7" Smart Tuya Panel with Background Music Amplifier 4×20W | DSPPA DM938T
The DSPPA DM938T is a 7-inch smart background music amplifier for the wall, with 4 × 20 W music power (4 × 10 W output power) into 8 Ω speakers. It runs Android 8.1 on a quad-core processor with 2 GB RAM and 8 GB ROM, and DSPPA lists Tuya support for this model.
7-inch HD touch screen. A 7-inch TFT digital HD screen (1024 × 600) with multi-point capacitive touch controls the music and functions. Operation is similar to a tablet.

Music from phones. DLNA, AirPlay and Qplay let you push music, videos, pictures, files and apps from a phone to the panel. Bluetooth and Wi-Fi audio push are also supported.
Four speakers, two zones. It has 4 speaker outputs with 2-zone volume control. Each output connects an 8 Ω 10 W constant-resistance ceiling speaker, so two areas can play at different volumes.

Multi-zone and intercom. Several panels on the same LAN can be controlled as multiple zones and used for intercom, using the built-in digital microphone. Timed power on and off is also supported.
More sources and control. A TF card slot and a USB 2.0 port (each up to 32 GB) play local music, and there is one AUX audio input and one audio output. External systems can control the panel through RS485.
