18 Troubleshooting Guide The Emotiva USP-1 is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checki ng your connections or making sure that the audio and video components connected to the USP-1 are on and fully operational.
19 • Check that the amplifier(s) power output is a good match for your speake rs. If your speakers are inefficient, consider using larger power amplifiers.
20 • If the hum is heard from within the USP-1 and not through the speakers, this m ay also be caused by interference on the AC or DC lines. The power transform ers may turn this interference into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating, so try m oving the USP-1 to another shelf.
