The Digital Equalizer (PSR-730)<br />

Usually an equalizer is used to correct the sound output from amps or speakers to<br />

match the special character of the room. The sound is divided into several frequency<br />

bands, then by raising or lowering the level for each band, the correction is made.<br />

Adjusting the sound you play according to the genre—classical music more refined,<br />

pops music more crisp, and rock music more dynamic—can also serve to draw out the<br />

special characteristics of the music and make your performance more enjoyable.<br />

The PSR-730 possesses a high grade 5 band digital equalizer function. With this<br />

function, a final effect—tone control—can be added to the output of your instrument.<br />

The digital equalizer adjusts the gain (amplitude change) in each of the 5 frequency<br />

bands within a range of -12 to 0 to +12 decibels [dB]. Try listening to each of the five<br />

preset equalizer settings and compare them.<br />

Using the Digital Equalizer (PSR-730)<br />

If you press the [DIGITAL EQ] button, the DIGITAL EQ icon will light up, and<br />

the Digital EQ effect will be turned on. After setting the Digital EQ type, the equalizer<br />

effect will be applied to the overall output of the PSR-730.<br />
