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.

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.
