The ALF-60W-UB is a versatile 60W Class-D mixer amplifier designed for small commercial sound installations where reliable amplification, paging, and built-in media playback are required. Its compact design combines a mixer amplifier with Bluetooth, USB, FM radio, and MP3 playback, providing convenient options for both live sources and background music.
The amplifier supports 70V and 100V distributed speaker systems as well as 4-16Ω low-impedance speakers, making it suitable for a variety of commercial audio setups. It includes two microphone inputs, an emergency input, two line inputs, and a line output, with individual controls for the microphone channels, auxiliary sources, bass, treble, and master volume. The front-panel microphone input includes a priority function, while the rear balanced microphone input provides phantom power for compatible microphones.
Designed with installation flexibility and dependable operation in mind, the unit supports AC 100-240V power and 24V backup power. Priority operation is configured as EMC > MIC1 > Others, while built-in protection helps safeguard the amplifier against short circuits, clipping, overload, and excessive temperature. LED indicators provide quick status monitoring for power, signal, clipping, and protection, making it a practical choice for classrooms, retail stores, restaurants, cafés, and other small commercial spaces.
