FILTER CONTROL BOARD
– OPERATION
The two switches on the filter control board determine whether the NOISE FULL & NOISE HALF buttons
control the noise level or the filter mode.
1 When the left (HP) switch is in the
up
position the
NOISE FULL
button will select highpass mode and
noise full no longer works.
2 When the right (BP) switch is in the
up
position the
NOISE HALF
button will select bandpass mode
and noise half no longer works.
Please note: The 4-Voice expansions were shipped with the filter control board included. If it installed you
can use it to have different filter modes for the top four voices. The bottom four voices will not have filter
control and you will lose the noise half and/or noise full volume features if the bandpass and/or highpass
modes are enabled.
