The 7730DAC line of serial digital video to component analog converters are broadcast quality D to A's with an extensive list of additional features. High quality digital to analog conversion of audio can be packaged with the video to create a D to A frame synchronizer with audio demux. In addition, Evertz fault monitoring processing will analyze and report video and audio problems via an On-Screen-Display, or remotely via VistaLINK® SNMP.

Menu adjustable free running frequency
VU/PPM bargraph level Indicators
Decodes vertical interval time code (VITC), and "burns" the time code into the monitoring output picture
A comprehensive on screen display is available to configure the various features of the module
Flexible configuration of the text and audio bar graph information displays
An extensive list of error conditions can be monitored and fault conditions can be configured from these conditions
On screen messages can be triggered by the configured fault conditions
VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
One group (4 channels) of synchronous 20-bit audio is de-multiplexed from the incoming digital video
2 unbalanced AES audio inputs (up to 48kHz, 24 bits) on BNC
User selects EITHER the de-embedded audio or the input AES audio
The selected audio is delayed equivalently to the video delay with the +S option
4 high quality 24 bit audio channels are output (analog) as balanced on 2 removable barrier strips
Low impedance outputs (66 Ohms)
Analog audio output levels are adjustable
Additional audio delay of up to 5 seconds
Additional audio advance of up to 1 frame, depending on video delay Loss of video modes: pass audio, mute audio
