Hi,
I know and use for the past 3 years a different version of it,
the preamp version with MS (internal MS matrix), the preamp goes up to 70db,
clean, 2 filters (100 and 150) it takes a 9v battery and mine can last
for about 2-3 hours with pair of AKG in MS mode, well built, a bit heavy,
but small, I adapt my microtrack 2496 with velcro to it, and I can go anywere
with it...
But i think this one is stripped version of it...
