[. . . ] 8925EMB-U SD/HD Unbalanced Audio Embedder Key Features · Eight-channel (four stream) SD/HD digital audio embedder (multiplexer) · Four unbalanced AES inputs · Accepts asynchronous PCM audio · Supports Dolby E · Three SD/HD SDI outputs with embedded audio · Sample rate conversion accepts 32 kHz, 44. 1 kHz, 48 kHz, or 96 kHz · Embeds 20 or 24 bits · Fiber-ready option for receiving or transmitting over fiber 21 The 8925EMB-U is a compact eight-channel SD/HD digital audio embedder (multiplexer) module. [. . . ] The AES inputs can handle asynchronous audio and sampling rates from 32 kHz to 96 kHz, which are converted to synchronous 48 kHz embedded within the video stream. With its fiber-ready architecture, the 8925EMB-U can be configured to support up to two fiber inputs and two fiber outputs. With the fiber transmitter or transceiver option, it can take video from copper or fiber, embed audio, and transmit over fiber in one single slot. The receiver option makes it ideal for receiving incoming feeds from longer distances and locally embedding audio.
