Product Details

This product is no longer available. If you have an IP7‑SE8 and require support for half‑duplex audio using the speaker as both a speaker and microphone (talkback or single‑transducer mode), you should look to the IP7‑FX – IP Intercom and Paging Amplifier.

The IP7‑MSR‑BRD (Mic/Speaker Relay Board) for the IP7‑SE8 allows an 8‑ohm speaker to be used as both a microphone and speaker. The board incorporates a relay to automatically switch the speaker between the IP7‑SE8’s microphone and speaker inputs. A suitable 8‑ohm, re‑entrant‑capable speaker or horn is required to ensure proper gain.
