I was watching the evening news as they cut to a locker room interview. A few years ago you would have seen a dozen hands holding microphones with radio and television station logos.

While the TV mics are clearly visible, the radio station identity has been lost in a sea of handheld digital recorders. One might argue that the subject of the interview might even respond differently if they were speaking into a “live” mic versus a recorder.

The talent holding the microphone is what separates the amateur reporter from the veteran.

Don’t get lost in a sea of recorders. Stand proud with your microphone in hand, connected to your JK Audio BluePack, sending live audio to the station while capturing the moment on your favorite (out of sight) recorder.

For our friends in the ENG truck, you’ve got to check out RemoteAmp Blue for those last minute, “grab the camera”, no time for IFB moments. We offer a true

IFB connection from your Bluetooth equipped cell phone. Go ahead, place a camera down the street using a cell phone for quick IFB.

Wireless Phone Compatibility...

Many JK Audio products provide connection to wireless (cell) phones. While our interface cable plugs directly into the 2.5 mm headset/ earpiece jack on many telephone models, there are some telephones that are wired to prevent operation with third party equipment. 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 jack, others require a headset adapter to convert their proprietary connector to an acceptable 2.5 mm jack.

JK Audio does not offer these adapters.

Warranty

JK Audio products are covered by a two year warranty to be free from defective workmanship and materials. In the event that your JK Audio product needs repair, you must call us to get an authorization, and then carefully pack and ship it to us or the nearest authorized repair center. You will pay for shipping to us and we will pay for return back to you. No free repairs will be made if the defect was caused by misuse, weather conditions, or other causes, except for defective workmanship or materials. There are no expressed or implied warranties which extend beyond the warranty here made. Prices, features, and specifications subject to change without notice.

Wireless Technology

JK Audio is proud to offer a line of new products that utilize Bluetooth

Wireless Technology. These products offer seamless integration with your Bluetooth-enabled audio devices, such as cell phones and notebook computers.

While Bluetooth has become a common term, many people think of it in terms of the lightweight headset that is used to enable hands-free communication with a cell phone. While this tiny headset has freed our hands from the phone, there are many low cost (wired or wireless) headsets that have lowered the audio quality of an already challenging cell phone connection. There may be a misconception that Bluetooth Wireless Technology is to blame for these less than intelligible conversations. We’re here to tell you that this is not true. Bluetooth wireless technology is used with wireless, full bandwidth headphones without static or interruption.

Our wireless products use a rock-solid, full fidelity codec to digitize the audio stream and send it to the cell phone, where it remains a digital signal all the way through the phone network. Using your professional microphone and headphones, along with our low noise mic preamp and headphone amplifier allow a vast improvement over any cell phone or handsfree headset.

The Bluetooth word mark and logos are owned by the Bluetooth SIG, Inc. and any use of such marks by JK Audio, Inc. is under license. Other trademarks and trade names are those of their respective owners.

RemoteMix 4

RemoteMix 4 is a four channel field mixer combined with a four channel headphone amplifier. It includes a phone line hybrid and keypad, as well as a universal PBX handset interface and a 2.5mm wireless phone interface. It can also connect to cell phones and portables using Bluetooth

®

Wireless Technology. All this in a tough, portable unit that's smaller than a lunch box. All-in-one is an understatement. These parts were designed to work together and save setup time in the field. No need to send an engineer with patch cables. All the pieces work together in one reliable unit.

Radio

RemoteMix 4 was designed for sports remotes. Use it as a phone line hybrid, calling into your studio talk show hybrid. Use it as a front end mixer for your POTS, ISDN or IP codec. Use it with your laptop codec.

TV

RemoteMix 4 gives you the ultimate phone connectivity with four IFB feeds. Imagine being able to send and receive interview audio, and pull

IFB out of any business phone system, even your cell phone. More than a field mixer, this is a shoot saver.

Great Sound

A soft limiter prevents overdriving the phone line interfaces, while the mixer XLR output is pre-limiter (full range). Bass Boost adds some low end before sending the signal down the phone line. Convenient

3.5 mm send and receive jacks for recording the show, or mixing in your MP3 player.

Power Smart Design

Phantom power is not always needed, yet it can be a real drain on batteries. The phantom power generator only runs if any of the rear panel 48 V switches are set to “ON”. Low noise, low power ICs are used throughout 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.

Telephone Audio Interface

Autohybrid

AutoHybrid allows simultaneous send and receive audio through analog telephone lines.

This is a simple, passive, auto-answer/disconnect telephone line hybrid. Not just another half duplex auto-coupler, this is a full duplex

AutoHybrid. Perfect for monitoring remote locations, IFB feeds, and many simple studio, conferencing, and PA telephone interface applications.

