Page 7: Installation
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. -
Page 8: Install The Wiring
3.2 Install the Wiring Connect the IQ-MC module to the IQ system via the IQ Bus. The IQ compo- nents 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. - Page 9 IQ-MC Modules The following examples show how to connect the MC-IQ to other IQ components: Figure 3.3 RJ-45 Output to Barrier Block Input Figure 3.4 RJ-45 Output to Din Input Figure 3.5 RJ-45 Input to Barrier Block Output Page 9 Reference Manual...

In addition, the IQ-MC Load Su- pervision feature has the ability to verify the status of the loads in real time. The IQ-MC module uses Crown’s IQ2 protocol. This makes it possible for a user to design custom graphic display modules to control and moni- tor the unit with IQ2-compatible IQ software. -

trolled via software or may be pro- grammed to switch when a fail con- dition is present on any channel.* The high-impedance (10 K ohm) AUX input can sense logic signals and can be programmed to activate system mute or report fault condi- tions when a logic high is present. -

(See Section 4.3.14) * This is assumed to be 70V or the rated 8-ohm output. ** Thermal Headroom on your Crown am- plifier may be labeled Junction Tempera- ture Simulation (JTS). *** See the amplifier’s Reference or Owner’s Manual for more information about JTS and how it works. -

4.3.6 Ready/Standby Control Each channel’s output relay can be independently turned on and off. 4.3.7 Signal Mute The output signal of each channel can be independently muted. This function typically provides 80 dB or more of attenuation. 4.3.8 Polarity Inverter The polarity of the input signal of each channel can be independently inverted. -

On/Off: Turns the limiter on or off. Average Power Threshold: The threshold is adjustable from 10 to 1000 watts.** Nominal Load Impedance: The nominal load impedance is settable from 1 to 1000 ohms, and should be set to correspond to the nominal impedance rating of the load con- nected to the respective channel. -

This procedure should work well for most applications. However, some applications can be a little more difficult. Some very low-level and/or low duty-cycle signals may not ad- equately “test” the load. Lab and situation testing have shown output levels as small 40 dB below rated amplifier output to be enough for most low-impedance loads. -
