Choosing the Right Cables for Your AV Receiver

Your AV receiver is the central hub of your home theater system that ties all of your audio/video components together, but it's only as good as the cables you use to connect everything. Using the wrong types of cables or low-quality cables can negatively impact audio and video performance. In this blog, we will look at the different cable options available and help you choose the right cables to get the most out of your AV receiver.

HDMI Cables
HDMI has become the standard connection type for video and audio between most modern AV devices. HDMI allows transmission of uncompressed digital audio and video through a single cable connection. Here are some tips for choosing HDMI cables:

Cable Length - The longer the cable, the more susceptible it is to signal loss. For cable runs under 10 feet, any high-speed HDMI cable will work fine. For runs 10-25 feet, opt for a cable rated for that distance. For runs over 25 feet, you may need an HDMI cable designed for "extended distances."

Cable Type - The HDMI standard supports different bandwidth speeds. HDMI 1.4 and earlier support up to 1080p video. 4K/HDR requires HDMI 2.0 or newer. Make sure your cables are rated for the highest resolution your components support. Audio Return Channel (ARC) requires HDMI 1.4 or newer.

Future Proofing - Even if you don't have a 4K setup now, going with HDMI 2.0 or newer cables future proofs your system for potential upgrades down the line. Monoprice and Amazon Basics make affordable high-speed cables. For longer runs, try certified premium brands like Mediabridge or Ruipro.

Avoid Issues - Don't go too cheap on HDMI cables, as low-quality cables can cause video/audio dropouts. Stick with known cable brands rather than no-name generics.

Interconnect Cables
Most AV receivers still have analog audio inputs/outputs in addition to HDMI for connecting older or alternative devices. Here are some tips for interconnect cables:

RCA Cables - Standard RCA cables with left/right channels are needed for analog audio from devices like CD players, turntables or older devices without HDMI. Monoprice and Amazon Basics offer good, affordable options.

Digital Optical/Coaxial - Fiber optic or electrical optical cables are used to transmit digital audio formats like Dolby Digital from devices without HDMI to the AV receiver. Monoprice is a top budget choice here as well.

Speaker Wire - Most receivers have binding post outputs to connect speaker wire running to each speaker location. Opt for 14 or 16 gauge wire for most home installations. Amazon Basics is a solid budget option. Heavier 12 gauge is only needed for very long runs.

Avoid Low Quality - As with HDMI cables, super cheap no-name cables can cause signal issues. Stick with known cable brands for best reliability.

Audio Formats and Cables
Not all cables can transmit the latest and greatest audio formats. Here's a breakdown:

Dolby Atmos - Requires HDMI 2.0/HDCP 2.2 to pass object-based audio. Dolby Digital can also pass Atmos via PCM downmix over optical.

DTS:X - Also requires HDMI 2.0/HDCP 2.2 for object-based transport. DTS Core can downmix to legacy DTS codecs over optical.

Dolby TrueHD - Lossless format requires HDMI. Can be downmixed to lossy Dolby Digital over optical.

DTS-HD Master Audio - Also lossless, also requires HDMI. Can downmix to legacy DTS over optical.

Legacy Dolby Digital/DTS - Can pass over HDMI, optical, or coaxial connections.

So in summary - HDMI 2.0 or better is needed for the latest lossless object-based formats. Optical can still pass legacy lossy formats or downmixes.

Putting it All Together
To get the most performance from your AV receiver:

Use high-speed HDMI cables for all video sources and the TV connection where possible.

Consider HDMI cables rated for 4K/HDR if you have any components capable of those formats.

Use quality RCA, optical, or coaxial cables as needed for older device connections without HDMI.

Install 14 or 16 gauge speaker wire of a reasonable length for your room layout.

Test each cable thoroughly before finalizing your setup to ensure proper functionality.

With the right cable choices to match your specific components and installation, your AV receiver can deliver thrilling cinema-quality sound right in your home theater. Just be sure not to skimp too much on cable quality, as that's where many connectivity issues can arise. Follow these guidelines and you'll be well on your way to choosing cables that maximize your AV receiver's full potential.
