Understanding power display icons
You will be able to see the power status of your device from:
l The front panel of the unit
l 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.
LQ throw-down units
If the device is using the PSU, this will be
lit up instead of the PoE indicator.
LQ-R 1 RU units
2.2 Using Power over Ethernet (PoE) with 2-port units
The 2-port units will receive power from the LAN1/PoE connector if required (this is
not the case for the larger LQ-R units).
When using PoE the LQ-2W2 supplies approximately 70 mA of power to drive the
wired beltpacks (about two beltpacks).
The units draw up to 12 watts of power (depending on what is connected to them),
so when using PoE you should have at least a Class 3 PoE switch.
If you exceed the power of your switch or network, the LQ device(s) will show a
persistent flashing green light, and not move beyond the Clear-Com splash screen.

This indicates that the device is continually booting and needs more power.
Consider using the supplied sleeve-locking connector cable or a higher Class PoE
switch.
2.3 Power 2-wire beltpacks from the Partyline
2-wire beltpacks take power from the Partyline. The maximum numbers are shown
in the table below.
2.4 Reboot system
The system will start its boot sequence immediately when power is applied. If you
need to reboot for any reason, either cycle the power or press all four direction keys
on the control panel on the front of the LQ unit at the same time.
The system can also be rebooted using the front panel menu screens: Menu >
Administration > Reboot and from the CCM: Device > General >
Maintenance > Reboot.

3 Core Configuration Manager (CCM) walkthrough
This section gives you an overview of your configuration tool. Find context sensitive
help in the user interface by clicking on the blue ? icon.
3.1 How to Access the Core Configuration Manager (CCM)
1. Make sure the LQ device is connected to a network (either LAN connector on
back of device).
2. Open a browser (PC, tablet, mobile) on the same network as the LQdevice and
input the IP address of your LQ in the addressfield. Find the IP address in the
front menu screens of your device.
3.1.1 Minimum requirements for the CCM
Supported on the latest versions of all major web browsers (i.e. Google Chrome,
Safari, Firefox, Internet Explorer, Opera).
3.2 Overview
This page shows an overview of all the devices in your system. Devices in the upper
part of the page are the units in a Link-Group. As LQs are added to the group, they
appear in this screen. A HelixNet device can also be included in a Link-Group (LQ
4.0 and above).
On the lower part of the screen you can see the external systems that your LQ
device is connected to. These can be:
l IVC (matrix) connections
l SIP (telephony interface) connections
l Agent-IC (mobile client) connections.
If you have a HelixNet in your Link-Group, you will see the remote units that are
connected to the HelixNet Main Station in the lower half of the Overview screen.

3.2.1 Device Configuration
Devices in a Link-Group can be configured either directly or by proxy, meaning that
the configuration operations for a unit are routed through the host device. The host
device is the unit which the browser is currently pointed to (orange highlight).
Click on the gear icon on any device.
You can use the Overview page to obtain diagnostic information for your all
systems. Whenever you see a > symbol, click to see a drop-down section.
Clicking the gear icon in any part of the CCM always takes you to programing
options.
3.2.2 Resource Bar
User Guide| LQ Series 4.0
3.2.3
Page 24
About the Resource Bar
The Resource Bar is a tool that indicates the amount of processor power currently
allocated on that device.
l Bar orange = 70% of processing power reached
l Bar red = 80% of processing power reached
The device will work in the red zone, but the reliability of the audio response may
decrease.
Page 25
User Guide| LQ Series 4.0
The CCM will start limiting demands on the unit (for example it will prevent a port
being added to a Channel, or the addition of an IVC-32 or multi-Channel port) in
order to maintain good audio quality and responsiveness.
3.2.4
To optimize resource usage
l Reduce the network quality in the local audio mixes. Higher network quality
takes more resource.
l Reduce the number of ports that are in different Channels. Several ports in the
same Channel do not take much resource. It is more demanding if the ports
are spread over several Channels.
l Using a LAN/WAN/Routed Network Optimization mode will reduce the
overall resource usage (set Link-Group Optimization mode in the Linking
page of the CCM).
3.3 Device
The Device page takes you to the configuration options local to your LQ device. On
the left you see configuration page buttons; General, Network, Linking and

