Shure AD651B Talk Switch
Threaded between the cartridge and the body of an Axient Digital ADX handheld transmitter, the Shure AD651B adds a talk switch, a push-button that reroutes AD4 receiver outputs.
In the receiver’s channel menu, each output (XLR, TRS, AES3, or Dante) is set on or off for the pressed state. Pressing and holding the button switches the outputs to that routing, and releasing it returns the normal signal paths.
The switch is assigned in the transmitter’s Talk Sw menu and runs on one SR44 coin cell, sold separately. The housing is aluminum with a molded plastic button, and it weighs 57 g without the battery. For cold conditions below 0 °C, Shure offers the AD651FOB.
