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 easily 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 48v 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.

Robust Output Routing

Whether you’re making music at home, recording a podcast, or livestreaming online, being able to hear yourself is essential. The TrueMix 600 features a variety of output and routing options to handle any scenario. There are two headphone outputs, each with their own independent volume control knob. If you need to send your audio signals to another destination like an external effects processor, there is an AUX send/return and individual AUX send controls on each individual channel so you can always dial in the perfect mix. For recording, the USB output sends a copy of the main outputs to your computer, or you can connect the 2-Track in/out to an external recorder which can also be sent directly to one of the headphone outputs. The TrueMix 600 delivers everything you need to take full control of your audio routing.
