A positive (+2.5V towithout having to physically remove it from the table. This +12V) signal applied to the DSP control port will simultaneouslyis achieved by simply pressing the top of the microphone activate all ARM motorised microphones connected to the ARM-Cdownwards until it locks; then by pressing the microphone again (control unit for ARM microphones). it will raise itself back to its original position above the surface of the table.
