The only way possible, to connect a receiver, would be through a 2.5mm out. (A headphone style jack). If that was done correctly and the volume placed properly on the speaker set, I don’t see why it couldn’t be done. You would have to balance the volume knob on the speaker set and then use the receiver volume as your control. Should work. Not sure why you’d connect a powered set of speakers to a powered amplifier, definitely not an optimal set-up but certainly possible.
