These versatile modules embed or de-embed audio into or from a wide range of SDI video signal formats up to 12G. 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 - 3G, Unbalanced AES audio
abgekündigt
This supports unbalanced AES3id audio inputs and outputs using four BNC connectors, AES 1 to 4. AES 1+2 and AES 3+4 are independent channels, so the device may be used either to embed or de-embed four audio channels or alternatively it can function as a dual embedder/de-embedder. Additional audio groups may be embedded or de-embedded by cascading two modules together. Each channel is configured using DIP and rotary switches. Audio groups may be selected using rotary switches. An SDTV 24-bit mode may be selected. The PDM 1284 B automatically detects the audio format and de-selects the sample-rate converters to preserve encoded bit streams such as DolbyE; sample-rate converters can be permanently switched off. Audio connectivity is by way of 4x AES3id unbalanced inputs or outputs, 75ohms, BNC.
Included accessories: AC power supply. Note: SFP module not included.

PDM 1284-D - 3G, 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 connectivity is by way of 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.

PDM 1383 - 3G, Analogue Audio
This supports four balanced analogue audio inputs and four outputs using a 25-pin D-Sub connector. Four audio channels are de-embedded and embedded simultaneously from and to SDI video formats up to 3Gbit (1080p60); the module will de-embed and output the audio from the selected audio group before overwriting. Additional audio groups may be embedded or de-embedded by cascading two modules together. Up to four modules can be cascaded to provide up to 16 analogue audio channels over a single fibre link. The audio group is selected using a rotary switch. A second rotary switch sets either the analogue full scale level to 12/15/18/20/22/24dBu or the audio to 'line level'. An SDTV 24-bit mode may be selected.
| Analogue audio connectivity by way of 4x balanced analogue audio inputs, 10k ohms, 25-pin D-Sub; 4x analogue audio outputs, less than 100 ohms, 25-pin D-Sub. A D-Sub to screw-terminal adapter PCB is included. |

PDM 1484-D - 12G, AES/Analog Audio
PDM 1484 D is an AES audio embedder and de-embedder designed for a wide range of SDI video formats up to 12G. It supports balanced AES/analogue audio I/O using a 25-pin SubD type connector. Audio groups are selected using the rotary switches, and its possible to embed and de-embed additional audio groups by cascading modules together. Simultaneous embedding and de-embedding means the module will de-embed and output the audio from the selected audio group before overwriting with new audio (if required). The module automatically detects audio formats and will deactivate the sample rate converters to preserve encoded bit streams such as DolbyE. The “auto black” mode uses a black video frame if no SDI input is present. This allows the module to embed audio even when no video source is available. This mode is useful if the module is being used in an “audio only” application. The module is also compatible with the yelloGUI software package, which provides access to a host of additional internal settings which includes manual insertion of metadata (AFD,WSS,VI). A 1kHz test tone generator is included for audio testing purposes. An SDI fibre input and output is also provided with a variety of plug in SFP options available.
Included accessories: AC power supply, RBO A025. Note: SFP module not included.
