JK Audio Inline Patch Telephone Audio Recorder Interface
Key Features
  • Record or Amplify Phone Calls
  • RJ11C Phone Connection
  • Hybrid Circuitry
  • XLR and 3.5mm Connectors
The JK Audio Inline Patch Telephone Audio Recorder Interface is an interface patch between telephone lines and audio devices such as speakers, amplifiers and recorders. The idea behind the Inline Patch is to provide a simple solution for anyone who requires a phone tap for the purpose of recording or amplifying telephone conversations. The Inline Patch connects between the telephone wall jack and the base of any analog or cordless telephone requiring standard RJ11C telephone cable.

Full duplex communication between the talkers is captured with great accuracy and hybrid circuitry provides a nominal 20dB of signal isolation between the transmit and receive signals. This minimizes the noise and cross-talk associated with audio over phone lines. Balanced XLR and unbalanced 1/8" (3.5mm) Send To Phone inputs allow line level audio to be fed over the phone line. A balanced XLR output isolates incoming signal from the phone line. A pair of additional 3.5mm mini outputs provide a stereo (isolated left/right) or mono mix of send, receive and line level audio signal.

Inline Operation

The Inline Patch is a simple, effective solution for recording or capturing audio over phone lines. The Inline Patch connects between a wall jack and analog or cordless telephone base.

Flexible Routing

XLR and 3.5mm mini line level inputs provide line level signal feeds over phone lines. A line level XLR output provides an isolated output for incoming signal while a pair of 3.5mm outputs provide a stereo and mono mix of both line and send / receive signals.

Suitable for Demo or Teleconference Presentation

The Inline Patch is suitable for connecting to powered speakers and using a cordless phone as a wireless intercom device for presentation and teleconferencing application.

Comprehensive Controls

The front panel features level control of send and receive telephone signal as well as line level signal. A Separation dial adjust the amount of isolation between send and receive signals.

Hybrid Technology

Hybrid circuitry provides a nominal 20dB of signal isolation between the transmit and receive signals. This minimizes the noise and cross-talk associated with audio over phone lines.

question

Can this unit isolate one side of the conversation? When recording conversations in a meeting setting (depositions) a speaker phone is used for telephonic appearances. Can I isolate the out going side of the conversation seeing as I already have mics on these folks?
Asked by: Eric H.
The unit will split the audio, one channel allowing the recording of one side of the conversation, the other channel records the other side. You need to adjust the levels of each channel before recording by testing the output. But there is a small amount of bleed-through, the audio is about 85% or so, I'd say, clean. But if no one is speaking over the the person being interviewed, it is not a problem. I found the unit quite useful for interviewing.
