Step 4- Enjoying your Speakers
1. Turn on the rear panel volume/power knob and set the
volume control to about 3 o'clock.
2. Turn on your audio source and adjust the volume to your
desired listening level.
Two audio sources may be connected to the speakers at the
same time. To adjust the volume, we recommend using the
individual volume controls on each source.
We recommend using a high-quality surge suppressor and/or AC
line filter on all electronics equipment.
