I recently upgraded from an all-in-one turntable to an actual system, but I'm still new to vinyl.
I got a Pro-Ject Debut Carbon DC, a Behringer PP400, and Audioengine A2+ speakers.
I set everything up accordingly, connected the turntable to the phono preamp (input?), and bought an RCA cable to connect the speakers to the preamp also (output to output?). The sound came out of only one speaker (I can probably just check the left speaker's connection to the right myself) and it was extremely quiet even on max volume.
Did I set something up wrong? Are any of the items not compatible? Thanks a lot
