3 Overview

The Kramer VA-256Dis a digital delay line that can be used as a coax-to-optical or optical-to-coax converter, as a coax or optical repeater, and as an audio delay line.

The high-performance VA-256D:

￿￿Lets you adjust for lip sync errors so that the audio delay will match the video delay1

￿￿Provides a user-programmable delay of the audio signal

￿￿Is EIAJ CP1201, IEC-60958, AES3, S/PDIF compatible and supports 32kHz to 96kHz sample frequency range

￿￿Is fully transparent to the digital stream, making it ideal for the most demanding audio applications including home cinema and professional audio applications (such as PCM, Dolby Digital, DTS, AES and so on)

￿￿Is 12VDC fed and is housed in a DigiTOOLS enclosure

Achieving the best performance means:

￿￿Connecting only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)

￿￿Avoiding interference that may adversely influence signal quality and positioning the VA-256Daway from moisture, excessive sunlight and dust
