For DJs who are meticulous about their live sound preparation and reliability, the Booster Stackable Rubber Discs for Shock Absorption (12-Pack) from Jetpack reduce vibration and shock for turntables and other DJ gear, so you can rest assured that low-frequency interference will never jump your needles. Space is created underneath to stow cables, so unstable or unideal height surfaces are no longer a problem. Constructed with durable EPDM synthetic rubber and measuring 1" in height when stacked, you have the ultimate control over your gear setup.
