The PDM 5248 is a versatile 16-Channel (8x AES) audio embedder/de-embedder, which can be used to address a variety of audio issues in broadcast. The module offers multiformat support for 12G-SDI formats up to 4K with 4:2:2 and 4:4:4 chroma sub-sampling at 10 or 12-bit depth.
The module can be switched between a 16 channel embedder or 16 channel de-embedder, or a combination of both. Up to 64 channels of audio are de-embedded from the input SDI signal and passed into the audio processing stage. In embedder mode, 16 channels of external audio are passed into the audio processing stage. Audio processing includes adjustable gain, phase invert and mute for all 64 channels as well as a selectable mono mix-down function for each left and right pair.
The processed audio is passed onto a 80 x 80 output crossbar where the audio for the embedder and the external outputs can be user mapped.
The PDM 5248 card module allows for up to 30 frames of programmable output delay adjustable in frames, lines and pixels.
