Stage Right™ by Monoprice™ D1 Battery-Powered Portable PA Speaker System Class D amp with Bluetooth® streaming and built-in mp3 player Imagine being able to perform anywhere you want to, regardless of the access to an AC outlet. Let's face it, outdoor performances and parties are a part of our lifestyle, now more than ever. The same could be said of presenting and public speaking. Truly, all the world's a stage. The D1 Battery-Powered Portable PA Speaker System is a lightweight and versatile system that delivers an impressive 60 watts of power, thanks to the efficient Class D amplifier design. Whether you're DJing, singing, playing an instrument, or doing all three at the same time, this all-in-one battery-powered system can handle all your audio needs. Having your music or spoken word heard anytime, anywhere, and on the fly has never been this simple. BATTERY POWERED The built-in rechargeable Lithium-ion battery array has a total capacity of 7800mAh, which gives you up to 6 hours of playback time. CLASS D POWER The D1 Battery-Powered Portable PA Speaker System has an efficient Class D amplifier, which produces 60 watts (RMS) of power. It features a 60Hz ~ 18kHz frequency response and can pump out an impressive 102dB sound pressure level (SPL). TRUEWIRELESS STEREO If you're looking for a full stereo solution from a portable, battery-powered PA, this system has you covered. The TrueWireless™ Stereo (TWS) feature allows you to sync a pair of D1 or D3 PRO powered speakers with the touch of a button to produce a true left/right stereo pair. JAM TO YOUR FAVORITE TRACKS The system features a Bluetooth® radio, so you can jam or sing along with karaoke or studio tracks streamed wirelessly from your smartphone or laptop. It also features a built-in mp3 player, allowing you to load up an SD™ card or USB flash drive with your favorite mp3s and control playback using the nifty playback controls. 3-CHANNEL MIXER Individual volume controls for the two XLR inputs and the built-in mp3 player allow you to find the perfect mix for your performance, while the separate master volume control allows you to increase or decrease the overall output level of your mix. The Bass and Treble controls give you additional control over the tone of your mix. TWO MICS OR INSTRUMENTS The two XLR inputs can be set to accept either microphone or instrument level inputs, so can connect a pair of mics or a pair of instruments for your performance. The XLR output sends your post-mix signal to a second D1 or D3 PRO PA speaker or to a multichannel mixing board to make your performance part of a larger audio presentation. THE ULTIMATE ROAD WARRIOR The enclosure's design allows you to place or mount it in a variety of ways to accommodate your various needs and for stages or venues of all shapes and sizes. Mount it to a PA tripod for enhanced projection over a large area, place it horizontally on the ground to serve as a stage monitor, or place it on the ground to project your performance to a smaller crowd. The rugged polypropylene construction ensures years of use under the grueling conditions of the road.
