Room Correction – EZ Set EQ
Loudspeakers and room interaction inevitably introduce unwanted coloration to the 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 for all MA
series AV Receivers. The calibration collects room acoustics data for each speaker group in under 2 minutes and
can be done by anyone, using an iOS or Android mobile device.
Room Correction using the EZ Set EQ app should be performed after system setup is completed. The system
setup is considered complete after the initial system configuration is performed (Menu > Setup > Speaker Setup >
Types, Distances and Level) and the system is fully functional.
HOW DOES EZ SET EQ ROOM CORRECTION WORK?
Using a microphone to analyze the audio system and room, EZ Set EQ builds an acoustic model of the listening
environment. The built-in microphone of an iOS device can be used for the calibration. For Android users, JBL
recommends using a third-party microphone for the best results since every Android device has different a
microphone/frequency response.
Recommended calibrated microphone for Android users: Dayton Audio iMM-6C USB-C
EZ Set EQ primarily addresses room interactions in the low frequency bands, that way it has minimal effect on
overall loudspeaker voicing. The low frequency response can be adjusted according to the loudspeaker’s natural
low frequency extension to avoid boosting lower than the speaker can handle, and by the size of the room.
EZ Set EQ does not affect delay or level adjustment; so, it is recommended to make the necessary adjustments
manually prior to using the room EQ app.
USUNG SUBWOOFERS
If your system includes active subwoofers, you may need to set the subwoofer output level/gain control set to a
higher or lower value.
EZ Set EQ does not calibrate the subwoofer separate from the main loudspeakers. The system is calibrated full-
range with the subwoofer output active to capture the “system” acoustic data to blend the subwoofer more
effectively for each channel. In this way, the system takes a snapshot of the combined performance of the
loudspeaker and subwoofer system integration.
You may ask - “What if I want to listen to traditional 2-channel Stereo without a subwoofer?”
EZ Set EQ allows correction of the Front Left and Right loudspeakers both with and without a subwoofer. In this
case, you will take two measurements of the Front Left and Right loudspeakers, labelled as Front (Small) and
Front (Large). The system will automatically select the Front (Large) calibration any time you change the surround
mode to Stereo 2.0 for optimized full-range 2-channel performance without a subwoofer.
