Preamp is controlled by four parameters:
•
Preamp gain
– Value of signal’s amplification in decibels – in range : [0 dB … 100 dB].
•
Lo cut
– It’s a hi-pass filter’s frequency – in range: [0 Hz … 300 Hz].
•
Hi cut
– It’s a low-pass filter’s frequency – in range: [1.5 kHz … 8 kHz].
•
On
/
Off
– Turning off a low-pass filter completely (
Hi cut
).
Lo cut
and
Hi cut
control the bandwidth of the input signal which passes through the preamp.
