        Product details

        2x4 FLEX DSP audio processor | Unbalanced (RCA)


        The miniDSP Flex is the 3rd generation of our popular line of compact 2-in, 4-out audio processors. It retains the powerful floating point processor but rethinks the I/O architecture so we can provide our customers with different input-output versions in this compact chassis. The initial versions are single-ended analog I/O (RCA), balanced analog I/O (TRS) and digital out with superb audiophile specification for your enjoyment. 


        All versions include a set of digital inputs: USB audio, S/PDIF (RCA/optical) and Bluetooth (LDAC/aptX). An OLED front panel display and volume control/encoder knob provides easy control. As always, the Flex series is jam-packed with miniDSP’s tried and proven audio processing functionality: flexible parametric EQ, IIR & FIR filters, crossovers, advanced biquad programming and delay on each output channel. Last but not least, all platforms are easily software-upgradable with Dirac Live®, the world’s premiere room correction system for full range (20~20kHz) tuning.


        The miniDSP Flex will find a myriad uses in applications ranging from a compact digital stereo preamp through subwoofer integration and optimization to active speakers, home theater and recording studios. You just need to let your creativity do the rest!

        Note: This product comes with a coupon (€9,50) for one free miniDSP plugin download.

        Pretty good, as long as you have your streaming/sources sorted. I just wanted some EQ.
