• Check that the interconnect cables to the amplifier do not have any broken connections. The best way to
do this is to substitute a known good connection for the suspect connection. If you reverse the cables and
the problem goes away, the cable may be damaged or broken. This is possible even if you can’t physically
see the break as the strain for pulling on audio cables can sometimes break the wire internally.
Ground loop isolators are available for both audio and video devices as well as the cables that inter-
connect those devices. You can ask your Emotiva Dealer for assistance. 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, 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 IPS-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 IPS-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.
One or more RED lights on the Front Panel are On
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 but-
ton 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.
For any other problems, please contact Emotiva for assistance.
