DSPPA 4x20W WiFi Music Amplifier with SD/ Bluetooth/ AUX/ AirPlay/DLNA/ DM858
The DSPPA DM858 is a wall-mounted smart music player with a 7-inch touch screen and a built-in 4-channel Hi-Fi digital amplifier (4 × 20 W into 8 Ω). It plays local music, internet music, internet radio, SD, Bluetooth and AUX sources, and connects by Wi-Fi or wired network.
7-inch touch screen. A 7-inch TFT IPS-level capacitive touch screen gives full-screen, graphical control. Choosing a source, a song or the volume works like using a phone.

Network and phone streaming. The DM858 supports Wi-Fi, wired network (RJ45 10/100M) and Bluetooth 4.0. DSPPA lists AirPlay and DLNA push from a phone, plus internet music and internet radio.
Two zones from one unit. Its 4-channel output with dual-zone control lets two areas be controlled separately, each with its own volume. For example, a living room and a kitchen can play at different levels.
Sound tuning. A built-in SIGMA DSP audio processor with a 10-band equalizer adjusts the sound to the room. It supports MP3, WAV and FLAC files.

Schedules and automation. Built-in schedule and automatic calibration functions play songs by week and date with adjustable volume. 2 I/O inputs, 2 relay outputs and RS485 allow links to other systems.
Intercom between devices. A built-in microphone lets several devices on the same LAN make intercom calls to each other. The system runs on a 64-bit quad-core Cortex-A53 CPU with 4K H.265 hardware decoding.
Good to know
- Power input is 100-240 V, 50/60 Hz.
- The speaker outputs are rated 4 × 20 W into 8 Ω.
