Drive
This control adjusts the amount of Input Drive to the Bass
Tools algorithm. Higher drive settings make it work harder
and generate higher levels of harmonics. The Drive control
adjusts the amount of drive to the Bass Tools and is adjustable
over a range of -6dB to +12dB. Adjustment is best done by
ear with percussive source material.
Style
Two Bass Tools operating styles, plus Off,
are available. The Hard setting has a transfer
function occupying approximately 1dB of
transition amplitude. The waveform control is
fairly abrupt and generates low order harmonics.
The Soft setting operates with a transfer func-
tion occupying approximately 2dB of transition
amplitude. Therefore the control is less sharp
than the hard setting, generating more low order
harmonics. While the two settings may appear
to be almost the same, the 1dB difference in
transfer ratio creates a
significant
difference in
how the two Bass Tools styles sound on actual program material. When Off is selected,
the Bass Tools processing is bypassed.
Frequency
The Freq control is simple. All audio below the frequency selected is processed by
Bass Tools. Smoother bass can be had with settings above 200Hz, which is recommended.
