Lightweight, Powerful, Portable PA

The versatile SA-300 is built to handle nearly any type of audio you throw at it: microphones, rhythm machines, keyboards, CD players, etc. With full-range, high-quality stereo 2.1 ch 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 stereo 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. At just 19kg (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. The top unit can even be mounted on a speaker stand for perfect placement.

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 behind at their back. This anti-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.
