Overview 1
Introducing the Concierge™ 2x6
The Concierge™ 2x6 switch core allows connection of two hybrids across six
phone lines. The switch matrix routes six incoming analog phone lines to either
one or two JK Audio innkeeper 1rx™ single channel Digital Hybrids, or one
innkeeper 2™ Digital Hybrid. A rmware upgrade is all that is required to make
most older model INN 1x/INN 1rx and INN 2 hybrids compatible with this new
system. See page 11 for innkeeper compatibility.
Concierge adds music on hold input, auxiliary phone integration, and intuitive
call control. The end result is a powerful, exible system featuring excellent call
screening capabilities, while allowing two studios to share the phone lines.
Two Concierge switch cores can be bridged together, providing six additional
phones lines for a 2 hybrid, 12 line system.
Up to eight Guest Module control surfaces can be added to provide remote
control of the switch matrix over CAT5 cable. Guest Modules are hot swappable
without losing calls, and feature line selection buttons that change color to
indicate call status. Guest Modules are available in GM1x6, GM2x6, and GM1x12
desktop and rack mount versions.
The smallest system consists of one Concierge switch core, one innkeeper 1rx,
and one Guest Module GM1x6 control surface.

Line LEDs
Each phone line port features dedicated ring detect, line current detect, polarity
reversal detect, line presence, and hold circuit. Front panel LEDs indicate various
line states. A green Line LED indicates the line is o󰀨-hook and properly wired,
while a red Line LED indicates the line is o󰀨-hook but reverse wired. In most
cases, reverse wiring will not a󰀨ect system operation. The only exception is
during innkeeper 1x/1rx conferencing, where both lines are electrically bridged
together. Two lines of di󰀨erent polarity cannot be joined in a conference. It is
advised to go through each line to ensure a properly wired connection.
The Concierge front panel Line LEDs indicate when a phone line is taken o󰀨-
hook through the Concierge system. These LEDs do not indicate when a phone
line is already o󰀨-hook outside the system, or if the line is disconnected or out of
service.

Installation Options
Installation Options
The Concierge system is very exible, o󰀨ering many conguration options. The
number and type of hybrids and Guest Module control surfaces help determine
the system capabilities. It is best to look at your requirements rst, then choose
the right hybrids and controllers suitable for your unique installation.
The rst decision is whether you intend to conference two callers together,
putting both calls on the air simultaneously. This can be accomplished with a low
cost innkeeper 1x/1rx by allowing the system to combine two calls together into
one audio input on your console. Keep in mind that you will not be able to adjust
the level of the caller’s voices independently if one caller should prove quieter
than the other. Innkeeper 2 uses two separate digital hybrids to bring caller audio
into separate inputs on your console, while providing the necessary cross-
connections so everybody can hear each other.
If conferencing is not in your game plan, you may wish to keep it simple using
GM1x6 controllers. GM1x6 o󰀨ers all the features of the GM2x6 without the
possible confusion of monitoring the second half of the 2x6 switch core, which
may not be a part of your installation.
Whether conferencing is in you plans or not, you might want to consider a mix of
GM1x6 and GM2x6 control surfaces depending on the location. A news studio
or call screener may not need conferencing, and may be better served by the
simpler GM1x6 control surface.
The following examples show the capabilities of each hybrid:
One innkeeper 1x/1rx™ Hybrid: pg 5
Two innkeeper 1x/1rx™ Hybrids: pg 6
One innkeeper 2™ Hybrid: pg 7

Installation Options 5
One innkeeper 1x/1rx™ Hybrid
The smallest system consists of a one line hybrid and at least one GM1x6 or
GM2x6 control surface. This is the most common system assembled when there
is only one studio and one optional screener position.
One innkeeper connects to the Hybrid 1/A jacks on the Concierge, as does at
least one Guest Module. Any GM1x6 or GM2x6 controllers connected to bus
1/A will display calls on row A of the Guest Module. A second GM1x6 or GM2x6
control surface can be connected to Guest Module control bus 2/B along with an
Auxiliary phone connected to Aux Phone Port 2/B to provide an independent call
screening position. Any GM2x6 controllers connected to bus 2/B will display calls
routed to the Aux phone on row B of the Guest Module. A GM1x6 connected to
bus 2/B will display these same calls shifted up to its top row.

