icepower 500/1000ASP power by battery (DC input)?
 
Anyone can post which pin is for the DC power input because I would like to use battery power the amp?

Anything can do in the analogue part that can improve the sound?

Check the data sheets for the modules, and you'll find there is no DC input.

The A series 250A, 500A can be battery powered, and were used in the Presideo products on 48v DC battery rail (36 min 56V nominal or 4 series 12v sla batteries to be exact!); however they also need low current +- 12 to 15V rail as well.

You can use DC power in on the ASPs if you want because the SMPS rectifies the AC line voltage, but your min. voltage would then be equal to 85VAC rectified or around 120VDC, which isn't really pratical on batteries if you ask me. If you want to play with this, get some 250A/500A/200ACs instead (and some fuses)!.
