Background: A Local Area Network (LAN) is a group of computers in a venue that 
share data, either through cables or via wireless transmission. Ethernet is a popular 
LAN communication protocol for PCs. An audio network is a Local Area Network 
made of audio devices and one or more computers. A subnet is a small network within 
a larger network. For example, an audio network might have two subnets: one for enter-
tainment audio, and one for paging.

One use of an audio network is to control and monitor power amplifiers on stage from a 
computer at Front-of-House. You can set amplifier levels, adjust crossovers, measure 
speaker impedance, check for overheating and clipping, all from the house mixing con-
sole.

You need a way to send computer commands to several audio devices at once. This is 
done with an Ethernet switch, which is something like an audio Y cable or distribu-
tion amp. The computer, and all the audio devices, connect to the switch as in Figure 
9.1.

TCP/IQ  is a network protocol that allows you to control and monitor certain Crown and 
BSS audio products on an Ethernet network. HiQnet lets you control and monitor cer-
tain Harman products (including Crown) on an Ethernet network. Figure 9.1 shows a 
typical HiQnet or TCP/IQ network.

TCP/IQ and HiQnet audio networks offer many advantages:

• Use of “off-the-shelf” network hardware. TCP/IQ and HiQnet use standard 
hardware commonly used in the computer industry, making it both low-cost and readily 
available.
•  Better Performance. Meters display faster in realtime because the network is wide 
bandwidth.

HiQnet and TCP/IQ provide these functions:

•  Quickly find all HiQnet components connected to the network.
•  Synchronize multiple control points on a network.
•  Control and monitor components on different Local Area Networks (LANs) through 
the use of an IP router (explained later).
•  Upgrade firmware via the network.
