DO NOT CONNECT THE AC MAINS END OF THE AC MAINS CABLE IN AN
AREA THAT IS WET OR SUBJECT TO CONDENSATION OR DAMP
CONDITIONS!
The AC Mains end of the cable assembly uses an “in line” GFCI device (115 V
AC) or a PRCD device (230 V AC). DO NOT disconnect this device!
NOTE: The AC Mains cable is an extension cable. It is a high-quality cable with
low line loss. Connecting the AC Mains cable to another extension cable will
produce additional line loss and can result in low ac mains voltage at the POPS
amplifier module. It is not recommended that additional extension cables be
used with this AC Mains connector.
Once the AC mains cable is securely connected to the amplifier and AC mains
supply, POPS15a may be powered up. A good practice is to make sure the audio
levels on the mixer’s output (or other source output) are reduced or muted prior
to applying power to POPS15a.
NOTE: When power is applied to POPS15a and the unit is turned on there is a
short delay before the pilot light illuminates.
