I am currently working on a documentary film. I shot all the interview with my XL-H1 and a Rode NT-3 microphone. The sound quality is great.

However, for my next projects, I will be shooting both on-video and off-video interviews. The off-video interviews will be audio-only and I do not intent to use my XL-H1 to record the audio. So I am looking for a good digital field recorder.

However, I am not sure what I will need. I am planning to buy a Audio Technica ATW-1821 wireless system next month. So what I would like to do is the following: get the audio line out of the ATW receiver and feed it to a digital field recorder. Monitor it from that field recorder.

I found this great site:
Portable Recorder Reviews (http://www.wingfieldaudio.com/portable-recorder-reviews.html)

The models I consider are:

Olympus LS-11
Sony PCM-D50
Zoom H4n
Marantz PMD661

The Zoom H4n and Marantz both have two XLR inputs. My question is: do I need them? I guess I will if I want to use my Rode NT-3 (or I could use a battery and XLR -> 3.5 adapter cable). How good are the fixed microphones on the LS-11 and PCM-D50? If I place those recorders on the table between myself (interviewer) and the interviewee, will I get a clean, high quality sound file that I can use in my project (edit under video or photos)?

I also thought about using my MacBook Pro and the USB -> XLR adapter I read about on these forums. However, that is a bulky solution that I cannot use outside so I think using a portable field recorder is a more versatile solution.

All feedback/input is highly appreciated.

If you want to match the great audio quality of your existing footage, I'd suggest that you continue to use the same microphones and microphone techniques that got you this far. At a minimum, that would mean getting a recorder that gives you access to the world of pro audio, meaning it's gotta' have xlr inputs.

As I'm sure you've read, there's quite a bit of user info on the H4n and 661 in this forum. I'm pretty happy with my H4n.

Either would give you two xlr inputs to use with your NT3, AT1800 series, other pro microphones - this and your recording techniques will be important.

PS: And, monitor with headphones! Otherwise, it's impossible to know what you're getting.

How about Sound Devices MixPre + Sony PCM-M10 or PCM-D50?

Why not continue to use your current setup?

Because it makes no sense to use my camera and dv tapes to record audio-only. I am going to make a few audio-only documentaries (like those of the BBC World Service), and do not want to drag my Canon XL-H1 with me for audio-recording only.

If it aint broke , dont fix it, you're happy with your sound so save your money and keep doing what your doing with your current set up

Your going to have to lug some equipment with you anyway and you wont get the same results from a Zoom as you do from a camera IMHO

Who knows maybe one of the interviews will give you an idea for a video documenatry and you wont have to reshoot

My preference would be to use a sound recorder for an audio-only interview. If the equipment is less visible the interviewee is more likely to relax.
A sound recorder with controls that are easy to use (not fiddly), a good limiter and level indicators that are easy to read will let you concentrate on the interview rather than technical stuff.
You can't hide behind a camera in an audio interview and you want to maintain eye contact as much as possible.

That is also how I think about it Richard.

I still have to decide which recorder to buy though.

I don't know how it compares with the recorders on your list but you might want to look at the Fostex FR2LE also.

I have the Zoom H4n, but unless your mic has a very high output that recorder works better with balanced line-level input and a separate mixer or preamp. I have used my NT-3 mics with my older Zoom H4 and it was adequate but had no more room to boost with a quiet subject. I haven't tried my NT-3's with my newer Zoom.
If I was doing important audio-only interviews in a fixed location, I'd be using a mixer or preamp anyway for better control.
However if you want the minimum-sized kit for field use, getting a recorder that has good preamps with your specific mics is important.

I have a JuicedLink CX471 that I have been wanting to pair up with a Zoom H4n. Has anyone tried this combo?
