Solving Feedback Problems

Valcom Support Services recommend the use of a V-9964 Stacking Feedback Eliminator for use with feedback problems.

Feedback is caused when the page which is being broadcasted feeds back to the handset making the page. This creates a terrible squealing through the speakers. As a rule of thumb, if you can see one of the speakers you are paging you have a good chance of producing feedback.

The V-9964 is a very clever device which has been developed and updated over the past ten years to combat feedback.

We have installed the V-9964 to numerous customers and sectors including:

  • Heavy Manufacturing
  • Offices
  • Academies
  • Colleges
  • Hospitals
  • Emergency services

What the V-9964 actually does, is to record the page being made live. Once the person making the page replaces their handset after completing the page, the V-9964 replays the page over the speaker system.

You have the option (via option switches) of having the page played twice. This is a very useful feature as the first time the page is played it gathers the attention of personnel. It acts like a pre-alert tone so that the second time the page is played people are aware of a page being made.

 V-9964 Features:

  • Multiple messages can be recorded simultaneously and stacked in order, then played over the speaker system in the order the pages were recorded
  • Four V-9964’s can be interconnected to allow eight simultaneous pages
  • The V-9964 stacks the messages whilst a page is being made
  • Solid State Design
  • LED indicators showing the status of a page being recorded or played
  • Pre Alert Announcement tone
  • Background music input
  • The choice of 8 or 600 ohms loop
  • Screw terminal connections for ease of installation

Emergency messages can override pages being played
