The amber Enable indicator is provided to show that the amplifier has been turned on (or enabled), and that its
The amber ODEP indicators confirm the nor- mal operation of Crown's patented Output Device Emulation Protection circuitry. During normal operation, they glow brightly to show the presence of reserve
The ODEP indicator for the affected channel will turn off if a
The green Signal/IOC indicators show sig- nal presence and distortion. As signal presence indicators, they flash with normal intensity in sync with the output audio signals. As IOC (Input/Output Comparator) indicators, they flash brightly if there is any difference between the input and output signal waveforms greater than 0.05%. Because transient distortion hap- pens quickly, a 0.1 second "hold delay" keeps the indicators on long enough to be easily noticed. The IOC function essentially provides proof of
