I'm in a small church. We are purchasing an upright acoustic piano. It will probably be loud enough (probably too loud) so I don't need ampification. But I do need to make digital recordings. I would like to get a mic to isolate just the piano to put it in a mix. It will go from the mic to a soundboard then to a computer. Then to a CD. Any suggestions of what mic to use? The simpler the better. I realize that more than 1 mic is best, but I would like to get away with just one.
If you're looking for isolation & a fairly open-field sound, then maybe a boundary mic would help.
Experiment with mounting positions - on, in, or on the wall behind the piano.
If the setting/surroundings call for a small cardioid, how about a DPA 4099 on goose-necks, as shown in the review video at
With only one mic up close (for isolation), it may be beneficial that 4099 has a pretty even off axis response, so the sound coming in to the side of the mic also sounds fine, only at a lower level. Thus it is possible to place the mic around one end and aim it at the far end, not getting too uneven level from the different part of the piano.
At least such a very directive (narrow pick-up pattern) and a placement off to one side, aiming along the instrument, may be acceptable at a shorter distance than a wide cardioid over the instrument centre.
I have not tried it. It may not work as well as it does on acoustic guitars.
