Adjusting The Equalization - Yamaha P-100 Owner's Manual

Adjusting the equalization

The P-100's equalizer works much like the three-band graphic equalizers found on many portable stereo sets. It allows
you to adjust the P-100's output in three frequency ranges, LOW, MIDDLE and HIGH.
Slide the slider for each range up to increase the level of output, or
down to decrease output in that range. The graph below should
give you an idea how you can use the equalizer to modify the
sound output by the P-100.
