MultEQ-X software works as an add-on to the MultEQ system already embedded in many Denon and Marantz AVRS. Users get complete control over their target sound, with the ability to customize the frequency range and tonal balance of each individual speaker in the system.

A virtual AVR is included with MultEQ-X for free in order to demonstrate the features and settings available. In order to calibrate an AVR, a license must be acquired through an in-app purchase. This license entitles the user to calibrate one AVR for the lifetime of the AVR. Licenses are per-user and per-AVR-serial-number, and are non-transferrable.

More than a sleek interface to the built-in MultEQ technology, MultEQ-X decouples the delivery of technology from the delivery of hardware. It will be the first place users can experience many improvements and advancements to the MultEQ suite of software / firmware room correction that are currently under development.
