Type C to RCA Coaxial Cable: Connect Your DAP to Home HiFi

Quick answer

Connect a Type C to RCA coaxial cable from your HiBy DAP's USB-C port to your amplifier's coaxial input, then set the DAP to output digital audio via USB. This wired link bypasses your player's internal DAC and sends a clean digital signal to your home HiFi. It works best when your DAP supports USB audio output and your amplifier has a coaxial input.

What you need before you start

You need a HiBy DAP with a USB-C port that supports digital audio output, a Type C to RCA coaxial cable, and a home stereo amplifier or receiver with an RCA coaxial input. Check your amplifier's manual to confirm the coaxial input is for digital audio, not analog. If your amplifier only has optical or analog inputs, this cable won't work; you'd need a different adapter.

Step-by-step connection

Follow these steps in order. Each step includes a common mistake to avoid.

• Step 1: Power off both your DAP and amplifier. Mistake: connecting cables while devices are on can cause pops or damage.
• Step 2: Plug the Type C end into your DAP's USB-C port. Mistake: forcing the connector; it should slide in smoothly.
• Step 3: Plug the RCA end into your amplifier's coaxial input. Mistake: using an analog RCA input like AUX or CD; those won't decode the digital signal.
• Step 4: Power on the amplifier first, then the DAP. Mistake: turning on the DAP first can cause handshake issues.
• Step 5: On your DAP, go to Settings > Audio > USB Output and select 'Coaxial' or 'Digital'. Mistake: leaving it on 'DAC' mode; that sends analog audio and won't work.
• Step 6: Set your amplifier to the correct coaxial input. Mistake: forgetting to switch inputs; you'll hear silence.
• Step 7: Play a track and slowly raise the volume. Mistake: starting at high volume; digital signals can be loud.

Troubleshooting common issues

If you hear no sound, check that the DAP is set to digital output and the amplifier input is correct. Some DAPs require you to enable USB audio output in settings. If you hear static or dropouts, try a different cable or check for loose connections. Remember, this cable only works with devices that support USB digital audio output; not all USB-C ports do.

Your step-by-step checklist

1. Power down: Turn off both DAP and amplifier before connecting. Prevents electrical pops.
2. Connect cable: Plug Type C into DAP, RCA into amplifier's coaxial input. Ensure snug fit.
3. Set DAP output: In settings, choose USB digital output (coaxial). Avoid analog mode.
4. Select input: Switch amplifier to the coaxial input you used. Check labeling.
5. Test and adjust: Play music, start volume low, then adjust. If no sound, recheck settings.
