11. AC Voltage Switch
The unit is set at the factory for 115V U.S. operation; simply connect the included IEC power cord to your wall outlet. For
230V operation, move the voltage selector switch to the 230V position. When operating at 230V the internal fuse
located in the IEC socket should also be changed. In most 230V applications a separate power cord will be required and
is not included.
12. IEC Power Connector
The unit comes with an IEC jack that permits removal of the AC power cord. This allows the flexibility of chang- ing the
power cord for different countries. The IEC socket also houses the main fuse holder. Plug the power cord supplied with
the amplifier into the amplifier and a grounded wall outlet or appropriate surge protector.
CAUTION:
DO NOT plug the amplifier’s power cord into a switched outlet, such as what is provided on some Sur- round
Receivers. If you wish to have the amplifier turn on when the Receiver is powered up, use one of the power modes, such
as Trigger or Audio.
TYPICAL 6 ROOM INSTALLATION
NOTES ABOUT HUM:
While the Amplifier has been designed to minimize the possibility of hum in the audio system, it is still possible that a
hum will occur in rare circumstances. Its safety grounding can create a path for small amounts of 60 Hz energy to travel
through the line-level audio system. While not dangerous, this energy can cause difficulty with the auto signal sensing
circuit, and at the very least will interfere with the quiet enjoyment of your system. The first course of action should be
trying to make sure that all of the audio components are connected to either the same electrical outlet, or at least into
