JK Audio UHOST Universal Host Desktop Digital Hybrid Telephone Interface

Professional Digital Hybrid for Broadcast and Recording

The JK Audio Universal Host is a desktop digital hybrid telephone interface designed for professional broadcasting, podcasting, and communication applications. It bridges the gap between telephones, microphones, headphones, and computer recording systems, making it an essential tool for capturing high-quality interviews, talk shows, and live conversations. With its built-in USB audio codec and DSP technology, it delivers clear, separated audio between the caller and the talent for seamless integration into modern production workflows.

Compatible with IP and PBX Telephone Systems

This device connects easily between the base and handset of most IP and PBX phones, allowing it to integrate into office or studio environments without complex installation. Once connected, it provides a direct path for recording calls or routing external audio into the phone line. Its compatibility makes it an excellent choice for broadcasters, journalists, and producers working across different telecom setups.

USB Audio Interface for High-Quality Recording

The Universal Host features a USB audio codec that supports 16-bit, 48kHz resolution. This enables professional-grade recordings directly to your computer while maintaining separation between your microphone and the caller. By assigning the host’s voice to the left channel and the caller’s voice to the right, the system makes post-production editing and mixing faster and more efficient.

Built-In DSP with Echo Cancellation

To ensure broadcast-quality performance, the Universal Host uses digital signal processing (DSP) that constantly monitors both incoming and outgoing signals. Its proprietary echo cancellation algorithm delivers clear separation without requiring manual setup or sending disruptive test tones. This ensures that both the caller and the talent sound clean and natural, even in challenging phone line conditions.

Flexible Connection Options for Studio Integration

The Universal Host provides multiple connection points, including microphone, headphone, mixer, sound card, and telephone jacks. The rear stereo output separates the talent and caller onto two channels, while the XLR output delivers only the caller’s audio. This flexibility makes it easy to integrate into broadcast studios, podcast setups, or production facilities where precise routing and signal control are essential.

Intuitive Controls for Easy Operation

Handset and Online buttons allow you to switch between speaking directly on the handset or through the Universal Host’s audio connections. An additional switch provides the option to monitor either the caller’s voice or the USB audio feed through headphones. This level of control ensures that users can manage their workflow efficiently without technical complexity.

Reliable Performance for Broadcast Professionals

Whether you are hosting live interviews, recording podcasts, or producing phone-based segments for radio or television, the Universal Host delivers consistent, high-quality performance. Its ability to combine telephony with digital audio tools makes it a dependable solution for professionals who require clarity, flexibility, and ease of use.
