the
"C)" (•~ I) position. Regardless of the switch setting, the
primary circuit is always
"live" as long as the power cord is
connected to an electrical outlet.
Note:
•With the power switch in the OFF position, there is still a slight
power consumption (about 3 watts). This is in order to assure
the retention of the
"most recent" memory and the preset-
memory functions.

•Pink noise is used for measurement and
correction of the sound field frequency re-
sponse because it is mostly within the audi-
ble range, its energy distribution is uniform ,
and it has a wide frequency band.
•Because pink noise has large instantaneous
level fluctuations, the display may fluctuate .

BEFORE MEMORIZATION OF EQUALIZATION CURVES
This unit has eight memory areas; five of these are available to
the user, and can be changed ; the other three are preset (fixed)
music curves and cannot be changed.
• Memory areas for the user
•As many as five pairs (left/right channels) of equalization
curves can be entered into memory areas 1 through
5.
•When an automatic sound-field correction is made, the
equalization curve is automatically entered in memory area
5.
• Fixed-equalization-level memory areas
Equalization curves which are appropriate to the following
three types of music have already oeen preset to memory
areas 6 through 8, thus making it possible to enjoy music
listening at a touch of a button . (Other equalization curves
cannot be entered into these memory areas.)
MEMORIZATION OF EQUALIZATION CURVES

addition, the level for the range from 4 kHz through 16 kHz
has been increased in order to obtain a characteristic in
which there is a tauter high range and low-range build-up.
Memory area 7 (jazz)
The level for 63 Hz and 100 Hz is increased, and moreover
the level for 4 kHz and 8 kHz is moderately increased ,
in
order to provide a modulated, soft sound.
Memory area 8 (vocal)
The 2-kHz range is increased by 4 dB and the 4-kHz range is
increased by 2 dB; in addition, the 500-Hz range is reduced
by - 4 dB, thus providing a clear characteristic with excellent
vocal emphasis.

EXAMPLES OF APPLICATIONS UTILIZING THE SH-8066 FUNCTIONS
The sound level of the 12 frequency divisions in the 25 Hz-16
kHz frequency range can be easily and selectively corrected by
means of the band level control
of this unit.
1. Complete audio room
correction-including the correction of
both stereo equipment and room acoustics.
2. Personalized sound quality control.
3. Creating an original tape collection of tapes tailored to your
car stereo, or tapes of live recordings, etc.
4. Reduction of noise, prevention of howling. These are merely
a few of the possibilities that sound quality and room acoustic
correction open up for the serious listener.
• Correcting room acoustics
Each room has its own particular effects on frequency character-
istics. These effects are determined by a number of conditions,
such as rooms size, furnishings, etc.
The 12 separate divisions of the band level control on the
SH-8066 make it possible to selectively correct only the
frequency ranges necessary to suit the conditions of each
listening room .
An example of room acoustics correction
In order to correct the peaks and dips in bass sounds caused by
reflection, reduce the 250 Hz level 4- 6 dB and then, raise the
level of sounds below 63 Hz and above 4 kHz slightly.

• Cutting the noise from live recording tapes
Live tapes recorded outdoors generally contain popping noises
caused by wind and various other noises from the surrounding
area.
In order to effectively eliminate wind noise, cut bass
sounds below 63 Hz and raise the level of sounds
in the 250
Hz-500 Hz range. Then control sounds made by birds, etc
., with
a 4 kHz and
or 8 kHz adjustment.

• Making tapes for car stereos
Tapes can be made exc lu sively for the li stening conditions inside
a vehicle. Merely raise the 63 Hz level 4 dB and completely cut
the levels below 40 Hz that are so troublesome for car stereo
reproduction. For medium and low frequencies, centering on the
250 Hz vicinity, lower the modulating effect by raising the 4
kHz- 8 kHz vicinity by 2- 4 dB.

• Cutting noise from discs
Noises from warped discs are low frequency noise components.
Lowering the sound level of the 63 Hz vicinity can eliminate
these.
To cut noise
in old discs, set all direct-equalization level controls
to the "flat" (center) position, and then move them individually to
the
-12 dB position to find the noise component.
Then, working from this clue, cut the noise so as not to
deteriorate the tone quality.

• Reducing tape hiss
Tape hiss can be effectively reduced by slightly raising the level
of high frequency (above 2 kHz) sounds during tape deck
recording, and then lowering them during playback.
Note:
If sounds above 8 kHz are raised too much, distortion may result
in the tape deck. Prevent this by watching the level meters of the
tape deck and setting the recording levels appropriately.
