b)
Q (Q-factor)
is adjustable from 0.5 (wide band) to 2.0 (narrow band).
The Q determines how much the frequencies below and above the center frequency
are affected by the LEVEL adjustment in 'a.' Use the
q
or
p
buttons to choose a
Q-factor from 0.5 to 2.0 in steps of 0.5.
c)
Fc (center Frequency)
is adjustable from 30 to 150 Hz.
This is the point of maximum effect for the EQ LEVEL adjustment. All frequencies
above and below Fc are affected to a lesser degree, depending on the Q setting. The
frequencies are selectable using the
q
or
p
buttons. They vary for each band and
are listed below.
BASS EQ:
Fc = 30, 40, 50 60, 80, 100, 125, 150 (Hz)
MID EQ:
Fc = 500, 750, 1k, 1.5k, 2k, 3k, 4k, 5k (Hz)
TREB EQ:
Fc = 6k, 7.5k, 10k, 12.5k, 15k, 17.5k (Hz)
