8-channel 3G/HD/SD AES Audio + Metadata Embedder
Model: AMX-3981
- Video:
- 3G/HD/SD input
- Supports 3Gbps level A (mapping 1) and level B
- Audio/video de-glitcher to handle video hot switch at the input
- Automatic detection of input video loss and switchover to local grey for continuity of embedded audio

The AMX-3981 is an advanced high quality audio processor which embeds up to eight (8) AES signals into a 3G/HD/SD video signal. Each AES input can accept different sample rates, or even asynchronous audio, and will be resampled at 48 kHz by a sample rate converter, which can be manually or automatically disabled in the presence of non-PCM audio.
Metadata:
AFD (SMPTE-2016), VLI (RP-186) and WSS insertion
Linear timecode (LTC) embedding into DVITC (SD) or ATC (3G/HD)
Audio metadata insertion and extraction (SMPTE 2020-A)
RS-422 serial data input and output to carry audio metadata
3 GPI I/O that can be inserted or extracted in the TC user bits, they can also be used for automation, user preset recall and loudness reset
Audio:
8 AES outputs
Sample rate conversion for asynchronous AES inputs
Full audio shuffling and mixing on a channel basis
32 channels internal audio processing
Automation capabilities based on audio signal type detection
Audio 5.1 surround downmix to Lt/Rt or Lo/Ro
Audio dynamic processor option (compressor/limiter/expander)
Audio delay adjustments of up to ±2 seconds to compensate for lip sync issues
The AMX-3981 can simultaneously process up to 32 channels of audio (16 channels from the discrete AES inputs, and 16 channels of embedded audio). Functions include downmixing, proc amp, channel shuffling and mixing. Options include automatic loudness control, dynamic processing (limiter, compressor and expander) and loudness measurement. The AMX-3981 generates audio/video fingerprints (via an iControl option) to detect and measure lip sync errors in a broadcast facility.
