The DSPPA MP1000PIII is a classic 350W mixer amplifier with 3 mic inputs, 2 AUX inputs and 70V/100V constant-voltage outputs plus a low-impedance P1 output. It fits mosques, schools and meeting rooms that need clear announcements with MIC1 priority over background audio.
====
The DSPPA MP1000PIII is a 350W mixer amplifier built for straightforward public address work: three microphone inputs, two AUX inputs, and 70V/100V constant-voltage outputs that can drive long speaker lines. Mosques, schools and meeting rooms in Saudi Arabia use this kind of amplifier for sermons, morning assemblies and announcements, with recorded recitation or music playing underneath from an external source.
DSPPA MP1000PIII key specifications
The MP1000PIII is the top model of DSPPA's MP200PIII classical series, which also includes the MP200PIII (60W), MP300PIII (120W) and MP600PIII (250W). From the official datasheet:
- Rated output: 350W, with a rated power consumption of 650W.
- Outputs: P1 low impedance plus 70V and 100V constant voltage.
- Frequency response: 80Hz to 16kHz (±3dB).
- Signal-to-noise ratio: 74dB or better on the line input.
- Distortion: 1% or less at 1kHz.
Three mics with MIC1 priority
MIC1 sits on the front panel; MIC2 and MIC3 are on the back. MIC1 has priority, so when the imam or principal speaks, every other input drops automatically. A rear Mute control sets how far they drop, anywhere from 0 to -30dB, so announcements stay clear over recitation or background music.
AUX1 and AUX2 take a media player, a PC or a bell scheduler. The AUX output (700mV or more) passes the signal to a second amplifier when one building needs more power than a single unit gives.
100V lines for distributed speakers
With a 100V or 70V constant-voltage line you can hang many ceiling and horn speakers on one long cable and pick each speaker's wattage from its taps, as long as the total stays within 350W. The P1 output suits a few low-impedance speakers close to the rack. DSPPA notes that only one pair of output terminals should be used at a time.
Controls and protection
Each input has its own volume knob, and the master section offers bass (±10dB at 100Hz) and treble (±10dB at 10kHz). A 5-segment LED meter shows output level; DSPPA recommends setting levels so only the 4th and 5th LEDs flash, since a fully lit meter means overload distortion. Protection covers output short circuit with an alarm indicator, overload, DC output and an AC fuse.
Where the MP1000PIII fits in KSA
- Mosques: a priority mic for the imam, a second for the muezzin, indoor and outdoor speakers on one 100V line.
- Schools: morning radio broadcasts and class bells from a player on an AUX input.
- Meeting rooms and small event halls: three speaker mics with background audio.
- Warehouses and factories: staff paging over horn speakers spread across the site.
Installation notes
The unit measures 483 × 338 × 88 mm, weighs 13.4 kg net and runs on 220V/50Hz. Leave space behind the unit for the cooling fan vent.
MP1000PIII, MP1010U or MP600PIII?
The MP600PIII is the same design at 250W, drawing 500W and weighing 13 kg net. The MP1010U matches the 350W rating but adds six zones with individual volume, a USB/SD player, FM tuner, Bluetooth and a pre-announcement chime. Pick the MP1000PIII when all speakers play together and your music source is external; pick the MP1010U when different areas need different audio.
Frequently Asked Questions
How many speakers can the MP1000PIII drive?
On a 100V or 70V line, add up the tap wattage of every speaker; the total must stay within 350W, ideally with some headroom.
Does MIC1 override the music?
Yes. MIC1 on the front panel ducks all other inputs automatically, and the attenuation is adjustable from 0 to -30dB.
Does it have USB or Bluetooth playback?
The datasheet lists no built-in player. Connect a player or phone to an AUX input, or choose the MP1010U for built-in USB/SD, FM and Bluetooth.
