So this Monday I get to record the local choir I sing in at the small church where we rehearse. This is my first attempt at recording a choir and I still consider myself quite a novice when it comes to recording in general. The mics I have available are a pair of Nuemann Km140's, a pair a Cascade fatheads, an Advanced Audio CM47se and an re20 (although I think I won't use this one). I know this selection wouldn't be anyone's first choice but it is all I have at the moment. The Preamp I have is a UA 4-710d so I wanted to use only up to 4 mics.
The dilemma is either using the 2 Km140's as an ORTF just behind the conductor or a spaced pair in front of the choir at about 1/3 and 2/3 width apart. I was then thinking of using the cm47se in omni as an ambience mic and a fathead as a spot mic for the piano? My idea was to try get the best possible sound out of the two Km140's and then blend the other two spot mics to taste. This plan is based on no experience so any help or suggestion will be much appreciated.
The church isn't the best sounding church either unfortunately, sounds very dry and when I sing in the choir myself I find it hard to hear all the other parts clearly.
