h4n Pro Mid-Side Settings

Post by AdrianW » Mon Mar 19, 2018 6:46 pm

I typically do mid-side recordings on my DAW, manually or with a mid-side decoder and would like to do the same with the Zoom h4n Pro. I've had the Zoom for about a week and I've gone through the manual many times but haven't had much luck.

1. I'm using two mics into the XLR inputs, one cardiod, one figure-8.

2. Matrix is on, side and mid levels set, source set to inputs, mode is 4-channel.

3. Channel settings are made, in my case left=mid, right =side.

Recording seems to work and I can monitor in decoded mid-side BUT the two built in mics are still active which throws things off. I'd like to be able to record mid-side with just the input mics and save the result as stereo file. Is this possible? Am I missing a setting? Thanks.

Off-hand... Do not use 4-channel mode! See manual page 021. 4-channel mode create one stereo file from the built-ins, and a second stereo file for input 1&2.

Use regular Stereo mode, select Input 1&2 (ie; do not activate the built-ins).

Note that using the H4n matrixing function, you will be recording a stereo file with the matrixed (mid/side level ratio) -- you will not be able to adjust mid/side level later in a DAW. If you leave matrix OFF, you will record pure mid and side channels which can be manipulated later to adjust the apparent image width -- but monitoring will be terrible as one ear will only get the mid, and the other will hear the side signal.

Thanks. That's what I needed to know. I was confused by the M/S instructions in the manual under the SOURCE section where it said "Set the input used (only in 4CH mode)." which seemed wrong to me. All good now. When using the M/S Matrix and recording in stereo I assume it's important to have the mid and side mics routed to the correct left/right channel. I suppose they can be flipped but it seems it might make sense to always use mid to INPUT 1 and side INPUT 2.

Manual, page 74, last screen shot -- specifying which channel has mid vs side... And yeah -- that 4-ch mode comment seems rather useless -- since you can't really use the built-ins for mid/side, why not just default to input 1&2 if matrixing is enabled.
