Spliting a vocal mic into 2 channels on the same desk?
« on: June 28, 2011, 05:35:32 pm »

 I run a compressor on each vocal, unfortunately the aux sends are post insert. I want to send the monitor mix uncompressed vocals.

 So can I make up a Y splitter, 1 xcrf to 2 xcrm.  Take one and put it in channel 1 with a compressor, take the other and put it in another channel, with no compression.  The channel with no comp. will be used for aux sending only.

 This will work, but will my simple splitter work? or will there be a gain ( loss ) problem splitting it this way?

Thanks
Al

It's no problem using XLR Y splits for mics. It's done all the time. There are no appreciable losses doing this.

You approximately double the loss from the typical bridging input termination from about -0.8dB of level to -1.5 dB or so,,, not a big deal and pretty commonly done when there's a good reason. 

You could also take a direct out from the dry channel, send it to the comp and return that into another line input. You still burn two channels but don't have completely independent gain trims, and perhaps faders.

Splitting the mic at the front end gives you the most control flexibility for a modest signal level penalty.

Also, if one is switching between house desks one might run into direct outs that are configured all over the place, so "going wye" leaves the mixerperson more confident of what's going to affect what.

I have frequently used this work around when doing monitors from FOH. On more than one occasion it was easiest to put the split right at the stage box. I don't think any modern mic I have ever used will have a problem driving two channels at reasonable levels.

Nice idea!!!!!

I used the split on vocals over the weekend, didn't tell the singers.  I asked them at the end of the night how was the mon. mix.  They said they never heard themselves better.  I sent the bass player a compressed vocal mix as he uses in ears.  2 of the singers can get into 10 db of gain reduction at times, so I don't want that uncompressed signal in his in ears.
 With all honesty, the keyboard player with a uncompressed vocal in his mon. stopped screaming, or pushing himself on certain songs,,, it was great!!!!!
 The womon singer uses a wireless and is out front more then on stage, so she uses the mains as monitors.  When I asked the rest of the band how she sounded in the wedges, they said never better.

I should of done this a long time ago.
