I adjusted the polarity in the order of amplifier, router, modem, and set-top box. Strangely, the LEAK amplifier is manufactured with the polarity reversed. I don't know if all LEAK amplifiers are like that or if they are manufactured without care and each one is different. iPad - Even though I connected it directly to the amplifier with a USB cable, I connected it to the router's Wi-Fi, so the polarity of the router, modem, and set-top box is affected.
What do you mean before and after. Before and after what??
