Crown IQ2SLM8 Module The IQ-SLM-8 System and Load Monitor is a versatile eight-channel monitoring device with a built-in test signal generator. It can monitor the impedance response of eight different loads (such as loudspeakers) and/or the frequency response of eight line-level or high-level outputs. When a load or output is tested, the unit will compare the results to a reference measurement stored inside its memory and display either a pass or fail signal with its two-color indicators on the front panel. The unit also sends pass/fail information to an IQ System if one is connected. The pass/fail tolerance of each channel is set individually. The IQ-SLM-8 (we'll shorten the name to SLM-8 for the rest of this manual) can serve as a valuable troubleshooting tool to help you identify problems before they become severe. For example, with an impedance test, you may be able to locate a damaged loudspeaker before it fails completely. In addition, the SLM-8 can serve as a powerful security tool to help you prevent unauthorized changes to an audio system. For example, you can monitor the frequency response of an output to verify that both level and equalization settings have not been changed. The SLM-8 is also an IQ2-compatible component. This means it can be both monitored and controlled by a Crown IQ System. However, with its front-panel pass/ fail indicators and its ability to initiate a test with an external switch, it can also be used in a stand-alone mode after it has been configured by an IQ System (a host computer running appropriate IQ software and an IQ interface is required for setup).
