Advanced Anti-Feedback

If you've ever encountered embarrassing feedback onstage, you'll be pleased to know that the BA-330 is equipped with Roland's advanced Anti-Feedback technology. With a simple switch, the BA-330 automatically detects the howling point and eliminates feedback.

Onboard FX

Three high-quality effects are built-into the BA-330: Reverb, Delay, and Wide. The effects can be read more turned on/off independently for each channel. In addition, a master 2-band EQ is provided as well as EQ control for each channel.

Versatile Input

A wide range of instruments, microphones, and devices can be plugged into the BA-330 simultaneously. Two mono channels are provided for microphones or line-level instruments (XLR and 1/4" jacks), two stereo channels are provided for stereo instruments (1/4" L/R jacks), and a stereo Aux input channel is provided for CD players and other devices (RCA and TRS jacks).

Stereo Link

The BA-330's Stereo Link jack lets you cascade two units, giving you twice as many channels and the ability to position the two units on opposing sides of the stage.

This is the pa system for anyone out there buy it and try it you will be happy you did thanks Roland for a great Pa Sytem.
This little amp is a supprise the sound is that of a amp 3 times the size for a show setting. I have now bought a secound so that i can spread the sound to stero and for larger shows this is a amp for just about any size show and a great reinforemate sytem.
with 2 of these i will have more then i will need as far as inputs for everything are small 4 piece band need any club inside or out we can be heard with no problem. If we ever play Grand park down town i may need 2 or 4 more to cover the park but as for local shows inside or out this is a great system with just 2 cabs.
Ease of Use
Plung and play what else can you say
Built to last and a solid amp not to heavy just right for a 50 plus guitar player.
