For effective adjustment of the HIGH CUT control
First set this control at about the main speakers’ rated
minimum reproduceable frequency. Then turn up the
VOLUME control gradually and set it at a level where you can
obtain a little more bass effect than when this unit is not used.
On the basis of this setting, if desired, adjust the VOLUME
control and the HIGH CUT control again.
*
The main speakers’ minimum reproduceable frequency can
be looked up in the speakers’ catalog or owner’s manual.
