• 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 6.5Œ stereo 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.
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.
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.
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 1/4Œ jacks), two stereo channels are provided for stereo instruments (1/4Œ L/R jacks), and a stereo Aux input channel is provided for CD players and other devices (RCA and TRS jacks).
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.
