Sennheiser MAS 1 Microphone Activation Button

The MAS 1 is the table-mounted activation button for SpeechLine Wired installs. It drops through a hole in the conference table and sits about a third of an inch proud, so a delegate can take their own microphone on and off without anyone touching a mixer.

It wires on 5-pin XLR and runs on P12 phantom, in a 1.12 inch diameter body. Black and white versions match the two standard SpeechLine finishes.
