THE NBS UNIVERSAL TONE CONTROL
You normally think of a tone
control in terms of crude
"bass" and "treble" knobs. As a practical matter, such
controls are much too coarse to accomplish anything but a gross tonal modification.
If you have a lot of recordings and
use really good playback equipment, you have undoubtedly observed that many
recordings are tonally deficient in some way. Maybe a little too bright, not
quite enough deep bass, not enough presence and so on.
This problem arises from two facts:
first, you are not listening in the exact same way as the people who produced
and balanced the recording, and second, your personal preferences may differ
from those of the producer. These differences of taste and preference are not
susceptible to argument, they simply are what they are.
The most important determinant of
tonal balance is the frequency response. Small variations in frequency response
can have a very large effect on perceived tonal balance.
Hence, the NBS Universal Tone
Control.
It offers adjustment of the
frequency response in 6 bands which subjectively correspond to the attributes
of:
Powerfulness,
deep bass 40
Hz control
Body,
solidity, mid-bass 150 Hz control
Warmth,
lower midrange 500 Hz control
Presence,
upper midrange 2500 Hz control
Brightness,
sibilance, low treble 5 kHz control
Brilliance,
high treble 10 kHz control

The amplitude of each band is
independently adjustable, either to boost it or to reduce (attenuate) it. Very
fine adjustments are possible.
Output level trim controls are
provided for each channel because sometimes changing the tonal quality will
affect the apparent left-right balance. This can be corrected using these
controls.
A Bypass mode is also available so
that the adjusted result can be easily compared to the original sound.
A distinguishing feature of the NBS
Universal Tone Control is that it allows correction of the tonal balance
without corrupting the quality of the signal. As a result it is a useful
addition to even the highest performance system.
