I finally got around to experimenting with my DR-60D over the last few days. Up to this point I've been apprehensive to take it into the field since I've been so used to the M10 over the years. Here's how it was setup:
AKG CK63.naiant.pfa > DR-60D (mic in, phantom on), Channels 1 & 2
and
MG21.nBob.pfa > Aerco MP-2 (1/8" out) > DR-60D (1/8" in), Channels 3 & 4
Everything was running off my Tekkeon-style battery (Aerco at 9v, DR-60D USB out at 5v). The DR-60D was set to record two stereo files at 24 bit, 48kHz. I recorded for about 2 hours and the battery level fell no more than one bar, out of seven. Now, the Aerco barely sips any gas at all so I wasn't expecting it to affect the battery life much, but expected the Tascam take the bulk. I'll have to do another test for longer, but this definitely seems promising, and I'm getting much more comfortable with the unit.
Are you guys getting similar results? Any issues with overloading the inputs?
