SONIFEX REDBOX AUDIO EMBEDDERS AND DE-EMBEDDERS

Housed in the familiar Redbox chassis, 1U rack-mounting, with a universal power supply, these designs offer embedding and de-embedding for analogue and digital audio signals into and out of 3G, HD and SD-SDI video signals. They have simple controls, and offer remote operation on serial and ethernet ports using Sonifex SCi software. The range offers embedding only, de-embedding only and models with both embedding and de-embedding capability.

Common Features

All have a triple-rate SDI receiver with automatic input-rate detection and equalisation as well as two re-clocked and individually buffered SDI outputs. They support the full range of 3G, SD and HD standards from NTSC and PAL up to 1080p 60Hz.

Where analogue inputs and outputs are present, input and output full-scale gain settings can be set with jumpers inside the case. The analogue audio input and output connections are balanced, connected in parallel on both mutipin and floating BNC connectors. One type can be used per output, they may be connected unbalanced without loss of level.

The de-embedding and embedding channel routing is controlled via three sets of controls on the front panel, all consisting of illuminating push-buttons with an arc of LEDs. The first set varies according to model and is used to select embedding and de-embedding parameters. The second set, labelled 'SDI', has two switches, each with four LEDS marked 1 to 4, to select SDI 'Group' and 'Group channel' respectively. These are used in conjunction with the first set of switches to select which of the audio channels, 1 to 4, from which group, 1 to 4, in the SDI stream is routed to which connector on the rear. The third is marked 'Status' and has seven LEDs: Groups 1, 2, 3, 4, 'SDI Lock', 'SDI Out 1', 'SDI Out 2'. An LED indicates power.

The rear panel in each case has a female BNC connector for the SDI video input, two BNC connectors for two re-clocked SDI video outputs as well as 9-pin female D-sub and RJ45 connectors for RS232 serial and 10/100Mb/s ethernet remote control respectively. An IEC inlet with adjacent fuse provides the AC power connection.

RB-VHDMA8 - De-embedder - 8x analogue outputs

This can selectively de-embed up to eight channels within any two audio groups contained within the video stream, to any of the analogue outputs. After this, the video becomes two independent streams, where the audio groups can be selectively deleted or passed through and then re-clocked and sent to the SDI outputs.

In addition to the common features, this has a group of two buttons to select audio de-embedding parameters. The first has two LED indicators and selects 'Bank' from a choice of 'De-embed 1' or 'De-embed 2'. The second selects 'Bank Chan' from a choice of 1, 2, 3, 4. The rear has two groups of four BNC connectors which provide the unbalanced audio 'Channel outputs' for 'De-embed bank 1' and 'D-embed bank 2'. Two female 25-pin D-Sub connectors provide the balanced audio outputs for 'De-embed bank 1' and 'De-embed bank 2'.

RB-VHEMA8 - Embedder - 8x analogue inputs

This can selectively embed up to eight analogue audio channels onto either of the two output video streams which are re-clocked and sent to the SDI outputs. It also has the capability to allow audio groups to be deleted or passed through untouched on each of the two video streams.

In addition to the common features, this has a group of two buttons to select audio embedding parameters. The first has two LED indicators and selects 'Bank' from a choice of 'Embed 1' or 'Embed 2'. The second selects 'Bank Chan' from a choice of 1, 2, 3, 4. The rear has two groups of four BNC connectors which provide the 'Channel inputs' for 'Embed bank 1' and 'Embed bank 2'. Two female 25-pin D-Sub connectors provide the balanced inputs for 'Embed bank 1' and 'Embed bank 2'.

RB-VHCMA4 - Embedder and de-embedder - 4x analogue in, out

This selectively de-embeds up to four channels within any audio group contained within the video stream to any of the analogue outputs. After this, the video becomes two independent streams, where the audio groups can be selectively deleted or passed through. The unit then embeds any of the four analogue input channels to available groups within each of the two video streams, which are then re-clocked and sent to the SDI outputs.

In addition to the common features, this has a group of two buttons to select audio embedding and de-embedding parameters. The first has two LED indicators and selects 'Bank' from a choice of 'Embed ' or 'De-embed'. The second selects 'Bank Chan' from a choice of 1, 2, 3, 4. The rear has two groups of four BNC connectors which provide the 'Channel inputs' for 'Embed bank' and 'Channel outputs' 'De-embed bank'. Two female 25-pin D-Sub connectors provide the balanced outputs for 'De-embed bank' and balanced inputs for 'Embed bank'.

RB-VHCMD16 - Embedder and de-embedder - 16x digital in, out

This selectively de-embeds any channel within any audio group contained within the video stream to any of the digital outputs. After which, the video becomes two independent streams, where the audio groups can be selectively deleted or passed through. The unit then embeds any of the digital input channels to available groups within each of the two video streams, which are then re-clocked and sent to the SDI outputs.

Each digital input is normally sample-rate converted to 48kHz before embedding, so that it is synchronous to the video input. Sample-rate conversion can be bypassed on a per-bank basis allowing SMPTE-337M data to be embedded. All digital outputs are output at 48kHz, synchronous to the video input. The digital inputs and outputs can be selected as AES or S/PDIF via jumpers situated inside the unit. The AES/EBU and S/PDIF input and output connectors are connected in parallel, allowing one type to be used per input or output.

In addition to the common features, this has a group of three buttons to select audio embedding and de-embedding parameters. The first has four LED indicators and selects 'Bank' from a choice 1, 2, 3, 4. The second selects 'Bank Chan' from a choice of 1, 2, 3, 4. The third selects 'Function' from a choice of 'De-embed' or 'Embed '. The rear has four groups of four BNC connectors which provide the 'Embed' inputs' and 'De-embed' outputs for 'Bank 1' to 'Bank 4'. Two female 25-pin D-Sub connectors provide the balanced AES embed inputs and outputs for 'Bank 1+2' and 'Bank 3+4' respectively.

Digital audio inputs and outputs: 3Vp-p +/- 20% , 110 ohms, balanced; 1V p-p +/- 20%, 75 ohms unbalanced. Input sample rates: 32-192kHz, converted to 48kHz. Output sample rate: 48kHz. Dynamic range: 138dB. Distortion: Better than -137dB THD+N, 997Hz, ref 0dBFS.
