Main Features
The SA-300 is a lightweight yet powerful stage amp, which functions as a combo amp while featuring full 2.1-channel stereo
compatibility.
High Power
This combo amp has an output of 350 W (75 W + 75 W stereo, 200 W subwoofer).
4-Channel/Full Stereo Input Compatibility
The SA-300 features four input channels, all of which handle stereo input. Additionally, all are compatible with microphones
as well as line-level equipment. The SA-300 also provides phantom power for two mic inputs.
Simple Setup
The mixer, amp, and speakers are integrated into a single unit, eliminating the need for complicated and bothersome cable
connections.
Light, Compact, and Extremely Portable
All speakers are newly developed custom speakers built from new materials. Midrange and high-frequency sounds are
played through a 6.5” coaxial 2-way speaker, with a 12” woofer handling the low end. Both speakers succeed in reducing
weight to half that of previous models (as compared with previous Roland products). Development of improved, more
powerful magnets than in previous products has resulted in greater efficiency and quick response. Additionally, use of Class-
D power amps for high energy conversion efficiency and switching power supplies reduces generation of unnecessary heat,
thus permitting use of smaller, lighter power transformers and heat sinks.
Plus, the cabinet separates into compact upper and lower units for easy carrying.
Newly Developed Anti-Feedback Function (Pre-Detection)
Conventional monitor amps have always presented the risk of feedback when the amp is placed directly behind the
performer, so these amps are not set up directly behind vocalists (or MCs). The SA-300’s newly developed pre-detecting anti-
feedback function resolves this problem.
Wide Variety of Effects
The SA-300 features great effects such as a voice enhancer, reverb, and an easy-to-operate delay for use with microphones.
You also get 3-band EQ, a “Wide” function, which provides expanded presence; and a low boost function, which emphasizes
the extreme low end.
Foot Control Function
You can connect an expression pedal and use the pedal to control the volume. You can also connect a foot switch to switch
the muting and effects on and off.
New Stereo Link Function
The Stereo Link function allows you to connect two SA-300s together and use them as independent left and right stereo
speakers. What’s more, you can use the input channels on both SA-300s, giving up to eight inputs.
