About this deal

In this application note, we will show you how to design an active 2-way loudspeaker with the miniDSP 2x4 HD/Flex. Using the 2x4 HD/Flex, you can either create a conventional (Linkwitz-Riley or Butterworth) crossover, or a linear phase crossover. MiniDSP is pleased to introduce the UMIK-2, its second-generation omni-directional acoustic measurement microphone. The UMIK-2 has everything that made the first-generation UMIK-1 one of our best selling products, including a convenient plug-and-play USB connection and a unique calibration file for each microphone to ensure accuracy.

In addition to Dirac Live, the miniDSP SHD includes a full suite of our powerful but user-friendly DSP audio tuning software - ten-band parametric EQ per channel, crossovers up to 48 dB/octave, compressor/limiter, and a flexible 2x4 matrix mixer — for powerful audio system tuning in applications ranging from subwoofer integration to a two-way active speaker. Hardware FeaturesFRANCE:ShowRoomAudio, créateur de solutions audio professionnels : Conseil, vente de matériel, études acoustiques et fabrication de meubles de studios. INDIA: Avenue Sound specializes in performing custom installations and integrations of Audio/Video and Home Automation Solutions for Residential, Commercial and Marine Landscapes.

For stereo system (e.g. 2ch dirac live, single speaker measurement), use the 0deg file and point the UMIK-1 at the speakers With multiple digital inputs and eight unbalanced analog output channels, the miniDSP Flex Eight can implement active speakers up to stereo four-way. Flexible 2x8 signal routing supports many other configurations such as two-way, three-way and multiple subwoofers. As always, a full suite of miniDSP’s tried and proven audio processing functionality is included: FIR filters and parametric EQ on the input channels, and parametric EQ, crossovers, advanced biquad programming and delay on each output channel.The miniDSP SHD Audio-Streamer is a high-end signal audio processor offering user-friendly DSP solutions, DiracLive® audio calibration, and an embedded network audio streamer. With Roon streaming technology and a certified Roon Ready network player, it ensures a remarkable user interface, reliable performance, and uncompromising audio quality. Also, discover the brand's other Dirac Live devices, such as the miniDSP SHD, miniDSP SHD Studio and the miniDSP SHD Power. The SHD series combines Dirac Live with the popular Volumio streaming platform and the SHD power, even with integrated amplifiers.

REW: miniDSP worked along with John Mulcahy to develop even greater compatibility for the UMIK-1 inside REW! With the latest beta release of REW (v5.01 and up), the UMIK-1 is automatically recognized by the software and prompted for use when REW is started with the microphone plugged in.Note: To use Roon, you will need to have a paid account with Roon Labs. Your miniDSP SHD Series includes a free two-month tria Please look at the power supply table in our replated blog post to see which power supply to choose for the DSP module.

Optional upgrade to Dirac Live® 3.x Digital Room Correction, Stereo Full Range Room Correction (20~20kHz)For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-1 at the ceiling. Recommended by our Friends The SHD has extensive connectivity options. Three digital inputs, two analog inputs and USB Audio enable the SHD to fit right into any modern audio system. The four-channel DSP-controlled outputs are available as single-ended (RCA) and balanced (XLR) analog as well as SPDIF digital. OK, I was not ready for this. A multifunction device with DSP that has a SINAD (relative sum of distortion and noise) to rival and outperform many dedicated DACs? Amarra Symphony: Amarra Symphony with IRC is an advanced music file player for the Apple Mac platform. It includes a feature called "Impulse Response Correction" (IRC), that corrects for acoustical errors at the listening position caused by early reflections from the speaker and listening room. It also provides the ability to tailor the response at the listening position using target curves. SWEDEN: The team @ Hembio Butiken has a wide range of miniDSP platforms. A great choice for all our Swedish customers!
