Overview

Introducing the AutoHybrid.

The JK Audio AutoHybrid is a simple, passive, auto-answer / disconnect
telephone line hybrid. AutoHybrid allows simultaneous send and receive audio
through analog telephone lines. Not just another half duplex auto-coupler, this
is a full duplex AutoHybrid. Perfect for remote monitoring, IFB feeds, and many
simple studio, conferencing, and PA telephone interface applications.

AutoHybrid's dual transformer hybrid circuit provides a nominal 20 dB separation
of send and receive audio. This means that the level of your send audio on the
caller output jack will be approximately 20 dB less than your transmit level.

Balanced XLR input and output jacks provide easy connection to your
professional audio equipment and the detachable screw terminal block provides
easy access to remote features.
