Biamp MA60 60W 1-Channel Mixing Amplifier

The MA60 is a half-rack, 60-watt mixing amplifier designed for professional audio installations that demand clear performance and ease of use. Its front-panel controls provide instant access to volume and microphone adjustments, making it simple for any operator to manage day-to-day audio needs. Equipped with four priority levels, the MA60 ensures critical announcements always take precedence, featuring a dedicated emergency input with mute-all functionality, a paging mic with contact closure and chime, a mic/line input with 48V phantom power, and two stereo line inputs for background music.

Built on efficient Class D amplifier technology, the MA60 delivers consistent, high-quality sound while minimizing energy consumption. Its fanless cooling design ensures quiet operation, making it suitable for noise-sensitive environments such as offices, classrooms, retail shops, and hospitality spaces. With support for both low-impedance (4Ω) and constant-voltage (70V/100V) speaker systems, the MA60 adapts to a wide range of installations. Additional features include auto-standby for energy savings, 24V priority output for system integration, and an internal universal power supply for global compatibility. Compact yet powerful, the MA60 is a versatile solution backed by a five-year warranty.
