Product Description

DSPPA production line covers 4 types of amplifiers: preamplifier, power amplifier and mixer amplifier, digital amplifier. 
Preamplifier, it is an electronic amplifier that prepares a small electrical signal for further amplification or processing. It is the audio mixer for different types of audio s, which is very common in Public Addressing System. 
Power Amplifier. There are 2 types of power amplifiers in DSPPA production line: analog power amplifier and digital power amplifier. The power amplifier has 2 types of speaker outputs: low impedance (resistance fixed) output at ***6Ω) and high impedance (voltage fixed) output at *0V/**0V. 
Mixer Amplifier. DSPPA has various series of mixer amplifiers covering from *5W to **0W. Mixer amplifiers not only have the functions of preamplifiers and power amplifiers, but sometimes also have zone control function. They may have microphone s in 6.*5mm/XLR/combo sockets, auxiliary line s in RCA/combo sockets, MP3 via SD card/USB/Bluetooth, Tuner of AM/FM, built-in Chime. Some also have EMC and TEL . They support local paging, and some support remote paging CAT*5 cable, like MP**2 series, MP**2 Series. Some models have zones control function, such as MP**2 with 4x4 matrix function, MP**2 Series and MP**0U series with 6 zones control function.
Digital Amplifier. DSPPA digital pa amplifiers include multichannel digital power amplifier and digital mixer amplifier with audio source. Comparing to analog amplifier, digital amplifier is more efficient in power saving, efficiency up to *5% or more. And the amplifier module is more compact and saves a lot space. DSPPA multichannel digital power amplifier includes 2 series. DA***5 is the 2 channel digital power amplifier series, covering 2x**5W, 2x**0W, 2x**0W, while DA***0 is the 4 channel power amplifier series, covering 4x*0W, 4x**5W, 4x**0W. DSPPA digital mixer power amplifier includes following series: Mini*0—2x*0W Digital Mixer Amplifier with USB/SD/AUX/Bluetooth, MP*5—*5W Mini Digital Mixer Amplifier, MP*5U Series*-Mini Digital Mixer Amplifier with USB & Bluetooth, covering *5W, *0W and **0W, MP***6 Series*-Mini Digital Mixer Amplifier with USB & Bluetooth, covering *0W, **0W.
