Trouble Shooting
Input overload. Check that the attenuation switch on
the transmitter is set to -20dB
Overload in the mixer input. Reduce output gain on
receiver and/or reduce input gain on mixer.
If headworn, check the position of the microphone
capsule.
Check that the transmitter is on.
Is the battery OK? Try another one.
Has the rubber transit cover been removed from the
battery?
Has the battery been inserted correctly? Check polarity
Check that the battery is properly installed.
Inspect the transmitter aerial for damage and loose
fitting.
Check that the transmitter aerial is straight and as
vertical as you can manage.
Body absorbtion of RF. Check that the transmitter
aerial is not stuck to the skin with tape. Avoid contact
of aerial with skin if possible.
A faulty capsule. They can fail by giving low gain.
Substitute a good microphone from another pack, or
use the spare if only 1 pack is in use.
A level mismatch, where a low signal is amplified by
the next stage increasing background hiss to audible
levels. Below are the most likely solutions to this.
Reduce input gain on mixer, increase receiver output.
Set attenuation setting to high on tranmitter. If disto-
tion results, return to original setting.
Some actors (and some locations!) produce a lot of
sweating. Ingress of sweat can affect performance.
Consider re-positioning the pack on the actor.
Take a child's balloon and trim with scissors so that
you can encase the transmitter in a waterproof cover-
ing.
