Simple-to-Use Analog Audio Mixing for Any Application
The Alto Professional TrueMix 500 is a portable mixer with a built-in stereo USB audio interface that delivers all the essential features you need for home recording, livestreaming, podcasting, or performing. There are five analog inputs with high-headroom circuitry for minimal noise and clipping in your signal. The Mic Input Channel offers an XLR input that’s great for connecting a dynamic mic. This channel also has a balanced ¼” line input for connecting instruments and other line-level signals. There are also two Stereo Input Channels, each with dual balanced ¼” TRS inputs. These inputs are perfect for your line level audio sources. All channels feature a two-band EQ with color coded knobs that make it easy to dial in your perfect sound when operating in low-light situations. Connecting the TrueMix 500 to your computer is also lightning fast, with plug and play connectivity on Windows and macOS. The TrueMix 500 is your perfect companion for no-nonsense audio mixing and recording on the go.
