MSX IPal Block Diagram
The closed loop system is a patented technology dubbed DPC® (Differential Pressure Control) that is the core of the IPAL system.
Without an accurate method of linking acoustic output back to the electrical domain the system would be impossible. The
pressure sensor was developed to provide this vital link in the chain.
IPAL used “zero"latency DSP to control the signal applied to the amplifier with input from the DPC system. Low latency is vital
since corrections to the output signal have to be made in real time not several milliseconds after an event. The DSP in the IPAL
system was developed with an innovative architecture that achieves an astonishing 10µs making it fast enough to easily handle
any sudden transient deviations in the sub band.
