Class-AB Amplifer with DSP Process
Class-AB Amplifer with DSP Process
1. MPA Amplifier: High Performance, Lightweight amplifier2. Integrated High Performance DSP Technology for better features and control3. Complete Digital Filtering and RMS Compression/Limiting provide maximum output while protecting speakers4. USB/RS485 or USB/Tcp/Ip remote control interfaces for the max flexibility in remotely controlling and networking the unit5. Standby Function for shutting down the Power Stage maintaining “alive” the digital control section6. Efficient forced-air fans prevent excessive thermal buildup7. Electronically balanced XLR inputs and Speakon® outputs
Class-AB Amplifier with Powerful and Sophisticated DSP Sound Processing
1. Very powerful DSP processes for the Sound filtering and the Dynamic control are implemented within anyone of the MPA Series amplifiers.2. Each process can be edited through the front panels available controls or via USB/RS485 and TCP/IP interfaces (T Model).Particularly, the available DSP processes are the following: Input Gain Control, 8 bands parametric Equalizer (Peaker filters +-15dBu gain OR Ist/2nd order High/Low Pass Shelving +-15dBu gain), from 6dB/Oct up to 24dB/Oct Hp/Lp filters for the XOver Section (Butterworth, Linkwitz/Riley or Bessel), Delay up to 850ms per channel. RMS Compressor/Limiter with Ratio.
3. Remote Control Pc Sw for MPA amplifier
An easy to use and Remote Control Sw is allowing to control the all MPA Amplifiers when used as single units or when networked.Through the Pc Sw Remote Control, more units can be edited and controlled all together when in network; the units can be anyone of the ones belonging to the MPA Series.Together with the all parameters related to the “pure” sound processing, many other functions are available by the Pc Sw Remote Control, such as Password management, complete Input/Output Gain Control, Temperature control, Protection andcomplete metering Set.The complete monitoring of the processes is done by Led meters on the MPA also on the front panel, so as on Pc Sw interface.
Class-AB MPA series Amplifire's Reliability protection function
a. CLIP/Limit :this function is used for preventing dangerous clip signal damage the speakers, CLIP/Limit monitors the distortion produced by amplifier output, when distortion exceeds 0.5%, CLIP/Limit will reduce the input signal to ensuresignal not distortion (CLIP).
b. Over-heat protection: If the amplifier works at full loading for a long time, the fans have reached the highest speed. If this status continue andthe temperature rise up to over 105 degree, the amplifier will go into over-heat protection status.