Maintenance
Reset the unit to default settings.
Reboot the system.
Create a support archive. Support Info provides a 'snapshot' of the device's
operational information for troubleshooting purposes.
3.4 Network
Dynamic host control protocol (DHCP) or Static IP address allocation?
Default setting: DHCP
It is recommended that the Link-Master in a Link-Group has a static IP
address.
Most networks use DHCP to allocate IP addresses. Because of this, DHCP is
recommended for fast set-up as the devices can be immediately connected to any
network that provides DHCP. The addresses provided are dynamic and may change
from time to time. Because DHCP IP addresses can change, the Link-Master should
have a static IP address, or it may lose connectivity to the group.
For more information, see:
Network settings (IP) on page 74
Internet connectivity on page 78
Link-local environments on page 76
External IP address and External Port setting
For efficient networking, these details should be set for any LQ device that connects
over a firewall.
Note: The Link-Master uses TCP port 80 for management, and TCP/UDP port 655 for
audio. See Linking over Internet or WAN below for port addressing and port
forwarding details.

3.6.6 Multi-Channel Ports
It is possible to assign one port to many Channels. There is no limit on the amount
of Channels a port can be put into, but the rules for device resource usage apply.
When the unit is reaching the limits of its capacity, the user interface will stop you
from assigning more ports.
When do I use multi-Channel ports?
An example of when to use multi-Channel ports might be if you have a program
feed or stage announce that should be heard by several teams or groups.

Enable multi-Channel port feature
Once enabled, multi-Channel ports are available in the Assignments page, ready to
be assigned to more than one Channel.
Note: If the port has already been put into a Channel, it will be unassigned from the
Channel when you enable multi-Channel support.

Page 39
User Guide| LQ Series 4.0
For more information on how to put ports in Channels see Assignments on page

Note: Multi-Channel ports will not be placed in a local audio mix, they will be transported
as a single audio stream. You can use the Resource Meter as a guideline for device
capacity.
For more information, see:
Resource Bar on page 24
3.7 Roles
When using LQ, some of the products you interconnect with use Roles for the
purpose of intercom setup. Roles are preset configurations, used to simplify and
control your intercom installation. You can work with default Roles which can be
cloned or edited. You can also create your own Roles if required.
The products that use Roles when connecting to LQ devices are: HelixNet and
Agent-IC.
When a HelixNet device is linked to LQ in a Link-Group set up, the Role
configuration from the Master HelixNet device will override the LQ units.
For more information about HelixNet Role configuration, see the HelixNet User
Guide, available from the Clear-Com website.
For more information about Agent-IC Role configuration see Agent-IC and LQ on

Note: Direct Channels are not available in a HelixNet system.
3.8.2
Channel or 4W Direct Channel?
An LQ Channel is made up of multiple audio sources which operate as a partyline.
All sources in a Channel can hear and talk to each other. A 4-wire direct (panel)
Channel, by contrast, is a connection between two ports only. A 4-wire direct
(panel) connection cannot be included in a Channel and is configured separately.
Local Audio Mix (LAM)
Each LQ device within a Channel performs its own local audio mix (submix). The
LAM mixes audio at a very early stage of the audio transport which reduces the
latency of the audio streams (below 4ms) and improves audio processing. LAM is a
Page 41
Page 42
User Guide| LQ Series 4.0
way of improving latency, increasing the capacity of an LQ device in certain user
cases and reducing network usage.
The LAM is performed automatically when ports are added to a Channel.
Note: The ports from each LQ appear within a box, with the local audio mix icon in the
bottom right corner, where you can program network settings.
Network settings within a Channel are set on a per-device basis. To set differing
network quality for ports from the same device, put the ports in separate Channels.
Note: LAM is not available if you are using a HelixNet/LQ Link-Group.

