JK Audio HOST Broadcast Host Desktop Digital Telephone Hybrid

Talk-show quality phone audio from a desktop box: the JK Audio Broadcast Host turns an analog phone line into a professional broadcast center, with everything needed to get clean phone recordings into a mixer or sound card. Connect a mic and headphones for a simple broadcast back to the station, or use it in the newsroom to record interviews for air or podcast.

Its DSP digital hybrid uses a proprietary dual-convergence echo canceller that typically achieves more than 50 dB of separation between your voice and the caller, without setup and without sending a noise burst down the line. The balanced XLR output carries only the caller, while the rear stereo output puts your voice on one channel and the caller on the other.

Send inputs include a balanced XLR with mic/line switch plus 3.5 mm line inputs, and send and caller level LEDs and volume controls keep levels in check. Auto-Answer/Auto-Disconnect supports IFB and monitoring, and the optional Guest Module 1 remote keypad can replace the auxiliary phone for call control.
