This auction is for a Gentner Digital Hybrid broadcast phone-in interface - which connects a telephone line to your broadcast console. A computer-controlled line optimization process (the burst of white noise you hear when the DJ answers the call) ensures that the system is adjusted for the specific line conditions associated with each incoming call.

The large majority of phone-in calls you hear on the air today are passing through one of this range of boxes. The device may also be used to provide an IFB feed to remote talent over a phone line.

Cosmetic and functional condition is excellent - the photos are of the actual item for sale. The unit has been tested by connecting an audio source to the send input and an amp/speaker to the mix output. The unit passes audio in both directions in broadcast quality.

This is model number 910-012-001. Input voltage can range from 100-240V.

For your peace of mind, I will offer bidders in the USA a guarantee that this item will arrive in the working condition described in the listing - provided that you notify me of any issues within 48 hours of receipt. For bidders elsew this will be sold as-is unless agreed otherwise in writing.

Manufacturer's Product Overview

Are you looking for the very best, most affordable dual digital telephone hybrid available? You just found it. The DH22 Dual Digital Hybrid incorporates the latest in DSP digital technology to provide you with the best sound and easiest installation.

The DH22 is a high quality dual line telephone interface that interconnects two standard telephone lines and your audio equipment, allowing you the ability to send audio to and receive audio from the connected telephone lines. The DH22 is ideal when the very best audio quality and conferencing capabilities are required in talk shows, news feeds, production, recording studios, and Internet applications.

Our newest DSP technology delivers better and more reliable sound quality. The DH22 delivers the deepest and most stable hybrid null, ensuring maximum isolation between the send and caller audio. That means no echo and no “bottom of the barrel” sound.

In addition, we’ve added selectable automatic gain control (AGC) and caller ducking. With AGC, each call will be delivered to your equipment at the same level. Caller ducking reduces the caller’s audio level when the announcer speaks, providing a more “controlled” environment. We’ve also added a speaker amplifier so you can connect a speaker directly to the unit and monitor callers without headphones.

Installing hybrids used to be a hassle. If your console didn’t have a mix-minus bus, it was difficult to create one. The DH22 solves this problem with the internal mix-minus. Simply take the mix output of you console and feed it to the DH22.
