The ZA-431 and ZA-331 processors can feed preamplifiers via the input. Connect the output of the preamplifier to the input of the ZA that will pass up to 24VDC 60mA automatically. If an antenna without preamplifier is connected, the ZA module will detect there is no preamplifier and will automatically deactivate the power supply.

2.0 Auto-Adjustment Feature for power levels (THIS WILL ONLY WORK UNDER IDEAL CONDITIONS AND IS NOT RECOMMENDED. ADVANCED USERS ONLY) IMPORTANT: For this feature to work correctly INPUT power to all processors must be within 70dBµV to 50dBµV for DVB-T (Digital transmission). If any of the channel powers within the headend exceeds the range of 70dBµV to 50dBµV for DVB-T and 80dBµV to 60dBµVfor Analogue, input level indicator of the ZA module will continue to blink.
