The Digital Equalizer (PSR-730)
Usually an equalizer is used to correct the sound output from amps or speakers to
match the special character of the room. The sound is divided into several frequency
bands, then by raising or lowering the level for each band, the correction is made.
Adjusting the sound you play according to the genre—classical music more refined,
pops music more crisp, and rock music more dynamic—can also serve to draw out the
special characteristics of the music and make your performance more enjoyable.
The PSR-730 possesses a high grade 5 band digital equalizer function. With this
function, a final effect—tone control—can be added to the output of your instrument.
Example) 04 (Bright)
If you press the [DIGITAL EQ] button, the DIGITAL EQ icon will light up, and
the Digital EQ effect will be turned on. After setting the Digital EQ type, the equalizer
effect will be applied to the overall output of the PSR-730.
