The Director combines two units in one: a reference-class preamplifier with six inputs (2x analog and 4x digital) and both balanced and unbalanced outputs as well as a reference-class DA converter for PCM up to 384 kHz and up to Double Rate DSD (DSD128).

The technical basis of all Professional Fidelity units is our proprietory 120 V Rail Technology, which we also call VOLTAiR technology. The name makes reference to the unequalled high voltage of 120 V (+/-60 V DC) and the huge dynamic range of over 140 dB that goes with it.
