3 Overview
The Kramer
VA-680D
is a digital delay line that can be used as a
coax-to-optical or optical-to-coax converter, as a coax or optical repeater, as a
digital audio switcher and as an audio delay line.
The high-performance
VA-680D
:
Lets you adjust for lip sync errors so that the audio delay will match the
video delay
1
Lets you adjust the brightness of the display via the dimmer setting
Automatically sets the maximum delay time according to the input
sample rate (for each input channel)
Recalls the previously set display brightness level and input settings
2
via
its non-volatile memory after powering up
Provides a delay time, ranging from 0 up to 999 milliseconds
3
in increments of
1msec
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-680D
away from moisture, excessive sunlight and dust
