240V AC, 50/60Hz. Use the mains cable appropriate to your region as supplied with the amplifier and connect it to a switched mains supply.
SmartAmp amplifiers have no mains power switch and are operational as soon as mains power is connected. Ensure that all signal, GPIO and output connections are made and that all DIP switch options are selected appropriately before connecting the amplifier to mains power.
NOTE
SmartAmps are Energy Star compliant and will sleep when not in use to minimise energy consumption. The amplifier will wake up from standby when an input signal of -57dBu or above is present.
If using in conjunction with a paging system, we would recommend playing background music through the system to ensure the amplifier remains active. After 25 minutes without a signal the amplifier will return to standby mode.
