TSM321 / (FX)

Right at the core of Prosonar’s “Turntablist” series, the 3-Channel format presents the essence of what most DJ’s need whilst the TSM321 is the budget choice in this class. Coming with three stereo inputs out of which one can serve as a microphone input, with all inputs equipped with gain control and 3-band Kill EQ, this unit offers further flexibility by means of its assignable and front-detachable crossfader. A comprehensive prelistening section and two master outputs, one of them balanced, complete the feature set of this unit. Unlike other mixers of its class, the TSM321 sports an internal power supply, making it superior in audio dynamics to most of its competitors. This model is also available with additional DSP effects processor as TSM321FX.

FX Version

The TSM321FX adds a sophisticated digital effects processor to the proven feature set of the TSM321. The DSP-based processor is specifically developed for DJ applications and allows to set the time basis for applicable effects by tapping along the music, plus to set the chosen effects’ intensity with a further rotary control. The 8 available effects do not only include the popular Flanger/Phaser effects, but also stunning modulated HighPass and LowPass filters and a StutterGate. This allows for a great variety of truly useful, beat-matching, DJ-focused effects.
