The Flex Digital miniDSP is the brand's 3rd generation 2-in/4-out audio processor. It keeps the powerful floating point processor previously used with a redesigned input/output architecture to offer versatile connectivity. This version has an unbalanced RCA stereo input, as well as a complete digital input panel with Bluetooth, USB-B, coaxial and Toslink optical. The output is made in coaxial or optical.

An OLED display on the front panel and a volume controller make it easy to control the unit. Of course, the Flex series incorporates the powerful audio processing features developed by miniDSP: a flexible parametric equalizer, IIR and FIR filters, crossovers, the possibility to program the biquad filter and delay for each output... In addition, all systems can be software enhanced with the Dirac Live® correction solution for fine tuning over the entire frequency range.

The miniDSP Flex offers a wide range of uses and applications, whether in combination with a compact digital stereo preamplifier, for integration with a subwoofer or for active speaker optimization.

MiniDSP Flex review by Audio Science Review (Amir)

" What a nice combination of functionality, usability and performance! As with many DAC companies, it is clearly Minidsp has put strong focus on chasing away sources of noise and distortion. Yes, there is some work left to do with intermodulation distortion but other than that, measurement after measurement put a smile on my face. All AV processor and receiver companies lose any excuses they have for not providing this level of performance seeing how the Flex also implements various signal processing modules. "
