Specifications

The versatile SA-300 is built to handle any type of audio source you plug into it: microphones, rhythm machines, keyboards, CD players, etc. With full-range, high-quality stereo 2.1 channel sound, sturdy construction, built-in effects, advanced anti-feedback control, two-piece transportability, loads of I/O options, and more, the SA-300 is a traveling musician’s dream.

Four-channel portable stereo PA system
Lightweight (easy to carry) yet powerful
Advanced anti-feedback function
Separate reverb effects for each channel (plus delay for ch 1 and ch 2)
Low Boost switch for powerful low-end
Wide Switch for big stereo effect, plus 3-band EQ
Vocal Enhancer for clear, strong vocals
Detachable woofer unit for easy transport
All-In-One Solution
Lightweight yet feature-packed, the SA-300 is powered by an internal 350W amplifier, which drives a pair of high-performance 6.5-inch speakers; a 200W amp drives the 12-inch woofer unit for booming bottom-end support. A 4-channel mixer is built in, with each channel equipped with a stereo and mic input (channels 3 and 4 are phantom powered). Vocalists can sing with confidence thanks to the SA-300’s anti-feedback function and dedicated vocal effects. Also included is a Low-Boost switch for extra beef, plus stereo reverb for a rich, ambient sound.

Transport Friendly
For the utmost in traveling convenience, the SA-300 can be detached into two easy-to-carry components (each with handles), rather than one cumbersome, heavy box. Weighing in at approximately 50 lbs (combined weight), the SA-300 is the lightest portable PA in its class. As an option, the top unit can be used independent of the bass unit; it self-adjusts to function as a standalone stereo speaker unit.

Sound Control Features
Each of the SA-300’s four channels is equipped with an independently adjustable reverb effect. For channels 1 and 2, you can switch to a delay effect, and also add a Voice Enhancer to give your vocals more definition and clarity. Adjust and enhance the overall sound with the 3- band EQ knobs, use the Low Boost feature to inject some serious bottom- end power into your sound, and flip the Wide switch for a big stereo sound. Unlike conventional PA systems, SA-300 can be placed behind the player or singer, thanks to the onboard anti-feedback function. The SA-300 avoids feedback before it occurs, so singers can roam the stage with confidence, and with 350 watts of powerful sound at their back. This feedback feature can be activated from the unit, or from an optional footswitch (BOSS FS-5U) for hands-free operation.

Versatile I/O
No matter what instrument, microphone, or musical device you wish to use, the SA-300 can accommodate it. Each of its four channels accepts microphones via XLR inputs, with channels 3 and 4 offering phantom power. In addition, 1/4-inch phone input jacks (L, R) are provided for each channel, and channels 3 and 4 include RCA input (L, R) jacks. If you wish to use additional sound-reinforcement gear, the SA-300 offers 1/4-inch phone outputs and XLR connectors with dedicated ground switches for reducing hum noise. The Stereo Link jack lets you cascade two SA-300s, giving you a total of eight simultaneous channels plus the ability to position the two units on opposing sides of the stage.
