A digital delay that works
For our new ES and VHD systems we needed to develop a digital based, driver alignment, audio delay system that would provide unprecedented resolution, accuracy and definition. The fact that nearly every other pro-audio manufacturer accepted the barriers and quality limitations of low sampling rate PCM systems should have taken us down this path of compromise, but it didn’t.

Instead we looked to the field of Hi-fi where people were trying to improve things, so why not in Pro Audio?

Sony and Philips realized that
even compact disc had severe
limitations because of its PCM
based system; with a 16 Bit,
44kHz sampling frequency only four samples were available at 10kHz. That lack of sampling meant that the machines had to fill in the gaps and make up the rest of the information in trying to recreate the original curve. This resulted in the harshness and lack of definition we hear in some digital recordings.

Together they went on to develop Direct Stream Digital (DSD™) which is capable of capturing a full range of naturally occurring sounds and decays with unparalleled audio resolution. The result was an enormous step forward in terms of audio quality and manifested itself as Super Audio CD on the open market.

VHD features DSD™ technology as part of the speaker alignment system’s delay circuit and increases sampling from the industry standard 96kHz to an incredible 6.0MHz with 60 times greater resolution.

This level of detail and resolution brings digital audio closer than ever before to the true analogue curve.
