Biamp MA120 19" Mixing Amplifier

What Is the Biamp MA120 19" Mixing Amplifier?
The Biamp MA120 is a versatile 19" mixing amplifier designed for commercial audio applications that require seamless sound distribution and priority-based audio management. With 120 watts of continuous power, this amplifier supports both 4Ω and 70V/100V speaker systems, making it suitable for paging, background music, and emergency communication. Its robust design, multiple inputs, and intuitive controls make it an excellent choice for professional AV installations in corporate offices, retail spaces, educational institutions, and public venues.

Powerful and Flexible Audio Amplification
Designed for reliability, the MA120 delivers 120 watts of continuous power, ensuring consistent audio performance in various environments. It operates in both low-impedance (4Ω) and high-impedance (70V/100V) modes, allowing for flexible speaker configurations. Whether you need distributed sound for a large facility or high-powered amplification for specific zones, this mixing amplifier provides the power and clarity required for demanding audio applications.

Multiple Inputs for Comprehensive Sound Management
The Biamp MA120 features two mic/line inputs with 48V phantom power, making it compatible with both dynamic and condenser microphones. Additionally, it includes four stereo line inputs that can be mixed and routed for background music or other audio sources. The dedicated paging microphone input with a contact closure and built-in chime ensures clear, intelligible announcements, making this amplifier an excellent choice for environments that require prioritized voice communication.

Intelligent Priority System for Audio Control
A four-level priority system allows the MA120 to dynamically manage multiple audio sources, ensuring that critical announcements take precedence over background music or other audio inputs. The emergency input function includes a "mute all" switch, instantly silencing all other channels for immediate message delivery. The 24V priority output further enhances system control by overriding local volume settings when necessary, making it ideal for emergency broadcast applications.

Efficient, Fanless Design for Quiet Operation
Unlike many amplifiers that rely on cooling fans, the MA120 operates without one, ensuring silent operation in noise-sensitive environments. This fanless design reduces maintenance concerns while providing reliable heat dissipation for long-term performance. Whether installed in an AV rack or a standalone setup, the amplifier remains cool and efficient, making it perfect for conference rooms, auditoriums, and other professional spaces.

Rack Mountable and Built for Professional Installations
With a 2RU form factor, the MA120 fits seamlessly into standard AV racks for easy integration into new or existing audio systems. The intuitive front and rear panels provide quick access to input selection, volume control, and priority settings, ensuring simple operation for both technicians and end users. Built to meet CE, UL, and RoHS compliance standards, this amplifier is designed for high-performance commercial audio installations.
