JK Audio INNPBX Innkeeper PBX Digital Hybrid Multi-Line Telephone Converter

Digital Hybrid Telephone Interface for Broadcast Applications

The JK Audio Innkeeper PBX is a professional-grade telephone audio interface that transforms multi-line PBX, ISDN, or analog telephones into broadcast-ready communication tools. By connecting between the handset and the base of the phone, it allows incoming calls to be monitored, screened, and routed through professional audio equipment for on-air or recorded use. This makes it an essential solution for radio stations, talk shows, and production environments that rely on clean, reliable phone audio.

Talk Show Style Control for Live Broadcasts

One of the standout features of the Innkeeper PBX is its Broadcast mode. By pressing the front panel Broadcast button, the handset is disabled and the audio signal is instead routed through the XLR Send input, creating a talk show-style setup. This allows hosts to manage phone calls seamlessly while maintaining broadcast-quality audio, ensuring that live programming runs smoothly and professionally.

Advanced DSP Processing for Clean Audio

The unit uses 16-bit digital signal processing to eliminate the bleed and crosstalk that often occur with phone connections. This ensures that both incoming and outgoing audio remain cleanly separated, providing clarity for both the talent and the caller. With this level of processing, the Innkeeper PBX delivers dependable, high-quality phone audio that meets the standards of professional broadcast environments.

Flexible Input Options for Microphones and Consoles

The Innkeeper PBX is equipped with both balanced XLR and 3.5mm mini Send inputs, giving users the ability to connect microphones, mixing consoles, or other audio sources directly. The XLR input includes a mic/line switch, allowing users to adapt quickly between microphone-level and line-level signals. This versatility ensures compatibility with a wide range of equipment setups.

Caller and Send Level Control with Visual Monitoring

On the front panel, individual level controls are provided for Send 1, Send 2, and Caller audio, allowing precise adjustments during live operation. To aid in monitoring, 3-segment LED meters display both Send and Caller levels, giving operators a clear visual reference of their audio balance in real time.

Headphone Monitoring and Secondary Output Options

A front-panel 3.5mm stereo headphone jack provides direct monitoring with an independent level control. This jack can also be used to send a stereo mix to recorders, amplifiers, or external monitoring systems. The additional 3.5mm mini output ensures flexibility for capturing or distributing audio beyond the main XLR outputs.

Built for Professional Broadcast and Production

Designed with broadcasters and production teams in mind, the Innkeeper PBX combines rugged construction with advanced digital processing and flexible connectivity. Its ability to integrate into multi-line phone systems while delivering clear, broadcast-ready audio makes it a valuable tool for talk shows, live radio, podcasting, and television production.
