Alto Professional TrueMix 500 Mixer – A Versatile Tool for Audio CreatorsDo you need a compact device that connects your microphone, instruments, and computer into one cohesive system? The Alto Professional TrueMix 500 is a portable analog mixer with a built-in stereo USB interface, providing all the essential features for home recording, live streaming, podcasting, and stage performances.

Product FeaturesThe device is equipped with five analog inputs featuring high headroom circuitry, which translates to minimal noise and no signal clipping even at high volume levels. The microphone channel offers an XLR input perfect for connecting dynamic microphones, as well as a balanced ¼" TRS line input designed for instruments and other line-level sources. Two additional stereo channels are equipped with dual balanced TRS inputs, ideal for line-level sources.

Each channel features a two-band graphic equalizer with color-coded knobs – red for low frequencies and blue for high frequencies – enabling precise sound shaping even in dim stage lighting or studio conditions. Locking buttons ensure setting stability during transport.

Professional Connectivity and Flexible RoutingConnecting the TrueMix 500 to a computer is incredibly fast thanks to the plug and play functionality, which works seamlessly on both Windows and macOS systems. The two-channel USB interface allows for sending stereo signals to the computer and playing audio from the computer back into the mixer.

The routing system offers flexible signal direction options. The 2-track inputs can be assigned to the main mix output or routed directly to the headphone output. The main output uses balanced TRS connectors with a maximum level of +22 dBu, while the headphone output delivers 160 mW at 32 ohms impedance, allowing for comfortable monitoring with various types of headphones.
