Product Description

The SoundPals™ ASDM-8 HD Audio de-embedder offers the user an economic yet versatile means of ingesting the various digital video standards and de-embedding up to eight channels of analog audio at line level.

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

All eight line-level outputs are available on Phoenix connectors at the rear of the unit. Provision is made for two-channel headphone monitoring along with embedded group and channel selection. Like all of the SoundPals™ line, the ASDM-8 is housed in a compact, rugged aluminum enclosure. The Power supply is not included.