Custom setting
The Custom option allows adjustment of the jitter buffer setting independent of bit
rate and packet size.
The jitter buffer setting is designed to buffer audio received to prevent loss if there
is network jitter. Note that the jitter buffer selection will directly affect the latency.
This is because the lower number in the jitter range represents the amount the LQ
unit will buffer audio before delivering it to the port. A bigger jitter buffer setting will
increase latency in milliseconds.
Note: The network setting is the bandwidth from the LQ device into the IP network.
Note: Within the Custom setting, selecting an Audio Bitrate of 128 Kbps will automatically
set Bandwidth to 20 kHz,

4.2 Creating a Link-Group
Before linking units together, one LQ device must first be designated as the LinkMaster 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.
When creating a HelixNet/LQ Link-Group the HelixNet must always be designated
the Link-Master.
Page 48
Page 49
User Guide| LQ Series 4.0
In this example, LQ #1 will be left as Link-Master (default configuration) and LQ #2
will be linked to it.
4.2.1
How to create a Link-Group
1. Navigate to Device > Linking on the CCM of LQ #2.
2. Click Change Role to Link-Member.

6 Linking
6.1 What is a Link-Group?
A Link-Group is a set of LQ devices connected over IP so they share audio and data
between them.
With LQ 4.0 and above a HelixNet device can also be included in a Link-Group. This
increases the available ports and the range of a HelixNet system.
User Guide| LQ Series 4.0
Page 57
Page 58
User Guide| LQ Series 4.0
The Core Configuration Manager (CCM) for any LQ host can be accessed by entering
the IP address as displayed on the front panel display of the LQ host into a web
browser's address field. All devices in the Link-Group can be viewed and configured
through any single host in the Link-Group.
Note: A HelixNet Main Station can also be linked in a Link-Group formation. The basic
principles are the same for a HelixNet/LQ Link-Group, though there are a few
differences in operation.
For more information, see:
LQ to HelixNet connectivity on page 123
6.2 About Linking
A Link-Group:
l Can contain up to 6 LQ devices or up to 6 of a combination of HelixNet Main
Stations and LQ devices
l Must have one unit designated as Link-Master
Page 58
l Performs a “best effort” approach to creating a mesh network between all the
devices within the group.
Page 59
User Guide| LQ Series 4.0
6.3
Note: The Link-Master must be reachable on TCP port 80 and TCP/UDP port 655 by all
Note: It is recommended that the IP address of the Link-Master is allocated statically.
Note: Any device can be set to Link-Master mode. Link-Master mode is the factory default
The Link-Master role
The Link-Master role serves three main purposes:
1. It facilitates Link-Group membership.
2. It is the owner of Channel names, meaning that Channel names will only persist
(be maintained consistently) if the Link-Master is operational.
3. It is responsible for the synchronization and distribution of both configuration
and device availability status throughout the Link-Group.
devices within the Link-Group.
When allocated by DHCP the IP address can change. If this happens the LQ devices
will no longer be able to reach the Link-Master device.
setting.
Page 59
Page 60
6.4 The Link-Member role
LQ devices that are not designated master will have the role of Link-Member.
Joining a device to a Link-Group requires that device to be set to Link-Member role
which will prompt the user to enter the address of the Link-Master.
If a Link-Member device loses connection to its Link-Master, the front panel LED of
that device will turn red until the connection is restored.
6.4.1 Linking units
The only way to join devices to a Link-Group is through the Linking page of the CCM.
Only the IP address of the Link-Master is required during this set up.
6.4.2 LQ restricted IP range
LQ units use the IP range 172.23.xx.xx for linking. Because of this, this IP range
should not be used for any devices (including LQs) when working with the LQ Series
system. Clear-Com cannot guarantee reliable behavior if this address range is
used.
User Guide| LQ Series 4.0
6.4.3 Linking over a LAN
This is the simplest way to link devices together. This type of environment enables
the highest potential level of communication quality and the best availability of
resources. When linking over a LAN, set Link-Group Optimization to LAN/WAN
routed network in the Linking page of the Core Configuration Manager (CCM) for
best latency performance and use of resources.
6.4.4 Linking over Internet or WAN
When linking over the public Internet, addressing of the Link-Master becomes more
complicated as the Link-Master must be made externally reachable to all LinkMembers. This is achieved by creating port forwarding rules within the firewall.
Note: A HelixNet/LQ Link-Group does not operate over the Internet. This is because the
codec that HelixNet uses (WavPack) is not optimised for the Internet. Internet
connectivity when using HelixNet and LQ is achieved using a tie line.
Page 60
Page 61
6.5 How to link LQ units over a firewall
User Guide| LQ Series 4.0
The Link-Master uses TCP port 80 for management and TCP/UDP port 655 for audio.
You will need to create port-forwarding rules within your firewall to make these
ports externally accessible to the Link-Master device.
When creating a Link-Group over the public internet, Link-Members need to be
given the Link-Master’s externally reachable IP address and the port that is
forwarded to port 80. This information is entered in the Linking page of the CCM.
Note: If no port forwarding rules have been applied the LQ devices will find the correct
default ports automatically, so there is no need to specify a port.
Once the devices are linked in a group, they will share network details with each
other automatically. To facilitate this, the network details, including the port that is
forwarded to TCP/UDP port 655 need to be configured in the Link-Master’s
Network page. If no port forwarding rules have been applied, it is not necessary to
specify a port.

