miniDSP Flex: Audio processor based on ADSP21489

miniDSP Flex is a 3rd generation 2-in/4-out audio processor. It retains the powerful floating-point processor used previously and redesigns the I/O architecture to provide flexible connectivity. This version features single-ended stereo RCA inputs and outputs, as well as a full panel of digital inputs with Bluetooth, USB-B, coaxial and Toslink optical.

The OLED display on the front panel and volume control make it easy to operate the device. Of course, the Flex series includes powerful audio processing features developed by miniDSP: flexible parametric EQ, IIR and FIR filters, crossovers, programmable bi-quad filter and delay for each output… In addition, all systems can be software enhanced using the Dirac equalizer Live® for precise tuning across the entire frequency range.

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