If you run an external preamp, will you be able to bypass the preamps?

superb question....I wanna know also.

Highly unlikely considering the earlier models design.

so it looks like you can run SPDIF line in for Ch 1/2. if that is the case then it would bypass the internal pres. So then you would only be dealing with channels 3/4.

Correct assuming that you have a pre that is a pre and a/d combo like the V3 or AD1k.   The only way you bypass the pres  inthe R44 is if you run digital in.  If you run out of just a ore and are using the R44 a/d section then you are still getting some of the pres of the R44.

A couple of points I noticed from playing around the last few days without ts.com

01. Uses a Transcend Type 6 16g SDHC card with no problem.
- Got one from newegg.com for less than $75 delivered.

02. Gain is controlled by a Combo Level Knob:
02a. The sensitivity dial (outside of the knob) is set in 11 incremental steps; +4, -2, -8, -14, -20, -26, -32, -38, -44, -50 and -56 dbu.
02b. The level dial (inside of the knob) is a continual
- Set each channels independent sensitivity, then fine tune it with the channel's level dial. Its worked good so far.

Boa, how do the stock pre's sound?

They sound adequate so far

Another size comparison. About the same height and depth as a PMD-671 and maybe a little more then a third less the width.

I'm about to start doing some run time test (both 16/44 and 24/44). I'm going to do:

Beyer MC930 > R-44 testing AA 2500mAh Rechargeables, AA Alkalines and, 9v ION 5400mAh battery
Beyer MC930 > V3 > R-44 (digi-in) testing AA 2500mAh Rechargeables, AA Alkalines and, 9v ION 5400mAh battery

Anyone want me to test anything else?

All good tests there.
The ones I've bolded are the ones I was wondering about.  Specs state 9-18vdc (i believe) for the R-44 so I'm wondering if the 9v DVD LiIons will work OK if the voltage drops a bit in use.  If not I suppose I could run 2 DVD batts in series. I have two that I alternate for the V3 currently, but could wire them to provide the V3 with 9v and the R-44 with 18v.

Anyone want me to test anything else?

Yes, please, thank you.  Take a digital source with a couple of small tracks and run a spdif to your other bit bucket listed above.  (Marantz?)  Record a couple of tracks.  Then hook your R-44 up and run the same few tracks.  Then dump them to your PC and do a bit comparison using EAC's "Compare Wavs" feature to check bit accuracy.  If it is off it will tell you how many samples the recording is off by.

I am less worried about battery life than I am about it re-sampling the digi-input.

Will this be accurate if the tracks are even slightly different in length?

[kskreider]

No it won't be accurate if they are different lengths.  Get in a wave editor and chop them to exact start and stop times.

Well I don't think AA will work in the field. I'm just pass an hour and the batteries are almost done.

Under what conditions?  Lights on, phantom on, sampling rate, etc etc?

I ended up getting about 2:30. Phantom On, LCD on lowest brightness, recording 24/44 and I was using Alkalines. I'll try Digital in next.

The good news is it saved the file before shutting down.

Is that 2 1/2 hours with phantom on all 4 or just 2 phantom, 2 line in?
I bought some rechargeables for mine to try, but its not here yet to try.
