Overview

SP 393 Anti-Feedback

Even the best designed paging systems can experience feedback. Now you can eliminate annoying feedback over your paging speakers with Viking’s model SP393 digital antifeedback paging interface.
The SP393 utilizes state of the art digital recording technology to record the “live� page from a phone system’s paging port output or unused trunk port. The SP393 then immediately plays back the recorded page once or twice (selectable) over the paging system.
Pages of up to 60 seconds can be stored and the SP393 automatically adjusts to the page length for faster processing. In addition, the SP393 can be programmed to provide pre-page and post-page alert tones.
