Alto TrueMix 600

Alto TrueMix 600 analog audio mixer

The TrueMix 600 features a variety of outputs and routing options for any occasion. There are two headphone outputs, each with its own volume control knob. If you need to send your audio signals to another destination, such as an external effects processor, there's an AUX send/return and an individual AUX sending commands to each channel, so you can always create 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 be sent directly to one of the headphone outputs
