The OPA 15 Active will operate on AC mains voltages of 115 volts to 230 volts. The
required AC mains frequency is between 50 Hz and 60 Hz. The acceptable voltage
range is 104VAC to 253VAC.
The OPA 15 Active uses a standard IEC-type AC mains connector system. To mate the
AC mains cable with the AC mains connector on the amplifier, simply align the plug with
the panel's connector and press the AC mains cable into place. Always support the
OPA 15 Active's enclosure with one hand while performing this operation. The AC
mains connector is shown below. It is located on the lower portion of the OPA 15 Active
input panel.
NOTE: The OPA 10 Active is supplied with two AC Mains cables. Select the cable with
the proper termination for the country specific mating receptacle!
AC Mains panel connector
To disconnect the cable end of the AC mains connector pull back on the molded plug at
the end of the cable, not the cable itself.
NOTE: ALWAYS turn off the AC mains power BEFORE attempting to disconnect the
AC mains cable from the OPA 15 Active amplifier module!
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!
Once the AC mains cable is securely connected to both the amplifier and AC mains
supply, the OPA 15 Active enclosure may be turned on. It is good practice to make
certain that the audio levels on the mixer's output (or other source output) are reduced
or muted prior to applying power to the OPA 15 Active.
NOTE: When power is applied to the OPA 15 Active and the unit is turned on, there is
approximately a 5 to 15 second delay before the pilot light illuminates.
