The Ultra Systems Adapter Rings are the solution for two specific challenges:
1. Although 7" and 10" Vinyl discs should theoretically be the size they're advertised as, these discs actually vary significantly from these diameters. This makes the development of a one size fits all adapter very difficult. The design Ultra Systems and Gingko Audio came up with works for almost all 7" and 10" discs.
2. Because 7" and 10" discs have different sizes of center labels than 12" LPs, the other diameter of the adapter rings can't actually be 12". Once again, finding a happy medium to adapt the entire spectrum of discs was a challenge.
The 7" and 10" Vinyl Adapter Rings work well and are easy to use! The Ultra Systeme adapter rings come bundled with one adapter each for use with 7" and 10" discs, packaged in a gatefold jacket, like a double LP.
*Special Note: The Audio Desk Systeme Vinyl Cleaner Record Cleaning Machine is sold separately.
