Première S is an active speaker and as such, requires no external amplification. However, most high-quality integrated amplifiers feature so-called “pre-outs”. These put out a line level signal, which can be used to drive Première. Depending on the model of your integrated amplifier, there might only be single-ended (Cinch) outputs.  Première can be used on single-ended outputs by using an RCA to XLR adapter cable. You can find and order an example of such cable at the link below: Thomann - RCA to XLR Adapter Cable
