THE ALL NEW GUEST MODULE™ GM2X6 TALK SHOW CONTROL SURFACE

JK Audio

LET’S TALK...

The single most important function of a talk
show system is getting excellent caller au­dio on the air. While there are many ways to
reach that goal, it is important to look at all
of the attributes of a talk show system, mak­ing sure that everyone at the station has the
ability to get that caller on the air. From
selection and purchase, to installation and
training, every step can be made easier with the
right equipment.

The core of our system is the innkeeper series
digital hybrid. The innkeeper series started over
12 years ago with the introduction of our model

innkeeper 1. The INN1 was our first digital hy­brid to use our Dual-Convergence echo cancel­ler algorithm. This proprietary algorithm allows
near perfect removal of the transmit signal from
the caller audio output, without the need to blast
a noise burst down the phone line. This is accom­plished without the use of Non-Linear Processing
(NLP) compromises such as half duplex or speak­erphone type gating, resulting in a very clean,
natural conversation.

In 2005 we added our innkeeper 2 and
innkeeper 4 Digital Hybrids which remain
the most feature packed hybrids on the

market. Boasting a 600 MIPS DSP for deep echo
cancellation, these extremely flexible units
have become a staple in TV studios and
SAT/ENG trucks for behind the scenes IFB
communications. INN2 features a conf­erence mode with several caller output op­tions, making it a breeze to connect to your
console. Recent firmware updates provide
enhanced audio quality while adding
RS-232 control capability.

In 2007 we set the bar a little higher on our
innkeeper 1x by upgrading to a 600 MIPS DSP.
This added horsepower allows extra deep echo
cancellation and improved signal processing,
while adding an RS-232 port for remote call
control.

With the latest firmware enhancements,
innkeeper models 1x/1rx, 2, and 4 sport
significant improvements in audio quality.
Audio enhancements that move beyond simple

objective lab measurements of performance,
utilizing advanced psycho-acoustic based signal
processing techniques. Dramatic improvements
using techniques that take into account the
physiological and psychological models of
human hearing to achieve performance that
goes beyond mere dB separation measurements.
There are areas of the spectrum where our
ears are more sensitive to non-linearities. Extra
processing resources are focused on these areas

to ensure natural sound from every caller.

Are your analog phone lines going away, or
already gone? No problem. Innkeeper digital
hybrids are globally compliant and compatible
with most PBX and VOIP analog line ports.
We come to the talk-show table with a base of
thousands of hybrids installed around the world.

CLEAN CALLER AUDIO FROM ANY PHONE LINE, AND HIGH SPEED SERIAL REMOTE CONTROL.
WHAT WERE WE PLANNING?

ENTER THE NEW CONCIERGE™ 2X6 SWITCH CORE

Concierge allows connection of two hybrids
across six phone lines. The switch matrix routes
six incoming analog phone lines to JK Audio inn­keeper 1rx™ or innkeeper 2™ Digital Hybrids. A
firmware upgrade is all that is required
to make most older model INN1x/
INN1rx and INN2 hybrids compatible with this
new system.

Concierge adds music on hold input, auxiliary
phone integration, and intuitive call control.
Two Concierge switch cores can be bridged
together, providing six additional phones lines
for a 2 hybrid, 12 line system. Front panel
DIP switches, hidden behind an access door,
allow programming features such as the
number of rings for Auto-Answer, and enabling
Auto-Drop feature.
