Did it just say Aerco or did it indicate which model?  There were a couple differnt models.  My Aerco is a DB-2 which I think predates the MP2 that everyone else seems to use.

so how do these little guys sound when compared to the psp-2 and 148? 

Did it just say Aerco or did it indicate which model? There were a couple differnt models. My Aerco is a DB-2 which I think predates the MP2 that everyone else seems to use.

is there a difference between the db-2 and mp-2 ?

i, of course, want one.  >:D

You little slut.   >:D

My Aerco (mp2, I presume) does not note a model number on the unit, and looks like the first pic posted, not the db2.

I believe the maker of the Aerco will actually still make a custom one to buyer's specs.  They use Reichenbach transformers, whereas the M148 uses Jensen transformers.  The powering/phantom supply of the Aerco (3x9volt) will create a large sound difference from the m148, which has a more pure form of powering for sonic reasons.

these aerco units, the psp-2 and the oade m148 are the only tranformer based pre's available right? the big advantage of the m148 is the powering scheme right? i realize the m148 is the pre to get, and i have run a psp-2 and really like the sound of one. how does the aerco measure up to the psp-2?
 
also, how does one change the batteries in the aerco? has anyone found a workaround to the pop that happens when the gain is changed?
thanks goose.............. (+)

I thought the SD MP2 was transformer based as well (sounds like it), but that may not be correct. 

Yes, the m148 has a power scheme that avoids noise, and is one of its strong selling points.  I will stop there, as it answers your question (in my mind at least!).

I've cannot comment on the Aerco/PSP2 comparison.

To change the batteries in the Aerco, you unscrew 4 screws that hold the top lid on, and place the 9 volts inside the box and put the lid back on.  The units also run on 7-20 volts DC external power.  I'm not sure if there are any noticeable differences in sound when run from internals or external power.

I feel confident in saying that there is no way to get around the click when changing gain.  The good news for that is that the steps are 10db (on mine at least) from 0 to 50db, and you will likely use the same setting at a club for most shows there.  You can get to know that "X" (venue) needs 20db, and "Y" needs 30db.  Shouldn't be too much switching between settings in reality.

First off, AERCO is: Acme Electronic Robot Company.  One man operation, guy's name is Jerry Chamkis.  Google brings up loads of funky stuff he's into (catching gamma rays from outer space, and running them through a synthsizer to produce weird ass sounds).  I don't know if he still will make them, but he recently serviced mine and told me as long as he's alive, he'll keep them going for us.

I'm pretty sure each one is a custom unit, because I also have an MP2 (verified by the label on the inside of the unit) and it's a bit different from what Goose said his is.  Mine looks a little bit like the first pic. but has XLR (M) outputs, instead of RCA's.  Mine has a stepped gain as follows: 26db, 28db, 30db, 40db, 50db, 60db (or so the label on the top says).  Mine also has a 4-pin XLR already rigged into it for external power.  I only use the internal 9V option when stealthing, as they are a BITCH to get in and out.

FWIW,  I've been told, mine at least, has Jensen transformers and futhermore  I've been told that Jensen and Reichenbach are one in the same. 

All I know is is sounds damn fine with my 4022's, it did sound fine with my old Earthworks as well.

Tim, seein' how you're a member of Team Upstate, if you want to borrow mine for a bit, I can send it out.  PM me for details...

Fwiw, SD mp-2 uses Lundahl transformers.

the standard stepped gain of 10db is rough tho, you'd def need a nice A/D w/ variable gain!

i've always wanted to run one of these w/ the 480's taboot, has anyone done that? whats it sound like? an m148?

Aerco's are cool.  Every one I have ever seen is beat to shit on the outside, which I assume has no effect on the sound!  ;)

I owned an MP2 for years and then sold it to Tom Joad. I loved it and ran it with AKG 460's, 480's and Schoeps CCM4's. It sounded great with all three combinations but expecially good with the 480's. It compliments mics that are quick and clean. What I find nice about them is not only the top notch transformers but the discrete based resistor pots.
