Pre amplifier and DAC
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.
The name Director describes its function pretty well. It is the heard of the stereo system to which all components are being connected: sources, amplifier, active speakers, headphone amps, phono preamplifier etc. It determines what, with what and how loud we hear.
Director is a full-fledged stereo preamplifier with an extraordinary DA converter. There is provision for connecting up to six stereo sources two in the analog domain offering RCA connectors for e.g. phono preamplifier like the Phonos and four in the digital domain with USB, AES, Coaxial and Optical connectors.
At the output side a power amplifier or active loudspeakers can be connected balanced (XLR) and unbalanced (RCA). We recommend the Performer s800 as power amplifier in order to maintain a 120V Rail audio chain from the DAC to the speakers for best audio performance.
