As the entry-level model of Prosonar’s consumer-grade Spintec series, the CSM211 Stereo Mixer makes a difference to what a customer can expect from a mixer in this very affordable price range. Other than its competitors, this mixer has input gain controls, proper faders and a microphone tone control. To bring assistance to a perfect mix, the input levels can be displayed on the VU meter and a premix can be done on the headphones. As an extra feature, a top-panel 3.5mm TRS jack accepts input from MP3 players and alike. As an option, the CSM211 can be equipped with an on-board MP3 player to replay files from an USB memory stick instead of the 3.5mm TRS socket. There is no mixer in the market with better value for money!
