Loudspeakers and room interaction inevitably introduce unwanted coloration to sound during playback – colorations which are sometimes either difficult or impossible to remove with traditional electronics or room treatments. The free EZ Set EQ app provides easy-to-use room equalization for optimized sound quality.

The built-in microphone of a supported iOS device can be used for the calibration.

Compatible with all models of JBL MA series AV Receivers.

Note: For the best experience, please check your AVR is running the latest firmware.
