This mixer is easy to use, it works like any analog mixers.
The main settings are on the front pretty easy.
Operates on either AC adapter or two 9V batteries, cete mixer is unfortunately intensive battery.
Of preamps that provide quality that add color to the sound that makes the charm of this mixer.
I do not have this mixer but I used it several times with different micro (Schoeps MK4, Neumann KMR 81 ...) I compared with several mixers (SQN, Sony ...) the sound of the AT 4462 is really impressive, a color the sound, micro ring, once passed through the mixer.
It is unfortunately quite rare as most manufactured for quite some time.
I put 9.9999999 / 10 although I do not know the price, I do not put 10 because it is heavy on 9V battery.
