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 .
Included accessories: All Yellobrik modules are supplied with a plug-top power supply with UK, US, Australian and European plug fittings and wall-mounting brackets.
Optional accessories: OH-TR-1 or OH-TR-3-1550 fibre transceiver module, see below. Power adapter cables for 12V working, alternative power supplies and a rack-mounting frame for up to 14 Yellobrik modules are available. Please see Lynx Yellobrik power supplies and mounting accessories. Power adapter cables for 12V working, alternative power supplies and a rack-mounting frame for up to 14 Yellobrik modules are available. Please see Lynx Yellobrik power supplies and mounting accessories.
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.
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.
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.
These plug into the 'cage' on the side of the module and can be added at any time, to provide an SDI output over fibre.
Note (1): Maximum at 3Gbit/s.
These plug into the 'cage' on the side of the module and can be added at any time. The 'transceivers' can receive one SDI signal from one fibre and transmit an SDI signal over a second fibre simultaneously.
These bi-directional SFP modules send and receive SDI signals over a single fibre and may be used with the PDM 1383 module. They must be used as a pair fitted at either end of the fibre.
These plug into the 'cage' on the side of the module and can be added at any time to enable the module to receive a fibre optic input signal.