6.6 How to remove a device from a Link-Group
6.6.1
6.6.2
Remove an on-line Link-Member from a group
1. Access the browser-based CCM for any device within the Link-Group.
2. In the Overview page, click on the device image of the unit that you want to
remove from the group.
3. Navigate to Linking for that device.
4. Click Change Role to Link-Master.
5. Apply Changes.
The device will be reconfigured as a Link-Master and removed from the group.
Remove an off-line Link-Member from a group
1. Access the Core Configuration Manager for any device within the Link-Group.
2. In the Overview page, the off-line unit will show a red ‘X’. Click on this device.
3. You will be asked if you want to remove this unreachable device. Click Delete.
The device will be removed from the Link-Group.
If this same device is powered on again, it will automatically seek the same LinkMaster and ID slot. If the ID has been taken by another device, it will take the next
available ID. If no ID is available (because there are already 6 devices in the group)
it will not be able to join the group.
To re-use this device with a new Link-Master, it must be returned to the default role
(Link-Master) and then re-linked.

7 About Channels and using them to route audio
Audio can be assigned to either Channels or 4-wire direct connections.
7.1
About Channels
In the context of the LQ product, a Channel represents a conduit or holder for
routing audio and data (including GPIO triggers) through your intercom system. As
well as routing audio, a Channel also connects audio and data sources.
To use Channels:
l Connect audio to the port connectors on the device
l Assign the port or ports to one or more Channels.
LQ uses two different types of Channel
LQ uses two different types of Channel: a regular Channel and a 4-wire direct
Channel. A regular Channel operates like virtual Partyline or conference line. It
comprises audio from multiple audio interfaces on the devices (ports A-F) that have
been assigned to it. Within a regular Channel, all parties can hear and speak to each
other. A 4-wire direct Channel is made up of only two audio sources in a one-to-one
connection. A 4-wire direct Channel can be used to connect an analogue intercom
panel over IP to an Eclipse matrix. A 4-wire direct is also used to route SIP calls to a
matrix.
Once connected to the units, audio and data from the input/output ports on the
back of the LQ devices can be assigned to any of the 24 available channels. When
an audio route from a port is assigned to a Channel it will be able to talk and listen
to any other ports also assigned to that channel.
Page 64
Page 65
Example of audio channels in a Link-Group.
User Guide| LQ Series 4.0
7.2
Channel or 4-wire direct?
l A Channel operates as a virtual partyline and can contain many audio sources
l A 4-wire direct connection is between two points only
l A 4-wire direct is used when connecting to Eclipse panels
l A 4-wire direct is used when routing SIP calls to a panel
l A 4-wire direct cannot be used with the HelixNet system.
7.3 How many Channels can I use?
LQ series units can provide up to 24 Channels (including 4-wire direct Channels)
across a Link-Group. Use the green ‘Add Channel’ button on the Channel tab in the
Assignments page of the Core Configuration Manager (CCM) to add Channels.
If an LQ unit is linked in a Link-Group setup with HelixNet it will have either 12 or 24
Channels, according to the Channel license of the HelixNet device. Unlike the LQ,
HelixNet has a fixed number of Channels, according to license.

