This is a portable mixer with 6 input channels and 2 output channels, featuring a wide array of controls and input/output terminals, and also has a built-in power amplifier with a rated output of 30W + 30W. It is capable of handling various sound mixing applications, such as PA systems, recording, and instrumental ensembles. Instruments and microphones can be connected. I'm not very familiar with it, but I was able to confirm the sound by simply checking it with instruments and speakers. Other functions have not been checked.
