Quote Tom Ballinger:
Im recording a choir and organ next week and have no idea how im gunna mic it up. the organ is directly to the right of the choir.
i have access to rode NT2a (x2), Neumann TLM 103, Soundfield Microphone and a pair of SEa1.
the choir is small mostly women with one man singing bass they are very quiet compared to the organ as there is only about 12 of them
I'm worried about this idea that the choir is "very quiet compared to the organ". The organ is a musical instrument, hopefully controlled by an experienced musician. As well as playing the right notes, his job is to play at an appropriate volume so as to accompany the choir rather than overwhelm it. I'm sure he is competent to do this.
So let the musicians take care of the music! YOUR job is not to correct the balance, but to find mic positions which capture it well.
How many tracks do you have available to record to? Is this a set-up purely for the recording, or are you capturing an occasion? Will you be able to use up a control room where you can set up proper monitoring?
