3 Hardware Installation

The installation of an IQ mixer/multiplexer consists of
two major parts: installing the hardware and configur-
ing the software. This manual deals only with hardware
installation. Refer to the appropriate software docu-
mentation for instructions in setting up and operating
your IQ software.

Provide adequate cooling if the unit will be used in a
hot environment. 

It is good practice to allow one

empty rack space (1.75 inches or 4.4 cm.) between
each unit if more than four units will be stacked in a
cabinet.

 Each empty rack space should be sealed

with a blank rack panel.

The hardware installation is divided into 4 steps: 1)
connecting to a host computer 2) connecting to the
Crown Bus 3) connecting the audio inputs and outputs
and 4) connecting auxiliary devices

3.1 Connecting to a Host Computer (Step 1)

An IQ host computer is an IBM

® 

PC-compatible com-

puter which is used is used to configure or control/
monitor part or all of an IQ System. Depending upon
the design of your IQ System, it may or may not require
a host computer during normal operation.

How the mixer/multiplexer will be used will determine
whether or not it will need to be connected directly to a
host computer. If the unit will be connected to the
Crown Bus it will not need to be connected directly to a
host computer. The following circumstances require
connection to a host computer:

• If a Crown Bus will not be used, the mixer/multi-

plexer will need to be connected to a host com-
puter so the software inside the unit can be
configured. Afterward, if manual control is not
required, the host computer can be discon-
nected.

• If the mixer/multiplexer must be configured be-

fore it is installed into an IQ System, it must be
connected directly to a host computer for con-
figuration. The onboard memory of the unit will
maintain its software configuration without it
being plugged into an AC source.

• If the mixer/multiplexer will be used as an IQ

interface for other IQ–AMB-5 or IQ–SMX-6 mix-
ers, it will need to be connected directly to a
host computer.
