6. Input Indicators
The source selected by the input select buttons is
indicated.
7. EQUALIZER LEVEL buttons
Independent level controls for the right, left or both
channels are provided for each of the ten frequency bands
with a ±12 dB range of equalization. These button
operations are effective only when the EQ button is set to
ON even during the display changes.
•
30 Hz band
Decreasing this level eliminates very low frequency
rumble, or compensates a warped disc.
Increasing this level emphasizes the very low frequencies.
•
60 Hz band
Decreasing this level reduces AC line hum and the lower
tone.
Increasing this level emphasize low tones, such as pipe
organ, drums, bass, etc.
•
120 Hz band
This range supports the lower end of the music and
controls overall depth. Decrease this level to eliminate
"boomy bass" caused by room acoustics.
•
240 Hz band
This is the middle-to-lower tone range, but it has an effect
on the overall sound. Mainly, the richness of the strings can
be controlled. When strings are overly warm under actual
listening conditions, decrease this level.
•
480 Hz band
This range is the foundation of music including both
instruments and the human voice and it controls the
overall power of the sound. As this level is increased,
midrange sound will become more forward.
•
1 kHz band
This range affects the presence of the music (depth of
tone), and is especially effective when playing back
vocals. Increasing or decreasing this level will cause the
vocals to be more "up front" or more reserved.
•
2 kHz band
This is the frequency range where the human ear is most
sensitive. Boosting the level slightly will add brilliance,
crispness, etc. to instruments. Cutting the level slightly
makes for easy listening.
•
4 kHz band
The human ear is also highly sensitive in this range. Mainly
effective for increasing/decreasing the harmonics of the
primary tone. Boosting this range a bit makes strings more
intense. Over-intense, tiresome music is easily listened to
when the level is decreased.
•
8 kHz band
High frequency range. Strings, horns, etc. will be
emphasized and this gives a slight difference in tone glaze
and quality. Decreasing the level reduces overemphasized
consonants in vocals and objectionable tape hiss.
Increasing the level, on the other hand, improves the
sharpness of such instruments as cymbals.
•
16 kHz band
Super-high frequency range. This affects high harmonics
rather than the fundamental tones of the instruments
themselves, and has an effect on the delicacy and
atmosphere of the music. Boosting this level adds a
delicate, fresh sound to cymbals, triangles, etc.
8. Preset memory buttons
These buttons are used to store equalizer curves in the
preset memory. By storing desired curves in the memory,
they can be recalled by pressing these buttons. Up to 4
equalizer curves can be stored in memory. In addition,
three memories are provided with storage of equalizer
curves that are optimized for VOCAL, FUSION and DISCO
music. These are stored under memory buttons 5 to 7, and
cannot be rewritten by the user. The equalizer curve
obtained by auto equalization is automatically stored under
the ROOM EQ button.
9. MEMORY button
To store the equalizer curve being displayed in memory,
press this button. Then, while the MEMO indicator is
flashing (for about 5 seconds), press one of preset
memory buttons (1 — 4).
10. EQ button and EQ REC button
To start equalization of a sound, press the EQ button so
that the EQ indicator lights.
To record the equalized sound, press the EQ button then,
the EQ REC button so that the EQ REC indicator lights.
11. Input select buttons
Press one of these buttons to select the source to be
listened to.
SOURCE:
To play the source connected to the amplifier,
or to record onto cassette deck 1 or 2.
TAPE1:
To play cassette deck 1 connected to the
equalizer, or to dub the sound to cassette deck 2.
TAPE2:
To play cassette deck 2 connected to the
equalizer, or to dub the sound to cassette deck 1.
12. SUBSONIC FILTER button and control
Used to cut off unnecessary low frequency. If the program
source to be played contains such super low sound, press
the SUBSONIC FILTER button to turn the subsonic filter
ON. The frequency to be cut off can be adjusted by the
slide control.
13. Channel buttons
These are used to select the channel(s) subject to the
equalizer level control or spectrum display.
LEFT:
To display the equalizer levels or spectrum of the
left channel only.
RIGHT:
To display the equalizer levels or spectrum of the
right channel only.
L + R:
To display the equalizer levels or spectrum of both
the left and right channels. With the equalizer level
display, the left channel levels are displayed more
brightly than the right channel levels. With the spectrum
display, the sum of the left and right spectra is
displayed.
14. DISPLAY mode buttons
These are used to select the display mode.
EQ CURVE:
To display the equalizer levels.
ANALYZER:
To display the spectrum.
15. AUTO ROOM EQ button
Press for auto equalization.
This button functions only when the supplied microphone
is connected to the MIC jack.
