Evertz - 520AD4-HD - HD/SD-SDI Audio De-embedder with 4 非平衡 AES Outputs

520AD4-HD

HD/SD-SDI Audio De-embedder with 4 非平衡 AES Outputs

The 520AD4-HD Audio De-embedder extracts embedded audio from 2 specified groups as defined by SMPTE 299M from a 1.5Gb/s serial HDTV or as defined by SMPTE 272M from a 270Mb/s serial SD video signal.

Up to 8 selected channels may be delayed up to 3 seconds and re-embedded onto the output video and/or directed to 4 AES outputs. An extra AES input is provided as a backup channel, in case of loss of primary, or as the source of voice-over. The video output may be optionally delayed up to 5 frames to achieve lip sync with the audio.

This device also handles the Dolby® E Metadata in VANC. The module has multiple sources for this metadata including VANC, and externally supplied metadata. The decoded or de-embedded Dolby® E metadata can be provided as an output for downstream devices (ie. Dolby® E encoders etc.).

VistaLINK® enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems such as Evertz VistaLINK® PRO locally or remotely.

520AD4-HD 安装在一个 3RU 的 500FR exponent 主机，能装最多 16 个模块。

特点

Supports SMPTE 292M (1.5Gb/s) or SMPTE 259M (270Mb/s) serial digital video signals
Video input relay bypass for power failure bypass protection.
AES input for backup/voice-over source
2 processed video outputs
4 AES de-embedded and processed outputs
1 Dolby Metadata output (RS-422/485)
De-embeds and re-embeds 2 audio groups - user-selectable
Selectable audio sources for AES and embedded outputs
Adjustable video (up to 7 frames) and audio delay (up to 3 seconds) to achieve lip sync at output

- Headphone jack with monitoring stereo down-mix
- Card edge LEDs for module status, Video and Audio present
- Card edge display for card status & audio channel peak levels bar graphs
- Configurable Dolby® Metadata input and output
- 当此模块与 500FC VistaLINK® 主机控制器一起装在同一台 500FR 主机上时，允许VistaLINK® 通过SNMP (使用VistaLINK® PRO) 进行远程监测与控制。
