The audio cables should be wired in one of the following manners: plifier (if provided).
Page 15 IQ – P .I.P . – DSP Programmable Input Processor with DSP for IQ Systems Reference Manual 4 Operation With an IQ–P.I.P.–DSP module, your Crown amplifier can be monitored and controlled from a remote location through the use of an IQ System .
Page 16 IQ – P .I.P . – DSP Programmable Input Processor with DSP for IQ Systems Reference Manual 4.8 Polarity Inverter The polarity of the input signal of each channel can be independently inverted by the IQ System . 4.9 Input Signal Attenuator An attenuator is available at the input of each channel to control the input signal level.
Page 17 IQ – P .I.P . – DSP Programmable Input Processor with DSP for IQ Systems Reference Manual output limiters are controlled by the IQ System and has five parameters: Output Limiter: Turns this function on/off. Threshold: Sets the threshold, in dB, above which the limiter acts.
Page 18 IQ – P .I.P . – DSP Programmable Input Processor with DSP for IQ Systems Reference Manual level would indicate a sudden decrease in the load impedance—such as a shorted speaker cable or shorted loudspeaker. There are two parameters which control this feature: ODEP Short Detect: Turns this function on/off.
