Product Description

The SoundPals™ ASDM-4 Audio de-embedder offers an economic yet versatile means of ingesting the various digital TV standards and de-embedding the four AES pairs (8 channels) of audio.

The unit auto-senses the video format (HD or SD SDI) that is applied to the looping input.

All four AES3 (2 channels each) are available on Phoenix connectors at the rear of the unit. Four AES3id (BNC) outputs are also available at the same time. Provision is made for two-channel headphone monitoring along with embedded group and channel selection.

Like all of the SoundPals line, the ASDM-4 de-embedders are housed in a compact, rugged aluminum enclosure. The Power supply is not included.
