ok i got it, so at +15V minus 3.5V, the acceptable input is up to +11.5V. that's a whopping 0.37dB less than if it were +12V (the minimum spec of NJM5532).
now how do i modify the stereo link of drawmer DL241
the original implementation is a bit cheap because it just uses the INBUFF audio input from channel 1 to control the gain reduction of both channels. it's convenient in a way so that you only need to turn the knobs of channel 1 without the channel 2 causing a mismatch between the stereo channels. but it's not detecting the peaks that are exclusively in channel 2. the INBUFF of each channel can't simply be summed because you want just the peak value to be detected, so the correlated signals would be detected by a disproportionate amount compared to a peak in just one of the channels. i would want something like an analog equivalent of an OR gate, either to the INBUFF audio signals (but then i'd want the negative peaks as well) or allow each channel to run separately but then the control voltages would be combined with some diode setup.
