Portable Analog Audio Mixing with the Power of Bluetooth:

- The Alto Professional TrueMix 600 is a portable audio mixer with Bluetooth and a built-in stereo USB audio interface that delivers all the essential features you need for home recording, livestreaming, podcasting, or performing. The TrueMix 600 features a dedicated Bluetooth channel for easy streaming from your personal devices. The Bluetooth channel also supports feedback-free phone pairing by utilizing mix-minus technology, a feature that no other audio mixer series in this class supports. There are six analog inputs with high-headroom circuitry for minimal noise and clipping in your signal. The mic input channels offers XLR inputs that are great for connecting dynamic mics or condenser mics with 48 V phantom power. These channels also have balanced ¼” line inputs 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 while operating in low-light situations. Connecting the TrueMix 600 to your computer is also lightning-fast, with plug-and-play connectivity on Windows and macOS. The TrueMix 600 is a feature-packed compact audio mixer that’s perfect for using on-the-go.
