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.
