To add to what Corey suggested, any
time I see a post that indicates the repeater as tinny audio, the
first thing I suspect is the audio is double - pre-emphasized.
This can happen two ways:
The audio feeding the transmitter is already pre-emphasized, but
the transmitter is doing it again. Audio placed in to the MIC
input will almost always add pre-emphasis to the applied audio.
If you are feeding a radio that applies the pre-emphasis as part
of the hardware, then don't add pre-emphasis in the configuration
file.
It can also happen with some hardware (no necessarily app_rpt)
when the receiver audio never gets de-emphasized and that audio is
fed to a transmitter that applies pre-emphasis as part of the
hardware.
Both of these will result in double pre-emphasis and the audio
will sound tinny.
More on this subject is available on RB.
