LAB POINTS adds convenience to manual turntables by automatically raising tonearm at the end of the record can be configured to work with most turntable models (note: does not work for DJ style turntables, see compatibility below) trigger and lift design, no battery required helps to extends stylus life easy installation, no tools required adjustable base allows you to position at different heights based on tonearm height only interacts with tonearm at end of record, does not affect sound quality COMPATIBILITY your turntable must have a pivot type tonearm (any turntable where you can lift and pivot the tonearm to a specific point on the platter) and NOT linear tracking you will need at least 14mm of space between the tonearm and the platter the minimum height between the turntable surface and the tonearm when playing a record must be 36mm if you are using the base unit, OR 34mm if you are setting it up without the base unit. "the Q Up is NOT compatible with DJ style turntables like the Technics 1200, Audio-Technica and Stantons. there is no space between the platter and the tonearm to mount the lifter."
