Ground loop isolators are available for audio lines and video devices. If you need assistance, contact
your Emotiva Dealer. Although this is not always an ideal solution, the grounding differences between
certain home entertainment components sometimes require ground loop isolators. This is the
exception rather than the rule.
Other Probable Causes of Noise
Speaker noise may also be caused by interference or noise on your AC line. Make sure there are no
large appliances sharing the line, or halogen lamps or light-dimming Triac devices.
• Try connecting your system to another AC socket on a separate line.
• If the hum is heard from within the LPA-1 and not through the speakers, this may also be caused by
interference on the AC or DC lines. The power transformers may turn this interference into an audible
noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the LPA-1 to
another shelf.
• Try moving your components further away from the TV, especially if you ever notice the screen has
changed color in the area closest to the component.
• If you have very high ef ciency speakers, these may tend to reveal noises which other speakers do
not.
One or more RED lights on the Front Panel are Blinking
Each RED light indicates a fault condition for the corresponding power module. A fault condition is
one or more of the following:
• Excessive Operating Temp
• Excessive Current (Short Circuit)
• DC on the Outputs
An excessive temperature fault can be reset by allowing amp to cool and cycling power on/off button
on the front panel. Excessive current (short circuit) can be reset by removing the cause of the short
and cycling power on/off button on the front panel. DC at output is a possible fault condition that is
equipment related and requires technical assistance. Please contact AV123 if you have repeated
problems causing the RED front panel light to flash that are NOT thermal or short circuit related.
