3 Overview
The Kramer
VA-256P
is a professional digital audio delay that can be used as
an AES-ID3 (75 ) to AES/EBU (110 ) converter, as a digital audio
switcher, and as an audio delay line.
The high-performance
VA-256P
:
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 4096 msec
3
in increments of
1msec
Is EIAJ CP1201, IEC-60958, AES3, AES-ID3 and AES/EBU 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
To achieve the best performance:
Connect 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)
Avoid interference from neighboring electrical appliances and position your

away from moisture, excessive sunlight and dust
In applications with high interference, shielded cable will give better results.
