JK Audio AUTO Overview

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.

can i use this rig with an Apple iPhone XS to then connect a phone call through a mixing board for an audio podcast?
Asked by: Rick
The JK Audio AutoHybrid is a telephone audio interface, specifically for an old-fashioned landline, and will not work with a smartphone. I would recommend the JK Audio Daptor Three Bluetooth Cell Phone Audio Interface, B&H # JKDAP3, which can be connected to your iPhone through a 3,5mm cable or Bluetooth wireless, and can be inputted into your mixer. There is also a LINE IN on the unit, so you can send the signal back to the caller. You would require a mixer with and AUX Out feature.

I'm looking for a way to input a voice message, which has been processed in iZotope software, onto a standard answering machine, with the goal of having a clean outgoing message. Is the JK Audio AutoHybrid interface the way to achieve this? If not, what device would do the job? Thanks....
Asked by: John
This should work for your proposed application.

question

I would like to use this device to make engineering test measurements of signals on the POTS phone line (noise, distortion, frequency response, etc.). Are the audio signal levels on the XLR connectors the same as one would measure on the POTS line (w/o the DC of course)? And can both directions of two-way conversation be measured with this device?

Asked by: Simon
The AutoHybrid is a passive telephone audio interface, allowing a telephone signal to be brought into a mixing board as an audio signal, and then separating the caller and sender of the call. Typical use is radio call-in shows, podcasts and conferences.

question

I would like to know if this unit does its own mix minus. I intend to use it with a sound device 302 so no auxiliary sends are available.thanks
Asked by: Anonymous
The JK Audio Auto Hybrid is a basic passive telephone interface. It features a line level input and output on XLR. It will need to be sent a mix-minus signal as there is no control on the unit itself.

question

I have a multi line LG Ipecs phone system and want an interface for radio interviews. Is this the unit that will do it?
Asked by: Elliot K.
No. This requires a POTS line.

question

I have had this unit for a few years; loved it in the beginning, but then....people (on the other end) would have trouble hearing me. Maybe it's my phone line. I have it plugged in to my Mackie 1402- VLZ Pro mixer and I'm told that there's an echo (that mix minus thing..I'm guessing). What can I do to remedy that?
Asked by: Richard B.
You can get a mix minus from an aux bus. Send the aux to the hybrid and pot up everything but the hybrid on that aux bus.
