#### Video Delay

- User selectable 0 ... 15 frames, can be disabled

#### Audio

- 24-bit, transparent forwarding of PCM and compressed audio
- Sample rate = 48kHz (SDI compliant)
- Channels = 16 inputs and 16 outputs (4 groups of 4 channels each)
- Delay = Embedder audio delay selectable 0 ... 320ms per channel

#### Metadata (RDD6)

- 1 channel input, 1 channel output, SDID selectable

#### BNC Input

- Impedance = 75Ohm
- Return loss = >15dB 5 ... 1485MHz; >10dB 1485 ... 2970MHz
- Maximum cable length = 250m (SD), 230m (HD), 140m (3G) using Belden 1694A cable
- Jitter tolerance = >0.7UI (alignment)

#### BNC Output

- Impedance = 75Ohm
- Output voltage = 0.8Vpp (typical)
- Return loss = >15dB 5 ... 1485MHz; >10dB 1485 - 2970MHz
- Output jitter = <0.2UI (alignment), <0.5UI (timing)

#### Latency

- Video latency input to output = 120 ... 200 pixel, depending on video standard
- Audio latency input to output, embedder and de-embedder combined = <0.6ms (HD, 3G), <2ms (SD)

#### General Features

- Power fail relay bypass (may be enabled/disabled via GUI)
- Lip-sync compensation for processed and non-processed audio signals
- Dedicated routing for non-processed channels; all channels (maximum 16) can be routed to/from the device or looped through
- Test pattern generator (no genlock)
- Master-sync capable
- ITU-R BT.1685 / ARIB STD-B39 metadata support
