Pure Resonance MA30BT Mixer Amplifier 30W Bluetooth 70V/100V Paging

Compact Paging and Background Music Control in One Amplifier

The Pure Resonance Audio MA30BT is a compact 30W mixer amplifier designed for background music, paging, announcements, and small distributed-audio systems. It supports 70V and 100V speaker systems as well as conventional 4-ohm, 8-ohm, and 16-ohm speaker loads.

Best Uses

• Offices and reception areas
• Retail stores and cafés
• Classrooms and waiting rooms
• Small restaurants and hospitality spaces
• Background music and paging systems

Speaker Output Options

• Rated output: 30W
• 70V distributed-speaker output
• 100V distributed-speaker output
• 4-ohm, 8-ohm, and 16-ohm low-impedance outputs

For 70V or 100V systems, add the selected wattage tap of every connected speaker and keep the total below the amplifier's 30W rating. Leaving approximately 20% headroom is a practical design target, so a total speaker load around 24W or less is preferable.

Do not connect 70V or 100V speakers and low-impedance speakers to different amplifier outputs at the same time unless the manufacturer specifically approves that configuration.

Bluetooth and Media Playback

• Built-in Bluetooth audio streaming
• USB media playback
• TF card playback
• Built-in FM radio
• Included IR remote control

Bluetooth is used for audio streaming from compatible phones, tablets, and computers. It is not Wi-Fi streaming, app-based multi-room audio, AirPlay, or network audio.

The manufacturer notes that FM reception can vary with location and interference and does not recommend FM radio as the primary audio source for critical installations.

Microphone and Line Inputs

• MIC 1 balanced XLR input with phantom power
• MIC 2 and MIC 3 switchable mic/line 1/4-inch inputs
• Two stereo RCA line inputs
• RCA line output
• Front-panel source, microphone, bass, treble, and master controls

The MA30BT can mix paging microphones with music sources, making it suitable for systems where announcements and background audio share the same speakers.

Additional Connections

The amplifier supports telephone paging and Music On Hold functionality as part of its commercial audio feature set. Confirm telephone-system compatibility and wiring requirements before installation.

When to Choose Another Model

Choose a higher-powered mixer amplifier if the total 70V or 100V speaker taps exceed the MA30BT's available output. Choose a separate stereo amplifier or receiver if you need true left/right stereo speaker playback rather than a mono distributed-audio system.
