Connecting the Stereo 90 to the power outlet:

Connect the IEC end of the detachable power cord (provided) to the amplifier, and plug the opposite end into the power outlet. It is recommended that the Stereo 90 and your preamp are plugged into the same wall outlet if possible (perhaps using a power outlet strip) to avoid creating a ground loop.

Amplifier Location:

The Stereo 90 depends on natural convection flow patterns for proper cooling. To ensure proper cooling, the unit should be located in a position so that the airflow is not impeded. The unit should not be placed in a fully enclosed shelf, and should have a minimum of 8 inches of free space above it, and 6 inches of free space on either side.
