If the Orbit does not have the optional built in phono preamp then you need to connect one between the Orbit and the Edifier powered speakers.

A $16 Pyle PP555 may be sufficient for the basic Edifer speakers or the $49 Technolink should be more than sufficient.

The A5+ doesn’t include preamp either. Just put a preamp between your orbit and SMSL like https://www.amazon.com/Pyle-Phono-Turntable-Preamp-Preamplifier/dp/B00BG2H95K
