AMX-8952
4K UHD 12G-SDI Embedder / De-embedder and Frame Synchronizer
AMX-8952 is a key building block, providing audio embedding, de-embedding and synchronization in HD-SDI and UHD 12G-SDI environments. This enables your infrastructure to support the next generation of high-quality production with technology that is scalable, easily deployed, and reliable.
The AMX-8952 family consists of three variants that support unbalanced AES, balanced AES or analog audio interfaces. The audio interfaces are bi-directional, so one card is configurable as embedder or de-embedder, making it easy to deploy wherever you need it.
The card features useful audio processing such as audio shuffling and per-channel gain and delay, which enables you to make critical adjustments to incoming feeds. An optional Frame Synchronizer provides synchronization and adjustable video delay.
AMX also offers a secondary 12G-SDI input, allowing for clean/quiet switching triggered manually or by loss-of-signal detection. This is a great solution for signal path protection switching.
Full control and monitoring of the card are available via the DashBoard control system, which makes it easy to integrate AMX-8952 into your facility’s centralized control scheme.

Embed in UHD A key building block in any SDI facility, AMX allows you to embed and de-embed audio into HD and UHD SDI workflows. We make it easy to marry your audio workflow with your video production. |
Synchronize in UHD Take advantage of the remote feeds offered by AMX. The optional Frame Synchronizer with video delay makes AMX a great edge device for your mobile or studio installation. |
Clean Switch in UHD With primary and backup inputs, AMX provides clean/quiet switching wherever you need it. Additionally, ensure your critical paths are protected with loss-of signal failover. |
