The JK Audio AutoHybrid is a simple passive telephone audio interface designed for IFB feeds, remote monitoring, conferencing, broadcast and studio recording applications. The AutoHybrid allows simultaneous send / receive audio flow through standard telephone lines. Balanced XLR input and output jacks allow noise free connection to pro audio recorders, mixers, amplifiers etc.

When enabled, the Auto-Answer feature will automatically answer an incoming call on the first ring and then disconnect after the caller hangs up. Additional controls include Call Button, Drop Button and OH (Off-Hook) status indicator LED. The dual transformer hybrid circuit results in a 20dB reduction between the send audio level on the caller output and the transmit level. A detachable screw terminal block provides remote control access to all features.