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.

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, or seized, until either the Drop button is depressed, or until the phone company releases the line. AutoHybrid will drop the line with either a momentary loss of line current or a polarity reversal. Keep in mind that it may take several seconds before the phone company provides this release signal. Also keep in mind that some business PBX telephone systems do not provide this release signal.

This small desktop unit easily converts to a rack-mount unit using the optional RA4 Rack

Panel. The RA4 holds four AutoHybrids in a 1U rack space.

Telephone Audio Interface

Inline Patch

This unique hybrid works with your telephone to give you more control over interview recording and playback.

The Inline Patch is a little box that connects between the base of an analog or cordless telephone and the wall jack. You can continue to talk on the phone and get access to audio on both sides of the call. The unit’s two back-to-back hybrids give you complete control of audio from both sides of the call. Audio input jacks let you mix sound bytes or music into your conversation.

One stereo output jack provides your voice on one channel and the caller’s voice on the other channel. A second output jack contains a mix of both voices. Front-panel control for each output offers all the control you will need. The Inline Patch will not disrupt your

Caller ID or ring signals.

For telecom demo or teleconference presentations, you can use a cordless telephone. Walk around the room and talk over the phone while everyone listens in. Let the audience try your IVR application.

The Off Hook/Normal switch lets you seize a phone line without using a telephone. This switch can be remote-controlled with a simple contact closure.

The Inline Patch is also perfect for television or cable talk show use, when you may need access to audio from a working telephone on camera.

innkeeper 1x

innkeeper 1x and 1rx

The innkeeper 1x gets audio in and out of analog telephone lines. Its excellent caller audio output does not exhibit the transmit/receive crosstalk common to analog hybrids. This makes innkeeper

1x perfect for radio or television talk shows, teleconferencing, or auto-answer IFB feeds.

Innkeeper 1x connects audio signals to a standard analog telephone line without the variations in quality found with analog hybrids. The main function of a 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 algorithm can achieve trans-hybrid loss, typically exceeding 50 dB, without any setup.

From the front panel you can control on-hook/offhook, and adjust headphone volume. Front-panel

LEDs display signal levels and option status.

The Send and Caller Volume controls are hidden behind an access panel to discourage unauthorized “tweaking”. Five feature switches are also hidden behind the access panel. AGC (Automatic

Gain Control) 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. Press the “Presence” button and you’ll get a richer sound from the caller’s voice. This digital filter brings back some of the low-end lost in transmission. The Test Tone generator sends a

1 kHz full level tone either down the phone line or out the Caller XLR jack. This tone represents the maximum level transmit into the phone line or out the XLR jacks. The Test Tone generator is not required for tuning the digital hybrid. Auto-

Answer simply answers on the first ring and disconnects at the end of the call.

This wouldn’t be a JK Audio product without its fill of common-sense features. Check out the front-panel headphone jack and volume control.

You can monitor either the send signal, the caller’s voice, or a mix of the two. This output is also sent to the rear panel screw terminals so you can easily add a monitor speaker. As a matter of fact, several remote control connections can be found on real screw terminals for ease of installation. Three balanced audio connections:

Guest Module 1 to your Broadcast Host and innkeeper 1 series digital hybrid using an 8 pin RJ45 modular cable. This 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.

About Digital Hybrids

Digital Hybrid

The purpose of a hybrid is to allow you to send and receive audio through a telephone line. The quality of the hybrid determines the amount of transmit audio that appears on the receive output jack, mixed with the caller’s voice. We use a proprietary dual-convergence echo canceller algorithm which continuously compares transmit and receive audio while building a model of the phone line. The first model is built within the first 200 milliseconds of the call. Afterwards, the algorithm continuously adapts to the phone line for the duration of the call. This system is not disturbed by changes such as someone taking an extension phone off-hook. Only your audio source is used as input to the algorithm. It does not require any noise bursts or “quiet time” to complete its mission. Bottom Line... Excellent separation all the time.

Functions of the innkeeper 2 and 4

Master Send

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 jack. 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.

Keypad Dialing

Don’t let the display and cursor keys scare you.

If you need to place a call, just press the Call button on any line, then start dialing. To “hang up” simply press Drop.

Remote Control

Included with your innkeeper 4 is a small terminal board with a

5 foot cable that attaches to the remote jack on the back panel.

This terminal block contains two pins for each phone line. One pin provides Off Hook indication which supplies current to a remote LED when the line is active. The second pin is for a remote toggle switch to take the corresponding line off or on hook.

This remote jack also connects to our model

RIU-IP web server providing remote control from anywhere in the world.

