15 : 1.DPC Programming System
The DPC technology represents the most effective tool available for the acoustic designer to achieve unprecedented results
in terms of control over the transducer displacement and system performance in low frequencies. Thanks to the differential
pressure control, the behavior of subwoofer and low frequency applications can be modeled in order to modify the systems
response, increase sound pressure level capabilities and enhance the overall efficiency.
A DPC system is composed by:
f
f
Class-D amp module;
f
f
differential pressure sensor;
f
f
Zero-latency DSP board;
f
f
low impedance transducer
The DPC system performs a real time feedback between the actual acoustic emission of the loudspeaker and the
instantaneous displacement of the transducer. By knowing the pressure field generated by the loudspeaker, the Zero Latency
DSP controls the transducer displacement and adaptively modify the system emission. The system is capable to overcomes
transducers non linearities, offering a complete control over sonic performance. In addition, DSP provides the needed
algorithms for a complete loudspeaker tuning.
Using ProManager Plus™ is possible creating a custom model based on Zero Latency DSP (included on M-Drive) or based
on an additional Powersoft DSP-4. Once you have created and exported the custom Armonía Plugin, the loudspeaker equipped
with M-Drive can be recognized and managed via ArmoníaPlus™ software.
