Characteristics of each frequen.
cy range
The following are examples of typical applications with regards to
the equalizer band settings.
These statements am used in a general manner of speaking and
may not hold true in all cases.
Deep bass range
The sounds of the bass, drums, eto. are dramatically sb'ongthened.
Bass range
This range provides the sounds of the saxophone, trombone, etc.
sounds can be clarified, # indistinct, by redudng this setting.
Mid-bass range (the fundamental range
for music)
This control can be used to reinforce the sounds of male vocals,
etc.
Mid-range
This control can be used to add clear presence and realism to
female vocals, etc.
12.5 Id-lz I Mid-high range
This range provides clarity and color variations to stringed instru-
ments, etc.
16.3 kHz I Treble range
This control can be used to brighten the sounds of the flute and
similar instruments. If sounds seem too jarring, a softness can be
applied by reducingthe setting.
Super-treble range
This control can be used provide an extra measure of delicate
vibration to the sounds of the cymbals, triangle, etc.
If tape "hiss" noises are annoying, this control's setting can be
reduced to alleviate such noises.
Examples of appUcations
By using the seven band-level controls, various corrections of the
sound field and tone quality are possible.
For creation of a sound field in the listening
room.
Correcting room acoustics
Each room has its own particular effects on frequency character-
istics. These effects am determined by a number of conditions,
such as room size, furnishings, etc.
The 7 separate divisions of the band level control on this unit
make it possible to selectively correct only the frequency ranges
necessary to suit the conditionsof each listening room.
An example of room ac_u_ica corre,_on
in order tO correct the peaks and dips in bess sounds caused by
_reflection, reduce the 160 Hz level 4-6 dB and then, raise the
level of sounds below 63 Hz and above 6.3 kHz vicinity slightly.
For editing =live" recordings made on tape, etc.
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 I-Iz and raise the level of sounds in the 400 Hz
range. Then control sounds made by birds, etc., with a 6.3 kHz
adjustment.
For creation of unique, individually personal-
ized sounds.
Producing clear vocals
For female vocals, raise the level of the I 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 RHz range. '
Below is an example of a female vocal correction.
