• Bass control :
The bass control gain can be maximum boost +12dB position and maximum cut -12dB position.
( +12dB to -12dB in 2dB steps.)
The bass control center frequency 70Hz/100Hz/120Hz can be selected.
The bass control quality factor 1.0/2.0 can be selected.
• Middle control :
The middle control gain can be maximum boost +12dB position and maximum cut -12dB position.
( +12dB to -12dB in 2dB steps.)
The middle control center frequency 700Hz/1KHz/1.2KHz can be selected.
The middle control quality factor 1.0/2.0 can be selected.
• Treble control :
The treble control gain can be maximum boost +12dB position and maximum cut -12dB position.
( +12dB to -12dB in 2dB steps.)
The treble control center frequency 7KHz/10KHz/12KHz can be selected.
The treble control quality factor 1.0/2.0 can be selected.
• Fader control :
The fader volume can be attenuations by one of 16 levels. Independent control each four channels.
(A total of 16 settings with attenuations of 0 to –2dB in 1dB steps, -2 to -20dB in 2dB steps, and
-30, -45, -60, and -∞dB settings.)
• Subwoofer control :
A total of 81 positions from 0 to -79dB in 1dB steps and -∞dB.
The low pass filter 80Hz/120Hz/160Hz can be selected. Fedar two channels output only of rear or either of the
subwoofer output is selected.
