Dear Sir,

Could you explain what's PerScale and PostScale (0x56, 0x57)?

Thanks!

    Vincent,

    These two registers are part of the THD manager. The THD manager is used to induce digital clipping of the output signal at a lower level than would usually occur because of voltage clipping.

    Pre-scaler (0x57) adjusts the amount of clipping.
    Post-Scaler (0x56) adjusts the power level at which this occurs.

    Regards,

    -Adam
