DSPPA 250W Mini Digital Mixer Amplifier with USB & Bluetooth | MP250UB
The DSPPA MP250UB is a 250W mini digital mixer amplifier in a 1.5U chassis, with a built-in USB player, FM radio and Bluetooth. It drives 70V/100V constant-voltage speaker lines or 4–16 Ω speakers, and has two microphone inputs, two line inputs and emergency (EMC) inputs for PA systems.
Built-in music sources: A USB port on the front panel plays music from a flash drive, and the FM tuner and Bluetooth add two more sources. The MODE key switches between Bluetooth, USB, AUX and FM, and the amplifier can also be operated with an infrared remote control.
Microphones with priority: MIC1 is a 6.3 mm jack on the front panel and MIC2 is a balanced XLR input on the rear with 24V phantom power (MIC2 shares a selector switch with AUX2). The priority order is EMC/MIC1 > AUX1/AUX2/MIC2, so an announcement on MIC1 takes over from the music.
Emergency (EMC) input: Two EMC inputs (100V and 375 mV level) and one EMC output let the amplifier carry emergency messages from another system. The master volume does not affect the EMC signal, which has its own volume control.
Speaker outputs and controls: Speakers connect to the 70V or 100V constant-voltage terminals or to the 4–16 Ω output. Each microphone and line input has its own volume control, with master volume plus bass and treble (10 dB ±2).
Backup power: A DC 24V backup power input on the rear panel keeps the amplifier running from a backup supply.
Who it's for / Works with
PA speakers on 70V/100V lines or 4–16 Ω speakers, microphones (MIC2 offers phantom power), phones over Bluetooth and USB flash drives.
Good to know
- Power supply: AC 110–120V or AC 220–240V, 50/60Hz, selected with a switch on the rear panel; set it to match your mains before use.
- MIC2 and AUX2 share one selector switch: use one or the other. Turn the volume down before using the switch.
- When using the 100V EMC input, the ground wires of the two devices must not be connected together.
- Speakers and microphones are not included.
