The MiniDSP 2X4HD interface is a processor for digital filtering. It uses a 24 bit / 48kHzDAC (digital / analog converter) & asynchronous USB Audio Class 2.0 input. Like many other miniDSP devices, 2x4 provides powerful, accessible tools to implement a digital filter (IIR Butterworth / Linkwitz Riley 6 to 48dB) and a parametric equalizer. It will suit audiophiles who want to set an effective correction on a pair of stereo speaker. The device can also be used to manage multiple subwoofers in a home theater setup.

In addition to its digital input, the 2x4 in miniDSP has a stereo analog input on phoenix connector for connecting another Hi-Fi device with analog output. Such as a turntable via a RIAA box, or any other analog source. It is a great accessory to centralize the whole installation on a single pair of speakers, while enjoying a correction / filter that extends to the entire chain.

Audio processor

The 2x4 features a 28 / 56bit floating-point Analog Devices audio processor. The latter allows digital audio calculations as well as control via the USB interface in real time.

The MiniDSP 2X4 provides a complete solution with USB & analog inputs, filtering and parametric EQ.

Integrated version

This module also exists in a ready-to-use / stand-alone version (already mounted in a metal housing). You may find the non-DIY version by following this link.
