ng the S.E.A. Gra
The S.E.A. Graphic Equalizer breaks down the audible frequency
range into seven bands. Each band of tones can be adjusted as dis-
ired by the listener. Thus allowing you to make the necessary ad-
justments in the presicely appropriate frequency bands.
*You can customize the sound to your taste.
*You can correct subtle frequency to suit the acoustic charac-
teristics of your listening room.
*You can compensate for the conditions of audio equipment.
Note:
The S.E.A. Graphic Equalizer does not work on the CENTER and REAR
speaker sound.
= Recalling a preset pattern
A total of 10 preset patterns can be used: 5 programmed preset pat-
terns, and 5 manual patterns which you create (SEA-A through E)
1. Press the SEA key.

The Dot Display normally shows the input signal levels.
It will change to SEA level for about 5 seconds when the SEA,
PRESET, LEVEL, FLAT, REVERSE, or FREQUENCY keys are pressed.
2. Call a preset pattern with the PRESET keys.

« After recalling these pattern, you can further change each
frequency band to suit yourself. However, since they are represen-

Note:
When a frequency has been called, press the LEVEL keys while the
frequency is displayed (about 5 seconds). If the display is cleared
before you press the LEVEL keys, it can be recalled by pressing either
FREQUENCY keys or LEVEL keys
@ The SEA key enables you to compare the sound corrected by
S.E.A. with the original (uncorrected) sound during the procedure
for creating an S.E.A. pattern. Pressing the SEA key to turn the
S.E.A. OFF lets you hear the uncorrected sound. When you press
the S.E.A. key again, the S.E.A. pattern being created is recalled
and the corrected sound can be heard

The sound corrected by S.E.A. can be recorded on the tape deck
connected to the TAPE 1 terminals

4. Operate the recording procedure.
Notes:
* SEA recording is not available with the tape deck connected to
the TAPE 2, VCR 1, and VCR 2 terminals.
© The REC key is not functional when the SURROUND key is ON.
The reverse feature offers you a noise reduction effect during tape
recording. First, record sources with emphasis on high-piched tones
by using SEA; during playback, activate reverse SEA, to cut hissing
noise inherent in tape recording.
To reverse the porality of the S.E.A. characteristics, press the
REVERSE key
Frequency band responses
63 Hz: Raise to emphasize the very low base response of organs, drums,
and contrabass. When de-emphasized, eliminated unclear response at low
frequencies.
160 Hz: Emphasize to obtain a more expanded low sound. De-emphasize
to eliminate unclear sound caused by large or nearly empty listening rooms.
400 Hz: This frequency range is the base on which music is construct-
ed. Emphasize to put real punch in your music:
1 kHz: Most effective in emphasizing or de-emphasizing the human voice.
2.5 kHz: The human hearing is most sensitive to this freuqncy. If the music
sounds hard or metallic, de-emphasize it.
6.3 kHz: This frequency band varies the tonal expression, influencing the
subtleties of the music.
16 kHz: Boosting this frequency range suitably adds to the delicacy of
highs, with cymbals and triangles resounding in a more ear-pleasing man-
ner, and provides a feeling of extension.
