recognized. Once this fault occurs, perform the following:
o Make sure there is a good connection between the speaker and the IDA8C/S.
o Ensure the speaker is a working one.
o Check the gain of the amplifier, maybe the value has changed after getting the reference.
If all of the above actions have been checked but the amplifier still receives a fault that is too
high, replace the amplifier.
Amplifier Too Low:
If Measure < (Full Unloaded Reference x (100% - Tolerance%)), an Amplifier Too Low fault is
recognized. Once this fault occurs, check the following:
o Check if the signal going into the amplifier is too large, some amplifiers have an indicator
"Overload". Check this indicator.
o Check if the speaker is working or damaged.
If all of the above have been checked but the amplifier still receives a fault that is too low,
replace the amplifier.
If this fault generates after the speaker configuration is changed, you can perform a reference
again to get new values for a reference.
Amplifier Fail:
Measure < (Unloaded Reference / 10), once this fault is happen, check the following:
o Check if the amplifier power is on.
o Check if the gain of the amplifier is set to 0. If it is, set to a suitable value.
o Check if the wires between the amplifier and IDA8 have a good connection.
If all the above have been checked completely but still the amplifier receives a fail fault, replace
the amplifier.
