Mi EXAMPLES OF APPLICATIONS
HB 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 400 Hz
range. Then contro! sounds made by birds, etc., with a 6.3 kHz
adjustment. a eee

(dB) 63Hz 160H2 400Hz 1kHz 25kHz 6 3kHz 16kHz FULL RANGE (dB)
@ Producing clear vocals
For female vocals, raise the level of the 1 kHz~2.5 kHz range by
2~4 dB. To rectify omission, raise the level of the 6.3 kHz vicinity
slightly.
Male vocals can be improved by raising the level of the 400
Hz~2.5 kHz range.
Below is an example of a female vocal correction.

@ Making tapes for car stereos
Tapes can be made exclusively for the listening conditions inside
a vehicle. Merely raise the 63 Hz level 4 dB.
For medium and low frequencies, centering on the 400 Hz
vicinity, lower the modulating effect by raising the 2.5 kHz~6.3
kHz vicinity by 2~4 dB.

@ Adding some power to disco music
Increase the power of bass guitars and bass drums by raising the
level of the 63 Hz~160 Hz range, and raise the level of sounds
from 2.5 kHz to 16 kHz. The result will be greatly emphasized low
frequency sounds and strong, clear high frequency sounds.
(0B) 63Hz 160Hz a00Hz tkHz 25kHz 6.3kHz 16kHz FULL RANGE (dB)
@ Reducing tape hiss
Tape hiss can be effectively reduced by slightly raising the level
of high frequency (above 2.5 kHz) sounds during tape deck
recording, and then lowering them during playback.
(This can be done conveniently by using the reverse button.)
Note:
‘If sounds above 6.3 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.
