Emotiva LPA-1 manual Other Probable Causes of Noise, Problems with the whole A/V System

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 effi 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.