VOX (audio-gating)
The VOX setting has several functions:
l VOX can be used to maximise bandwidth efficiency by detecting when the line
is silent and not transmitting at those times.
l VOX can be used to trigger a Network Control Event (used for sending and
receiving GPIO signals) when audio is detected in the Channel.
l VOX can be used to eliminate unwanted noise, for instance, low level ambient
or background noise.
l VOX mode: Disabled/Fixed Threshold/Adaptive.
If Disabled, VOX is not activated and Network Control Events cannot be configured.
Audio is still detected in the Channel, so audio light will show.
Fixed Threshold: triggers VOX detection (audio gating) according to a fixed level .
Enabling this option automatically enables Threshold and VOX Delay.
Adaptive: sets the audio trigger according to an automatically calculated 'noise
floor'. This option implements comfort noise when silence is detected. Only the Off
Delay option is activated with this setting. The Adaptive threshold is not suitable for
transmitting music.
l VOX Off Delay: 0.5 to 4 seconds. Delays the deactivation of the noise gate to
allow the signal to stabilize.
l VOX Threshold: 0 to -42 dB (default = -22 dB). Set the level at which audio is
considered valid in the Channel.

9 Network settings (IP)
9.1 Dynamic Host Configuration Protocol (DHCP)
The default method for LQ devices to obtain an IP address is DHCP.
Most networks allocate IP addresses using DHCP.
9.2 DHCP or Static IP addressing?
DHCP can be used for quick set-up and the units will work with DHCP IP addressing.
However, the address provided by DHCP are dynamic and can change, so in some
cases it is better to allocate static IP addresses to ensure a completely stable
system.
A static IP address is generally recommended for the Link-Master, while the Link
Members should use DHCP.
If there are additional Port Forwarding rules created in the firewalls that enable
external connectivity to the Link-Members as well as the Link-Master the LinkMember units should also be given static IP addresses.
See Linking over Internet or WAN on page 60
9.3 Static IP configuration
DHCP is not recommended for the Link-Master and is not recommended for units
linked to the master in some situations.
In these cases you will allocate the network settings statically. To do this, navigate
to: Device > Network in the Core Configuration Manager (CCM).
Page 74
Page 75
User Guide| LQ Series 4.0
9.3.1 Netmask or Subnet
The netmask or subnet divides the network into sectors for more efficient routing
and is required when allocating a static IP address to an LQ device.
9.3.2 Gateway
This setting is required when traversing across internets.
For more information, see:

