Alto Professional TRUEMIX 500

3-Channel Analog Mixer

The TrueMix 500 from Alto Professional is a compact mixer, with a small footprint (159.5x193x66mm) and weighing only 900 grams, designed to ensure maximum portability. Equipped with an integrated stereo USB audio interface, the Alto TrueMix 500 offers all the essential features for home recording, live streaming on Youtube, Twitch, and Facebook, podcast creation, small live performances, and for use with the most common audio/video communication platforms: Teams, Zoom, Skype, etc.

Circuits and components offer pleasant dynamics, as noise is minimized and signal clipping is well manageable thanks to the high headroom. Channel 1 offers an XLR input with microphone preamplification, which supports both dynamic and condenser microphones thanks to the presence of 48V phantom power. This mono channel also offers a balanced line input on a ¼" TRS jack, to which you can connect instruments such as electric guitars or basses, or other line-level signals: synths or other monaural sources. There are two stereo channels, each with a pair (L and R) of balanced ¼" TRS jack inputs. These inputs are perfect for your line-level audio sources. Gain, Pan, rotary volume control, peak indicator, and a two-band equalizer are available on all three channels: ±15dB @ 12kHz for highs, ±15dB for lows fixed at 80Hz.
Connecting the Alto TrueMix 500 to your computer, smartphone, or tablet is simple and immediate. As it is a class-compliant device, connectivity with Windows and macOS operating systems is truly plug and play and does not require drivers. The TrueMix 500 is your perfect companion for mixing, audio recording, and live streaming even when you're on the go.
