Using these Martin MAC Viper AirFX fixtures is easy. First, make sure you connect them to the correct power supply provided. When you're ready to use them, turn them on and start creating amazing aerial effects. Keep in mind that one unit is missing a button cover, but it won't affect the overall performance.
