5 USB player tone control

As usual for many 1-knob tone controls the USB player features shelving characteristics. Illustra-
tion 4.6 exhibits this behaviour.

5.0.1 Adaptive tone control of Channel 1 and 2

The key function of the adaptive tone control is its ability to show specialised control characterist-
ics tailored to the requirements of different signal sources. For effective control an instrument
demands for different center frequencies for equalisation than a line source. To meet these indi-
vidual needs the adaptive tone control will alter the boost and cut frequencies and also set an
appropriate gain margin (range: + / - 15 dB max.). This mode of operation very much resembles a
parametric equaliser, whereas here several parameters are altered simultaneously (center fre-
quency, Q, gain). Illustration 4.7 portrays this principle:
