The Behringer XENYX Q1204USB-12-Input USB Audio Mixer is a 12-input audio mixer with an integrated USB computer audio interface. It enables you to mix together and shape the sound of multiple audio signals, and route the audio to several outputs. The mixer features four XENYX microphone preamps, 3-band "British"-style EQ, and four easy-to-use one-knob compressors.

It provides four mono channels and two stereo channels, making it suitable for small and medium-sized audio projects. There are two aux sends, which enable you to route individual channels to stage monitors or external effects, and two stereo aux FX returns. Every channel features a 3-band EQ with a swept mid, which can help you make vocals and instruments stand out in a mix. The built-in USB interface allows for a bi-directional transfer of audio to and from your computer.

The four built-in compressors are designed to simplify the process of controlling dynamics in your mix. With a single knob you can dial in the amount of compression you need for any given sound. The four XENYX preamps offer 130dB of dynamic range, and the 3-band "British"-style EQs allow you to finely tune your mix. For outputs, the mixer includes two gold-plated XLR main outputs, two 1/4" alternate outputs, and two 1/4" control room outputs. The mixer is suitable for recording studios, video editing suites, live sound mixing, podcasting and more.
