One Systems POPS SUBa - Manual (Page 9)

On/Off Switch
NOTE: DO NOT CONNECT THE AC MAINS CABLE TO THE POPSSub IF
WATER OR MOISTURE IS PRESENT IN THE CONNECTOR!
POPSSub will operate on any AC mains voltage between 104 volts and 253
volts. The required AC mains frequency is between 50 Hz and 60 Hz.
POPSSub uses a waterproof AC mains connector system. To mate the AC
mains cable with the AC mains connector on the input plate, align the cable end
with the amplifier’s panel connector and push with sufficient force until you hear a
“click” sound that indicates the cable end and chassis end are properly mated.
Support the POPSSub’s enclosure with one hand while performing this
operation. The AC mains connector is shown below. It is located on the lower
portion of POPSSub’s input panel.
