Sennheiser e 912 S Boundary Microphone
The e 912 S is a high-quality, pre-polarised condenser microphone with half-cardioid pick-up pattern, acoustically optimized for picking up speech. Due to its unobtrusive, flat design, it is ideally suited for use on conference tables, altars and lecterns.
The e 912 S can be switched on and off via an integrated membrane switch.
Programmable membrane switch
Very unobtrusive due to flat design
Extremely rugged sound inlet basket
Rubber damping plate on base
Mounting slots for mounting the microphone to table tops, lecterns, etc.
Gold-plated XLR connector
Integrated electronics (instead of in-line preamp)
An internal DIP switch bank provides the following features: on/off (factory preset), push-to-talk button (PTT), cough button (PTM) or permanently switched on (ON)
The frequency response curve can be changed via a second DIP switch bank: low cut, low and high boost (factory preset), low boost or linear (see e 912).
The e 912 S has been optimized for picking up speech at relatively short distances, while the sister model e 916 has been designed for instrument pick up. For this reason, the frequency response curve of the e 912 S differs from that of the e 912.
With the e 912 S, you can obtain the frequency response curve of the e 912 by setting the DIP switch to the position lin (linear).
