The TOA Amplifier A-2120 delivers dependable audio performance for public address and background music systems. Designed for commercial environments, this TOA Amplifier offers a solid 120W output that supports clear and consistent sound across a wide coverage area. As a result, it is well-suited for offices, schools, mosques, retail spaces, and industrial facilities.
Because flexibility matters in professional installations, the amplifier includes three microphone inputs and two AUX inputs, allowing multiple audio sources to be used at the same time. MIC 1 also provides phantom power, making it compatible with condenser microphones for higher audio clarity. Furthermore, its built-in bass and treble controls help users fine-tune sound according to room acoustics.
In addition to its practical connectivity, the TOA Amplifier A-2120 features a priority muting function. This automatically lowers background audio when an announcement is made, which ensures important messages remain clear and easy to hear. The front panel is straightforward and intuitive, enabling quick adjustments even during live operation.
Durability is another advantage of this model. Its steel chassis and heat-efficient design allow stable performance during long hours of use. Moreover, the amplifier supports 70V, 100V, and low-impedance speaker outputs, giving installers the flexibility to integrate it into both small and large PA systems.
With its combination of power, reliability, and ease of use, the TOA Amplifier A-2120 becomes a strong choice for anyone requiring consistent audio distribution in commercial spaces.
