Using The Microphone Jack - Casio CTK-720 User Manual

Basic Operations
Percussion sounds
Example: 241 DRUM SET
This tone assigns various percussion sounds to the keyboard.
See the "Percussion Instrument List" on page A-5 for full
details.
Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 32-note
polyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or auto-
accompaniment pattern is being played by the keyboard, the
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 16-note
polyphony.
NOTE
• When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.

Using the Microphone Jack

Connecting a commercially available microphone to the MIC
IN jack makes it possible to sing along with the keyboard's
built-in tunes. When connecting a microphone, be sure to first
adjust the MIC VOLUME to a relatively low setting, and then
adjust to the level you want after connecting.

"MIN" side.
