Ensure you have the correct types of connectors for both your AV receiver’s output ports and your projector’s input ports, paying close attention to the labeling on each device.
How do I connect the audio output from my AV receiver to my projector?
The most straightforward method is to use the HDMI cable connected to your AV receiver’s HDMI OUT (ARC/eARC) port and your projector’s HDMI IN port that supports ARC/eARC. This single cable will transmit both the video signal to the projector and the audio signal from the AV receiver back to the projector, assuming the projector has speakers or audio output capabilities. This simplifies wiring and ensures a seamless audio-visual experience.
If your projector doesn’t support ARC/eARC or you prefer a separate audio connection, you can utilize the audio output ports on your AV receiver, such as optical (Toslink) or coaxial digital audio out, and connect them to the corresponding audio input ports on your projector. Alternatively, if your projector has analog audio inputs, you could use RCA stereo cables from your receiver’s analog audio outputs, though this is generally not recommended for modern home cinema setups due to potential signal degradation.
What is the correct HDMI port to use on my AV receiver and projector for the best connection?
For optimal performance, especially with modern video and audio formats, you should prioritize using the HDMI ports labeled as ARC (Audio Return Channel) or eARC (enhanced Audio Return Channel) on both your AV receiver and projector. These specific ports allow for two-way communication, enabling audio to be sent from the projector back to the receiver, which is crucial for utilizing the receiver’s advanced audio processing capabilities with content played directly through the projector’s smart features or connected devices.
If neither device has ARC/eARC capabilities, or if you’re experiencing issues, use any standard HDMI OUT port on your AV receiver and connect it to any available HDMI IN port on your projector. However, be aware that this configuration will only send audio from sources connected directly to the AV receiver to the projector’s speakers, and you won’t be able to use the projector’s internal audio output capabilities with the receiver’s processing. Always consult your device manuals for the specific port functionalities.
How do I configure my AV receiver and projector settings after connecting them?
Once the physical connections are made, you’ll need to access the settings menus on both your AV receiver and projector.

Yes, you can connect devices like Blu-ray players or streaming devices directly to the projector’s HDMI input ports. This is a perfectly valid setup, especially if your projector has multiple HDMI inputs and built-in smart features or a robust audio system. This direct connection allows the video signal to go straight to the projector for display without passing through the AV receiver, which can sometimes simplify the signal path.
However, if you connect sources directly to the projector, you will bypass the AV receiver’s audio processing capabilities and its surround sound decoding. This means that the audio signal will either be processed by the projector’s internal speakers or sent out via the projector’s audio outputs to an external sound system. For the immersive audio experience that an AV receiver provides, it’s generally recommended to route all your sources through the AV receiver first.
What is the purpose of the HDMI ARC/eARC feature when connecting my AV receiver to my projector?
The HDMI ARC (Audio Return Channel) and its enhanced version, eARC (enhanced Audio Return Channel), are designed to simplify your home cinema setup by allowing audio to travel in the reverse direction on the same HDMI cable used for video. This means that audio signals from your projector, such as from its internal apps or connected USB devices, can be sent back to your AV receiver for playback through your surround sound system. This eliminates the need for a separate audio cable between the projector and the receiver.
eARC, specifically, offers higher bandwidth than standard ARC, enabling it to support uncompressed, high-resolution audio formats like Dolby Atmos and DTS:X, which are crucial for a truly cinematic audio experience. By utilizing ARC/eARC, you can enjoy the full audio capabilities of your AV receiver even when using the smart features built into your projector or when the projector is the primary display device receiving content from other sources.
