DSPPA 120W 3 Mic & 2 AUX Mixing Amplifier | MP300PIII
The DSPPA MP300PIII is a 120W mixer amplifier for public address (PA) systems. It combines three microphone inputs and two auxiliary inputs with its own power amplifier, and drives speakers on 70V or 100V constant-voltage lines or from the P1 low-impedance output. It belongs to DSPPA's MP200PIII series (MP200PIII, MP300PIII, MP600PIII and MP1000PIII), which share the same inputs, controls and chassis size and differ in output power, power consumption and weight.
Three microphones and two music sources: The amplifier has three microphone inputs, two auxiliary (AUX) line inputs and one AUX output. MIC1 is on the front panel, MIC2 and MIC3 are on the rear. Each input has its own volume knob, so you can balance a paging microphone against background music from a player.
70V / 100V line or low-impedance output: The rated output power is 120W. You can connect speakers to the 70V or 100V constant-voltage terminals or use the P1 low-impedance output. DSPPA notes that only one pair of the four output terminals (COM, P1, 70V, 100V) should be used at a time.
MIC1 priority for announcements: MIC1 is the priority input. When someone speaks on MIC1, it overrides the other inputs, and the mute level of the other sources can be set from 0 to -30 dB with the mute control on the rear panel. This lets announcements be heard clearly over the music.
Tone control and level meter: Bass (±10 dB at 100 Hz) and treble (±10 dB at 10 kHz) controls let you adjust the sound to the room. A 5-segment LED level meter on the front shows the output level; if all five LEDs stay lit, the output is overloading and the volume knobs should be turned down until the 4th and 5th LEDs flash.
Protection: The amplifier has AC fuse, DC output, overload and short-circuit protection, and the output short-circuit protection comes with an alarm indication. The AUX output (≥700 mV) can feed another amplifier when you need more power.
Who it's for / Works with
DSPPA states that the MP200PIII series is meant for public address and public broadcasting in places such as schools, conference rooms and commercial spaces. It works with 70V/100V PA speakers and with microphones and line-level music sources.
Good to know
- Power supply is AC 220V / 50Hz only.
- Rated power consumption is 250W.
- Use only one pair of output terminals at a time (P1, 70V or 100V with COM).
- Microphones, speakers and cables are not included in this listing.
