JK Audio - Universal Host
VoIP/PBX Digital Hybrid
The Digital Hybrid for a Busy Desktop.
Universal Host easily converts your IP or PBX telephone into a professional, affordable interview station. This desktop digital hybrid provides talk show quality caller audio from most telephone systems. Simply connect between your telephone handset and the base of your telephone. The digital hybrid connects audio signals to your IP or PBX type telephone system through the telephone handset cord. Universal Host provides connections for a microphone, headphones, mixer, sound card, and telephone handset. The stereo output jack on the back of the unit provides your voice on one channel and only the caller’s voice on the other channel. The balanced XLR output jack contains only the caller’s voice. The Handset and Online buttons select between talking on the handset, or sending and receiving through the audio connections. A second switch selects between monitoring the caller or listening to the USB codec over the headphones.

Digital Signal Processor
The digital hybrid connects audio signals to a standard analog telephone line without the transmit / receive crosstalk common to analog hybrids. The Digital Signal Processor (DSP) continuously monitors both the phone line and audio signals to deliver excellent separation. This proprietary, dual-convergence echo canceller algorithm can achieve excellent separation, typically exceeding 50 dB, without any setup and without sending a noise burst down the line.
Talk Show Quality Interviews
Connect a professional dynamic mic and headphones to Universal Host to capture your voice in full audio bandwidth, while maintaining excellent separation between your voice and the caller.
Conference Rooms
Easily connect your PA system to the existing IP or PBX telephone system. The echo canceller algorithm prevents feedback and allow full duplex conversations.
USB CODEC
The 16 bit USB audio CODEC allows stereo recording at up to 48 kHz sampling rate, with the talent voice on the left channel in full bandwidth, and the caller on the right. Play recordings from your computer directly into the phone system.
