• Constant current outputs in T1/T2 channels.
• Individual T1 channels for each color.
• Alternative DC +/- outputs between image & non-image periods in T2.
• AC + DC MHV Bias.
• Rated loads in all channels could be change according to the environmental conditions.
• All output channels can be adjusted by using volume control components.
