Questions about your FP410 installation? This section lists the most common questions asked about Shure’s automatic microphone systems. Maybe your question is among the fol- lowing. If not, contact Shure’s Customer Service Department.
Q. Why don’t I get any sound output from my FP410?
A. Assuming that your power amp, tape deck, speakers, etc. are good, possibly it’s because:
The Channel or Master Gain controls are turned down,
A microphone is not connected,
A
The FP410 isn’t plugged in or doesn’t have batteries in- stalled, or
The Power switch isn’t on.
Check these items and make the required correction. Q. Still doesn’t work. Why?
A. Maybe you have a defective microphone or cable. While lis- tening to headphones plugged into one of the
Q. Why does a microphone turn on or off erratically, causing speech dropouts?
A.Excessive room noise (such as from

13 dB (modifiable function switches up). Difficult situations may be aided by changing the Hold Time from 0.4 to 1.0 sec- ond (modifiable function switch down).
Q. Why am I getting howling through my loudspeakers?
A. For the same reason that howling is present in any PA sys- tem: your mics are picking up the speaker sound and reampli- fying it. Move the speakers or mics, or turn down the gain con- trols, to avoid the howling. Automatic operation does provide more output level before howling than manual operation, but the system still can howl.
Q. Why does the FP410 output sound distorted?
A. The Channel, Master or Phones Gain control may be set too high. Set the Channel Gain according to the Operation section. Set the Master Gain to avoid excessive red LED indications on the Output Level meter, or switch the Limiter in. Turn down the Phones control. Check the following equipment levels.
Q. Why does the speech level go up when I switch from Manu- al to Automatic operation?
A. This is normal and proper operation for any automatic mix- er.When switched to Automatic, the FP410 attenuates any in- put channel not being used. Internally, this removes the inac- tive channels from the FP410 mix bus. This action increases the perceived level of any active input channel. For example, the audio gain increase will be 6 dB when going from four to only one activated microphone channel.
Q. Why is one of my four mics very noisy?
A. Assuming the mic is operating properly (you can check this by substituting with another mic), you probably have a con- stant noise source such as
