Learning to Listen
Our motto has always been to listen closely to customer requests and distill the
information down into new product ideas. I recently had a humbling experience.
For years customers have been asking us to build a simple auto-answer coupler.
Frankly I didn’t see the need, since there were already several on the market.
But the customer requests began to build. Finally we decided to cave in to their
demands. We figured if we were going to do it, we’d better make it special or not
do it at all. Eight months later AutoHybrid became our fastest selling product ever.
Our customers were looking for a simple hybrid built the way we build all of our
products. Listen to the customer, don’t cut corners, and they will be happy.
This year we introduce PBXport; a rack mount, road tough, and studio worthy version of our popular
innkeeper PBX. While innkeeper PBX has created its own following as a personal desktop interview
tool, we’ve been asked by many to build a rack mount version with features specific to their applications. Building on the success of innkeeper PBX, we anticipate very good response to this latest
release.
Ever since we introduced Innkeeper 1 we’ve been asked to build a two channel digital hybrid. Again,
there were already several on the market and we really didn’t think another typical two channel unit
would make an impact. Now, a two channel digital hybrid with a keypad, phone book, and conference
feature; that would have an impact! Check out Innkeeper 2 on page 10.
Please keep the suggestions coming. We promise to listen.
Thanks,
Joe Klinger

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.

Digital Hybrid
innkeeper 1
innkeeper 1r
innkeeper 1 and 1x
The Innkeeper 1 gets audio in and out of analog
telephone lines. It’s excellent caller audio does
not exhibit the transmit/receive crosstalk common to analog hybrids, making it perfect for
radio or television talk shows, teleconferencing,
or auto-answer IFB feeds.
Innkeeper 1 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, so 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 excellent trans-hybrid loss, typically exceeding 50 dB, without any setup.
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, all of the remote features can be
found on real screw terminals for ease of installation. And, of course, the audio connections:
mic/line switchable XLR input, XLR caller output and an additional, user-defined XLR output.
Now 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. And possibly the coolest feature:
The innkeeper 1 can be controlled by the Guest
Module 1, the optional remote control keypad.
The Innkeeper 1r is the 19" rackmount version of the innkeeper 1. You will find the same
features as the desktop version with a physical
layout that makes a lot of sense. From the
front panel you can control on-hook/off-hook,
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”. Auto-Answer and
Presence switches are also hidden behind the
access panel. The mic/line switch is located on
the back of the unit, along with all audio and
phone line connections.
Remote Keypad
Guest Module 1
Guest Module 1 gives you remote access to
the on-hook/ off-hook and dial features of the
Broadcast Host and innkeeper 1 series digital
hybrids. This little time-saver gives you call
control you simply can’t get with an auxiliary
telephone and a couple of switches. Connect
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.

innkeeper 1x
innkeeper 1rx
Innkeeper 1x and 1rx contain all of the features
found in the innkeeper 1, plus three additional
features. 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 hosts voice. 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. 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.

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 extensionphone 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.

Multi-Line Digital Hybrid
innkeeper 2
innkeeper 2 and 4
Innkeeper 2 and innkeeper 4 squeeze two
or four independent digital hybrids (respectively) into a 1U rack space. The front panel
keypad, display, and handset jacks provide
easy speed dialing and call setup. Digital
hybrids allow you to send signals into the
phone line while maintaining excellent separation between your voice and the caller. The
balanced XLR output jacks contain only the
caller’s voice.
Digital hybrids connect audio signals to standard analog telephone lines 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.

The menu driven keypad and back lit display
allow 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. An auxiliary telephone jack is provided for each line.
The auxiliary telephone is disconnected when
you press the “Call” button, and reconnected
when you press the “Drop” button.
Innkeeper 2 and 4 feature Auto-Answer/
Auto Disconnect for use in IFB and monitoring applications. Other applications include:

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.
Menu System
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 momentary
switch which toggles the line on or off hook.
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).

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 inkeeper 1 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 end 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.

ring voltage or talk battery which may be
required by modems or other manufacturers

and handset for quick access to audio in and
out of the telephone. The THAT-1 is used by radio
stations to record and play sound bites, and
by computer and telephone companies to
demonstrate their computer voice services
using a powered speaker.
Simply plug the THAT-1
between the handset and
the base of your phone

Simply unplug the handset coily cord from the
base of your telephone and plug it directly into
the THAT-1. Then, using the supplied cable,
connect the THAT-1 back to the telephone.
Now connect your audio equipment or powered speaker using the RCA jacks. The grey
pushbutton selects which audio will be sent
into the telephone (OUT = talking on the
handset, IN = sending audio in through the
RCA jack). The output RCA jack contains
a nice mix of the audio from both sides of
the conversation, as well as the tones being
pressed on the keypad. The volume control
adjusts the volume of the signal going to your
powered speaker or tape recorder.
The THAT-1 will work with many different
types of analog and digital PBX and ISDN
telephones. The receive side of the THAT-1
(audio From Phone), will work on any telephone. To send audio into the telephone (To
Phone), the telephone must have an electret type microphone in the handset. If your
telephone has a round mouthpiece or if you
intend to use this product on many different
telephones, you should consider our model
THAT-2, which is compatible with more telephone systems. The THAT-1 does not work
with cellular telephones or any telephone with
a keypad in the handset.

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 threeposition 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.
Simply plug the THAT-2 between the
handset and the base of your phone

Telephone Handset IFB Tap
QuickTap IFB
Connect the QuickTap IFB between your telephone and handset for quick access to audio
from any telephone system.
Simply unplug the handset coily cord from the
base of your telephone and plug it directly into
the QuickTap IFB, then, using the supplied
cable, connect the QuickTap IFB to the base
of the telephone. The 600 ohm male XLR lets
you take audio from the phone line and route it
into a mixer or headset amplifier. You can also
plug an IFB earpiece directly into the 1/8” mini
jack. But keep in mind this is a passive box with
a 600 ohm output; the earpiece should have
an impedance greater that 600 ohms to get
usable output.
Both audio output jacks contain a nice mix
of the audio coming from the phone line and
the handset audio going into the phone. Any
conversation over the handset is sent over
both audio output jacks. Or you can leave the
handset disconnected and just hear audio from
the far end of the call. QuickTap IFB does not
work with cellular telephones or any telephone
with a keypad in the handset.

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

and the audio signal. When the computer audio
card is connected to your studio equipment, the
electrical noise from the computer can leak into
the rest of your audio system.
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
The Pureformer completely isolates the electrical ground of the two systems and only allows
audio signals to pass through. Pureformer cannot remove noise once it has been mixed with
the audio signal, so it is important to find and
treat the source of each problem.

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
Specifications
Internet Telephone?
You can also use the TAP-1 to power a cordless telephone and connect the audio paths to
a sound card for use as an internet telephone.
Imagine roaming the house as you talk over the
internet.
Line Input: RCA 600 ohms, 250 mV RMS
(–10 dBm nom)
Bandwidth: 60 Hz–15 kHz (± 3 dB),
120 Hz–8 kHz (± 1 dB)
Line Output: RCA 600 ohms, 250 mV RMS
(–10 dBm nom)
Bandwidth: 180 Hz–12 kHz (± 3 dB),
300 Hz–6 kHz (± 1 dB)
Phone Line AC Impedance: 510 ohms
DC series resistance: 480 ohms
DC Voltage: –48 VDC (open circuit)
DC Current Max: 70 mAn (short circuit)
Trans-Hybrid Loss: >50 dB at 1 kHz
Power: 18 VAC, 160 mA (120 VAC,
UL approved transformer supplied)
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.
