JK Audio INNPBX innkeeper PBX Digital Hybrid for PBX and VoIP Handset Lines

Multi-line office phones become an affordable talk-show console with the JK Audio innkeeper PBX, the Broadcast Host for PBX phone lines. It connects between the telephone handset and the phone base, passing audio through the handset cord, so it works where there is no analog line available.

Connections for a microphone, headphones, mixer, sound card, and handset are all on board. The balanced XLR output carries only the caller, the stereo output puts your voice on one channel and the caller on the other, and Handset and Broadcast buttons switch between talking on the handset and sending and receiving through the audio connections.

The DSP echo canceller typically exceeds 50 dB of separation with no setup, and a selector matches electret, carbon, or dynamic handsets. Hosts can take callers on air while a producer screens on another phone, newsrooms can record interviews, and conference rooms can tie a PA into the PBX for full-duplex calls.
