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.
