Using this Behringer Xenyx 1202 SFX mixer is a breeze. First, connect your audio sources to the 12 inputs. If you're using a high - end studio microphone, make sure to turn on the 48V phantom power from the XENYX microphone preamps. To connect it to your computer or mobile device, use the stereo USB audio interface. For some cool sound effects, choose from the 100 presets in the Klark Teknik FX processor. You can also mix PC or gaming sounds directly into the streaming output. When it comes to maintenance, keep it in a dry and clean place. Don't expose it to extreme temperatures or humidity. Before you turn it off, make sure to lower the volume of all channels to avoid any sudden noise. And remember, handle it gently to prevent any physical damage.
