Thanks so much for all the help everyone. Sorry I didn’t respond sooner. (Don’t hate me) I had to catch flight to Kona Hawaii, that afternoon and ran out of time. We ended up just having him play the original english version on a laptop in the booth, and recorded to a zoom through the xlr wall connection. That way he could see it and hear it in his headset while recording. I will try to mount a monitor inside the booth and connect it as a second screen to the laptop outside.
I find that it is nice for artists to be able to see and hear the original source material even if they are just doing a language VO. They seem to match the original feeling of the native speaker that way.
Thanks again.
