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 checking your connections or making sure that the audio and video components connected to the USP-1 are on and fully operational. The following information will help you deal with common problems you may experience during initial use of your unit. If problems persist, contact Emotiva’s service department for assistance.

No Sound (from one or more full range speakers)

•Speaker cables may have come undone from the amplifier. Turn off your system and check the speaker cables, and tighten the binding posts.

•Audio output cables that connect USP-1 to the amplifier(s) may not have a good connection. Turn off your system and check all audio cable connections.

•An audio cable may have an internal break. Switch cable with a different channel to see if the problem migrates to a different channel or stays in the affected channel(s).

•The correct input is not currently selected.

•The mute switch is on.

•The outputs on high pass and low pass channels may be accidentally reversed. Check that the correct output feeds the intended amplifier.

No Low Frequency (or poor output)

•The powered subwoofer’s amplifier is off or its input level controls are set low.

•Adjust the crossover on the subwoofer or USP-1.

•Adjust the physical location of your subwoofer.

Sound Drops Out with CD or DVD Playback

•Make sure the disc is not dirty or scratched.

•Some inexpensive players and changers tend to mistrack more often than you would like.

Remote Not Working

•Make sure the AAA batteries are not dead or installed incorrectly.

•Make sure that the USP-1 front panel receiver window is not obstructed.

External Amplifier(s) Shut Down (Often or Prematurely)

•Make sure each speaker’s average impedance is not less than your amplifiers can safely handle.

•The amplifier(s) have good ventilation, no vents are covered.

•Try using your left and right speakers with the High Pass filter, allowing a more efficient use of the amplifier’s power.
