Yes, you can use the Denon Remote App available for iOS and Android devices. Ensure your AVR-E400 is connected to the same network as your smartphone to control various functions.
Ensure that all HDMI cables are securely connected and of high quality. Try powering off all devices, then power them on in the following order: TV, AVR-E400, and then the HDMI source device. Check the input source settings and update the firmware if necessary.
Connect the speakers to the corresponding terminals on the AVR. Go to the setup menu, select "Audio," then "Speaker Configuration," and choose "5.1" from the options. Adjust the speaker levels and distances according to your room layout for optimal sound.
