Topic: Can the Sound Devices 722 do M/S Mid-Side decoding?

Thanks.

Dunno, I'll let someone who owns one respond directly.  But...even if it doesn't, run M/S anyway.  You're better off decoding in post-production, at which time you'll have complete control over the mixing process.  That way you can try different mixes and see which you prefer.  No point in doing it on the fly, IMO.

Thanks.

yes
  on the input or on headphones only

YES - ran mine M/S a few times..  with updated firmware you can work it in much the same way as a VMS...

My favorite was to run the mics in M/S config and record the channels independantly of each other and then use the M/S mixing protocal in Soundforge 8.0 and play with it until I got it the way I liked it...  if you do that DO NOT set up in the menu as M/S where left knob controls levels and RT controls width..  Run as normal Track A and B...

I believe you can monitor while you record as a M/S Mix via headphones..but not 100% here.

YES - ran mine M/S a few times..

When you did that, did you run so that the M and the S tracks have the same peak levels?   If so, did you have to set the gain range of the S channel to the higher setting?

I ask because the one time I have been directly involved with MS, it appeared that the S channel required a lot more gain than the M channel.  I'm hoping to try MS with my 722 sometime this year.

I haven't run M/S on a 722, but in the times I have run that config, the S channel needs significantly more gain than the M channel in order to get equal levels.

[CQBert]

I ran them so they were peaking nearly identically...  in Soundforge you are able to control the % of mix of the M and S channels.

After the mix of the two I would simply normalize it and then burn audio.

Hope this helps.

Anytime - good luck...

it would be a great comparison tool (for the 744!)

run the straight mid-side into two channels, and then output it back into the 'on-the-fly' for a field test of different widths.

I haven't run M/S on a 722, but in the times I have run that config, the S channel needs significantly more gain than the M channel in order to get equal levels.

why do you want to get equal levels when running m/s?  I'm not saying you shouldn't, but what's the reasoning?  I typically run equal gain and the levels are very unbalanced, but in post, I still find myself mixing more M most of the time.  If I run equal levels, I mix very little S and typically have to do a gain reduction to keep from going over.
