Re: Dynamic Range/ Signal to Noise
Real world audio specs are rarely given by camera makers and less rarely acurate. Panasonic should be bragging about the DVX100 audio specs but they don't.
Jay Rose did some tests for DV magazine. Here are his results...
Frequency response was remarkably smooth: 25 Hz to 18 kHz ± 2 dB, with a couple of insignificant, narrow dips at 130 Hz and 280 Hz. Distortion (THD+N) was 0.14 percent for line-level inputs, rising to 0.18 percent for a -50 dBu mic. With a +14 dBu input - well into the headroom of any professional mixer - distortion was only 0.3 percent. Signal-to-noise ratio, relative to a 1 kHz signal at -12 dBFS, was -60 dB for line and -58 dB for mic inputs. This translates to a 72 dB dynamic range, acceptable for broadcast and some theatrical purposes.
