Broadcast

Every digital processor (hardware or software) is implemented as software inside a form of a computer. However, because Breakaway Broadcast Processor is distributed as software, it is dependent on the performance of hardware it is installed in, and requires manual calibration using an oscilloscope to achieve stated performance. Proper installation is imperative, as with any audio processor.
