    Modified firmware MCU MTCD/MTCE in the part of the presets of the sound processor (Sound Patched)
    thanks to the esteemed @Hal9k_ for advice on creating a topic on the forum for English-speaking users and respected @typos1 and @Wadzio for their help and tips on attaching MCU firmware files to the thread
    link to Russian mirror

    (modified MCU firmware universal for all HeadUnits, but the improvement of sound only for HU without built-in DSP-module, for HU with DSP-module changes do not affect the quality of sound). All the modified MCU firmware are made on the basis of the original firmware of the corresponding suffixes and versions. In order to distinguish the modified versions of the MCU firmware from the original after the version number added the letter index sp (Sound Patched). The following values ​​are displayed:
    -- for the low-frequency band of the equalizer became: frequency 60Hz, Q-factor 0.5;
    -- for the mid-range of the equalizer became: frequency 500Hz, quality factor 0.75;
    -- for the high-frequency band of the equalizer became: frequency 15kHz, Q-factor 0.75;
    -- for loudness compensation: frequency 250 Hz, 5 dB level;
    -- for the subwoofer channel became: the cutoff frequency of the low-pass filter 85Hz, antiphase output

    previous mod versions:
    moved to archive post

    for other suffixes and versions I will gradually add...

    alternate solution from @Wadzio:
    cs-x Mod MCU firmware change presets of the Sound processor only and fully compatible with any Android builds. Alternate Wadzio SoundPatch is fully software solution and similar to 7floor solution without any hardware modification, but need to use change EQ application in Android (please see detail in the thread).
    BD37xx SoundPatch MOD like 7floor
