Chinese screens were originally made to set behind emperors' thrones. Screens were made from wood and silk to signify the emperor's authority. Today, they are used in homes of varied interior design. You can find screens made from lacquered wood, jade, ivory and metal. Because of the weight of most Chinese screens, they are generally not hung but used as a way to separate rooms. However, you can use yours as wall decoration as long as you have sturdy hanging equipment.
A mixer is used to control the level, timbre and dynamics of multiple audio tracks. Mixers are used by both live and studio musicians.

Unpowered mixers require a separate amplifier.
