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 efficiency 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 amplifier 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 amplifier 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/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 Emotiva if you have repeated problems causing the RED front panel light to illuminate that are NOT thermal or short circuit related.
