SC3 FAQs

User Manual

Software upgrade

Since the version of SC3 with the feature of computer audio loop hasn't been available for quite a while, it's not quite likely that you will get one. We would suggest checking the input and output device under computer and software setting, especially if you're using the virtual audio from apps like Voicemeeter.

If you're still quite confused about why you get the echo from SC3 but everything gets normal when not using the mixer, or you want to confirm whether you get the version with computer loop from some third-party sellers, please reach out to our support team at web@fifine.cc to get helped out.

Basic information

USB mics are built to get rid of an external sound card, and a large part that you paid for a USB mic is for its built-in sound card. There's no necessity to bypass the internal one and spend the extra on external ones, like this SC3.

Yes, SC3 has an XLR combo 6.35mm port, so you can use either an XLR or a 6.35mm mic with it.

⚠️But note that:
1️⃣Since XLR condenser mics need 48V power through XLR connector, please make sure you use the XLR to XLR cables(⚠️not included) for connection.
2️⃣SC3 audio mixer provides 50dB gain, so when you used a dynamic mic that needs more than that and you thought the audio is a bit low, you may need a cloudlifter to boost the gain.

No, we're sorry that this SC3 audio mixer comes with the type-c to type-c & a combo cable and 3.5mm to 3.5mm cable.

1️⃣You need to connect the A40 headset to the SC3 headset port.
2️⃣And instead of using the included cable, you need to buy a TRS to TRRS cord to plug the TRS end to the SC3 line-out while the TRRS end to the Mixamp headset port. But please lower the Mixamp input volume.
3️⃣The setting of the Mixamp on PC or PS4/5 remains the same.

But we don't recommend buying the SC3 if you only want to use the change voice feature and already own a Mixamp. The setup will become so complicated and make not much sense.

As a rule of thumb, you can check if your headsets meet the aspects below to get an idea of whether the SC3 will work. If you're not quite sure, feel free to contact us at web@fifine.cc
✔️3.5mm Wired Headsets for sure. Just plug it into the headset port of the SC3.
3.5mm Wired Headsets with a DAC. In most cases, they should work as long as your DAC has a 3.5mm headset port as well as a line-in or AUX input.
❌Wireless headsets/❌Wireless headsets with a DAC/❌Wired headsets but no 3.5mm connector are all no-no.

We really don't recommend using it for that purpose, it's just not built for dual setup in the first place.

But if you really want to try it out, it's also quite easy to set it up.
1️⃣Plug the mixer to the gaming PC through USB.
2️⃣Next, if your streaming computer is a PC, you can use the included audio cable to connect the line-out of SC3 to the mic jack of your PC.
3️⃣If it's a gaming laptop, then you still need to find a TRS to TRRS 3.5mm audio cable. And that's all.

But the problem is that when you're connecting your streaming PC with a line-out jack, you can't hear sound back from your streaming, like the Twitch notification or something. If you're connecting the mixer with a streaming PC through USB, you can send and hear audio back from it, then the problem is that you can't chat with your friends on the gaming PC or chat with them, but they hear the echo sound of the game.

PS5✔️ for sure. We have the exact tutorial on how to set it up with PS5 here https://www.youtube.com/watch?v=OF-vMOlZbpQ

Xbox❌ is a no-no. Third-party USB audio devices aren't allow to work with Xbox, this SC3 is no exception.

No, it's not something that it can do, but you can set up and adjust the sound from the gameplay and voice chat separately on OBS. But it has nothing to do with the mixer.

If you need the physical dial to control the level of game and chat, take a look at the AM6 USB condenser mic, which may surprise you with what it can do.

Installation & Setup

1. Check if the SC3 mixer is set up as default input and output device in both systen sound and software audio setting.
2. Make sure that the mic channel is not muted, in which the mute button doesn't turn on white light, and the microphone fader isn't all the way down to zero.
3. Turn on the MIC MONITOR. After that the button will keep solid white light.
4. If a headset is connected to the headset port while the mic is plugged into the XLR port, headset will take the priority of audio input. Thus, if you don't the headset mic audio, just plug the headset into the headphone port instead for listening purpose.
5. Check whether your mic need 48V phantom power or not. If yes, then turn on the phantom power with the 48V button, in which it will turn on white.

You can also refer to the video below to run the setup or troubleshooting process.

Just use the included 3.5mm TRS to TRS cable to connect between the headphone jack of phones or iPads. But make sure it must be the cable with two black poles on each end.

1. Long press the button until the it turns on white light, means that recording starts.
