Salling, 35, now faces between four and seven years in prison and has been ordered to pay about $50,000 (£38,000) to each victim.
The actor was arrested in 2015 after a tip off he was in possession of images of children being sexually abused.
Investigators eventually found thousands of images on his laptop and hard drive.
Salling was charged with two counts of receiving and possessing images of child sexual abuse in May 2016, and faced a possible 20 years behind bars.
