I would go for the AB omnis with a semicoincident pair in the middle to capture the sound of the entire group. But I agree with you, maybe I should consider AB+spots for this hall (small, with place for around 150 persons). Here comes the problem... How can I put five spots in so a small group with the instrumentists placed close together without coming into a phase and leakage nightmare? The two bass sounding instruments, cello and double bass are placed together too.
BTW, I've attached a sample of a concert I've recorded some months ago. It's an amateur sax quartet. I used two omnis (Oktava MK012) in AB at 45 cm, placed 5-6 feet away from the musicians and 4-5 feet above his heads, plus only two spots (AKG C391), one for the soprano and alto saxes and another one for the tenor and bariton saxes. As said above, I've learned this technique from a radio technician, but I'm not convinced of the effect of the spots in the final stereo image. The recording is a bit dry, the hall was very dry and I've added no reverb or post-processing effects to this sample, I'd like to know your opinion, possible mistakes you see, how could I have made it sound better... bond.mp3
