Broadcast Audio Delay
A natural choice to any studio’s audio require-
ments, the AU51 is a 20-bit, broadcast quality
stereo Audio Delay with an adjustable range of up
to10.0 seconds. The delay can be adjusted in 0.01,
0.1, and1.0 second increments to accurately correct Lip Sync problems. It is very easy and simple to use. You just look at
the video while listening to the audio and turn the delay adjust knobs until the video and audio are correctly in sync. In
applications where the audio delay is a known fixed value, the delay can be preset at the factory.
The AU51D accepts either analog or digital audio signals and simultaneously output the delay audio in both analog and
digital forms. (In essence, it is also a digital to analog audio converter or vice versa). Accepting sampling frequency of
33.1KHz, 44.1KHz, or 48KHz gives AU51D the flexibility to deal with the increasing varieties of digital audio formats exist
today. The AU51D-EM steps up with ability to extract the audio signals from the embedded SDI signal.
◆ From 1 frame to 16 frames delay
◆ Adjustable resolution: one field or
one frame
◆ Composite input and output
◆ Desktop, 1/2 rack or 1RU version
DE41 Variable Video Delay
The DE41series is a great-valued video frame
or field delay. It provides full bandwidth
output signals to your VCRs, vamera or
satellite feed. They utilize front mounted
controls to adjust video delay. They are useful in matching video sources with varied cable runs, and will take the place of
the mound of coiled coax that some studios use to time equipment.

channel
◆ Accept SMPTE 259M SDI signal
◆ Digital audio extractor from embedded SDI
input signal
◆ Automatic audio format conversion and
simultaneously outputs in analog or digital
format
