Hi Mike--
Smart to test for this if you are really thinking of getting by with
the noisier mics. Lots of factors to take into consideration aren't
there?
Maybe its a part of our job as a community to help the manufacturers
understand that they need to spend more time figuring out how to
package convenience and high performance and reliability.
We know from Hi-MD's that quiet mic pres are not expensive to add,
yet since 2004(?), there are only four, lower cost, recorders that
can match Hi-MD and they're all much bigger than Hi-MD's: Fostex
FR-2LE, SONY PCM-D50, Marantz PMD661 and Marantz PMD671. Several
manufacturers have incorporated a phantom power supply in a small
package too,.. but none have put all the right ingredients together.
I really don't mind carrying a 744T and a 8 lb. mic rig up the
mountain; its the 45 lb. car battery required for several, 12+ hour
recordings that hurts. On the other hand, we all look like lazy
whiners if seen by recordists a mere 20 years ago. Rob D.
