This demo video does not do this laser justice it's absolutely amazing in the right conditions with a little smoke . It uses the old trip switches to select different operating modes although it's DMX ready I've only used it in pre programme demo and sound to light mode as in the video . I must admit the mic sensitivity is extremely poor and you have to have a LOUD system to get it to dance or even move in sound to light mode even with the sensitivity turned right up that's my only criticism the complete opposite of the Tri phase which is too sensitive. Unfortunately I can't locate the keys at this present stage . Other than that it's any amazing old skool rave laser and extremely rare whoever buys will not be disappointed. Thank you for viewing.