Two innkeeper 1x/1rx™ Hybrids
This is a typical conguration if two studios share the same six phone lines. With
two single line hybrids, one will get connected to port 1/A and one to port 2/B.
Any GM1x6 or GM2x6 controllers connected to bus 1/A will display calls on row
A of the Guest Module. Any GM2x6 controllers connected to bus 2/B will display
calls on row B of the Guest Module. A GM1x6 connected to bus 2/B will display
these same calls shifted up to its top row.
Two separate single line hybrids allow one two-caller conference on rowAwith
one audio output, and a separate two-caller conference on row B with a separate
audio output. These conferences cannot be combined.Any lines routed to hybrid
1 cannot be accessed by hybrid 2, and vice versa.

Installation Options
One innkeeper 2™ Hybrid
While one innkeeper 2 hybrid can function as two separate hybrids as in
the previous scenario, conferencing was designed primarily for a one studio
application. The innkeeper 2 hybrid connects to the 1/Ahybrid port. The
innkeeper 2 brings row A and row B callers into the console on separate audio
channels, allowing independent level control even during conferencing.
Bus A can be used for the studio Guest Modules. Bus B can be used for a call
screener, allowing the screener access to the second hybrid channel or second
aux phone port for call screening while the studio airs calls on Bus A.
Keep in mind that when Conference is selected, both Bus A and Bus B are
joined together in a conference, and the screener no longer has the ability to
screen calls.
One innkeeper 2™ Hybrid with Two Concierge Switches
This system can be expanded to 12 lines by simply adding a second Concierge™

Step 1: Phone Line Wiring
Connect each phone line directly to the RJ-11 jacks on the back of the
Concierge. Auxiliary phones should be connected to the 1/A or 2/B Phone Ports
for proper system integration. Do not use external line splitters to connect an Aux
phone. Do not connect an Aux phone to the innkeeper digital hybrid.
Step 2: Hybrid Connection
Two cables join each hybrid to the Concierge Switch Core.An RJ11 Modular
phone cord connects the innkeeper Phone Line jack to the Concierge 1/A or 2/B
Hybrid Phone Port. The remote data cable connects the innkeeper remote jack to
the Concierge Hybrid Remote jack.
Step 3: Guest Module Control Surfaces
A maximum of four guest modules can be connected to each of the two
Guest Module ports, for a system maximum of eight Guest Modules. The dual
connection ports on each Guest Module allow for quick daisy-chain wiring, or
you may simply run all cables back to a terminal block to allow for point-to-point
wiring. The maximum distance from Concierge to the farthest Guest Module is a
function of the number of Guest Modules connected, as well as the the gauge of
the wire chosen. Standard 26 gauge cable can be used on runs shorter than 100
feet, but as distance and the number of units increase, you may need to consider
24 gauge CAT5 wire.
While Guest Modules use standard CAT5 cable, the communications protocol
is balanced di󰀨erential RS-485 using a custom pinout. This is not an Ethernet
connection, and should not be connected to a data hub or switch.
2x12 Expansion
Two Concierge switch cores can be bridged together into a 2x12 system,
providing six additional phone lines. Begin with both Concierge Switch Cores
powered down. On the second Concierge, DIP switch 5 must be set to the ON
position, shifting line assignment to lines 7-12. Now connect the phone and data
expansion bus cables from the rst unit to the second unit. Upon power-up, both
units will display a green “Bridge” LED indicating that they are now properly
communicating. Only GM1x12 control surfaces can be connected to a bridged
system. The GM1x12 control surfaces can be connected to either the 1/Aor 2/B
control bus on the Master (1-6) Concierge Switch Core. All hybrid and Guest
Modules connections are made through the Master Concierge unit. Only the
Phone Line and Expansion Bus jacks are used on the Slave Concierge unit.

