Simple and effective

This little box has just 3 buttons but that's enough for it to do a great job. As a VO Talent I needed a phone-patch solution and the JK Audio works wonderfully and its simplicity is great. Recommended!

Because communication is key in any professional setting, the JK Audio AutoHybrid Full Duplex Auto Answer Telephone Audio Interface stands out as an essential tool for seamless audio interfacing through analog telephone lines. This innovative device is not your standard half-duplex auto-coupler; it is an advanced full duplex AutoHybrid, allowing for simultaneous sending and receiving of audio without interruption.

Crafted with durability and high-quality components, the AutoHybrid boasts a dual transformer hybrid capable of achieving a 20 dB nominal trans-hybrid loss. This means that your transmitted signal will be seamlessly integrated with the incoming signal, but at a level 20 dB lower than it was sent, ensuring clear and professional audio quality for your listeners.

The user-friendly "Auto" feature simplifies operation to the utmost. With a simple switch selection, the AutoHybrid engages its auto-answer capability, picking up calls on the first ring and maintaining the line off-hook until you decide to disconnect by pressing the Drop button or until the phone company signals to release the line. However, it's important to note that some business PBX systems may not provide this release signal.

This compact unit is not only perfect for monitoring remote locations and providing IFB feeds but also excels in various applications such as simple studio setups, conferencing, and public address telephone interfaces. Despite its small size, the AutoHybrid contains all the necessary features for many straightforward applications.

For those looking to integrate this device into a more extensive setup, the AutoHybrid can be effortlessly converted into a rack-mount unit using the optional RA4 Rack Panel. The RA4 is designed to accommodate four AutoHybrids in a single 1U rack space, optimizing your workspace with a refined and professional appearance.

Choose the JK Audio AutoHybrid Full Duplex Auto Answer Telephone Audio Interface for its advanced, high-quality audio capabilities and user-friendly design. With its full duplex functionality and robust build, this interface is a top choice for professionals seeking reliable and innovative solutions in audio communication.
