    New DIY Mid High (90deg) - AKA PM90

    The explanation of Polarity/Phase adjustement in the user manual is 0 to none. But it's definitely not a simple delay (delay is described in the next chapter, 4.5.5) so should be All Pass Filter with the phase control for all frequencies. Unfortunately for me I don't have enough knowledge of DSP...

    New DIY Mid High (90deg) - AKA PM90

    it looks like DCX2496 should support phase correction. From the user manual: It's also possible to use CC caption on youtube, with auto-translation to english. I found is useful more than once.

    New DIY Mid High (90deg) - AKA PM90

    For Selenium the 2nd harmonic distortion is >10db lower compared to BMS4594. It is at least -30dB (approx. 108dB-75dB=33dB) which translates to 2% THD or less, in HF region.

    Yes, it's from the datasheet, and on the picture 2nd harmonic is only ~10dB lower so yes, I noted it's rised 10dB

    New DIY Mid High (90deg) - AKA PM90

    Hi Guys. I don't want to be a party pooper but am I the only one who is concerned about really high 2nd harmonic distortion of BMS4594HE in the high frequency region, where it's most noticeable/audible? The THD is -20dB or 10%, huge! It's shown in green on the picture There is a research that...
