A soundbar offers a significant upgrade with a compact footprint, while an AV receiver paired with separate speakers provides the ultimate in flexibility and sound customization. Regardless of the choice, ensuring a robust connection from your source or projector to your external audio device will yield a substantial improvement in sound clarity, volume, and overall impact.
What is HDMI ARC and why is it useful for projector audio?
HDMI ARC (Audio Return Channel) is a feature of the HDMI standard that allows audio to be sent “upstream” from your TV or projector back to your soundbar or AV receiver using the same HDMI cable that carries the video signal to the display. This means you can use a single HDMI cable for both video and audio transmission between your source device, projector, and audio system, greatly simplifying your cable management.
The usefulness of HDMI ARC lies in its convenience and ability to support more advanced audio formats than traditional analog or digital optical connections, especially with the newer eARC standard. It eliminates the need for a separate audio cable from the projector to your sound system, making setup cleaner and more straightforward, while still enabling high-quality audio playback, including surround sound.
How do I connect my projector to a soundbar or AV receiver?
To connect your projector to a soundbar or AV receiver, you’ll generally connect your source device (like a Blu-ray player, gaming console, or streaming stick) to the AV receiver or soundbar via HDMI, and then connect the AV receiver or soundbar to the projector via HDMI. If your soundbar or AV receiver supports HDMI ARC and your projector has an ARC-compatible HDMI port, you can simplify this by connecting the source to the projector and then using a single HDMI ARC cable from the projector’s ARC port to the soundbar/receiver’s ARC port.
Alternatively, if HDMI ARC is not an option or you prefer a different setup, you can connect your source devices directly to the projector via HDMI for video and use separate audio cables to route the audio from the source device’s audio outputs (e.g., optical audio, 3.5mm headphone jack) to your soundbar or AV receiver’s corresponding audio inputs. This approach requires more cables but offers flexibility in how you manage your audio signal.
