AC Line
The VRM10s/VRM12s/VRM15s operate from a 115 VAC/60Hz power line.
The VRM10sCE/VRM12sCE/VRM15sCE operate from a 230 VAC 50/60Hz power line. Connection is
made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly
grounded (earthed) receptacle should be used. If a grounded circuit is not available, do not break off
the ground pin; use the proper adapter plug for a two wire receptacle with the grounding plug suitably
connected to earth ground.
Important: The power line fuse is mounted on the rear panel. If this fuse blows, replace it only with
the same type and rating as indicated in the parts list.
LED Indicator
Amplifier operation is monitored internally and has a
status LED. This indicator can be used for system
troubleshooting. The LED will illuminate GREEN if
signal is present at the subwoofer’s input. The LED will
turn off and the amplifier will go into sleep mode if
signal is not present.
Break-in and Warm-up
We recommend initially breaking in the subwoofer for approximately 8 hours with musical information
to establish the subwoofer’s natural bass response.
Cleaning & Maintenance
There is no requirement for regular maintenance on the electronic components of the subwoofer. If the
cabinet or woofer becomes soiled, it can be cleaned using a damp, soft cloth. If the subwoofer is locat-
ed in a particularly dusty environment, cleaning the inside with compressed air or vacuuming every 18
to 24 months is sufficient.
