The Roland BA-330 Portable PA System has a four-channel configuration, with two channels dedicated for microphones or musical instruments, and two other channels for standard 1/4″ stereo inputs.

The Roland BA-330 Portable PA System Main Features Include:
• All-in-one portable digital PA system suitable for use anywhere
• Powerful high-quality stereo sound for audiences of up to 80 people
• No setup required, just plug in and go!
• Powered by AC power or eight AA batteries
• Four custom-designed 6.5Œ speakers and two tweeters for wide stereo projection
• Built-in effects: EQ, reverb, delay, and wide (on/off per channel)
• Four-channel configuration: two channels for mic/instruments plus two channels for stereo inputs
• Stereo Aux input with dedicated volume-control knob
• Advanced Intelligent Anti-Feedback function
• Built-in tilt-back stand enables optimal monitoring angle
• Speaker-stand adaptor for mounting on a standard speaker stand

Each channel on the Roland BA 330 has its own independent tone adjustment and effects switching for built-in effects, such as EQ, reverb, delay and widening. A Stereo Link function allows you to pair the BA-330 to work in tandem to provide an extra-wide stereo spread.

Powered by a high performance digital stereo amplifier, the BA-330 Portable PA System features four custom-designed 6.5Πstereo speakers and two tweeters, positioned for wide stereo dispersion. While the built-in tilt-back stand enables the unit to be angled up for better sound monitoring, the BA-330 Portable PA System also can easily be mounted on a speaker stand.

The Roland BA-330 Portable PA System features a unique Intelligent Anti-Feedback function previously unavailable in self-contained portable PA systems. During use, the BA-330 can automatically detect potential feedback possibilities and eliminate it immediately. This is a huge advantage over manually adjusting volume levels, as it allows performers to place the portable PA system behind them and easily hear themselves without experiencing feedback.

Designed to deliver high-quality stereo sound for audiences of up to 80 people, the Roland BA-330 Portable PA System can run on standard AC power or eight AA alkaline or Ni-MH rechargeable batteries. The switchable output power allows the user to switch between the maximum power and the energy-saving Eco modes to preserve battery life. The BA-330 Portable PA System is also amazingly efficient, delivering a sound pressure level of 109 dB, comparable to much larger mid-range sound systems.

Advanced Anti-Feedback
If you?ve ever encountered embarrassing feedback onstage, and most of us have, 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 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 1/4Πjacks), two stereo channels are provided for stereo instruments (1/4ΠL/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.
