■ Spare Microphone for ARC System 2.5/3 The MEMS Microphone, a measurement microphone for ARC System 2.5 and 3, is based on cutting-edge MEMS (Micro Electrical-Mechanical System) technology, which integrates mechanical movements and structural elements onto a tiny microchip. As a result, individual differences in frequency characteristics, etc., caused by the manufacturing process are minimized. Furthermore, this small yet high-quality omnidirectional microphone boasts an unprecedentedly accurate frequency response of ±0.5dB. It is virtually unaffected by humidity and temperature changes and is highly durable, so you don't have to worry as much about damage during transport compared to condenser microphones. This measurement MEMS microphone is also an excellent omnidirectional microphone. It can also be used as a tool to capture the natural ambience of the recording environment. Please try using it in combination with other microphones when recording vocals or acoustic guitars, etc.
