Denon AVR-790 user manual

There could be several reasons why there is no sound coming from your Denon AVR-790 receiver. Here are a few troubleshooting steps to help identify and resolve the issue:
1. Check the power: Ensure that your receiver is turned on and connected to a power source. Make sure the power cord is securely plugged in and that the power indicator light is illuminated.
2. Speaker connections: Confirm that the speaker wires are properly connected to the receiver and speakers. Make sure the positive and negative terminals are correctly matched.
3. Input selection: Ensure that the correct input source is selected on the receiver. Use the remote control or front panel buttons to cycle through the inputs and make sure you have selected the appropriate one.
4. Volume levels: Check that the volume level on the receiver is turned up. It's also a good idea to verify whether the volume is muted or set to a very low level.
5. Speaker settings: Review the speaker settings menu on your receiver. Ensure that the correct speaker setup (e.g., stereo, surround sound) is selected, and that the speaker size, distance, and crossover settings are appropriate for your setup.
6. Test different inputs and sources: Try connecting various audio sources (such as a TV, DVD player, or gaming console) to different inputs on the receiver to see if the issue persists across multiple sources. This can help determine if the problem lies with a specific input or source device.
7. Factory reset: If none of the above steps work, you may consider performing a factory reset on your Denon receiver. Please refer to the user manual or Denon's support website for instructions on how to do this, as the process may vary for different models.
If the issue still remains unresolved after attempting these steps, it may be best to contact Denon's customer support or a professional technician for further assistance and troubleshooting.

HDMI Control, also known as HDMI CEC (Consumer Electronics Control), is a feature found on Denon receivers (including the AVR-790) and other HDMI-compatible devices. It allows for simplified control and communication between devices connected via HDMI.
When HDMI Control is enabled on a Denon receiver, it can interact with other HDMI devices connected to it, such as televisions, DVD players, Blu-ray players, gaming consoles, and more. This feature enables functions like power on/off synchronization, audio and video control, and input switching.
For example, when you power on your TV or Blu-ray player, the HDMI Control feature can automatically turn on your Denon receiver and switch it to the appropriate input. Similarly, turning the receiver off can toggle the connected devices into standby mode.
HDMI Control streamlines device operation by allowing a single remote control to manage multiple supported devices. Moreover, it simplifies the overall setup and eliminates the need for additional remotes, enabling a more convenient user experience.

To access the setup menu on the Denon AVR-790 receiver, follow these steps:
