1Overview
LQ™ allows you to connect 4-wire and partyline audio with call signaling over IP
networks quickly and easily.
The product line provides a unique combination of low latency with exceptional
audio quality and an intuitive, easy to use design.
The LQ product is available in 5 models; the LQ-2W2 and LQ-4W2 devices are
small, robust 2-port throw-down boxes for fast and convenient installation. These
devices operate on Power over Ethernet (PoE) for situations where a power supply
is not easily available. The LQ-R devices (LQ-R4W8, LQ-R2W4-4W4, LQR-2W4) are
single rack units providing 4 or 8 ports in a combination of 4-wire and 2-wire
options for more extensive installations.
The LQ product line offers:
•LAN, WAN and Internet connectivity
•Up to 48 ports of audio can be routed through the system using
customizable Virtual Partylines
•Up to six units can be linked together
•5 different LQ models.
•Web based Core Configuration Manager (CCM)
•Per-port adjustment of network/audio quality settings
•Low latency OPUS CODEC
•LQ units: External power supply or Power over Ethernet (PoE)
•LQ-R units: Dual redundant external power supply
•2-wire
o2-wire line termination,
oAuto nulling,
oClear-Com/RTS modes with both RMK/Call signaling pass-through
•4-wire
o4-wire To Panel/To Matrix interface switch
oPanel data can be transmitted, allowing panels to connect over LAN,
WAN and Internet.

2Basic setup (LAN)
2.1 Setting up your LQ environment
Prepare your environment by gathering the following equipment:
•LQ units (LQ #1 and LQ #2)
•(2) provided power supply units (PSUs)
•(2) Straight-through Ethernet cables
•(1) Network connection with dynamic host control protocol (DHCP) server
present
•(2) 2-wire or 4-wire devices to provide an audio connection to each LQ
1) Using the Ethernet cable, connect LQ #1 to LQ #2 using either using either
LAN port on the rear of the unit.
2) Using another Ethernet cable, connect LQ #1 to your DHCP enabled network.
Figure 2-1 LQ device front panel display (4-Wire)
Note: The IP address will be allocated by DHCP (default mode). In the event
that the network does not serve DHCP or there is no network
connection, the IP address will revert to a link-local address. See 8
Link-local environments for more information.

3) Connect the provided PSU to each LQ device. Each device will display an IP
address on the front panel display.
4) Connect audio equipment to Port Aof each LQ device.
Figure 2-2 Basic setup
2.2 Accessing the Core Configuration Manager (CCM)
From a computer, open a Web browser. Enter the IP Address as displayed on the
LQ #2 device in the address field of the Web browser (Chrome, Safari, Firefox, IE,
Opera). This takes you to the Core Configuration Manager.
Note: Default username and password for the CCM: admin, admin.

2.3 Create a Link-Group
Before linking units together, one LQ device must first be designated as the Link-
Master. This is accomplished by setting that device's role to Link-Master. Every
other LQ device within the Link-Group will then be set into a Link-Member role
which allows the linking of those units directly to the Link-Master.
In this example, LQ #1 will be left as Link-Master (default configuration) and LQ
#2 will be linked to it.
1) Navigate to Home > Linking on the CCM of LQ #2.
2) Click Change Role to Link-Member.

16
399G116 Rev D
3) Within the Master IP address field, enter the IP address as displayed on the
LQ #1 device. Click on blue check mark or <ENTER> key to submit.

17
399G116 Rev D
4) Select an available device ID (highlighted in blue).
5) Click Apply changes.
LQ #1 and LQ #2 will now be linked.
6) Navigate to the Overview page (top navigation bar). Both LQ devices should
be displayed on this page.
7) Before continuing, if either LQ device is a LQ-2W2 model, auto-null both
ports. For each device: within the General page, navigate to A/B.
8) Expand port sections (A and B) and click on the Auto-Nulling button for each
port.

2.4 Assigning ports to a channel
1) Click on the Assignments button within the navigation bar.
2) Select the Channel tab.
3) Add Port A on each device to Channel 1 by clicking on the +symbol to the
right of each port.
You should now be able to pass audio and call/RMK signaling to/from Port A
on each device.
Note: Channel 1 must be selected before audio can be assigned to it. This is
shown by an orange highlight.

3Powering your LQ™
Figure 3-1 LQ unit rear panel (2-wire device)
3.1 Using the power supply unit (PSU)
•LQ units are supplied with a 24 watt sleeve-locking power connector.
•LQ-R 1RU units are supplied with two 60 watt sleeve-locking power
connectors. Use either power connector, or both to guard against one
power supply failing.
Note: When connecting the sleeve-locking power cable, be sure to push until the
connector locks into the device.
3.1.1 Understanding power display icons
You will be able to see the power status of your device is from:
•The front panel of the unit
•The device icon in the web based configuration tool (the CCM).
These indicators will show if the unit is using PoE or the PSU (LQ throw-down
units), and which of the two power supplies (or both) are in use for the LQ-R units.
