Hi there,
I'm new to this forum, found your postings very interesting, and would like
to add some observations I made using my stock 671.
It writes to a 4gb Lexar 80X, which gets freshly formatted before each session.
Usually, I run it at 24/96 with a stereo pair of DPA 4006. Both phantom power and display
are on all the time. With both DPA and Marantz attenuators off, volume is usually set
to 2-3 in my recordings.
The rechargeable battery provided by Marantz went down after less than 60 min
a couple of times. I don't think it was due to a battery fault, or because of a problem
with the sledge. It seems to me that the built-in charging circuit is not reliable. Often the red light goes
out after a very short charging time. But when the recorder is switched on and off, the red
light comes on again, and charging continues for another hour or so.
To be really on the safe side, I took a motorcycle battery and connected it to the unit using the
sledge as a plug. Now power is stable, but clipping still occurs.
Just as some of you described it, it happens at -4/-3dB. Never at home, when recording single
instruments or voices, but frequently with complex signals from orchestras and choirs.
Perhaps the meter is just not good enough. Or the built-in pres are to blame. I would be very grateful
for any ideas (since I'm in Germany, getting Oade mods is not an option).
I'm planning to get a Mini-MP and link it to the 671s line input. If this does not help, I may
take a look at the MR-1000.
Cheers,
