Switching the H.P.F. OUTPUT switch
After the connection is made, select the desired frequency
point (80 Hz or 100 Hz) with the H.P.F. OUTPUT switch.
(Normally, it is recommended to select the frequency point
nearer to the main speakers' minimum reproduceable
frequency.)
Frequencies higher than the selected frequency are output
from the H.P.F. OUTPUT terminals.
