It looks like Nady and "SMPro Audio" are putting out the same 8
channel mic preamp under a different name, but for the same price:
$100!? Does anyone know who is actually building these things, and if
they are even worth throwing a hundred dollars at? What about any DIY
mods for them, anybody willing to take a look?

Actually, if you read the little blurb about each of them, it appears that
the Nady only has TS outputs, where the SM Pro Audio one has TRS. The Sm
Pro one also makes a point of saying it has balanced outputs. So, all else
being equal, it would appear that the Nady is the lesser "value" between the
2. Of course, not having heard either, it is difficult to say how good that
"value" may be. I'd be interested to read a review on it, if anyone manages
to turn one up.

The plot thickens. If you dowload the PDF manual for both units, it appears
that they may both be balanced. The manual for the Nady unit starts off in
the "features" section calling the output a TS jack, but later in the manual
it starts calling it a TRS, and also specifies that it is balanced. How odd
that they would let that get all the way to print with an error like that.
Especially since it is getting marketed against a rebadged unit from another
company, where it ends up looking like a lesser unit. I'll bet somebody is
saying "D'oh!" over that one!

Check out the "retail" prices: Nady $299, SMPro....$149! What are we
to make of that when they both sell for $100!?

Without seeing the unit or the schematic, I can't say for sure, but I
suspect that the balanced output consists of a fixed resistor between
the low side and ground. This does indeed make a balanced input do its
job of common mode noise rejection and costs only pennies, so it's a
worthwhile addition. If all other things are truly equal, it could be
the reason to buy one over the other.

On the other hand, I don't think that a $2/channel (plus chassis and
power supply and labor and profit) preamp is going to do anything but
make the microphone signal louder. This may be all you need, but it
isn't likely to be a quality improvement over anything you already
have other than perhaps a Soundblaster with a mic input.

That is just not enough money to build one very good mic pre, much less
eight.

Check out the TapeOp forum, I posted some comments on this about a
month ago.

Here are the basics of the SMPro version:

The unit has 3 PCB's

Power Supply Board: dual transformers, one for the +/-15V rails, one
for the +48V, just your basic regulated supply, nothing special.

Input Board: Basic transistor diff pair transformerless input.
Drives into a dual channel op-amp in series. Gain is set as an
attenuator between the two stages.

Output Board: Dual op-amp, no gain here, one non-inverting, one
inverting.

General comments:

47uF tantalum bypass caps between each stage (phantom decouple, stage
1 to attenuator, attenuator to stage 2, output of stage 2, output of
buffer), so 5 electrolytic caps in your signal change

All of the jumper wires (board 1 to gain set pot, board 1 to board 2)
are just plain wire, not shielded and use little plastic connectors
that are globbed with glue to hold them in place.

Op-amps are soldered in 8pin DIPs, but I socketed them and upgraded.

Overall nothing esoteric, just a simple by-the-book design, along the
lines of Mackie/Behringer. Note that the newer versions might have
been changed to surface mount, etc, but this is what mine was like.

At the price just buy one and report back to us. Of course you have to have
something reasonable to judge it against, and if you ask the question,
obviously you don't have something reasonable to judge it against. Thus, it
wouldn't make a single list of mine, even were I going to set up a recording
system for 12 year olds.

Geez, guys. Think. Use logic and reason. To make any profit at all the
parts have to be about $.37 total because it takes that little in parts to
make the production line work towards making any profit.

If any of you have been paying attention over the years, believe us, there
is no CHEAP way to go without getting CHEAP, particularly in the range of
electronics. I'll take some of the mics that have been coming out for
little money, but let's face it, unless you can pinpoint where you could use
them, they are a worthless investment too. To look at an 8 channel mic pre
that sells street for $100 you might as well just go ahead and get it
because it might do something for you. But ultimately, if you have any ears
at all, you'll drop it like a hot potato and consider that you've learned a
lesson. The real lesson is don't buy crap and then you won't have crap on
your hands.

Implied? I don't think so. I was pretty specific. I don't recall seeing
anything in your question about changing out parts and making something out
of nothing. I said specifically that if you didn't have something to judge
it against than you wouldn't know what it sounded like. If you do, then for
$100 be brave and figure it out for yourself. I mean, if we were talking
about $2k then I'd understand, but you know the name, you know the
reputation, and yet you ask the question without the stipulations. I simply
answered on that level. If you took offense then I apologize. I wasn't
trying to offend you. But the answer is still the same, regardless, and
it's come at the expense of my wallet more times than once. Perhaps instead
of ragging on you, I was reminding myself of lessons learned dearly? Your
call.

If you wanted to do a professional job of this, you'd start out with a
level-matched, time-synched, bias-controlled listening test and some
technical testing.

From Dave Runton's description, the most obvious sound quality exposure
would be the unbiased tantalum coupling caps around the gain control and
outputs.

Ironically, $100 will get you the rack chassis, maybe parts for the power
supply, and possibly some or all of the connectors. If you start with a
SMPro Audio you get the chassis pre-punched!

Roger,

Using some of your original logic, I'd say that the FMR RNC must be a
piece of crap...I mean you get four channels of compression for only
$175, that's only $44 per channel, I mean how good can the thing be at
that price. If an 1176 costs $1500 per channel, at $44 per channel
this RNC thing must be a total piece of crap, right?

I'd suggest the usefulness of this preamp would be for the guy that
wants to record 8 tracks and doesn't want to string together two
Mackies to do that.

While I'd agree with the logic of spending your money on useful tools
that will last (e.g. $2000 mic pres), when someobody's entire setup
costs that much it's kind of a stretch to justify spending $2000 on
something when the rest of your signal chain is not there either. Keep
in mind that not everybody's recording/music career is for life, some
people wind up dropping out. Then there are the sick pups like us g

I did plenty of recordings in my youth on crap gear and I can't really
say the music would have been better if I had good gear...the
recordings yes but not the music.

My drummer is thinking about buying one of these pres for live
recording, his side bands (Country Band, big band, etc.) Nothing
serious mind you, just capturing a live performance to his DA78.

For him it would be a lot more convenient than dragging out two 1202's
to do the same thing.

If he gets the thing I'll A/B it with my good **** (GR, Hardy) and my
so so **** (Rane and Symetrix) and report back.

You've got a point there. I know that people who pay outrageous prices
for Ampex MX-10 mixers essentially remove all of the components and
replace them all (and figure that they're getting a bargain for a four
channel toob mic preamp).

Still, a message asking about a new product to be purchased for the
primary purpose of modifying it seems a bit out of character here from
someone who isn't known as a builder. If Justin had asked this, I
wouldn't have been surprised.

That's all my great River MP2 seems to do. I suspect for $2/channel it's
changing the mic's signal substantially.

How do I tap into the other 2 channels of my RNC?
