Ideal for Integrated Speaker Systems
The SB-6.1 provides a central connection point between installed speaker cabling and an amplifier or home cinema system. Recessing the connections into the wall helps reduce visible cabling and creates a cleaner finish around entertainment equipment.
Before Installation
Check the wall construction, available depth, cable routes and surrounding services before preparing the opening for the Syncbox. The required depth is greater than that of a typical socket installation, so suitability should be established at the planning stage.
