7 channels
I find them quick and trs function that turns on the music rytme DMX is nice especially for a DJ who has no time to do it all the time and want to be able, when he wishes, to direct his scan.
Weight & size ridicule are its strong points (ds 2scan a suitcase or the range is normally 100cd)
Its brightness a little "light" (100W) especially in big accessories and price if given as ca (especially when you see the market right now) are his Pricipals dfaux

Finally, a scan useful for small mobile disco, but not enough I think for higher benefits.
