Hugh Robjohns has been Sound On Sound's Technical Editor since 1997. Prior to that he worked in a variety of (mostly) sound-related roles in BBC Television, ending up as a Sound Operations Lecturer at the BBC's technical training centre.
He continues to provide audio consultancy and bespoke broadcast audio training services all over the world, lectures at professional and public conventions, and occasionally records and masters acoustic and classical music too!
Could you clarify the difference between floating- and fixed-point 32-bit operation in the digital domain. I know that floating-point systems allow for data to be handled at word lengths above 24-bit, which are then dithered back down. Does it also result in a greater dynamic range?
I was told by a sound engineer that, when mixing, it is not a good practice to have all the channel volume faders way up and to have the master fader down, and that this applies both to analogue and digital consoles. Is this true?
I did a recording session recently using a mixture of dynamic and condenser mics, and realised my desk does not have switchable phantom power for each channel — they're either all on or all off. Luckily, I had some external channel strips which I ran the condensers through, but is it safe to apply phantom power to dynamic mics?
