DSPPA 2x30W Mini Digital Amplifier with USB & Bluetooth | Mini60
The DSPPA Mini60 is a small 2 × 30W stereo digital amplifier with Bluetooth, USB/SD playback, microphone inputs and a stereo line input and output. It runs on a 12–24V DC supply and is built around an ARM-based controller and an energy-efficient digital power amplifier circuit.
Several music sources: Music can come from Bluetooth, a USB flash drive (DSPPA states USB disks under 32 GB), an SD card, or a wired source on the stereo line input. The MODE key switches between Bluetooth, USB and line-input (AUX) mode, and an inserted SD card starts playing automatically.

Microphone and recording: There is a 6.35 mm microphone input on the front and another on the rear. In AUX mode the REC key records the line or microphone signal to the USB drive or SD card as MP3; the microphone volume can be adjusted only in AUX mode.
Line output and speaker terminals: A line output can feed an external power amplifier. Speakers connect through a phoenix-type terminal block, and the output accepts 4–16 Ω loudspeakers; DSPPA states up to 8 DSPPA 8 Ω ceiling speakers can be connected in two groups.
Protection and housing: The stereo digital amplifier has protection against overheating, output overload and short circuit. The casing is aluminium alloy, small and robust.

Who it's for / Works with
DSPPA states that the Mini60 suits small broadcast systems, background music in small supermarkets and public address in classrooms.
