Alto True Mix 600

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.
