Ready for Low- and High-Impedance Speaker Systems
The MA-BT240 supports both high-impedance and low-impedance speaker connections. With the ability to support 70-volt/100-voltspeaker systems as well as pro-audio speaker equipment, the MA-BT240 is ideal for practically any small-format commercial amplification application.
Reliable Class D Amplification
Highly efficient Class D amplification gives the MA-BT240 high output for its compact size. Delivering an impressive output of 120W x 2ch @ 4Ω/8Ω for low-impedance systems, and 240W x 1ch @ 100V/70V for high-impedance systems, the MA-BT240 delivers plenty of power for moderate commercial spaces.
Onboard Bluetooth® Receiver
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 wireless reception. You can also extend the antenna with commercially-available RP-SMA wire, allowing you to place it in the optimal position for your specific space.*
* Maximum extension possible is approximately 20mBuilt-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 indicator lights to help you optimize signal levels at a glance.
EQ and High Pass Filter on Output
The MA-BT240 makes it easy to optimize your audio for the acoustics of your space. The output features a dedicated high pass filter to avoid distortion with high-impedance systems, as well as Treble and Bass boost/cut controls to fine-tune the sonic response of your system. Output can also be switched between Stereo and Mono operation to adapt to your speaker system configuration.
Additional Features
External Volume Controllers Supported
The MA-BT240 is easy to install in commercial spaces wherever it’s practical, with support for external volume controllers to put system control where you need it.*
* External controller must conform to the control terminal specifications of the unit. Euro block 3.81mm pitch 3-pin (1: Vcc 5V/2: Control/3: GND)Mic Input with Paging Function
The MA-BT240 is ideal for schools and facilities that require broadcast calls and business communications. The Mic/Line input features a paging function that mutes all other inputs during announcements.
Line Output for Expanding Your Speaker System
A line output makes it easy to create additional zones for your system by cascading the MA-BT240 to other amplifiers.
