THE DH20 Digital Hybrid incorporates the latest in DSP technology to provide the best sound and easiest installation.
Available from Richardson Electronics , the DH20 is a high quality, single line telephone interface that interconnects a standard telephone line and audio equipment, allowing the ability to send audio to and receive audio from a connected telephone line.
The DH20 is ideal when the very best audio quality is required for talk shows, news feeds, production, recording studios and Internet applications.
This newest DSP technology delivers better and more reliable sound quality.
The DH20 offers 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, selectable automatic gain control (AGC) and caller ducking has been added. With AGC, each call will be delivered to the equipment at the same level. Caller ducking reduces the caller's audio level when the announcer speaks, providing a more "controlled" environment.
A speaker amplifier has also been added so customers can connect a speaker directly to the unit and monitor callers without headphones.
