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!

Understanding LDAC Wireless Audio

LDAC™ is Sony's High Quality wireless audio streaming and we at miniDSP thought it would be great to showcase its benefits. By nature, Bluetooth audio streaming is very convenient but it's not without its limitations and until recently has not been an audiophile experience. LDAC is a new CODEC enabling 3 x the data to improve your enjoyment. You can read more on the Sony LDAC™ page
