measurement software AND a correction plug-in to greatly improve the audio monitoring accuracy of speakers in any studio or room listening environment in an elegant, portable, affordable, easy to use and extremely professional solution.

ARC System 2.5 now includes a brand new, ultra-precise MEMS measurement microphone that perfectly works in synergy with ARC's correction software (previous ARC mic models will be supported.) The microphone is built around an omnidirectional, high precision MEMS capsule that ensures maximum response accuracy and stability over time.

In contrast to standard condenser measurement microphones, which are potentially subject to subtle frequency response variations over time, MEMS technology is far more stable.



Thanks to the manufacturing process behind them, MEMS microphones boast extreme resistance to humidity and temperature variations as well as increased durability.
This means that they are much more forgiving to "professional abuse" and you can carry them around without worrying about damaging them. Also, all microphones units that are manufactured following this procedure, share the same degree of accuracy with near-zero variation in terms of final performance from unit to unit.

As a result, all measurement processes will always be spot on, repeatable and reliable even after longer periods of time.

Did you know The ARC System 2.5 MEMS microphone makes for a great additional OMNI pattern recording tool you can add to your mic arsenal! Use it to capture the natural ambience of a studio/room while recording vocals, guitars and other acoustic instruments.
