JK Audio Innkeeper PBX Digital Hybrid Broadcast Phone Handset Audio Interface

Near Mint Cosmetic Condition • Tested/Guaranteed • 115V/230V Power • Connects Between Phone and Handset for Bi-directional Broadcast Audio

Very lightly used and in close to mint cosmetic condition.  It includes the accessories as shown. This hybrid connects between the Telephone and the Handset, and not between the phone and the wall jack. That way it doesn't matter whether the phone is analog, digital, VoIP or whatever. The power supply accepts both 115V and 230V AC. Note that JK Hybrids in my experience operate best with a low level of input signal, so start testing by turning down the Send gain control to the point where just the first LED level indicator is peaking lit.

Talk Show: Connect Innkeeper PBX between your console and your existing multi-line telephone. Your producer can screen callers from another phone while you take callers on the air by simply selecting available lines on your phone.

Interviews: Use Innkeeper PBX in your newsroom to record high quality interviews. Connect a mic and headphones to your PBX telephone while maintaining excellent separation between your voice and the caller. You can upload your recorded interview to your podcast.

Conference Room: Easily connect your PA system to the existing PBX telephone system. The echo canceller algorithm can prevent feedback and allow full duplex conversations.

The digital hybrid connects audio signals to your PBX type telephone system through the telephone handset cord. The Digital Signal Processor (DSP) continuously monitors both transmit and receive audio signals to deliver excellent separation. This proprietary, dual-convergence echo canceller algorithm can achieve excellent separation without any setup, and without sending a noise burst down the line.

Innkeeper PBX 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 Broadcast buttons select between talking on the handset, or sending and receiving through the audio connections.
