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 RPA-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 RPA-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 eciency speakers, these may tend to reveal noises which other speakers do not.
RED light on the front panel blinks from blue to red
The RED light blinking indicates the amplier levels are maximized. This is also called “clipping”. Very short
periods of clipping are not serious but extended periods where the light stays red more of the time means
the amplier is being overdriven.
RED light on the front panel is illuminated solid red
The RED light (on solid, not blinking) indicates a fault condition for the power modules. 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/o button on
the front panel. Excessive current (short circuit) can be reset by removing the cause of the short and cycling
power on/o button on the front panel. DC at output is a possible fault condition that is equipment related
and requires technical assistance. Please contact Emotiva if you have repeated problems causing the RED
front panel light to illuminate that are NOT thermal or short circuit related.
