The SPL 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 the proprietary 120 V Rail Technology, which SPL 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. More information on the 120V Rail Technology can be found here. 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.
