CATALOG | ENGLISH 

Telephone Audio Interface Products

Over the years, we have updated and replaced 

many of our original models with new, compact, 

energy-efficient designs. You will be pleased to 

know that every product in this catalog is now 

RoHS and CE compliant. It has amazed us, as well as 

our vendors, just how resilient some of our designs 

have been. Take last year for example. After 17 

years of production we finally discontinued our 

popular RemoteMix C+ Broadcast Mixer. We just 

couldn't find the parts anymore! Within weeks, 

our customers let us know just how much they 

missed it. We quickly went to work designing a 

replacement that will withstand the next 17 years. 

So please check out our new RemoteMix 2. 

Another relatively timeless design from your 

friends at JK Audio.

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 jacks, 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 

Our new 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 new cable is now shipping with the 

following JK Audio products: Daptor Two, ComPack, 

RemoteMix Sport, RemoteMix 4, RemoteMix One, 

RemoteMix 3.5

AUTO-ANSWER HYBRIDS 

AutoHybrid 

Full Duplex Auto-Answer Hybrid 

Not just another half duplex auto-coupler. 

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.

Digital Auto-Answer Hybrid 

Go digital for more desirable quality. 

Compared to the AutoHybrid, the innkeeper LTD autoanswer/disconnect 

hybrid allows you to send line level 

signals into the phone line while maintaining greater 

separation between the talent's voice and the caller. 

The balanced XLR output jack contains only the caller’s 

voice, making this the perfect companion to mixers, 

consoles, and PA systems that demand talk show 

quality audio from a phone line. 

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.

A HYBRID FOR EVERY DESKTOP. 

Analog & Wireless/Cellular 

Turn your desktop into a professional broadcast center. Each 

Hybrid includes everything you need to get talk show quality 

phone recordings into your mixer or sound card with excellent 

caller separation. 

DESKTOP DIGITAL HYBRIDS 

Broadcasting Made Easy. 

Connect a mic and headphones for a simple broadcast 

back to the station. Already at the station Use a 

JK Audio Digital Hybrid in your newsroom to record 

high quality interviews. Or, you can upload your 

recorded interview to your podcast. JK Audio Digital 

Hybrids allows you to send mic and line level signals, 

at a higher quality than the phone's mic and speaker, 

into the phone line while maintaining excellent 

separation between your voice and the caller. 

Interviews: Connect a professional dynamic mic and 

headphones to a JK Audio digital hybrid to capture 

your voice in full audio bandwidth, while maintaining 

excellent separation between your voice and the caller 

Conference Room: Easily 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.

innkeeper 1x/1rx 

Digital Hybrid 

A Hybrid Jam-Packed with Features. 

This single-line hybrid is perfect for radio or television 

talk shows, teleconferencing, or auto-answer IFB 

feeds. From the front panel you can call, drop and 

adjust headphone volume. Front panel LEDs display 

signal levels and option status. The Send and Caller 

Volume controls and feature switches are hidden 

behind an access panel to prevent unauthorized 

“tweaking”. innkeeper 1x/1rx is compatible with 

Guest Module 1 and RIU-IP remote control interfaces. 

For Talk Show applications combine innkeeper 1x/1rx 

with the Concierge 2x6 Switch Core and Guest Module 

GM2x6 ( on page 21). 

Automatic Gain Control (AGC). Adjusts the caller 

volume to an average level. AGC will tame a loud 

caller, and boost a quiet caller or quiet long distance 

connection. 

Caller Ducking. Drops the Caller output level by 9 

dB whenever the host speaks. This keeps the host “in 

charge” of the show, automatically making sure the 

caller never overpowers the host by attempting to talk 

over the host’s voice. 

Presence. Press the “Presence” button to get a 

richer sound from the caller’s voice. This digital filter 

brings back some of the low-end lost in transmission. 

Remote Control. Control innkeeper 1x/1rx with 

the Guest Module 1, Screw Terminals, a RS-232 cable 

or the RIU-IP Remote IP Interface. See pg 17.

innkeeper 2 & 4 

Multi-Line Digital Hybrids 

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). 

Menu System. The front panel keypad, display, 

and handset jacks provide easy speed dialing and call 

setup. The menu driven keypad and back-lit display 

allows you to store 50 phone numbers by name in a 

phone list. You can also use the display to set features 

such as the number of rings before auto answer, 

master send channel selection, and test tone output. 

innkeeper 2 Conferencing. Innkeeper 2 has a 

convenient conference feature that joins two active 

phone calls together. Menu options determine how 

the conference is joined, providing several options to 

ease mix-minus setup. 

Remote Control. Control innkeeper 2/4 with the 

RIU-IP Remote IP Interface. See pg 17.

of your cables has gone rogue, it's time for field 

reporting that is a little more portable. Don't get 

wrapped up in unnecessary cables. BluePack allows 

live man-on-the-street interviews through a cell phone 

equipped with Bluetooth Wireless Technology. 

Wireless Phones and Notebooks: 

BluePack pairs to your cell phone like a Bluetooth 

wireless headset. BluePack also pairs to Bluetooth 

equipped sound cards and music players in full

bandwidth back to the station. However, this output 

allows you to make a full bandwidth recording to 

bring back to the station or send over the web.

while the mixer's XLR output is pre-limiter (full 

range). Convenient 3.5 mm send and receive jacks for 

recording the show, or mixing in your MP3 player. 

Exclusive to the RemoteMix 4, Bass Boost adds 

some low end before sending the signal down the 

phone line. 

Power Smart Design. Low noise, low power ICs 

are used throughout either of these mixers to preserve 

battery life. The low noise 100-240 VAC desktop style 

power supply (included) overrides the battery power 

only when the supply is actually providing power. If 

the power goes out, the batteries automatically cut 

in. The phantom power generator in the RemoteMix 4 

only runs if any of the rear panel 48 V switches are set 

to “ON”.

into ComPack. You can now send and receive audio 

through the PBX telephone set. 

Analog Phones. Plug ComPack into an RJ-11 jack, 

go off-hook and dial, or answer an incoming call. 

Add a Phone Line to the Party-Line. ComPack 

also functions as a simple telecom interface for your
