to upper bass sounds such as
woodwind instruments and cellos. Cut to eliminate
speaker boom.
1000 Hz_ Effective to emphasize or deemphasize the human
voice and certain instruments.
5000 Hz Boost to add clarity to trumpets and violins. Cut
to reduce upper mid-range response.
15 000 Hz Boost to give a finer high frequency response. Cut
to eliminate harsh sounds.
S.E.A. makes possible more flexible control over tone so that
various special effects can be obtained that were not possible
with conventional bass and treble tone control systems. With
S.E.A. used judiciously, the sound can be tailored to com-
pensate for the acoustic properties of your listening room, the
characteristics of your audio system and the properties of dif-
ferent types of music.
Compensation for room acoustics
Booms with many curtains and furnishings tend to. absorb
low frequency sounds, in which case the 40 Hz and 250 Hz
controls should be boosted. In rooms which are relatively
sparsely furnished, sound is reflected. In small rooms highs
tend to be emphasized and in large rooms, lows. These dif-
ferent properties can be compensated for by proper adjust-
ment of S.E.A.
Compensation for the characteristics of components
Almost all moving magnet cartridges have peaks in their re-
sponse curves between 10000 and 15 000 Hz and produce
harsh high frequency sounds. Speakers also are not always
perfect. Some airtight enclosures reproduce low frequencies
below 100 Hz poorly and cause harsh sounding midrange and
high frequencies. These characteristics of audio systems, which
cannot be compensated for by conventional tone control
systems, can be perfectly compensated for by S.E.A.'s five
controls.
