TX-RZ70 - Troubleshooting: USB Port

Video or audio is unstable when a streaming device is connected to the USB port of the AVR for power supply. The power output capacity of the AVR's USB port is 5V/1A. If the device’s power requirements exceed this limit, it may not function stably.

In such cases, you will need to use the adapter provided with your streaming device for the source to have stability in Audio/Video playback.
