When connecting an analog mixer with standard outputs with your recording devices, make sure that your mixer is powered off and set master and channel faders all the way down (or just press standby if it has that option). Find master outputs on your mixer, inputs on your sound card and determine what kind of cables you need to connect these two devices.
