Audyssey has unveiled the ACM1-X, a specially calibrated microphone designed to work with its MultEQ-X room-correction software, enabling users to take measurements that the company says are equivalent to those of a class 1 reference microphone.
Class 1 is a term used to describe microphones used in professional sound level measurement devices considered to be of precision grade. Compared to class 2 or 'general grade' devices, these microphones have wider tolerance levels at the upper and lower ends of the frequency spectrum producing a more accurate overall response.
Each Audyssey ACM1-X microphone is individually calibrated at Audyssey's lab in Los Angeles before being assigned a serial number and its own unique calibration file. MultEQ-X users who purchase an ACM1-X microphone can log into MultEQ-X and, by selecting the option 'Add New Mic', enter their microphone's serial number. The mic's calibration file is then downloaded and paired with the user's app.
The ACM1-X will only work with MultEQ-X, Audyssey's enhanced software that gives users improved functionality when using the company's MultEQ room equalisation technology.
MultEQ-X lets owners of compatible Denon and Marantz AVRs access advanced controls to tweak their acoustic parameters and display detailed information about their room acoustics.
Key features of the software include the capability to adjust subwoofer levels with slow or super-slow time rates, an advanced frequency response curve designer with a new 'cut-off mode', and complete control over target sound curves for every channel and every preset.
The app costs $200 (around £151 / AU$281) and includes a non-transferable license that entitles a single user to calibrate one specific AVR for the lifetime of that product. A virtual demo AVR is included with MultEQ-X for free.
The Audyssey ACM1-X microphone is available now on Amazon (opens in new tab) at an introductory price of $80 (around £61, AU$110). It's currently showing as out of stock, but available supply for the US is expected soon.
