DSPPA 120W 6 Zones USB/SD/FM Mixer Amplifier /MP212U
The DSPPA MP212U is a 120 W public address mixer amplifier with six speaker zones on a 100 V line. It combines a built-in MP3 player (USB and SD), an FM tuner, two microphone inputs and three line inputs in one unit, so a small PA system can run from a single box.
Six 100 V zones. The amplifier feeds six speaker zones at a constant 100 V, and each zone has its own on/off button plus an ALL ON button. You can play music or announcements in selected areas only, for example the shop floor but not the office.
Built-in music sources. USB and SD card playback and an FM tuner (87.5 to 108.0 MHz) are built in, with their own volume control. Background music does not need a separate player.
Microphone priority. Mic 1 on the front panel has priority: when it is used, the other inputs are muted with 0 to -30 dB attenuation. Announcements are heard clearly over the music without touching the volume knobs.
Inputs and tone control. There are 2 microphone inputs and 3 line inputs, each with its own volume knob, plus bass (±12 dB at 100 Hz) and treble (±12 dB at 10 kHz) controls. A 1 line (AUX) output at 0 dBV can feed another amplifier.
Monitoring and protection. A 5-unit LED level meter shows the output level, so you can see when the sound starts to distort. Protection covers the AC fuse, DC voltage, overload and output short circuit.
Who it's for / Works with
DSPPA lists the MP212U for small public address systems such as supermarkets, classrooms, banks, churches, schools, hotels, restaurants, theme centres and shopping centres. It drives 100 V line speakers.
Good to know
- The speaker output is 100 V line; DSPPA does not list a low-impedance (ohm) output for this model.
- Power supply is AC 220-240 V, 50/60 Hz.
- Mic 1 on the front is a 1/4-inch jack for unbalanced microphones (30-600 Ω).
