A50+ WiFi & Bluetooth Amplifier — Airplay, Subwoofer Output, Multi-Area Synchronized Audio

Compact yet powerful, the A50+ is a Wi‑Fi and Bluetooth capable Class D digital amplifier with Airplay support, a dedicated subwoofer output and multi-area synchronized audio for multiroom setups. Control options include the 4STREAM app (available for iOS and Android) which lets you choose your music source, manage playback, adjust EQ, switch between multi-room or independent zone playback, load presets, set alarms, configure Wi‑Fi and perform firmware updates. Each unit also offers direct browser control — simply enter the device IP to access its web interface. For multiroom use, multiple A50+ units on the same network can stream in sync or operate as separate zones, all controllable from your phone. Audio performance is driven by the Class D amplifier design, delivering 50 W per channel at 24 V/4 ohms and 35 W at 24 V/8 ohms, and an internal DAC capable of decoding up to 24 bit/192 kHz for detailed, high-resolution sound.
