Powerful Background Music, Announcements and More
Sound Reinforcement the Easy Way

The MA-BT240 is a versatile mixing amplifier designed for sound distribution, presentations and announcements in smaller commercial environments.

Combining amplification for both low- and high-impedance loudspeaker systems with a microphone input, two line-level inputs and a Bluetooth receiver for wireless audio streaming, it is an ideal choice for restaurants, retail stores, institutions, waiting rooms and similar locations.

Ready for a Pair of Stereo Loudspeakers or Distributed Speaker Systems

The MA-BT240 can drive both standard low-impedance loudspeakers and high-impedance 70-volt / 100-volt distributed loudspeaker systems. This makes it an ideal choice for virtually any small-format commercial sound reinforcement system.

Reliable Class-D Amplification

Highly efficient Class-D amplification gives the MA-BT240 high output for its compact size. With an impressive output power of 240 watts (2 × 120 W at 4/8 Ω for low-impedance loudspeakers or 1 × 240 W at 100 V / 70 V for distributed loudspeaker systems), the MA-BT240 provides plenty of power for medium-sized commercial spaces.

Onboard Bluetooth Receiver for Wireless Streaming

The MA-BT240 makes it simple to stream music wirelessly with its built-in Bluetooth receiver. The Bluetooth antenna is mounted on the front panel for stable reception. You can also extend* the antenna with a commercially-available PR-SMA cable, allowing you to place it in the optimal position for your specific space.

* Maximum possible extension is approximately 20 metres

Built-in Mixer with Mic and Line Inputs

In addition to Bluetooth connectivity, the MA-BT240 is equipped with a switchable Mic/Line input with ducking function, as well as two additional line inputs for external audio players. Each input can be mixed with dedicated knobs on the front panel, with Signal and Peak indicators to help you optimise signal levels at a glance.

EQ and High-Pass Filter on Output

The MA-BT240 makes it easy to optimise your audio for the acoustics of your location. The output has a dedicated high-pass filter to prevent distortion in high-impedance systems, as well as treble and bass controls to fine-tune the sonic response of your setup. The output can also be switched between stereo and mono operation to match the configuration of your loudspeaker system.

Compact 1U Half-Rack Size

With its compact half-rack size, the MA-BT240 saves space even when simply placed on a desktop. With the optional AK-RM05 rack kit (sold separately), the MA-BT240 can be mounted in any standard equipment rack.
