AT853 > 3Wire Box > R09HR vs. AT853 > ST-9100 > R09HR?
« on: March 02, 2009, 05:10:40 PM »
hi,
I'm using AT853 (mini-xlr) > 3Wire Box > R09HR to tape and I'm happy with the results.

now my question is: would a ST-9100 be a real and noticeable upgrade for my rig or R09HR internal preamp is good enough being better than classic R09 one?

thanks in advance for your help

I used to use the same rig. I noticed a big difference when I switched to phantom adapters > PS-2, but I'm pretty sure that was just because the PS-2 uses better quality components then the cheap electrolytic capacitors I put in my DIY 3-wire battery box.  For loud rock shows, you don't need a preamp. You will probably just end up using it like a battery box. If you tape lower volume shows, you might want to get one.
You either record it or it's gone forever.

I like having options...a preamp gives you that on top of clean gain.  For example, band plays a surprise acoustic encore. 
With the ca pre, isn't much bigger than a batt box.  Isn't gonna take up much more space in the chain and gear bag.

Those mics were designed to use phantom power, you should use it. Otherwise..you can head on over to that other thread and add to the 20 pages of speculation,bickering and confusion.

No, they were not actually.   They were designed to use 9v and accept 48v through step down adapters.  The extra 39 volts does nothing except maybe warm the resistors in the adapters a little.

They were designed to be ran off of a board for choir use, or with the belt packs, or with the packs serving as adapters from a board. They most definitely were not designed to be ran two wire off of an SP,CA or whatever battery box, nor were they designed to be hacked to "work" with said systems. Don't believe me though...call AT and ask them yourself.

The only reason they adapt to 48v is for convenience.  No need to bother AT, just bust out your multimeter and see for yourself.

Nameloc, I thought it was pretty clear to you and everyone else here that the supply voltage that is going out the mics on the hot wire is somewhere around 10 volts, when you use phantom adapters and a PS-2. (or any other phantom source for that matter)

Therefore, it is very simple to (almost) replicate this same power with a "3-wire battery box". It's just straight supply voltage. The only difference is that the power is unblanced, but for 4-5ft of cable, it doesn't matter.
You either record it or it's gone forever.

or with the belt packs

Psssst...the belt packs don't run off phantom. 

As other posters have pointed out, the AT853s are not designed from the ground up to run off phantom.  Rather the phantom adapters are a convenient way to get them to work with a mixing board when installed as choir mics.  Also a good way to interface them with an all-in-one deck like a PMD661 or FR2LE.

To the OP (BTW, your caps went in the mail today), I think the 9100 would be a worthwhile upgrade for acoustic music or even something like bluegrass through a PA system.  Amplified rock music, probably not so much.
