Lynx Technik yellobrik PDM 1284 D AES audio Embedder / De-embedder (balanced AES)

The Yellobrik PDM 1284 D is a versatile AES audio embedder and de-embedder designed to support a wide range of SDI video formats up to 3Gbit/s. It facilitates the embedding and de-embedding of balanced AES3 audio via a 25-pin Sub-D connector, making it suitable for various broadcast applications.

Key Features

• Simultaneous embedding and de-embedding of audio signals
• Supports 3G-SDI Level A and Level B formats
• Compatible with SDI video formats up to 3Gbit/s (1080p60)
• Four AES inputs/outputs with selectable audio groups
• Optional fiber I/O for extended connectivity
• Integrated 1 kHz test tone generator for audio testing
• Automatic detection of PCM and encoded audio formats
• 'Auto black' mode enables audio embedding even without a video source
• Selectable SDTV 24-bit mode
• LED indicators for video and audio presence
• Compatible with yelloGUI for accessing additional internal settings
