Advanced Anti-Feedback
If you've ever encountered embarrassing feedback onstage, and most of us have, you'll be pleased to know that the BA330 is equipped with Roland's advanced Anti-Feedback technology. With a simple switch, the BA330 automatically detects the howling point and eliminates feedback.

Onboard FX
Three high-quality effects are built-into the BA330: Reverb, Delay, and Wide. The effects can be 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 inch jacks), two stereo channels are provided for stereo instruments (1/4 inch L/R jacks), and a stereo Aux input channel is provided for CD players and other devices (RCA and TRS jacks).

Stereo Link
The BA330’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.

    What is your opinion of this product?
    Bottom Line, Rugged Roland Build, Not a unit you would hesitate to rely on.I have been on music in 1974.First a musician and now a Dj.Cant beat the build or the quality.I just sold my Bose L1 Compacts and replace them with 2 of these and Im glad I did.The L1 compacts for someone who gigs a lot can be a bit fragile and also I find the feedback suppression to be much better with the Rolands. Also the Bose Systems have no effects.For my purpose these are awesome for Wedding Ceremonies, beach weddings,Karaoke, at weddings if there are family musicians they can plug right in.Very flexible and very well built!
