The MPC 67 is an acoustical boundary microphone with many different functions accommodated in a small, unobtrusive housing. Depending on the application, you can choose between three operating modes: On/Off, Push To Talk and Push To Mute. Furthermore, the frequency response can be tailored for use in three modes: linear, 80 Hz bass roll off, 180 Hz bass roll off. The MPC 67 is switched on and off with a noiseless film button. An LED indicator shows the ready-to-talk status. The different functions are controlled by an 8 bit micro controller. Due to its unobtrusive design, the MPC 67 is ideal for tele/video conferencing, round table discussions or distance learning. The MPC 67 RC is available with a remote control: the microphone can be activated by an external switch and an external device (e.g. video camera) can be triggered by a MOSFET output.
