Splitting a mic preamp output

I'd like to split the output from my mic preamp during tracking so I can route the signal both the the AD converter for recording and to the monitor controller for latency-free monitoring. Is it okay just make a TRS Y cable for the patchbay to route the signal to two places, or would this cause problems.

As long as your converter and monitor controller don't have input transformers, you can use a Y-cable for line level with no issues.

I also asked this question not so long ago. Apparantly its also ok to 'mult' from the patchbay and this will probably be the way I do it at my new studio (if it ever gets finished).

I found this '4 in : 8 out XLR splitter' on ebay recently also, which caught my eye.

What's the problem with input transformers? I mult to transformer coupled inputs on a regular basis and haven't seen any problems. Fill us in.

I asked a few people much smarter than me this question.......and the overwhelming response was use a Y-cable thumbsup

Input transformers can be 600 Ohm impedance - some outputs will have issues with driving 300 ohms.

Yup, even without splitting 600 ohms a lot of gear can have problems driving a 600 ohn load as it is. A consumer CD player trying to push a 600 ohm circuit can sound pretty ugly.
An impedence issue. yeah, you definitly gotta stay within the range that the driver can "push", but that isn't an inherent transformer only scenario.
But point taken.
