ANNIVERSARY
2017 Marks 25 Years for JK Audio! “A lot has changed” would be an understatement, as we developed our unique place in the world of communications audio. While technology has certainly changed over the years, we adapted, bringing users the high quality and ease of use that you have come to expect from our products. As technology changes, new opportunities arise. Take our BlueDriver-F3 for example. Designed originally for the Radio reporter, this Bluetooth device has recently found its place as a wireless mic while shooting video on smart phones and tablets. While phone manufacturers “pull the 3.5 mm plug”, our Bluetooth HD Voice product line is enjoying a surge in applications. This year, we introduce Interchange LTD! Not only is it a combination of our top-selling Interchange and Innkeeper LTD, but we've added a common-sense keypad and a TRRS headset input for a quick call setup. Thank You for 25 years of trust!

Wireless Phone Compatibility
Many JK Audio products provide a connection to a wireless (cell) phone. While our interface cables plug directly into the headset/earpiece jack on many phone models, there are some phones that are designed to prevent operation with third party accessories. In most cases, if you can use a generic, third party headset with your cell phone, you can use your JK Audio product as well. Also, while some wireless phones have an acceptable 2.5 mm or 3.5 mm jack, others require a headset adapter to convert their proprietary connector to an acceptable jack. JK Audio does not offer these adapters.
Connect to Smart Phones
The CN113 adapter cable is now shipping with select JK Audio products. This four-conductor, 3.5 mm headset adapter cable is compatible with most iPhones, Android phones, and notebook computers. The CN113 adapter cable allows audio to be sent through the headset jack of these new phones and notebooks, allowing send and receive of voice band audio during regular calls, or full bandwidth audio using third party codec applications. This cable ships with Daptor Two, ComPack, RemoteMix One, RemoteMix 2, RemoteMix 3.5, RemoteMix 4, RemoteMix x4, Interchange and Interchange LTD.

QuickTap™
THAT-2™
Quick and Simple. QuickTap gives you an easy way to record telephone interviews to your portable recorder or even directly to your computer sound card to be uploaded to your podcast. For group listen applications, the Output jack can be connected to a powered speaker or PA system. This jack contains a nice mix of both sides of the conversation.
Handset Tap + Send Input. Connect the THAT-2 between your telephone and handset for quick access to audio in and out of the telephone. The THAT-2 is used by radio stations to record and play sound bites, and by TV and film sound crews to get IFB and dialog over phone lines.

CellTap 4C is an interview recording adapter that’s compatible with most smart phones, tablets, and notebooks that use the 4-conductor 3.5 mm TRRS headset jack. Connect CellTap 4C between the existing ear-bud headset and phone, and then connect the stereo output to a mic level input on your recorder or mixer. The transformer coupled stereo output provides the local mic on the left channel and the caller on the right channel. The local audio is a full bandwidth connection.

connect your PA system to the telephone system. The echo canceller algorithm prevents feedback and allow full duplex conversations.
Why a Digital Hybrid?
The main function of any hybrid is to bring in the caller’s voice from the phone line, as clear and clean as possible. In the real world, when you send your voice down the telephone line it has a tendency to bleed over into the caller’s audio. The hybrid must adapt to the phone line in order to properly separate transmit and receive audio. We use a 16-bit DSP to monitor the phone line and audio signals continuously in order to deliver excellent separation. Our dual-convergence echo canceller algorithm can achieve excellent transhybrid loss, typically exceeding 50 dB, without any setup and without sending a burst of noise into the phone line.

AutoHybrid™
Full Duplex Auto-Answer Hybrid Not just another half duplex auto-coupler.
AUTO-ANSWER HYBRIDS
This simple, passive, auto-answer/disconnect telephone line hybrid allows simultaneous send and receive audio through analog telephone lines. Suitable for monitoring remote locations, IFB feeds, and many simple studio, conferencing, and PA telephone interface applications.
Full Duplex. Yes, you can send and receive audio
at the same time. The dual transformer hybrid is capable of 20 dB nominal trans-hybrid loss. In other words, your transmit signal will appear mixed with the receive signal, but at a level 20 dB lower than it was sent into the phone line.
Auto-Answer. The "Auto" feature is very simple. When the "Auto" switch is selected, AutoHybrid will answer on the first ring. The phone line will remain off-hook, until either the Drop button is depressed, or until the phone company releases the line.

Guest Module 1™ Remote Keypad
This little time-saver gives you call control you simply can't get with an auxiliary telephone and a couple of switches. An 8 pin RJ45 modular cable provides remote power so there is no need for batteries or an external power pack. The Call button will flicker when a call comes in. Press this button to answer or place a call. The button will stay lit when a call is present. When you dial on-air, the tones go out on the line, and do not come back mixed with the dial tone or caller signal.

16-bit DSP Technology. The digital hybrid connects audio signals to a standard analog telephone line without the transmit / receive crosstalk common to analog hybrids. Its Digital Signal Processor (DSP) continuously monitors both the phone line and audio signals to deliver excellent separation. This proprietary, dual-convergence echo canceller algorithm can achieve excellent separation, typically exceeding 50 dB, without any setup and without sending a noise burst down the line. While this may sound complicated, it’s all done automatically during every call.

1rx Input Female XLR:
When a Single Line Hybrid Isn't Enough.
Innkeeper 2 / innkeeper 4 squeeze two/four independent digital hybrids in a 1U rack space to extract each caller's voice into separate channels. Each phone line has an individual send and receive XLR jack. While this should be enough for most applications, there are several applications that require a “Master” audio input. This additional XLR input mixes with the audio of the individual channel send jacks. By default, the master input will mix into all four channels. The front panel menu system allows you to turn off the master signal from any or all phone lines. For Talk Show applications combine innkeeper 2 with the Concierge 2x6 Switch Core and Guest Module GM2x6 ( on page 21).

The Listen-Always design allows both the phone hybrid / 4-wire connection and the cell phone headset interface to monitor the intercom just like any other belt pack. Listen mode is a high impedance bridging tap on the intercom line. Talk mode is enabled via a front panel switch, either Off, On, or Auto. Auto follows the phone hybrid AutoAnswer mode. Talk mode uses a solid state relay to properly couple Talk audio from the phone line and cell phone interfaces, to the intercom channel.
The Innkeeper 2 conference feature allows two callers to share one intercom connection. Alternatively, the included cables allow Line 1 and Line 2 of the Innkeeper 2 to be connected to two separate Interchange™ units, allowing connection to separate intercom loops.

The front panel headset interface jack allows easy connection to your wireless phone, tablet, or computer allowing remote access through a phone call or conferencing app. The front panel DTMF keypad and 3.5 mm TRRS headset jack allow easy call setup. The internal digital hybrid connects intercom audio to a standard analog telephone line without the transmit/receive crosstalk common to analog hybrids. Its DSP continuously monitors both the phone line and audio signals to deliver excellent separation. This proprietary, dual-convergence echo canceller algorithm can achieve excellent separation, typically exceeding 50 dB, without any setup and without sending a noise burst down the line.
