Check if there is an earth/ground connection in the audio system as we suspect it is missing.
Due to the rules about EMC the iPower contains a so-called Y-capacitor. This drains noise via the power supply unit connection to earth/ground. This is a direct result of the way tests are arranged and outside our control. It is not possible to pass EMC otherwise.
If there is no earth/ground connection in the system, noise may be radiated through the system ground and cables (which can make a very efficient antenna) and interfere with the wireless network.
If no earth/ground present in the system the GroundHog+ maybe deployed to implement a ground/earth.
If you are not sure please open a support ticket with us as this topic can be a challenge to diagnose if not sure.
