Superior Analog Circuitry - XMAX Class A Preamplifiers
The DigiMax FS starts with eight custom-designed high-voltage, discrete, XMAX Class A microphone preamplifiers. PreSonus knows that the preamplifier is a key component in the sonic quality of a recording. The job of a microphone preamplifier is to boost microphone level signals to line level so that the signal can be converted from analog to digital. This mic to line boost is generally a preamplification of over 400 times the voltage of the original mic level signal. This preamplification stage is one of the most important stages that the signal will go through before converted to digital, and is why a high performance preamplifier is important to achieving great results. A cheap "off the shelf op-amp" type mic preamp that is found in many 8 channel preamps with digital output, translates into thin, noisy and harsh results.

New Advanced Platform Technology - JetPLL
The synchronization of the DigiMax FS is handled by patented JetPLLTM jitter reduction technology. JetPLLTM incorporates noise shaping to virtually remove all audio band jitter. JetPLLTM ensures the highest converter performance possible, resulting in better stereo separation and clearer more transparent audio. JetPLLTM delivers ultra-fast locking to any digital format, through a wide range of frequencies and is extremely robust, and tolerant of wide variations in clock frequencies. JetPLLTM ensures near perfect clock performance when networking audio devices thus creating the most stable and robust synchronization to all devices.
