The transmitter's industry-standard thread mount also allows it to be used with additional Audio-Technica capsules (available separately) and other compatible capsules. Its multifunction button can be programmed to perform a specific function when pressed and held: mute the audio; mute the audio even when the transmitter is locked; turn off RF transmission; or switch to a preselected backup frequency to avoid interference. The multifunction button can also be disabled. The transmitter housing is made of metal with an integral antenna and an OLED screen. Each handheld transmitter includes a heavy-duty Quiet-FlexT stand clamp.
