DEVENS, MA, Jan. 30th 2018 — Comrex, a leader in VoIP and video-over-IP technology, will debut a new product, EarShot IFB, at NAB 2018. EarShot IFB is designed to help TV stations reduce costs and provide more flexibility for remote IFB feeds.

“It needed to happen,” said Chris Crump, Comrex Sales Director. “We’d visit TV stations and see banks of old telephone auto-couplers connected to expensive analog phone lines. Most other phone tech has transitioned to Voice-over-IP (VoIP), but remote IFB audio remains stuck in the last century.”

EarShot IFB provides telephone-based live studio program and IFB audio to field-based remote broadcasts. Up to 30 users can listen to program or IFB feeds by calling into EarShot IFB with a mobile phone. EarShot IFB can handle up to 4 program feeds, or 2 IFB feeds. For higher fidelity, smartphone apps can be used to pull the audio in studio quality. EarShot IFB can be connected to low-cost cloud-based VoIP service, or tied to a station’s VoIP PBX.

“With our years of experience in putting VoIP calls on air,” said Tom Hartnett, Comrex Technical Director, “it was a no-brainer to provide a simple hardware solution to the IFB problem. The folks we talked to were sick of paying for a dozen or more POTS lines to provide this function. EarShot IFB will pay for itself within a couple of months in phone service savings alone.”

Comrex will be debuting EarShot IFB at NAB 2018 at Booth C2330. EarShot IFB will be available for purchase in mid-2018. For more information, contact
