Smallest Pre-amp with 48v Phantom Power
« on: January 27, 2011, 12:52:09 PM »
I'm looking for a good quality pre-amp that will supply 48v phantom power.  Right now the Aerco MP-2 is the front-runner, but I'd prefer something that is more similar in size and closer in price to the Naiant Tinybox.  Any suggestions?  Can the Tinybox be custom ordered with 48v rather than 12v phantom power?  Thanks.

the tinybox does not do 48, but the littlebox can
prob roughly the same size as aerco but much less in cost, custom made for you, ships faster
Mics - AKG ck61/ck63 (c480b & Naiant actives), SP-BMC-2
XLR Cables - Silver Path w/Darktrain stubbies
Interconnect Cables - Dogstar (XLR), Darktrain (RCA > 1/8) (1/8 > 1/8), and Kind Kables (1/8f > 1/4)
Preamps - Naiant Littlebox & Tinybox
Recorders - PCM-M10 & DR-60D

In the way of small preamps, there are (including historical and current models) the Aerco, the Beyer MV100, Sonosax sxm2, EAA/Aeta PSP2, Aeta PSP3, Sound Devices MP2 and MixPre, and the Naiant littlebox.

I'm sure this list isn't all of them, just some I can think of off the top of my head.  I don't think any are smaller than the Aerco MP2 though.  Beyond that, they're all probably pretty much in the same ballpark for size.

The tinybox does not do 48v phantom, and can't be configured to since the blocking capacitors needed to block the 48v DC are too large to fit in the tinybox case.  I'd imagine this would be the case for any 48v preamp attempting to be that small, so I'd doubt there are any 48v preamps the size of the tinybox out there.

Not to re-open your mic question, but the smallest solutions are probably to use the tinybox with schoeps caps and schoeps CMR cables (and no bodies), or similarly to use the Beyer ck930 caps and cables with a custom made tinybox (again with no bodies). There are some threads with pictures on these options.

Short of that, getting a pair of mics that can run on 12v phantom like the Milab vm44-link and pairing them with a tinybox also yields a pretty small solution.

I'm curious if there are any 48v phantom preamps out there smaller than the Aerco for use with any 48v mics (thus not including the schoeps nbox solution).  I can't recall any options though smaller than than those on the list above.

Although it's not just a recorder - the Sonosax mini-r82 is a little bigger then a Korg MR-1, runs off 4 AA's and not only provides 48V but also is a 8 track recorder.

Bingo. I almost listed an abreviated form, but realized that while I think the sax is sort of small when I hold it, it's not as small as the aerco, and if size is important, it's not going to beat the mp-2. The littlebox gets a good mention because it's comparatively cheap so a small hit on space may be worth it.

Although it's not just a recorder - the Sonosax mini-r82 is a little bigger then a Korg MR-1, runs off 4 AA's and not only provides 48V but also is a 8 track recorder.

the r82 will fit the bill if price isn't a problem and you're willing to ditch your recorder as well.  ;D

At least you'd still have a sweet Submariner on your wrist.   :D

I put the dimensions of gear mentioned into a spreadsheet.
Turns out the Aerco is one of the the smallest pre, at 18 cu.inch, even compared to all-in-one recorders.
The only P48 device smaller than that is the Denecke PS-2 (15 cu.in), but it doesn't come with any gain.

Other contenders and their cubic footprint:
Sonosax MiniR82   77 16.4
Aerco MP-2           16 18
Core Sound Mic2496  23
Zoom H4n           23
Littlebox                   25
Tascam DR-100   27
PSP 3                       27
MV100                     30
SX-M2                      30
Mixpre                     35
SD MP-2                   35
USBPre2                   47
Echo Audiofire 4   49
Graham-Patten DMic-20/24  56
Wendt X2            58

(edited, sorry got some figures wrong)

Sonosax MiniR82   77


I don't think it's that big - I actual have one (temporarily) right now and it's much smaller than I thought - maybe an optical illusion or something (a swiss mind game).


I'll post some comparison photos soon but it looks to be about the size of a sony M1.

Yeah, good point.  From what I've seen, the miniR82 is 4.75" x 3.15" x 1.1", putting it at 16.4 cubic inches.  Considering it includes the recorder as well, definitely the smallest solution.

guess i don't understand how to come up with cubic inch
the lb is .2"x.1x.7 inch bigger then the aerco
how does that come out to 9 cubic inch bigger?
isn't a cubic inch equal to a cube thats sides are all 1"

Todd is right, I goofed on the MiniR82 dimensions.

Will, the cubic footprint is simply the W x D x H multiplied.
As an example, Littlebox specs are:
"Case size, standard: 4.7" x 3.1" x 1.7" (120mm x 78mm x 43mm)"

4.7 x 3.1 x 1.7 = 24.769
