The miniDSP 2x4 is a pocket size Digital Signal Processor (DSP) with two analog inputs, four analog outputs. Typically connected between your analog source (CD&DVD player/AVR/PC…) and a multi-channel amplifier, the embedded DSP algorithms allow for a wide range of tuning applications.

MiniDSP 2x4, a low cost Digital Signal Processor for audio applications. Great sound in a tiny package. The miniDSP 2x4 in a box is a flexible pocket size DSP processor with 2 x analog IN, 4 x analog OUT. Combined with a plug-in software for programming, one can configure the on board Audio processing filters real time from a PC or Mac environment. Once the board configured, the device operates standalone and doesn't require a computer anymore. For more information on potential applications, please check the application section of our website.

May it be subwoofer tuning, multi-way crossover or even equalization of your stereo system, the 2x4 strength lies in its ease of use and flexibility. Based on a Hardware + Software combination, one tunes the system from a userfriendly software on PC/Mac machine. The configuration from the driverless USB connection is live, real time and a one time requirement. All settings are automatically stored and reloaded at subsequent boot up. Thanks to 3rd-party tuning software like Room EQ Wizard and our USB measurement microphone (UMIK-1), the miniDSP 2x4 makes audio tuning easy. Join our large community of audio enthusiast and start enjoying the potential of this powerful audio processor.
