Designed to make live sound portable and easy, the RL112A is a 2-way active loudspeaker that features a massive 800 watts of power from an advanced Class D amplifier, which keeps the overall system weight under 35 pounds. On the road or at the corner coffeehouse, the RL112A is ideal for DJs, lectures, meetings, events, as well as for the singer/songwriter or acoustic duo. Class D amplification provides ample power from a lightweight and efficient chassis. The unique bi-amp design hosts two separate power amps, one to drive the massive low end, and one to attain warm, smooth highs. Together, the RL112A can produce 800 Watts of Peak Power - delivering plenty of headroom in the audio signal to prevent distortion. Internal circuitry provides thermal and overload protection, a compressor, plus an optical-based limiter keeps everything running and sounding smooth. Tight, punchy bass emanates from a 12 inch. extended range low frequency driver; the generous 2 inch. voice coil offers higher efficiency and maximizes heat dispersion. Up top is a 1 inch. high frequency driver equipped with a 1 inch. voice coil. The use of rare-earth neodymium magnets increases efficiency, providing improved clarity and intelligibility. The molded 90-degree x 60-degree high frequency horn delivers excellent high-frequency dispersion and coverage. Channel 1 of the RL112A onboard mixer features an XLR-1/4 inch. combo jack - complete with a gain-matching mic/line switch - to accommodate nearly any input source. Channel 2 is dedicated to receiving the signal from a Samson XPD wireless microphone (not included), making it the perfect choice for conferences, lectures, rallies, fitness classes, and entertaining. Individual level knobs set the perfect balance. The Mix Out jack (XLR) passes the combined signal along to additional equipment as you buildout your system. Switching on the Contour (EQ) circuit can enhance the sound in challenging venues. Impact-resistant polypropylene cabinets equipped with perforated metal grilles provided added protection to the RL112A speakers themselves. And its versatile design invites either vertical (front of house) or horizontal (monitor) usage. Three easy-carry handles provide easy transport and placement. A convenient 1-3/8 inch. pole-mount socket is built right in.
