If you’re looking to level up your karaoke sessions, livestreams, or podcast recordings, the F999 Sound Card is one of the most affordable and beginner-friendly audio mixers you can use. It works well with phones, laptops, and even tablets — perfect for content creators, singers, and vloggers on a budget.
What’s in the Box (F999 Basic Inclusions)
- F999 Sound Card unit
- 3 audio cables (usually 3.5mm TRRS cables)
- Charging cable
- Earphones or headset
- Microphone (condenser or dynamic, depending on model)
Step 1: Charge the Sound Card
Plug the F999 into a USB charger using the micro USB cable. Charge fully (usually takes 1–2 hours). The light will indicate when it’s fully charged.
Tip: Always charge it before use to avoid audio issues mid-performance.
Step 2: Connect Your Microphone
Plug your 3.5mm condenser mic into the “Mic” input. If you’re using a headset with a mic, plug it into the “Headset” or “Earphone” port instead.
Use only one mic input at a time to avoid interference.
Step 3: Connect to Your Phone or Laptop
Use the audio cables labeled “Live” and “Accompaniment.”
For Live Streaming or Recording:
- Plug one end into the “Live 1” or “Live 2” port.
- Connect the other end to your phone’s mic jack (or use a Type-C/Lightning adapter).
- Open your Facebook Live, TikTok Live, or recording app.
For Karaoke Music Input:
- Plug one cable into the “Accompaniment” port.
- Connect the other end to your music source device (another phone, tablet, or laptop).
Step 4: Plug In Your Headphones
Use the “Headset” or “Earphone” port to monitor your voice and background music.
Tip: Use noise-isolating headphones for best results.
Step 5: Adjust the Settings
- Mic Volume – Adjust your voice level
- Echo/Reverb – Add a karaoke/studio effect
- Music Volume – Controls background music level
- Record Volume – Balances voice and music mix
- Monitor – Toggle voice monitoring on or off
You can also trigger built-in effects like claps, laughs, cheers, or gunshots using the buttons.
Step 6: Test Before Going Live
Play a karaoke track from your music device. Sing into the mic and listen using your headset. Adjust echo, music, and mic volume until you’re happy with the balance.
