So contact Telex and ask about a replacement *matching*
transmitter.

Muting the microphone (typically by shorting the audio signal)
should not cause any transients (at least not the noise burst you
hear from turning the transmitter RF off.) Many wireless trans-
mitters have this kind of "silent" mute function.

Is the rack metal? Is there anything in the walls that might be
shielding the RF signal? (Metal siding, wire lath, foil-backed
wallboard, etc.etc.) I'd bet that the receiver will get a better
signal if the antennas were out of the rack. Even if you had
one on either side of the window, etc. (But not close to a
metal window frame.)

You could just "broadcast" you audio on an unused AM or FM
broadcast channel and have people bring their own radios! :-)
This is actually used in some venues, either a Low-Power (100mW
max) transmitter with the event's own audio, or a commercial radio
station who is programming the event, etc.)

So then much cheaper than any kind of reliable wireless system.

Nothing you have described so far explains why they need more
than the one receiving antenna you said is still there?

Its not clear that what you have already is not adequate.
As you suggested, it may just be used incorrectly.
