With a whole-house audio system, you’ll enjoy great sound in the rooms you choose, but one person may like to shake the roof off while the other likes it mellow. That's where volume controls come in very handy. OSD Audio’s wall-mounted volume controls are an affordable, easy way to control speaker volume independently in each zone. Whether you choose knob control or soft-touch sliders, OSD Audio offers convenience and style with colours to match any decor. Quality is critical to the successful sonic performance of any whole house audio system. After all, it’s about how the system sounds and how well it works. From front to back, our pro-instal series is built with close attention to performance, reliability and durability. The result is a blend of transparency and functionality, with low distortion and ruler flat frequency response. We bring you seamless control for every room in the house.
