Is the XL H1 in HDV mode capable of recording 16 bit 48 Khz to all 4 of its audio channels or is it just 2 channels like DV? Whatever the answer is I'm assuming that all 3 XL H1 series cameras would be the same. I do know that in DV mode 4 channel recording is restricted to 12 bit 32 Khz.
Someone said that you can record to all 4 channels at the higher quality setting but the XL H1 manual doesn't talk about 4 channel recording in HDV mode. Only 2 channels.
