ALC (Automatic Level Control)
ALC feature prevents the repeater from exceeding its maximum output power by reducing the gain
automatically. ALC is used to adjust the gain to an appropriate level for a range of input signal levels.
ASD (Automatic Shutdown)
Automatic shut down protects the repeater from oscillation or excessive input signal and eliminates
any degradation to the network.
There are three parameters: ASD Level, ASD Time, and ASD Iteration.
If the output power exceeds higher than the “ASD LEVEL”, the repeater will shut down for “ASD
TIME” seconds and it will turn the amp back on to measure the output power again. If this repeats at
“Iteration” times, the repeater will shut down completely.
