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 con-
versations. 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
hands-free 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

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.

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

Desktop Digital Hybrid
Broadcast Host
Broadcast Host turns your desktop into a professional broadcast center. Contains everything you need to get talk show quality phone
recordings into your mixer or sound card.
Connect a mic and headphones for a simple
broadcast back to the station. Already at
the station? Use Broadcast Host in your
newsroom to record high quality interviews.
Broadcast Host allows you to send mic and
line level signals into the phone line while
maintaining excellent separation between your
voice and the caller. The stereo output jack on
the back of the unit provides your voice on
one channel and only the caller’s voice on the
other channel. The balanced XLR output jack
contains only the caller’s voice.
The digital hybrid connects audio signals to
a standard analog telephone line without the
transmit / receive crosstalk common to analog
hybrids. The 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.
Broadcast Host provides connections for a
microphone, headphones, mixer, sound card,
telephone and your analog telephone line. An
auxiliary telephone is only required to place
outgoing calls. The auxiliary telephone is disconnected when you press the “Call” button, and
reconnected when you press the “Drop” button.
Broadcast Host features Auto-Answer/
Auto Disconnect for use in IFB and monitoring applications. Other applications include:
Podcasting/telephone interviews, talk shows,
church PA interface, and conference room full
duplex applications.

Digital Hybrid
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/
off-hook, and adjust headphone volume. Frontpanel 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:

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.
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.
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.
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. AutoAnswer 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.

THAT-2
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.
The THAT-2 is the big brother of our model
THAT-1, which is very popular with news reporters for its small yet rugged design. Over the
years we’ve heard from many of our customers
that they liked the THAT-1 but would prefer professional XLR jacks and compatibility with more
telephone systems. Here is our answer... The
THAT-2, a passive handset interface with professional and consumer jacks, separate input
and output volume control, a selector switch for
the different types of telephone systems, and
still no batteries or AC needed!
Simply unplug the handset coily cord from the
base of your telephone and plug it directly into
the THAT-2. Then, using the supplied cable,
connect the THAT-2 back to the telephone.
Now connect your audio equipment to the RCA
or XLR jacks. The gray pushbutton selects
which audio will be sent into the telephone
(OUT = talking on the handset, IN = sending
audio in through the RCA or XLR jacks). The
output jacks contain a nice mix of audio from
both sides of the conversation as well as the
tones being pressed on the telephone keypad. The THAT-2 has a three-position switch
which accommodates electret, dynamic, and
carbon telephone handset microphone types.
The THAT-2 will emulate the type of microphone
that is in the handset and allow you send audio
into many different types of analog and digital
PBX sets, as well as ISDN telephones. The
THAT-2 does not work with cellular telephones
or any telephone with a keypad in the handset.

Four IFB
Four IFB
Multi-Line Phone Bridge
Four IFB is a four position analog telephone line interface
designed specifically to provide flexible listen only IFB* for
television field production use. Each IFB output, and the monitor input / output jacks, may be separately connected to
one of the four analog phone lines through the use of rotary line selector switches. A telephone handset may also be
connected for communication with the Monitor phone line.
Four IFB is designed to be used in a variety of environments and weather conditions. All controls and components
are dust and moisture resistant. A non-removable hinged cover
protects the unit’s selector switches, add/drop buttons and
keypad while the enclosure design protects the volume controls
from physical damage.
*IFB is a broadcast industry acronym which stands for Interruptible Fold Back.
The IFB signal is typically a Program Line (PL) signal from the studio console.
