MICrOPHONE
the tX4500s is fitted with two microphone sockets
– one on the front panel and one on the rear. the
6 pin microphone connector can be plugged into
either socket. In fact, if the situation requires it, two
microphones can be connected simultaneously. the
first microphone keyed takes priority.
Front
the front microphone socket is fitted with a hard
protective cover. the cover is a press fit. to remove
the cover, insert a paper clip or similar into the small
slot in the edge of the cover and lift the cover away
from the panel. retain the cover in case you require
it later on.
