LYNX YELLOBRIK AUDIO EMBEDDERS AND DE-EMBEDDERS

These versatile modules embed or de-embed audio into or from a wide range of SDI video signal formats up to 3Gbit/s. Part of the yellobrik range manufactured by Lynx Technik, they all offer such useful features as selectable audio groups, video-present and audio status LEDs, integrated test-tone generators, automatic black output if no video is present and fibre input/output capability by means of optional SFP fibre modules. The range includes designs for use with either unbalanced AES digital, balanced AES digital or balanced analogue audio. Modules may be used alone, or mounted in an optional rack-mounting frame.

The 'auto black' mode uses a black video frame if no SDI input is present, which allows the module to embed audio even when no video source is available. This mode is useful if the application is only transporting multi-channel audio between locations, either electrically or over fibre. A typical application would be bi-directional four-channel analogue comms over one or two fibres to a commentary or other remote position.

A 1kHz test-tone generator is integrated for audio testing purposes. The modules include an LED for video-present indication as well as multi-colour audio-status LEDs. The optional SFP fibre modules add fibre transceiver functionality for embedding and de-embedding directly from the fibre. When the fibre input is used, both fibre and electrical SDI outputs are provided. An 'Audio Shuffle' tool is included which provides a full mono crossbar, allowing audio channel shuffling between groups at both the embedder and audio output stages. This functionality can be retrospectively installed in existing units by installing the latest firmware available free from www.lynx-technik.com .

PDM 1284-B - Unbalanced AES audioabgekündigt

PDM 1284-D - Balanced AES Audio

This supports four balanced AES3 audio inputs and four outputs using a 25-pin D-Sub connector. Eight audio channels are de-embedded and embedded simultaneously from and to SDI video formats up to 3Gbit/s (1080p60); the module will de-embed and output the audio from the selected audio groups before overwriting. Additional audio groups may be embedded or de-embedded by cascading two modules together.

Two audio groups, one for AES1+2 and one for AES 3+4, are selected using rotary switches. An SDTV 24-bit mode may be selected. The PDM 1284 D automatically detects the audio format and deactivates the sample-rate converters to preserve encoded bit streams such as DolbyE; sample rate converters can be permanently switched off.

Audio inputs/outputs: 4x AES3 balanced input, 110 ohms, 25-pin D-Sub; 4x AES3 balanced outputs, 110 ohms, 25-pin D-Sub. A D-Sub to screw-terminal adapter PCB is included.
