Our newest DSP technology delivers better and more reliable sound quality. The DH20 delivers the deepest and most stable hybrid null, ensuring maximum isolation between the send and caller audio. That mean 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.

Details

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 very good - the photos are of the actual item for sale.  The face plate is in very good condition with the silk-screened legends nice and clean. 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.
