Page 8: Welcome
IQ mixer/multiplexers are intelligent mixers with special signal routing capabilities. Their intelligence stems from a powerful onboard microprocessor which enables them to be controlled by a Crown IQ System Each input and output can be individually controlled and, with their distributed intelligence tinue to operate even when an IQ System is not con- nected. -

Page 11: Connecting To The Crown Bus
This flexibility is a great strength, en- abling a Crown Bus loop to be wired with either fiber optic cabling or with inexpensive twisted-pair wire, whichever the installation requires. A single IQ System can have more than one Crown Bus loop. -
Page 12: Connect To The Iq System Via The Crown Bus
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. -

Page 26: Paralleling Inputs
(P), select it only at the first input. Switch all other parallel inputs to mic (M).* * When mixer inputs are paralleled, the total input impedance will drop by 1/ N where N is the number of inputs to be connected. Depending on the signal source, this may place a limit on the number of possible outputs. -
Page 27: Using The Aux Port
To do this the AUX connector might be used to close a relay. The relay would then turn the fans on or off. This is shown in Figure 6.14. The solid state relay shown (Crown part number D 7308-7) can be ordered from the Crown Parts Depart- ment. -
Page 28: The Mixer/Multiplexer As Iq Interface
* Because Loop IQ Interface and CLN use the same DB9 connector, they cannot be used at the same time. This means that IQ–SMX-6s to be used in a CLN will need to be connected to a Crown Bus via an external IQ interface for setup. -
Page 29: A Closer Look At Crown Bus Wiring
However, there are extreme situations when fiber optic wiring is recommended. For example, locating a Crown Bus loop next to an AM radio trans- mission line may require fiber optic cabling. An ex- tremely long Crown Bus loop distance may also require fiber optic cabling. -
