JK Audio AUTO AutoHybrid - Telephone Audio Interface

Professional Telephone Audio Interface

The JK Audio AutoHybrid is a compact and reliable telephone audio interface designed to connect standard telephone lines directly to your professional audio equipment. It provides a clean and balanced connection between analog phone calls and recording or broadcasting systems, making it ideal for studios, live events, and remote interviews. Built with simplicity in mind, the AutoHybrid offers all the essential features needed for seamless two-way communication without unnecessary complications.

Full Duplex Audio Performance

With its passive transformer-based hybrid design, the AutoHybrid ensures simultaneous two-way audio flow for both send and receive signals. This full duplex operation allows callers and hosts to interact naturally without disruptive delays or awkward cutoffs. The hybrid circuit also provides an impressive 20 dB reduction between the send audio level on the caller output and the transmit level, ensuring clear, professional-quality sound in every conversation.

Automatic Call Handling

Designed for convenience, the AutoHybrid includes an Auto-Answer function that can be enabled to automatically answer incoming calls on the first ring. Once the caller disconnects, the unit automatically drops the line, freeing up the interface for the next use. This feature is especially useful for broadcast stations, monitoring setups, and remote feeds where unattended operation is necessary.

User-Friendly Controls and Indicators

In addition to its automatic operation, the AutoHybrid provides manual Call and Drop buttons that let you connect or disconnect calls directly from the unit. An Off-Hook (OH) status indicator LED shows when the line is active, giving operators clear visual confirmation. The detachable screw terminal block allows for remote control access to all functions, making integration into larger systems smooth and efficient.

Rugged and Reliable Construction

Housed in a durable aluminum chassis, the JK Audio AutoHybrid is built to withstand the demands of daily use in both studio and field environments. The passive design means there are no active electronics to wear out or fail, ensuring long-lasting performance. Balanced XLR input and output connections further guarantee noise-free integration with mixers, recorders, or broadcast consoles.

Versatile Applications for Professionals

This telephone audio interface is widely used for radio and television interviews, IFB feeds, conference calls, podcasting, and other communication-critical environments. Whether you are connecting to a traditional landline or using it alongside cell phone adapters, the AutoHybrid provides a straightforward and effective solution for capturing high-quality telephone audio.
