ARC System 2
Chapter 2 The ARC System 2 components
2.1 The ARC MEMS Measurement Microphone
The ARC MEMS Measurement Microphone provides an overall higher
quality when compared to low or mid-priced measurement microphones.
Measurement microphones usually exhibit a near flat frequency response at
the expense of poor sensitivity and a noise level that is too high for quality
recording.
The ARC MEMS Measurement Microphone exhibits a compensated frequen-
cy response, and at the same time, its sensitivity, noise level and max SPL are
extremely good. This means that you will be able to use this mic not only to
measure your room but also to record various acoustic sources.
In addition, this microphone is omni-directional. This makes the proximity
effect found in typical studio cardioid microphones disappear and instead
sounding very open and natural. This aspect makes it even more useful
when you consider that in entry-level studios, omni-directional micro-
phones are usually not an option
Technical Specifications:
• Type: high performance MEMS element
• Polar pattern: omnidirectional
• Compensated frequency response: 20-20,000 Hz
• Sensitivity: 38 mV/Pa (1kHz, 94dB SPL).
• Signal to Noise Ratio: 64 dB(A).
• Max SPL: 124 dB SPL (10% THD).
2.2 The ARC 2 Measurement Software
The ARC 2 Measurement software is a standalone application that analyzes
your speakers and room system and automatically calculates the best pos-
sible correction that will be applied later by the ARC 2 Plug-In.
The ARC 2 Measurement software works by sending test tones to your
speakers and at the same time recording the signal captured in the room by
the ARC 2 Measurement Microphone.
