JK Audio INNLTD Innkeeper LTD Digital Hybrid - Telephone Audio Interface

Digital Hybrid Interface for Professional Phone Calls

The JK Audio Innkeeper LTD is a desktop digital hybrid designed to provide clear, broadcast-quality phone audio for radio, podcasting, live sound, and production. By separating the caller’s voice from the local talent microphone, it delivers a clean audio feed that can be routed through a mixing console or recording system. This makes it an essential tool for studios that regularly integrate phone calls into their programming or productions.

Clear Separation of Caller and Talent Audio

The Innkeeper LTD isolates the caller’s audio on a dedicated balanced XLR output, while a line-level signal can be sent into the phone line from your audio system. This separation ensures clarity during interviews, live call-ins, and remote contributions. Unlike basic phone patches, this hybrid prevents bleed-through, crosstalk, and echo, giving engineers full control over both sides of the conversation.

Advanced DSP for Echo and Noise Control

With built-in 16-bit digital signal processing, the Innkeeper LTD automatically applies echo cancellation and line noise reduction. Its proprietary auto-null algorithm provides up to 50 dB of isolation between signals, ensuring that the local microphone and caller audio remain distinct and free from feedback. This level of processing is critical for maintaining professional sound quality in live broadcast situations.

Flexible Setup with Mixing Consoles and Accessories

Designed for professional integration, the Innkeeper LTD accepts line-level signals as its primary input, making it ideal for use with mixers or mic preamps. Outgoing calls can be placed through a telephone connected to its auxiliary input, or controlled remotely with the optional JK Audio Guest Module 1. Its design allows it to adapt seamlessly into studio setups or mobile production rigs.

Easy Call Handling and Monitoring

User-friendly controls make call management simple. The unit can answer calls automatically or manually with the front-panel Call button, while a Drop button ends the call instantly. Three-segment LED meters provide clear visual monitoring of output levels, giving operators precise control over the audio feed.

Professional Connections for Broadcast Applications

The Innkeeper LTD includes balanced XLR connectors for send and receive audio, along with standard RJ-11 jacks for line and auxiliary phone connections. A remote control jack allows connection to external control modules, providing added convenience in larger studio environments. For permanent installations, the unit can also be rack-mounted.

Reliable Build for Studio and Field Use

Engineered for professional use, the Innkeeper LTD is housed in a durable desktop chassis that stands up to daily operation. Its combination of advanced DSP processing, professional-grade connectors, and flexible configuration makes it a trusted choice for broadcasters, podcasters, and live sound engineers who need dependable phone hybrid performance.
