The HDL MZBOX-A50B.30 HomePlay Network Player is a multi-room audio streamer with a built-in Class D amplifier (rated 32 W + 32 W at 8 Ω). It plays music from online services, NAS (DLNA), USB, Bluetooth, line-in, and mobile devices — controlled via the HDL ON iOS/Android app or HDL wall interfaces such as the KNX Granite Display.

HomePlay supports simultaneous multi-source, multi-room streaming and is compatible with HDL room scenes and sequences, so lighting, shading, and music can be triggered together. High-resolution formats include FLAC, ALAC, APE, and WAV alongside MP3, AAC, and WMA.

Applications and System Integration

• Hotel and residential: Centralized music with app control for guests and owners.

Choosing HDL Audio

The MZBOX-A50B.30 is HDL's amplified HomePlay streamer — one box for streaming, amplification, and scene integration. It requires a suitable 802.11 a/b/g/n Wi-Fi router and ventilation. For KNX-only bus devices (sensors, actuators, PSU), see the M/P960.1 and actuator range.
