3 Installation
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).
SW1
1 2 3 4 5 6 7 8
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.
Reference Manual
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
ON
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.
* Note: All IQ PIP™ modules (IQ-PIP-USP2,
IQ-PIP-MEM, IQ-PIP-SMT, etc.) are consid-
ered the same type, and so may not share
the same address on the same IQ Bus.
