Want to know more about this product? 



The JUSTIN 808 maintains time alignment between analog FM and HD1 channels to within 23 microseconds (±1 sample).

The JUSTIN 808 only makes its time-alignment adjustments to the HD1 channel leaving the critical FM transmission untouched – an important distinction when choosing a time-alignment processor.

No more lost words, stuttering, echoes, or level shifts. The entire sync process is 100% automatic, and the JUSTIN’s Web interface features SNMP support and dispatches e-mail and SMS alarm messages.

Approved by DTS/iBiquity for HD Radio™.
