£958.53 Dirac Live

The miniDSP SHD is a DSP-based network streamer and audio processor that includes stereo (two-channel) Dirac Live room correction. It combines Roon Ready streaming with Volumio, and provides extensive connectivity (digital and analog inputs plus USB audio) and four DSP-controlled outputs. It also includes DSP audio tuning tools such as parametric EQ, crossovers, and a matrix mixer for speaker/subwoofer integration.

★ Ideal for

Yes-its built-in Dirac Live stereo room correction and DSP toolbox (including crossovers and a 2x4 matrix mixer) let you calibrate portable studio monitor setups without adding a separate room-correction computer, as long as you have the Dirac-compatible measurement microphone (UMIK-1 or UMIK-2).

Audient ORIA Mini Room Correction System and Monitor Controller
US
£183.74 ± 0.1dB (20Hz to FS/2), ± 0.2dB (20Hz to 40kHz) Sonarworks SoundID Reference

ORIA Mini is a compact hardware room-correction processor and monitor controller that sits between an audio interface and studio monitors. It uses internal DSP, supports up to four calibration profiles and works with stereo or 2.1 systems, making it suitable for home studios, project rooms and professional stereo monitoring setups.

★ Ideal for

It suits portable studio monitor room correction because its compact USB-C bus-powered design provides hardware-based Sonarworks SoundID Reference correction, four switchable profiles and support for systems up to 2.1 without relying on computer CPU or plug-ins.

miniDSP Flex with Dirac Live
US
£512.10 20 Hz - 20 kHz ± 0.1 dB Dirac Live 3.0 full range correction

The miniDSP Flex with Dirac Live is a compact 2-in, 4-out digital audio processor with USB, Bluetooth, SPDIF, optical, and analog connectivity. It suits listeners and studio users who need flexible signal routing, active crossover control, and calibrated room correction in a small desktop-friendly unit.

★ Ideal for

It suits portable studio monitor room correction because its compact 2-in, 4-out design provides full-range Dirac Live correction from 20 Hz to 20 kHz and can work with a measurement microphone.

miniDSP Flex HTx with Dirac Live
US
£700.27 20 Hz - 20 kHz ± 0.1 dB 200 kΩ balanced input; 100 kΩ unbalanced input; 300 Ω balanced output; 150 Ω unbalanced output Dirac Live 3.x full range 8-channel digital room correction

The miniDSP Flex HTx is an 8-in/8-out audio processor with HDMI eARC/ARC, USB, analog RCA and balanced TRS connectivity, configurable crossovers, bass management and parametric EQ. It suits home theater users and audio professionals building multichannel or active speaker systems who want optional full-range Dirac Live correction.

★ Ideal for

It suits portable studio monitor room correction systems because its rack-mountable design provides 8-channel processing, configurable active crossovers and full-range Dirac Live correction from 20 Hz to 20 kHz, although external monitors and a measurement microphone are required.

IK Multimedia ARC 4 System
US
£176.36 2 Hz - 45.0 kHz (-2.0 dB) 20 kOhm input, 50 Ohm output ARC 4 room correction software with phase and frequency response correction

The IK Multimedia ARC 4 System combines a compact standalone correction processor, measurement microphone, and ARC 4 software to calibrate studio monitors for a specific room. It suits home, project, and professional studios, especially setups needing zero-latency correction, adjustable correction ranges, and virtual monitor emulations.

★ Ideal for

It suits portable studio monitor room correction because its compact 144 x 120 x 45 mm standalone processor works with any monitors, stores correction profiles in hardware, and operates independently of a computer or DAW after setup.