Menu System

The cursor keys guide you through several features including speed dialing, test tone generation, Auto-Answer ring count, and

Master Send line muting. Speed dial list includes phone numbers referenced by an alpha text name such as “Bob Smith”. Test tone generation allows you to send a 1 kHz signal down any phone line or out any Caller output jack. This signal allows you to set levels on your existing audio equipment. Test signals are not a part of the auto-null tuning algorithm. Auto-

Answer can be set to pick up after 0-7 rings

(0 = never answer).

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, proving several option to ease mix-minus setup.

Portable Remote Mixer

High quality audio connectors clearly labeled for quick setup.

Universal PBX interface with 3 position handset type switch.

RemoteMix 3

The RemoteMix 3 is a combined Phone Line

Hybrid Mixer and Universal Handset Interface in one! We combined an audio mixer, headphone amplifier, telephone hybrid, and PBX telephone interface in one rugged unit. It’s perfect for remote broadcasts, sport events, and field reporting from any location.

Simply plug the RemoteMix 3 into an analog phone line, connect a couple of microphones and headphones, and you’re ready to call into the station. In your headphones, you will hear a mix of both microphones and the line in jack, as well as the audio coming back from the other side of the phone call. This headphone mix also comes out of the back of the unit on an RCA jack and an XLR balanced jack, which are adjustable from line level to mic level for

PA system or tape deck feeds. The built-in time-delayed peak limiter and VU meter help to control transmit levels, while the built-in push-to-talk condenser microphone and monitor speaker are a real help during equipment set-up and station breaks.

Universal Handset Interface?

Did you ever get to a remote site where the location manager hands you a PBX telephone and says “Here’s your phone, use line 3....”. Well, now you can! Simply unplug the handset from the phone and plug the coily cord directly into the PBX jack on the RemoteMix 3, then select the type of handset that was on the phone. The

RemoteMix 3 has a 3 position switch which will accommodate electret, dynamic, and carbon handset microphone types. It will emulate the type of microphone that was in the handset and allow you to use your professional microphones and headphones during the broadcast. Its three settings cover most analog and digital PBX sets as well as ISDN sets.

Wireless Phone Interface

Daptor One

Remote Broadcasts over a cell phone? Daptor

One converts the 2.5mm headset jack on your wireless cellular phone to a modular phone line jack. This modular RJ11 jack connects directly to any JK Audio RemoteMix series mixer or any JK

Audio innkeeper 1x Digital Hybrid.

Daptor One was designed to take advantage of the increasing number of wireless phones that accept third party headsets and earpiece headsets. We’ve designed a circuit which emulates the electrical characteristics of these headsets. Daptor

One will work with all wireless phones that accept generic third party headsets. Please see Wireless

Phone Compatibility on page 2. Daptor One contains a mini hybrid circuit that converts these earpiece and microphone signals into a balanced

RJ11 phone line signal. The mic signals from the

RemoteMix are sent into the wireless phone, while the earpiece signals from the wireless phone are sent into the RemoteMix Headphones. The hybrid circuit minimizes cross talk between transmit and receive which would create unwanted echo on both the RemoteMix and far side of the call. You will continue to use your wireless phone to dial or answer the call, but you will use the microphones and headphones plugged into your RemoteMix during the call.

Daptor One does not supply the necessary ring voltage or talk battery which may be required by modems or other manufacturer’ s remote consoles.

Pureformer

The Pureformer provides hum and noise reduction for sound cards and audio equipment, and removes ground loops and DC paths that can cause hum and signal breakup.

The Pureformer isolates the electrical grounds of two pieces of audio equipment. This is especially important in the case of computer audio cards connected to high quality/low noise audio equipment. The computer electrical ground is often filled with noise from disk drive activity and data transmission. Many audio cards use the same electrical ground for the computer and the audio

Telephone Audio and Power Interface

TAP-1

The TAP-1 is a phone line simulator for simple audio applications, that powers an analog telephone with the required –48 volts DC and separates audio into transmit and receive audio paths. The

TAP-1 acts like an RJ-11 wall jack in your home.

You may not know it, but the telephone company sends power down into your wall jack, and you use it to power your phone. This power is sent over the two wires called Tip and Ring. These two wires form a balanced, two-way voice path which can be sent miles with minimal noise and signal loss.

This two-wire interface can be a burden if you just want to get audio in and out of a telephone without connection to the telephone company.

The TAP-1 provides the Tip/Ring interface and

–48 volt supply and then separates audio into transmit and receive. This is called a 2-wire to

4-wire hybrid. The bottom line... the TAP-1 can be used on TV or film studio sets where a telephone or cordless telephone is used on set and you want to get audio into and out of the telephone. You can also use the TAP-1 to test telephones, voice coding algorithms, or phone line equipment. The

TAP-1 is built to very high specs for laboratory testing use.
