About the Flex
The miniDSP Flex is a versatile, compact digital audio processor designed for high-fidelity stereo and multi-channel applications. It features a 32-bit floating-point 400MHz SHARC DSP, supporting a wide range of digital and analog inputs (USB, S/PDIF, TOSLINK, Bluetooth LDAC/aptX HD, and analog RCA or balanced TRS, depending on version). The Flex offers flexible input/output routing, parametric EQ, crossovers, FIR/IIR filtering, and delay on each output channel, making it ideal for subwoofer integration, active speakers, and room correction. An OLED front panel display and encoder knob provide intuitive control, and the device can be upgraded with Dirac Live room correction for advanced acoustic optimization. Its audiophile-grade performance and compact form factor make it a centerpiece for modern HiFi systems.
