I've read the manual and kept up with the threads. Here are some M-audio questions that I haven't found answers to. The specific gain levels of the pre-amp stage seem to be missing from the manual.
1. In what increment can you adjust the input gain?
2. Is the input gain implemented via a traditional analog level increase or is it done digitally?
3. How many dB are added at each L, M, H setting?
4. Are any auto-level control or clip limiting functions planned in the future?
From the manual (page 6), this suggests that the 1/8 input does most of what the TRS input does (other than phantom):
17. L/M/H Switch: Sets the operating mode of the 1/4" TRS and 1/8" inputs. Use the `L' position for line-level devices. The `M' position
should be used when recording from microphones. The `H' position uses a higher gain stage on the 1/4" TRS inputs, which can
help when recording quiet signals or using microphones with low output levels. The `H' position does not boost the input gain of
the 1/8" input.
I run my 4061's with an SP 9 volt battery box.. I need to decide whether they're going into the 1/8" input or the 1/4 input and make the appropriate cable..
What I'm guessing: L, M and H are analog gain stages. But is the fine-tuning after that digital or analog? The menu has an optional 27dB DIGITAL boost in addition to what is available from the LMH settings (page
. That is the only instance where they mention DIGITAL gain, so I'd hope it is otherwise analog.
Every AT8XX, DPA 406X, etc MT taper would like to skip running an external battery box. I remember Doug mentioning that the dpa bbox is actually 6 volts. Anyone know? It would be nice to run it straight into the MT, either with the existing 5volt power or with a mod to provide something more optimal. That'd be a good mod for someone to work on.
Who will be the first ts.com member to run 4061's into this thing, with and without bbox?
