Master EQ
(PSR-740)
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 being 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 enjoy-
able.
The PSR-740 possesses a high grade five-band digital equalizer function. With this
function, a final effect—tone control—can be added to the output of your instrument.

band can be changed by
transmitting the system
exclusive message from an
external MIDI device to the
PSR-740/640 (see page

The digital equalizer adjusts the gain (amplitude change) in each of the five frequency
bands within a range of -12 to 0 to +12 decibels [dB].
The PSR-740 has five separate preset Master EQ settings (below) for instantly config-
uring the equalization for a variety of different music styles.
The equalizer can be set in two ways:
