First off the meat and potatoes of an audio mixer, the preamp. It is not the beefiest one, but the 50 dB gain it provides when the microphone type switch is toggled to “dynamic” is neither the humblest nor on par with the basic models from Behringer or PreSonus.
We do not cut corners on the mic jack either, which is a combo jack allowing XLR and TRS balanced microphone input. Unexpectedly, the 48V phantom power comes as a standard for the XLR input. But if you are also looking for an instrument input, this SC3 might not be the ideal choice, instead, we have the recording mixer out there for you.
The same story can be found on the 3.5mm monitoring jack, you can comfortably use it with a pair of high-impedance (up to 250 ohms) headphones. You might not need such high-fidelity headphones for gaming, especially since not every gamer would like to enable the sidetone, but it is just good to know that your device can drive one of those high-end gear.
