The miniDSP 2x4 kit is a low cost, low power DIY Digital Signal Processor (DSP) board with two analog inputs and four analog outputs. Typically connected between your analog source and a multi-channel amplifier, this pocket size module packs all the filter tools you need to get started with tuning your 2 way or 4 way subwoofer.
At the core of the miniDSP 2x4 kit solution is the combination of intelligent onboard firmware combined with the miniDSP flexible software plug-in. May it be a PC or Mac, the first step will involve programming the device over the driverless USB 2.0 port. Using the onboard Digital Signal Processor (DSP), you can configure the onboard parametric/graphic equalizers (PEQ), crossovers, levels and time alignment in real time. All settings are automatically stored and reloaded at boot up.
