dvsDave and I really liked the products made by Nu Delta Digtial and we also really like the guy behind them. Nu Delta Digital is the brain child of University of North Carolina Greensboro's lighting and sound faculty Noah Davis. Noah saw a need for a product and had the skills to make it happen. In this video he shows us his DMX tester. It's reasonably priced, easy to operate, and easy to teach. Great products, at reasonable prices, from a great company, that's a win all the way around.
