Caution: an open mic input doesn't represent the recorder's
self-noise. It's usually considerably more noisy, and noisy in a
different flavor, than the input when properly terminated.

To hear a preamp's noise, terminate the input with a 150-ohm resistor
(for typical dynamic) or 2k ohms (for PIP electret capsules). Best to
make up a dummy XLR so the resistor is shielded, too.

Mic noise is significant, as taught by Rob and Klas. Quiet mics are a
must for quiet soundscapes.
