The Tascam MA-BT240 is a versatile 240-watt mixing amplifier designed for professional installations in retail stores, restaurants, offices, educational facilities, and other small to mid-sized commercial environments. Combining powerful Class-D amplification with flexible speaker compatibility, it supports both low-impedance loudspeakers (4/8 ohms) and high-impedance 70 V / 100 V distributed systems. With integrated Bluetooth 5.1 streaming, a built-in mixer with mic/line inputs and ducking function, and onboard EQ with high-pass filtering, the MA-BT240 delivers reliable performance and easy system integration. Its compact 1U half-rack design allows discreet desktop placement or rack mounting using the optional AK-RM05 kit, making it an ideal all-in-one solution for background music and paging applications.
