AMB-5 / SMX-6

  IQ Mixer/Multiplexer

Crown Bus loops, 1 and 2, and an IQ–SMX-6 is to be
installed into loop 1 and given an address of 114. No
other IQ–SMX-6 can be given the same address in
loop 1. However, an IQ–SMX-6 in loop 2 can have the
same address.

Different IQ components in the same Crown Bus loop
can have the same address. For example, both an IQ–
SMX-6 and an IQ–AMB-5 can use address 114 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 never
be used.

3.2.2 Connect the mixer/multiplexer to the IQ System
via the Crown Bus

The IQ components in a Crown 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 3.10.

There are three different types of connectors used for
Crown Bus wiring on IQ components. These include
DIN connectors,  RJ-45 connectors, and removable
barrier strip plugs. IQ mixer/multiplexers use four ter-
minal removable barrier strip connectors that accept
plugs like the one shown in Figure 3.4.
