Description

Introducing the long-awaited “reboot” of miniDSP’s best-selling 2x4 digital audio processor: the miniDSP 2x4 HD! This tiny powerhouse is jam-packed with miniDSP’s tried and proven audio processing functionality: flexible para- metric EQ, Butterworth and Linkwitz-Riley crossovers, advanced biquad pro- gramming, and delay on each output channel. miniDSP’s “one hardware many plugins” concept allows for many interesting future applications! The upgraded on-board 400 MHz Analog Devices SHARC processor also ena-bles substantial processing upgrades previously available only on more ex-pensive platforms, such as 96 kHz internal processing for true high-resolution audio capability and assignable FIR filter taps for sophisticated equalization, crossover, and room correction capabilities. All to be accessed and programmed with miniDSP’s easy-to-use interface software. I/O capabilities get an upgrade too, with the addition of USB audio streaming up to 192 kHz and a TOSLINK digital input. The miniDSP 2x4 HD will find application in full-sized hifi and home theater systems, on desktops, in cars, in recording studios — anywhere a compact, simple, yet surprisingly powerful DSP audio processor is needed.

    • NOTHING ELSE SIMILAR IS AVAILABLE AND IT WORKS WONDERFULLY!!!!
If you have discovered this amazing device, have a use in mind and think you might somehow find a reasonable alternative that is not a POS designed for bad automotive audio then save yourself time and effort and buy it now! I questioned and researched for over a year to find nothing comparable. I found need for a miniature "little black box" multi-channel digital sound processor to use for with the accompaniment system of my player grand piano. My belief that it would be very easy to find because essentially the same circuitry is included in today's "basic" devices was utterly incorrect! My smallish town in the mid-west still--amazingly--has a true "hi-fi" store and even their salesman I've known since the 80s gave me a blank stare when asking about a miniature digital sound processor. My application requires only the basic functions of output channel equalization and input parametric equalization. My audio source is monophonic but the 2x4 nature allows completely independent adjustment of the two input channels which allows separately tailored parametric EQ from the inputs to be applied to the four independent outputs. One input channel has a parametric curve optimized to the single subwoofer channel in its proper space just ahead of the rear leg of the piano with the instrument itself diagonally spaced in the purposely designed band area of a very large room on the lower floor of a big ranch home. The second input channel has very little general parametric EQ but highly tailored EQ curves driving three channels that I call "presence," "depth" and "ambiance" all of which are either very carefully attached to the instrument or directly beneath on the heavy wool Oriental of the sort I consider an absolute sonic necessity outside of a carefully designed concert hall. I've been building and working with audio equipment all of my life and this is the most useful and smooth sounding device I've experienced since my first Heathkit Pro Series component (the awesome preamplifier) c. 1984. Certainly not cheap but considering I paid over $1,000 for a Yamaha DSP-1 in the 1980s it is a fantastic value. Since my system is fully contained to and beneath a physical musical instrument I have absolutely no reason to use the delay and other advanced features. If anything however I somewhat regret not buying the 4 x 8 version. Despite my monophonic input I'm operating six loudspeakers to include two pairs. My corner location has 30' or so of mirrored wall on one wall and another of wood and stone. With a couple more channels I could attempt to play some sonic games to reinforce what I can only call the sonic holograms that find performers I have heard in real life literally in the house. It's the sonic extasy I've sought all my life but never thought I could achieve--much less afford. Yoga beneath the treble section is sublime. Programming via the supplied software is simple and intuitive. The device itself contains the programming instructions for three (at least) system-wide settings that can be changed without direct connection to the computer. I had a problem with the first unit as it utterly refused to maintain connection to my older but top-of-the-line HP laptop. Service and communication was SUPERB! They replaced the original after truly good communication over a few days which seemingly eliminated the computer as the problem. The replacement still experienced communication failure but only rarely--think tens of minutes instead of rarely more than ten seconds--and I was able to properly transfer my settings (created off-line). Very shortly after I got a new laptop (Acer Nitro) and there has never been another communication failure. Operation over the last six months or so has been flawless. I have things power protected but this has been a CRAZY year for storms in southeastern Missouri and the power has experienced numerous "blip outs" and spikes. ... show more

The miniDSP is an amazing audio device that has allowed my Jamo S808 subwoofers to play in tandem with my Kali IN-5 studio monitors. After experimenting with multiple crossover filters and slopes, I finally settled on the mellow roll-off 24db/octave Linkwitz-Riley crossover filters. The revised filter settings allow my Jamo subs to blend perfectly with the Kali's without drawing attention to themselves. The miniDSP offers four presets that can be instantly reconfigured as desired, and once saved to the internal memory of the miniDSP, the presets are available via the (included) remote control. I have used the miniDSP both as a dedicated subwoofer crossover and as a high pass crossover for the Kali's. I did notice a slight loss of resolution with the miniDSP in the signal path vs. running the Kali's directly from the balanced outputs of the Fiio K9 AKM dac/preamp. This is largely due to the superior power supply, dac and analog section in the Fiio. I began to wonder if there was untapped potential waiting to be unleashed from the miniDSP. After doing some research I concluded a high quality linear power supply would be the most logical upgrade path to pursue. I purchased a Fiio/Jade Audio PL-50 (2023 version) linear power supply and aftermarket OCC copper dc umbilical cable. After just a few hours of use, I was stunned at the improvement in sound I was hearing from the miniDSP. I hear increased resolution with a deeper soundstage and zero noise of any kind. Bass impact is amazing now. EDM tracks have never sounded this good on the Kali's. It seems the Fiio PL-50 is the key to unlock the full potential of the miniDSP. You can clearly see in the picture I uploaded how massive the PL-50 linear power supply is vs. the miniDSP's stock wall-wart ac power adapter (sitting inside the copper umbilical cable). I am totally happy now and no longer perceive a slight loss of resolution when running the Kali's directly from the miniDSP's rca analog outputs. The extra $160.00 cost of the PL-50 and OCC umbilical cable is a no-brainer if you seriously want to elevate the performance of the miniDSP 2x4HD. ... show more

    • One of the best audio purchases you can make.
One of the best buys in hifi. Everyone with a desktop music system should get one. The possibilities with this device are endless. Great performing Dac? Check. Parametric EQ? Check. All kinds of inputs, easy to use software, can be used with REW for room equalization (if you have a calibrated measurment mic). All that and all of the cool setups you can use this for. High pass filter your main speakers and have 2 stereo subwoofers, with eq for your room. Custom build your own speakers and use this as an active 2 way crossover. Eq your computer speakers and eq your headphones on a seperate amplifier. This product for what it does is in a league of its own for the price. ... show more
