The

IQ-MC4A and IQ-MC8

connect CTs 4200 and CTs 8200 am­plifiers to the IQ Bus of an

, allowing the amplifier to be

tem

controlled and monitored via IQ.

The IQ-MC module is an
component. This means it supports
Crown’s IQ2 protocol and requires an
IQ System with an IQ2

interface. IQ2
ables users and third parties to de­velop custom software objects to con­trol and monitor IQ2 compatible com­ponents like the IQ-MC module.

IQ-MC Modules

Each IQ-MC module includes an IQ
address switch allowing the unit to

have a unique address on the IQ Bus.
It is powered by the amplifier and
includes a memory backup feature
that enables the amplifier to resume

operation with all of its settings intact
after a power outage.

We strongly recommend you read all
the instructions, warnings and cau­tions contained within. Also, for your
protection, please send in the war­ranty registration card today and save

the bill of sale since it is your official
proof of purchase.

3 Installation

IQ-MC Modules

3.1 Prepare the IQ-MC
Module

First, turn off and unplug the amplifier.

Set the IQ address switch S1. By
giving each IQ component a unique
address, it can be individually con-

trolled and monitored. Whenever the
IQ System wants to send a command
to just one IQ component, it first sends
its address and then the command
down the IQ Bus.

S1 has eight segments because it
actually contains eight tiny switches

inside. The word “ON” is printed on
the switch along its lower left side to
indicate the ON position and the
switches are numbered along the
bottom (Figure 3.1).

124

VALUE

SW1

12345678

Figure 3.1 Address Switch (S1)

Each of the eight switches in S1 has a
value which doubles as the switch
number increases. For example
switch 1 has a value of 1; switch 2 has

a value of 2; switch 3 has a value of 4;
switch 4 has a value of 8 and so on.

8163264128

ON

The address is determined by adding
the values of all “ON” switches. In

Figure 3.1, switches 1, 3, 4 and 7 are
on. Simply add the values to find the

address: 1+4+8+64=77.

A convenient series of IQ address
tables are included in Section 6. The
tables show the switch settings for all
250 addresses.

No two IQ components of the same
type which are connected to the same

IQ Bus can have the same address.*
Suppose, for example, an IQ System

has two IQ Bus loops, 1 and 2, and
this IQ-MC module is to be installed
into loop 1 and given an address of

77. No other IQ-MC modules can be
given the same address in loop 1.

However, an IQ-MC module in loop 2
can have the same address.

Different IQ components in the same
IQ Bus loop can have the same ad-

dress. For example, both an IQ–USM
810 mixer/processor and an IQ-MC

module can use address 77 in the
same loop.

A valid IQ address is any number from
1 to 250. Do not use a number higher
than 250 since they are reserved for

special use. An address of “0” (zero)
should only be used for “stand alone”
mode. Setting the address switch to

“0” disables the IQ Bus port.

Reference Manual

* Note: All IQ PIP™ modules (IQ-PIP-USP2,

IQ-PIP-MEM, IQ-PIP-SMT, etc.) are consid­ered the same type, and so may not share
the same address on the same IQ Bus.

3.2 Install the Wiring

Connect the IQ-MC module to the IQ
system via the IQ Bus. The IQ compo­nents in a IQ Bus loop are wired
sequentially. The loop begins and

ends with the IQ interface. The output
of one IQ component “loops” to the
input of the next and so on as shown
in Figure 3.2.

IQ Interface

IQ Component

There are three different types of con­nectors used for IQ Bus wiring on IQ
components. These include DIN con-

nectors, screw terminal plugs, and
RJ-45 connectors. The IQ-MC uses
RJ-45 connectors that accept stan-

dard RJ-45 plugs like the one shown
in Figure 3.6, allowing the use of in­dustry-standard straight-thru type
network cables. The right RJ-45 con-

nector is used for input and the left RJ­45 connector is used for daisy output.
