Further to that - some observations on this inconsistency Mono -18dB in mono track panned left = -18dB, panned centre = -18dB Mono -18dB in standard track panned left = -21dB, panned centre = -21dB Mono -18dB modified to be stereo (with left channel only) in standard track panned left = -18dB, panned centre = -18dB (panning right will reduce to silence) So PPro automatically reduces level of mono designated track by -3dB in a standard track but does not apply any pan rules when centering mono tracks Stereo -18dB in standard track = -18dB stereo Stereo -18dB in mono track = -18dB dual mono Stereo -18dB modified to be dual mono in 2x mono tracks centered = -12dB dual mono Stereo -18dB modified to be dual mono in 2x standard tracks centered = -15dB dual mono Really I think PPro should pass through the mono tracks at unity when in standard tracks - would be more intuitive & one knows, when mixing, that multiple mono sources will sum and need attenuating.
