Outboard DSP: Marani Pro MIR260A

The third of a series of product reviews of outboard DSP hardware, this article explores the MIR260A DSP processor from Marani Pro Audio. Supported with expert measurements performed by Charlene Chow on a flagship APx555B analyzer (courtesy of Audio Precision), Vance Dickason looks at this professional DSP processor with two inputs and six outputs, and a more cost-effective model from Marani.

In his exploration of available Outboard DSP systems, Vance Dickason explores the Marani Pro Audio MIR4801, the company's flagship DSP processor with four inputs and eight outputs. MIR stands for Marani Impulse Response, which refers to the proprietary Marani linear (zero) phase Linkwitz-Riley filter, which is described in a whitepaper titled by Michael Marani and Simone Castrucci, both from SEED Electronics, Guangzhou, China.

In this December 2024 issue there's a new DSP product review of the Marani Pro Audio MIR260A outboard processor, and Lars Risbo shares his expertise in Numerical Optimization applied to Speaker Box Alignments. Essential resources are the updated directories of Test and Measurement and of Simulation and CAD Software vendors. On Test Bench, Vance Dickason characterizes the Faital Pro HF110 1" Neodymium Motor Compression Driver and the SB Acoustics Satori MR16TX-8 6.5" TPCD Midrange.

In this issue of Voice Coil, Vance Dickason continues his exploration of Outboard DSP systems with a review of the Marani Pro MIR4801 Audio System Processor. And Claus Futtrup explores the concept of a transitional alignment between B4 and LR4. Next, Mike Klasco writes about new materials for cabinets and enclosures. On Test Bench Vance Dickason characterizes the new B&C Speakers DE640-16 1.4" compression driver and the latest Satori MR13TX-4 5" TPCD TeXtreme midrange from SB Acoustics.
