The MC70 is a general purpose audio cable used to deliver a line level audio signal from any audio source with a TRS jack to a Lectrosonics transmitter with a 5-pin input jack. The tip of the TRS connector is wired to Pin 5 of the TA5F connector.

Since the cable is simply a passive connection, it will work with all versions of current and legacy Lectrosonics transmitters with a TA5F input jack.

Overall length is 14 inches.
