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 offering a stereo and mic input. Vocalists can sing with 

confidence thanks to the SA-300’s anti-feedback function and dedicated 

vocal effects. Also onboard are stereo reverb and low-boost features.

Unlike conventional PA systems, the SA-300 can be placed 

behind the player or singer, thanks to its 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. The anti-feedback feature can be activated 

from the unit or optional footswitch.

All-In-One Solution

Advanced Anti-Feedback Function

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.

Sound Control Features

Each of the SA-300’s four channels offers XLR inputs (ch. 3 and 4 are 

phantom powered). In addition, 1/4-inch input jacks (L, R) are provided 

for each channel; channels 3 and 4 include RCA input jacks (L, R). Also 

onboard: 1/4-inch outputs and XLR connectors with dedicated ground 

switches. The Stereo Link jack lets you cascade two SA-300s, giving you 

a total of eight channels plus the ability to position the two units on 

opposing sides of the stage.
