When only my Oppo 105 is plug to PPP, the output distortion is around 0.2 and 0.3%. Added my JVC X-35 projector, it increased to 1.0%. Is it normal? Will that affect my Oppo 105 audio and video quality? Any advice?
Your projector is probably drawing a lot of current and making the PPP work harder. This is normal for a big load.
It will affect the Oppo, but shouldn’t be too bad.
