The advent of ever more powerful video processing built into successive generations of display devices and the proliferation of DVD, has inspired a rush of interest in high quality audio and video for the home. But the delivery of great pictures and sound has itself created new challenges. The technology used to produce large, artefact-free images also introduces a delay between pictures and sound. This is particularly noticeable in speech, where the voice comes first and the lips move after. Lip-syncing anomalies may also affect satellite broadcasts and can occur when the transfer of older movie soundtracks to digital surround sound for DVD is not as precise as it could be. The effect can be so pronounced that the film or broadcast becomes difficult to watch and the experience profoundly disfigured.
Certain A/V processors have corrective circuitry in-built, but Primare has determined that these processors work best with a signal that is already synced; hence the introduction of Primare’s ‘Delay Box’. Placed between source and processor, this advanced digital lip-syncing device delays the system sound by tiny increments and relieves the processor of the power and memory drain associated with integral delay correction. It’s also an innovative upgrade for those systems lacking this facility.
The Delay Box from Primare will restore perfect lip-syncing to the audio output from your digital satellite receiver and DVD-player. The satellite receiver connects optically and DVD-player coaxially to the Delay Box. From the Delay Box, which seamlessly performs format conversion, a single coax (or toslink) feeds the audio processor.
Primare’s Delay Box has four presets, two per input (coax and optical) and adjustable delay over a 0 - 600 ms range. There is also a true bypass of all delay correction circuits.
With the introduction of Primare’s Delay Box, the destructive effect of poor lip-syncing, inherent in high-quality display devices and present on certain DVDs is consigned to the past with an easy to use, revelatory upgrade.
