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 provides all the essential features you need for home recording, live streaming, podcasting, or performance. TrueMix 600 features a dedicated Bluetooth channel for easy streaming from your personal devices. The Bluetooth channel also supports feedback-free phone pairing using Mix-Minus technology. This feature is not supported by other audio mixer series in this class. It has 6 analog inputs with high headroom circuitry to minimize noise and clipping in the signal. The microphone input channel features an XLR input, perfect for connecting dynamic or condenser microphones with 48V phantom power. These channels also feature 1/4-inch balanced line inputs for connecting instruments or other line-level signals. There are also two stereo input channels, each with two balanced 1/4-inch TRS inputs. These inputs are ideal for line-level audio sources. All channels feature a 2-band EQ with color-coded controls, making it easy to dial in the perfect sound, even in low light. Connecting the TrueMix 600 to your computer is also very fast, thanks to plug-and-play connectivity on Windows and macOS. The TrueMix 600 is a compact, feature-packed audio mixer perfect for on-the-go use. Robust Output Routing Whether you're creating music at home, recording a podcast, or live streaming online, being able to hear your voice is essential. TrueMix 600 has a variety of output and routing options to suit any scenario. There are two headphone outputs, each with independent volume controls. If you need to send the audio signal to another destination, such as an external effects processor, there's an AUX send/return and individual AUX send controls on each channel, so you can always tweak the perfect mix. For recording, the USB output sends a copy of the main output to your computer, or you can also connect the 2-track in/out to an external recorder and send it directly to one of the headphone outputs. TrueMix 600 provides everything you need for complete control over your audio routing.
