The input jacks include microphones 1 and 2, a guitar / keyboard, and tapes 1 and 2 / lines for mixing in various combinations.
You can also adjust the output level collectively on the master volume.
Microphones 1 and 2 each have a pan pot function, so you can move the vocals left and right and change the sense of distance between the two microphones.
The graphic equalizer can be adjusted by ± 12 20 Hz to 20 kHz, each of which can be adjusted by ± 12 dB.
Equipped with an echo / chorus function, you can enjoy the echo effect or chorus by yourself.
