I agree with Todd, and not only because I run virtually the same rig.  There really aren't any 24 bit A/D converters that are small and portable except for something like the Mytek, which may be overkill.  At first, I was suspicious of the A/D on the D50, given the fact that their portable onboard DAT A/D converters were terrible.  I really like how the D50 sounds however, so Sony finally got it right, IMO.

Does the 148 have a 1/8" output?  I haven't had any problems with going 1/8" > 1/8" on my PSP-2 > D50 and it sounds fine.  If not, could you go XLR ? 1/8"?  While it may not seem secure and appear chintzy, in practice, the 1/8" input for the portable devices actually works well.

Bottom line, I would consider the Sony D50 or the Marantz 661 if you are trying to keep the rig to a reasonable size and with good quality.  When I was making this decision, I also looked at the Sound Devices machines and judged their onboard preamps to be total crap.  All of these units have good quality A/D converters, however, so I would recommend running one for a little while and seeing how it sounds before investing in a Mytek or something like that.

2 people in one thread that don't like the sd box
i agree though the sound doesn't do it for me UNLESS its with dpa
dpa are the only mic i like ran directly into the sd7xx

anyway i also agree the sd7xx is a "waste" if you are using it as a bit bucket

i find the fr2le and 661 great for the cost too

yeah i didn't post anything helpful -t  :P

you get noise running the 148 into either the xlr of the fostex or the 661. You CAN run 1/4 inch into the fostex, according to Doug.

yeah, the 1/4" TRS jacks are unbalanced and should be ok if you can get the appropriate cables or adaptors. If you get lucky and find the PSP2, then I agree with Todd and strip down the rig a bit. I'm trying not to fluff the fostex, but I think it would work for what your trying to do with a budget that isn't a doozy.

If you get even more lucky the batteries won't melt in that psp2!  sound great till the acid runs out on your gear.

who let the UK fan in?  ;D

I don't have a huge issue with running xlr>1/8, but the 1/8 is stock, and Doug isn't modding it yet.

the Mytek looks good, and no screwdriver. :P Pretty much decided on the 661. that way, I can appear to be modern, Todd, but I'll actaully be running 16/48 from the modsbm1 to the 661, old school style until I can pick up a Mytek. Tape like it's 1999.  ;D

Hey, Marc...

Not sure if you've ever looked at this littlebox project or the comments in and around this thread, but if you can wait and or want to suggest a development path to the builder, I'm thinking he might be able to fit your needs for a small package.  Might even consider a designing a dedicated unit that will retire the SBM-1.  Mine, BTW, is starting to heat up batteries like crazy.  Doug seems to think that it's the DC-DC converter going bad.

Mid 60's today, you should come "home" for a visit. ;D

Not a problem running it with an external battery.  Actually, I'll leave it to a new thread with pictures sometime in the near future, but I just did an easy mod to my PSP2 to fix that problem.  Got a brand new battery sled since the old one was starting to crack, took out the internal spring battery connectors (since I think it was those connectors making an intermittent connection that was causing the problem), took a dremel tool to cut a notch right where the battery pack goes in to allow a small cable to pass, and then wired up a short ~3" coaxial connector/cable onto the new battery cage.  Put the battery cage (that only has the coaxial dc output on it) inside the PSP2, which now has no internal power connection so it won't screw up, extend the short cable outside the psp2 through the notch that was cut, and then plug in the internal battery pack to the external battery connector.  Keeps it low profile, no actual "external" battery pack, but the internal pack now connects through the robust external battery connection instead of those crappy internal spring connections that are nothing but trouble.

Anyway, pics and a new thread on that one soon. [/hijack]

I have never had a problem with batteries leaking or anything of the sort in my PSP-2 and I use AA batteries exclusively.

good to hear from you, O-Dog, and yeah, I'm long overdue for a trip up North. I figure at some point my modsbm1 will crap out too, it's 8 years old, but has served like a champ. Thanks for the info, will definitely check out the thread. ;D

How does the mic2496 sound? That's a small 24 bit adc. I know WiFiJeff here has it or used it. He was going to use the Mic2496 V2 with his D50 at one point but don't know if he ever checked how it sounded compared to his D50 A/D.

Same here on the PSP-2. Also You can flip the batt cage around when not in use, so the contacts don't touch.

You still trying to keep the weight down for your back, Marc?

Ditch the brick and go find yourself another freedom pre.  EAA>Sony D50 is an amazingly small setup, and the D50 line in sounds very good.
