Mackenzie Labs OPM-1S
Single Channel Digital Page Stacker and Feedback Eliminator

OUR PART #  OPM-1S


The increased sophistication of today's intercom and paging systems requires products that are easily integrated into a wide variety of applications. They must also provide increased intelligibility with better system clarity, vocal definition and reliability.

Mackenzie Laboratories continues to respond to these requirements with the OPM-1S. Designed for use in high traffic public address systems, the OPM-1S, page stacker and feedback eliminator offers 4 minutes of audio storage with excellent audio clarity. Page stacking and record while play are key features of the OPM-1S design. The unit is able to stack and play up to 16 pages while recording new pages at the same time.

Additionally, the OPM-1S makes feedback through the paging system virtually impossible by opening the loop between the input microphone and speakers. This eliminates the potential for acoustic feedback while giving the user flexibility in the manner which pages are broadcast. Multiple operational modes, Dry or Loop Start, Page Repeat, Delay, Pre-Page Tone and Priority bypass features allow the OPM-1S to be tailored to many paging applications.
