The Biamp MA30 is a compact 30W single-channel mixing amplifier designed for commercial audio systems that need paging, background music, microphone inputs, and priority audio routing in a space-efficient chassis.
With support for 4Ω low-impedance and 70V/100V constant-voltage speaker systems, the MA30 can be used in a variety of commercial sound installations. Its four-level priority system provides dedicated handling for emergency announcements, paging, microphone sources, and background music.
The Class-D, fanless amplifier design provides efficient operation without the noise of a cooling fan, making the MA30 well suited for conference rooms, offices, retail spaces, houses of worship, and other environments where quiet operation is important.
Flexible Audio Mixing and Priority Routing
The MA30 provides multiple inputs for combining paging, microphone, and background music sources while maintaining priority control over the system.
Key input functions include:
-
Emergency input with mute-all override
-
Paging microphone input with contact closure and chime
-
Mic/line input with +48V phantom power
-
Two stereo line inputs, mono-summed
-
Four levels of audio priority
-
Front and rear panel controls
This configuration allows the MA30 to handle everyday program audio while giving higher-priority sources control when announcements or emergency messages are required.
30W Output for Commercial Distributed Audio
The MA30 provides 30W of continuous single-channel amplification and supports both traditional low-impedance speakers and commercial constant-voltage systems.
Output Options
-
30W continuous output
-
4Ω low-impedance operation
-
70V operation
-
100V operation
-
Class-D amplifier topology
This flexibility makes the MA30 suitable for smaller distributed audio systems where a compact amplifier is needed without the additional capacity of a larger commercial mixing amplifier.
Paging and Emergency Audio
A dedicated emergency input with mute-all override allows emergency audio to take priority over other connected sources.
The paging microphone input provides contact closure and chime functionality, making it useful for commercial paging applications where announcements need to override background music.
The MA30 can therefore serve as the central amplifier for applications combining:
-
Background music
-
Paging
-
Microphone announcements
-
Emergency announcements
-
Commercial distributed audio
Microphone and Line Inputs
The MA30 provides flexible connectivity for both microphone and program sources.
The microphone/line input supports +48V phantom power, allowing compatible condenser microphones to be used without requiring a separate phantom-power supply.
Two stereo line inputs can also be mono-summed, allowing common music sources to be incorporated into a single-channel commercial sound system.
Fanless Class-D Design
The MA30 uses an efficient Class-D amplifier design with fanless operation. Eliminating a cooling fan helps reduce unwanted mechanical noise, which is particularly useful when the amplifier is installed near occupants.
An auto-standby function also helps reduce power consumption when the system is not actively being used.
Compact Installation
The MA30 is designed as a half-rack-width amplifier, making it a practical choice when equipment-room or rack space is limited.
It can be used in applications where a smaller amplifier is preferable to a full-size commercial mixing amplifier.
Typical applications include:
-
Conference rooms
-
Small meeting rooms
-
Retail stores
-
Restaurants
-
Houses of worship
-
Offices
-
Classrooms
-
Background music systems
-
Small paging systems

Why Choose the Biamp MA30?
The Biamp MA30 is a practical choice when a commercial audio system needs a combination of mixing, paging, priority routing, and amplification without requiring a high-power amplifier.
Its support for 4Ω, 70V, and 100V systems gives installers flexibility, while the compact, fanless design makes it suitable for smaller installations and spaces where quiet operation matters.
