About JK Audio Innkeeper PBX

If you're looking to transform your multi-line PBX type telephone system into a professional-grade talk show console, the Jk Audio Innkeeper PBX Digital Hybrid Multi-Line Telephone Interface is your perfect solution. This innovative device seamlessly integrates between your telephone handset and the phone base, enabling a smooth transition from a standard telephone system to a high-quality broadcasting platform.

In a talk show setting, the Innkeeper PBX acts as a bridge between your console and your existing multi-line telephone. This feature allows your producer to screen callers from a separate phone while you engage with on-air callers, simply by selecting available lines on your phone. This streamlined process ensures a smooth and professional broadcast experience.

For journalists and podcasters, the Innkeeper PBX is an invaluable tool for recording high-quality interviews directly from your newsroom. Simply connect a microphone and headphones to your PBX telephone to maintain excellent voice separation between you and your interviewee. Once your interview is recorded, it's easy to upload to your podcast or other broadcasting platform.

In a conference room setting, the Innkeeper PBX effortlessly connects your PA system to your existing PBX telephone system. Its advanced echo canceller algorithm prevents feedback, enabling full duplex conversations without any setup or noise bursts down the line.

The Innkeeper PBX is equipped with a Digital Signal Processor (DSP) that continuously monitors both transmit and receive audio signals, ensuring excellent voice separation. It also 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 the caller's voice on the other, while the balanced XLR output jack contains only the caller's voice. With the Handset and Broadcast buttons, you can easily switch between talking on the handset or sending and receiving through the audio connections.

In summary, the Jk Audio Innkeeper PBX Digital Hybrid Multi-Line Telephone Interface is a versatile and professional solution for anyone looking to enhance their broadcasting capabilities.
