Brilliant is how the Sony PCM-D50 handles "overs." It's always
recording a backup stereo track 10 dB or so below the primary
recording.. When it detects an overload, it automatically replaces the
overloaded portion with the backup track and normalizes it so that it
goes to full scale, but not clipped.
Just out of interest, does it do the trick by just reducing the digital
output from the ADC or does it have an analogue signal path with levels
10dB below the one in use?
I don't know, but I screamed really close to the mics with the input
gain up full and what came out wasn't clipped. I suspect that it's
possible to overload the front end feeding the "emergency" track at some
point - it's not absolutely foolproof, but the record level control
appears to work right at the input stage, or else it has a phenomenal
amount of headroom. I could put +28 dBu or so into the external line
inputs, turn the input level control so that the meters were below full
scale, and not have clipping.
