Continued from preceding page.
Bass control:
The bass control gain can be maximum boost +15dB position and maximum cut -15dB position
(0dB/±1.25dB/±2.75dB/±4.75dB/±7dB/±9.5dB/±12.25dB/±15dB) SCF.
The bass control center frequency 60Hz/80Hz/100Hz/200Hz can be selected.
The bass control quality factor 1.0/1.25/1.5/2.0 can be selected.
Middle control:
The middle control gain can be maximum boost +12.25dB position and maximum cut -12.25dB position.
(0dB/±1.25dB/±2.75dB/±4.75dB/±7dB/±9.5dB/±12.25dB) SCF.
The middle control center frequency 600Hz/800Hz/1kHz/2kHz can be selected.
The middle control quality factor 1.0/1.25/1.5/2.0 can be selected.
Treble control:
The treble control gain can be maximum boost +12.25dB position and maximum cut -12.25dB position.
(0dB/±1.25dB/±2.75dB/±4.75dB/±7dB/±9.5dB/±12.25dB) SCF.
The treble control center frequency 8kHz/10kHz/12.5kHz/15kHz can be selected.
The treble control quality factor 1.0/1.25/1.5/2.0 can be selected.
Fader control: 0dB to -79dB/-∞ (1dB steps)
