DSPPA 35W Amplifier | MP35UB
The DSPPA MP35UB is a 35W mini digital mixer amplifier in a 1.5U case, with built-in Bluetooth, FM and USB. It drives 70V / 100V constant-voltage speaker lines or 4-16 Ω speakers, and mixes 2 microphones and 2 line sources with separate volume controls.

Built-in Sources: Bluetooth, FM radio and a USB player are built in, so background music needs no extra source device. A mode key switches between Bluetooth, USB, AUX and FM.
Flexible Speaker Output: The output supports 70V and 100V constant voltage as well as 4-16 Ω constant resistance. You can use it with line-voltage PA speakers or with low-impedance speakers.
Microphone Inputs: MIC1 is a 6.3 mm jack on the front panel and MIC2 is an XLR input on the rear with 48V phantom power. Each microphone and line input has its own volume control, plus bass, treble and master volume.

Priority: The priority order is EMC/MIC1 over AUX1, AUX2 and MIC2. Announcements on MIC1 or the emergency input come through over the music.
Emergency Inputs: There are 2 EMC inputs (100V / 375mV) and 1 EMC output for connection to an emergency signal. The master volume does not change the EMC signal from the rear panel.
Remote Control: The amplifier can be controlled with an infrared remote controller.

Good to know
MIC2 and AUX2 share one input: a rear switch selects AUX2 or MIC2/phantom power. Turn the volume down or switch the unit off before using this switch.
When an external 100V emergency signal is used, the ground wires of the two devices must not be connected together (DSPPA datasheet).
The power output terminals must not be connected to ground directly or through other devices.