9.4 Link-local environments
User Guide| LQ Series 4.0
9.4.1 What is link-local?
A link-local address is an IP address within the local segment of any network.
Routers do not pass information to these as link-local addresses are not
guaranteed to be unique beyond a single network segment. When first connected to
a network, your LQ device will attempt to get an IP address via Dynamic Host
Configuration Protocol (DHCP). If no DHCP server is available the unit will
automatically enter link-local IP mode. A link-local IP address will take the form:
169.254.xxx.xxx.
9.5 Accessing an LQ unit when in link-local mode
To access the CCM of an LQ unit in link-local, you must connect to it from a PC that
is also in link-local mode.
Devices will revert to link-local mode if they are configured to DHCP and fail to find
a DHCP address on the network or device they are attempting to connect to. A PC
can be put into link-local mode by ensuring it is in DHCP mode and connecting it to
the LQ unit that is in link-local with a standard Ethernet cable. The PC will look for a
dynamically generated IP address (DHCP), and when it does not find one will enter
link-local mode automatically.
Page 76
Once the PC is connected to the LQ and in link-local mode, you can connect to your
LQ unit by opening a browser window on the computer and inputting the unit’s IP
address (from the front panel display) into the address field. This takes you to the
Core Configuration Manager where you can configure the device as usual.
Page 77
User Guide| LQ Series 4.0
Note: The units will operate in link-local, but for optimum performance it is recommended
that they are used with either static or DHCP network settings.

10 Internet connectivity
All devices within a Link-Group must have connectivity to the Link-Master on TCP
port 80 and TCP/UDP port 655. When linking devices over the Internet, make sure
that this connectivity is stable. Internet connection to an LQ device requires special
configuration within your firewall (port-forwarding).
Note: LQ devices cannot connect using the Internet if they have a HelixNet Main Station
as link master.
10.0.1
10.1
Getting an external IP address
When networking LQ devices over the Internet, an external IP address from which
the Link-Master is reachable is required as a first step in making sure Link-Members
can get to the Link-Master. The external (public) IP address must be static and
non-changing. Normally an Internet Service Provider (ISP) will provide external
addressing in Dynamic Host Configuration Protocol (DHCP) mode. This is not
guaranteed to remain static but instead may change periodically. This will cause
linking issues as the Link-Members will not be able to reach the master if the IP
address changes. Therefore, it is suggested that you purchase a static address
from your ISP. Failure to do this could result in a loss of service.
Port-forwarding
To connect to an LQ unit that is behind a firewall, certain ports must be mapped
from your firewall to the LQ device. This mapping will forward traffic received on
those ports from the Internet directly to the LQ unit.
l The Link-Group uses TCP port 80 for linking, data distribution and browser-
based management.
Page 78
l The Link-Group uses port 655 (TCP and UDP) for group connectivity and audio
transmission.

12 What are Networked Control Events and how do I
use them?
12.1
About Networked Control Events
Networked Control Events are used to program input and output triggers (GPI/O) in
your intercom system. They are designed to allow maximum flexibility and
scalability in your use of GPIO events.
For example, Networked Control Events can be used to enable radio communication
over IP, or send a control signal from a panel, via a matrix to a radio. The GPO can
also be used to turn on an 'on-air' light, or perform any other function you require.
A Networked Control Event occurs when the input trigger and the output trigger on
ports in a Channel are set to the same value.
Active Networked Control Events can be viewed in the Assignments page in the
CCM.

Page 83
How to set up Networked Control Events
1. Configure the input trigger on a port. This example shows audio entering a 4wire port (VOX) on an LQ 4W2 device that triggers the output relay on an LQ
GPIO device.
Page 84
User Guide| LQ Series 4.0
2. Configure the output (GPO) on a port.
Page 84
3. Put both ports together in a Channel . This activates a Networked Control Event
when an input and an output Networked Control Event setting match. A GPO is
then fired.

(VOXtrigger).
This example shows how to send a GPO (General Purpose Output) trigger to a third
party radio when audio comes in from an Encore RS701 beltpack. This can be used
to open audio transmission on the radio; equivalent to pressing the Push To Talk
(PTT) button on the radio.
The GPO is triggered by LQ models that have a GPO port; LQ-4WG2, GQ-R2WG8
and LQ-R2W4+4WG4.
Note: For this configuration Link Group must already be established. See Creating a
Link-Group on page 48 for more information.
