Product Description

The unique Roland BA-55 provides self-contained, high-quality, and battery-powered sound reinforcement for any environment. It's solidly built yet lightweight, and comes bundled with a matching wireless microphone for public speaking, singing, and many other events. Use the Roland BA-55 as a small wireless PA system in school classrooms, business meetings, restaurants, weddings, intimate music venues, and more. In a cool and convenient twist, the Roland BA-55 contains an internal accelerometer sensor that automatically switches operation between stereo output (when positioned horizontally) and mono output (when positioned vertically). If you're speaking and need maximum power and projection, use the vertical mono mode. For wide musical spread, turn horizontal. It's that easy!

Roland BA-55 Features

- Portable design with high-quality sound for audiences up to 80 people
- SPL (sound pressure level) rated at a powerful 108 dB
- One 2.4 GHz wireless microphone included (DR-WM55); a second DR-WM55 can be purchased separately for simultaneous use
- Operates on 8 AA batteries or AC power (AC adaptor included)
- Onboard accelerometer sensor switches operation to stereo mode when positioned horizontally
- Two 6.5" (16 cm) high-performance speakers
- Three-channel built-in mixer with two-band EQ
- Echo/Reverb effect
- Built-in Anti-Feedback function
- Line Output for recording or expanding the system
- Integrated storage compartment for storing wireless microphones and accessories
- Auto Power Off function
- Compatible with Roland ST-A95 speaker stand

Easy to Use and Transport

With the Roland BA-55, ease of use is the name of the game. There's nothing complicated about it: just turn on the wireless microphone and/or plug in your instruments, set the volume to the desired level, and go. That's it! The Roland BA-55's automatic anti-feedback system blocks acoustic feedback without interrupting your audio. For easy transport, the Roland BA-55 has a convenient built-in storage compartment to house your wireless microphones and accessories.

Multi-Purpose PA

The Roland BA-55 lets you enjoy great sound anywhere, indoors or outdoors. Use batteries or the included AC adapter for the ultimate in convenience and flexibility-- For speech, position the BA-55 vertically and the internal accelerometer will automatically switch operation to mono mode for maximum sound projection. For music, place the BA-55 horizontally and it will automatically switch to stereo mode; this is perfect when using MP3/CD players at dance parties, etc., or any application where wide sound projection is desired.

Built-In Echo/Reverb

Onboard the BA-55 is an Echo/Reverb that sounds great and is easy to use, with a single knob that adjusts both the effect type and amount. When you turn the knob from the Off position to 12 o'clock, you activate a natural plate-reverb-type effect that adds a natural ambience to your voice and/or instruments. When you turn from the 12 o'clock position to maximum, you switch to a repetitive echo-type effect. The echo/ reverb can also be turned on and off from the included DR-WM55 wireless microphone for convenient remote control (see below).

Wireless Microphone Included

The Roland BA-55 package includes a high-quality wireless microphone (DR-WM55). Designed specifically for this system, the mic has Power On/Off and Echo On/Off switches. The Echo switch is linked to the Roland BA-55's Echo/Reverb effect, which lets you enable and disable it directly from the mic. This is a very handy feature, allowing the effect to be quickly turned off when speaking or making announcements, then easily switched back on for singing. zZounds is an authorized dealer of Roland products.

1. We offer the most flexible payment plans in the biz

zZounds offers a number of different installment payment plans that make it affordable and convenient for you to get the gear you really want today, without racking up risky credit card debt.

Other stores offer house credit cards that require you to fill out an application and pass a credit check--and, if you qualify, leave you vulnerable to exorbitant interest charges once the initial promotional period ends. zZounds payment plans are easy to get and simple to use; plus we'll never charge you interest!

2. We guarantee the lowest price

If we don't already have the lowest price, just send us a link to any legitimate competitor's offer, and we'll beat their price as long as we're not losing money on the deal.

To submit a request for a lower price, click "Seen it for less?" on any product page. We answer most lowest price requests within two hours. For extra peace of mind, you also have 30 days after your purchase to find a lower price; if you do, we'll refund the difference.

5. Our customer service is consistently rated the best

zZounds customer service is consistently rated at or near the top on every major comparison shopping website--probably because we only hire experienced musicians with outstanding customer service skills to work in our call center, and they don't work on commission. To us, this is our most meaningful measure of success. zZounds has served over a million customers since 1996, and they're the only critics whose reviews really matter to us.
