About the Metra Helios CS-HDMAV

Use an HDMI source with an older TV

This scenario might sound familiar: you have an older TV that doesn't have any HDMI inputs, but you want to connect a high-definition source like an Apple TV, Blu-ray player, or cable box. If that's the case, consider using the Metra CS-HDMAV. It takes an incoming HDMI input, and converts it to composite video and RCA stereo audio. This lets you use the yellow (video) and red and white (stereo audio) inputs on your old-school TV to watch an HDMI source.

Product highlights:

  • connect an HDMI source to a TV that doesn't have HDMI inputs
  • takes the incoming signal from an HDMI cable and converts it to composite video and RCA stereo audio
  • features a selectable video output format switch (NTSC and PAL)
  • plugs into a USB power source
  • HDMI cable and composite video/audio cables not included
  • warranty: 1 year
  • Our 60-day money-back guarantee

Product Research


HDMI to Composite AV Converter: The HELIOS CS-HDMAV is a HDMI to composite AV converter. It takes a HDMI audio/video signal and converts it over to composite video and stereo RCA.

HDMI Input: The HELIOS CS-HDMAV is equipped with a female full-size HDMI 1.3 input. HDMI cable sold separately.

Analog AV Output: The CS-HDMAV is outfitted with a composite video output and stereo RCA audio outputs. Composite video and stereo RCA cables sold separately.

Supported Video Resolutions: The HDMI input will accept 480i, 480p, 720p, 1080i, and 1080p video signals. The composite video output only supports 480i, so any higher video resolutions will be down-converted. The CS-HDMAV can be set to PAL or NTSC video.

Supported Audio Formats: The HDMI input will accept 2ch to 5.1ch audio (including Dolby Digital & DTS). Multichannel audio will be down-converted to 2-channel through the CS-HDMAV's stereo RCA outputs.

Power Requirements: The HELIOS CS-HDMAV features a miniUSB port and comes with a 29" miniUSB-to-USB cable which must be connected to a USB power source (not included).

Customer Q&A

3 questions already asked

I have a Samsung QLED 4K TV. I want to connect to a home theatre system (HTS). I connected the HDMI input to the converter, connected the USB power, set the switch to NTSC and the RCA output to my HTS. I get no sound. Is this device QLED 4K compatible? What do you recommend?

CS-HDMAV says it's to connect an old TV with no HDMI port to new device. I need the reverse. I need a composite for my Bose Lifestyle 28 system to connect via HDMI to my new Sony smart tv. Will this item work? Also need the cable?

These converters send the signal in one direction and do not come with cables. They are also made with the composite output and the HDMI input and needs power source. The cable for this comes with it, but the other end is USB. Figure out what you want to convert from and to, will tell you which direction to select. Your description sounds like you want to send the sound from your TV to your Bose system so you need HDMI input to composite output.

Best and most economical way to mirror my cell phone to my 2018 nissan rogue with nissanconnect without navigation? Thank you!

We are usually not able to mirror a smart phones onto a stock radio as those radios don't usually have an A/V input on them; just a aux audio input. But aftermarket radios have ways to possibly mirror phones. I recommend contacting an advisor on 1-800-324-9695 or through our online chat to get a personal recommendation on this. My Bio:

I purchased this cable to play my Classic IPOD through my home theater receiver and it works perfectly. I'm sorry I can't answer your specific question. One thing for sure, the price of this cable is very affordable.
