The BA-330 has three built-in high-quality effects: Reverb, Delay, and Wide, each channel can be independently turned on/off. In addition, there is a 2-band equalizer to provide sound control for each channel.

Support multiple input types

The BA-330 can connect instruments, microphones, and music playback devices at the same time. The convenient control device on the panel can immediately adjust the mix. The two mono channels can be used for microphones or audio connection instruments (XLR and 1/4"1/2 stereo channels can be connected to stereo instruments (1/4" L/R terminals), a stereo auxiliary input channel can be used to connect CD players and other devices (RCA and TRS terminals).
