Title: 24 Bit Recorder Questions
Post by: Boedi-taper on August 05, 2008, 05:19:50 AM
Hey Guys!
Longtime Dat taper looking a possibly switching to a 24 bit recorder.Here's my questions(Thanks for your patience):
Question #1: Do any 24 bit recorders in the $300-400 Range have a right AND left channel 1/4" mic input?(To handle my Nakamichi 300 mics).Or:
2) Do any 24 bit recorders have a Digital input that a Sony SBM-1 can plug into? For any that don't know,the Sony SBM-1 Have  2 1/4" mic inputs that I use my Nak 300 mics for.The SBM-1 input plugs into the Dat deck.
3) I know that some models of 24 bit recorders have a single 1/8" jack for mic input,however,the two 1/4" Jacks for each mic would be much sturdier and stable.
4) Do any or all of the 24 bit recorders in the above price range have mic attenuators for an outside mic source?

Thanks for any responses!! Peace!!!

Take a look at the M-Audio Microtrack II.  Price about $250 through an online merchant, and less than $240 on eBay.

The MT2 1/4 inch inputs are noisy if you're using an unbalanced mic cable, but work OK with a balanced cable.  See guysonic's note with noise graphs here:
http://taperssection.com/index.php/topic,88437.msg1286241.html#msg1286241

The added noise is described as like a "sprinkler" or a "helicopter"

gt6john found one solution:
"I was experimenting with the 1/4 unbalanced noise thing and discovered that if the two wires from the unbalanced source are connected to the tip and ring with nothing on the sleeve it works great, no weird noise and very clean recording."

DPA tested the MT2 with its mics and found a workaround.  dactylus reported:
"The DPA testing results were as follows:  Using the unbalanced 1/4" TRS inputs a "sprinkler noise free" recording could be produced when turning the gain all the way down on the MT and doing all of the gain adjustment with the dpa mma6000 amplifier."

Guysonic found the MT2 has a lot of headroom on the mic input
"MT2 minijack mic maximum ~ -2.4dBu (the ZOOM H2 maximum LINE input!) compared to MT1 -13.3dBu, so MT2 has slightly over 10dBu MORE headroom than MT1; this is a significant improvement."

The SBM1 is a 16-bit device (outputs 16 bits), so there is no point in using a 24bit recorder if you plan on continuing to use the SBM1.

That said, I think most of the modern recorders are 24bit now.   And again, most of these will have a mic attenuation circuit, but few have dual 1/4" inputs, the MT is the only one I can think of.  I'd highly recommend the Sony D50 which I have and love.  It's outside of your price range new, but you can get a used one for that price.  Single 1/8" input and optical digital in only though.

You might want to contact Busman Audio (see the Retail Section for his posts) and see if he can mod your Nak 300's to use a different termination -- perhaps 1/8" as it is more common on recorders.

ZOOM H4 (under $400) records at 24 bit and has combo XLR and 1/4" separate right and left channel mic inputs, as well as phantom power.

Boedi, do you use the SBM-1 to power your Naks?
Are the Naks stock or modded? How is the cabling done? XLR to 1/4" TS or 1/4" TRS
Like Todd said, the SBM-1 does no more than 20bit, so in case you're going the 24bit way, you also need to figure out another way to power the mics...

You didn't say anything about stealthability, but if you don't mind bulkier recorders you could run the Naks with XLR in to a PMD671. If you're lucky, they can be bought used within your budget.

Or the FR2-LE, thats close pricewise (Can be had for $450 shipped) if you need XLR (w/ P48) & 1/4", but can live without 1/8". It fails the stealth and digi-in tests. If I were going to stay with an outboard AD (or at least use one more then half the time), the MT2 would probably get my vote cause of the coax in. When I went 16 > 24, I ultimately decided between the Fostex and the MT2 based on that the outboard functions and whether I would use an outboard AD/pre or go all-in-one.

TRS> FR2-LE is a good option.  If you have it modded you'll essentially eliminate the need for the SMB1 and have a good all-in-one option without getting into extra adaptors or anything.
