preamp for binural

[fweqy]

hello

im new here just saw you all on google

i have a couple of laverler mics and a trv900e sony camcorder (48kh)
the pre amp is of course horrid and hissy so i am looking to upgrade the pre amp to do some binaural recording.

maybe someone might have an idea how i could upgrade i have a an e-mu 1616m but i cant seem to use the preamps unless it is atached to a computer( maybe i could trick it ?) i also have a vs 1680 i opened it up to salvage the preamps but they are atached to a large circuit board not really snatchable..i have a tascam ma-ad8 preamp rack unit ive yet to look inside maybe i could rip a couple from there?

otherwise i havent much money around 350 uk pounds ( <edit) any ideas or know of a great portable pre i could buy?


thanks for any help :P

For great / portable pre you're probably looking at a Sonosax SX-M2 or Korg MR-1000, among others. Assuming you also need phantom power. And battery power.

For $100 you'd be hard pressed to pick up an M-Audio DMP-3 (used). Which runs on a power tether, so not very portable. But functional and decent for all intents and purposes. You could always go with a Radio Shack mic with an AA or AAA battery setup. Delivers fair results and doesn't require a preamp. But if you're going for PRO results, you may still feel disappointed.

At the moment I'm leaning towards a Crown Sass-P MK II mic which can run on 2x 9V batteries. But will probably still require a preamp.

hi thanks for your reply

ive had in idea:

how about buying 2 x mono pre amp circuit boards without a case/shell
then mounting in a cheap home made case? phantom power module can
be added and even pots for attenuation.xlr sockets and psu with a battery pack??

i wonder if you can buy one from a spares repairs work shop??

peace

Dynamic range: 120dBA

Frequency response: 20Hz to 20kHz +0/-0.03dB.
THD + noise: -105dB (0.0006%) 1kHz signal at -1dBFS.
E-MU XTC Class-A, ultra-low noise preamps (-129.5dBu

And below a sonax

Type
:
balanced transformerless, XLR connectors

Impedance
:
5k Ohms , 20Hz to 20kHz
Gain
:
76dB to 20dB (high), 40dB to 6dB (lo), 0dB (center)



Frequency response
:
±0,5dB, 20Hz to 20kHz

Crosstalk
:
better than 75dB, 20Hz to 20kHz
THD
:
less than 0.01%, 20Hz to 20kHz at +6dBu, less than 0,03% at +20dBu
Noise 76dB gain
:
better than -129,2dBu, 20Hz to 20kHz, 150 Ohms source

im hoping for a portable stereo preamp....i might just get a very cheap laptop and use my emu 1616m?
as it is a card bus version.
ive managed to scrap up bout 350 uk pounds to spend

thanks for any help

core-sound has some mini-preamp / binaural systems