Dip Switches
The Concierge™ 2x6 Switch Core is equipped with 12 slide style DIP switches
located underneath the removeable cover plate on the front. Congure your
Concierge by enabling or disabling features by switching between the ON and
OFF positions for each DIP switch. The following chart shows each feature and
it’s corresponding switch.
Auto-Drop
OFF (Default):Places the current call on Hold when either a Line button,
Next, or Previous button is pressed.
ON: Will drop the current call when either a Line button, Next or Previous
button is pressed, unless the call is manually placed on Hold.
Slave
For 12-line systems:
OFF (Default): In the ‘O󰀨’ position, the Concierge behaves as the master
device, controlling the rst 6 lines.
ON:When bridging two Concierge Switch Cores, use the Expansion bus
to create a 12-Line system. Flip the Slave DIP switch to the ‘On’ position
to convert Lines 1-6 to Lines 7-12 on the second Concierge Switch Core.

Conguration

Auto-Drop
Most PBX phone systems (and talk shows systems for that matter) are built
on the premise that when you are done talking to one person, and you select
a di󰀨erent line, the rst caller automatically gets disconnected. In other words,
you have to go through an extra step to place a call on hold. While this has the
distinct advantage of allowing you to get through calls quickly, you are also more
likely to accidentally lose a call. With Concierge, you have a choice:
• When Auto-Drop is ON, calls are automatically dropped after selecting a
di󰀨erent line, or using the Next and Previous buttons, unless you specically
put a call on hold.
• When Auto-Drop is OFF, calls are automatically put on hold after selecting a
di󰀨erent line, or using the Next and Previous buttons.
ATTENTION: Auto-Drop is OFF by default, it can be Enabled/Disabled by
using the DIP switch panel (see page 9).
Aux Phone Control
The use of a conventional telephone for call screening and dialing can be an
important part of any system. Concierge Aux Phone jacks provide seamless call
control, allowing the phone to become an integral part of the system.
The Aux Phone takes precedence over the hybrid, similar to picking up the
handset during a speakerphone call. Picking up the handset of a phone
connected to an Aux Phone jack during a call, will disconnect the Hybrid and
connect the Aux phone to the phone line. This is true in all cases except when
using an INN2 in Conference mode, when nothing will happen until one of the
two phone lines is selected.
The Aux Phone will follow these basic rules:
• If a phone connected to the Aux jack is o󰀨-hook before a line select button is
pressed, the line will be connected to the phone instead of the hybrid.
• If a call is routed to the hybrid and the phone is taken o󰀨-hook, the phone will
take control of the call.
• If the Aux Phone is not present, or on-hook, pressing a line select button will
connect that line to the hybrid.
• If the Aux Phone is connected to a port where no hybrid is connected, and the
phone is on-hook, pressing a line button does nothing.
• If auxiliary phones are part of your system, they should be connected to the
1/A or 2/B Phone Ports for proper system integration. Do not use external line
splitters to connect an Aux phone to any other port. Do not connect an Aux
phone directly to the innkeeper digital hybrid.

Phone Line Compatibility
Concierge works with standard POTS (Plain Old Telephone Service), PSTN
(Public Switched Telephone Network) phone lines. The phone line ports have
been tested and approved for most international POTS/PSTN line conditions, ring
patterns, voltages and frequencies, as well as call disconnect signaling. Concierge
also works on most analog line ports from PBX or VoIP phone systems, however
these systems are not required to adhere to the specications of the POTS/PSTN
network. PBX/VoIP analog line ports may need additional settings adjustments
through your system administrator or installer.
