First, ensure that the receiver is not on mute and that the correct input source is selected. Check speaker connections and ensure they are secure. If issues persist, try resetting the unit or checking for any blown fuses.
The Onkyo TX NR901 does not support firmware updates via USB or network. Check with Onkyo support for any manual update options or compatibility with firmware revisions.
Use an HDMI cable to connect the HDMI OUT on the receiver to an HDMI input on the TV. Ensure the receiver is set to the appropriate HDMI input source. For older TVs, component or optical connections may be used.
Connect your speakers to the appropriate surround output terminals. Use the setup menu to configure speaker distances and levels. Select a surround sound mode such as Dolby Digital or DTS for optimal performance.
Ensure the receiver has adequate ventilation and is not placed in a closed cabinet. Check for dust buildup and clean any vents. Consider using an external fan for better airflow. Reduce the volume level if overheating persists.
The Onkyo TX NR901 does not have built-in support for smartphone apps. Consider using a universal remote app with an IR blaster if your phone supports it.
The Onkyo TX NR901 does not have built-in Bluetooth. Use a Bluetooth audio receiver connected to the AUX or another audio input for Bluetooth connectivity.
Regularly dust the exterior and ensure adequate ventilation. Check all connections periodically for tightness. Avoid placing the unit in direct sunlight or humid environments.
Ensure high-quality speaker cables are used and that speakers are correctly positioned. Use the receiver's EQ settings to fine-tune audio output, and consider upgrading speakers for better sound quality.
