WHAY IS S.E.A. ?

What is SLAK.

All of the receivers from JVC incorporate the new JVC Sound Effect

Amplifier (SEA) system. Until the company popularized it by incorporat-

ing it into a receiver for consumers, this type of tone control system was

restricted to use in professional sound studios. With the SEA system,

todays stereo enthusiast has more freedom and control over the sound he

hears than was ever possible before. The advantages of the SEA system are:

1. It gives the listener complete control of sound throughout the entire
frequency range.

2. It enables the listener to create entirely new sounds.

3. It allows the listener to compensate for vagaries in room acoustics.

4. It permits the listener to compensate for sound characteristics peculiar
to such components as turntables, tape decks and speaker baffles.
Unlike the conventional tone controls found on most better receivers, the
SEA system divides the receivers total frequency range into 5 different
frequency zones. This permits more variation in the complex frequency
characteristics of individual frequency zones within the total frequency
range. As you can see by the graph, the SEA system permits a sharp slope
to be obtained from the very start. With ordinary tone controls, this slope
is limited to 6db/oct. Another advantage of the SEA system is that each
independent frequency zone can be increased or decreased within a very
narrow range from 10 to 12db/oct. Perhaps the largest advantage of all is
the SEA systems ability to control the difficult midranges. Ordinary tone

controls can only handle the extreme high and low ends.

In the case of the 5-zone SEA system, the operator has independent control
of the 40, 250, 1,000, 5,000 and 15,000Hz ranges. When a 7-zone SEA
system is utilized, the range is split up into even narrower zones.

How the SEA System Works

When listening to regular program sources, if the operator wants to boost
the low frequency response, all that is required is to boost the 40Hz or
2501-12 control. To bring out the important midrange-the ones closest to
that of the human voice-the 1,000 or 5,000Hz control should be boosted.
To increase extremely high end response, the 15,000Hz control can be
boosted. Conversely, all of these ranges can be lowered by deemphasizing
the response in each range.
