The room is 30 cubic metres – small to medium by modern standards (they’re all shrinking!). The tests are made in a professional control room with bass trapping/resonant absorbers and wideband absorbers built into the walls, and quadratic diffusers behind the monitors. The monitors are fed with a Lavry DA10 converter via a Mackie Big Knob for volume control.

The measurement mics are recorded through a Focusrite ISA828, the most transparent preamp in ourstudio, and the AD conversion comes via an Antelope Audio Orion 32 interface. The iPad app NeumannControl controls the monitors’ DSP features but we don’t use that for our tests. The group test is carried out with a pair of Neumann KH 80 DSP 2-way active nearfield monitors. The XREF mic is supplied with a serial-number-specific calibration file that can be downloaded for use in other products, in this case TRACT and Dirac Live. We test ARC 3 with the MEMS measurement microphone it’s supplied with, while the others were set up using Sonarworks’ XREF 20 microphone.
#DIRAC LIVE 3 SOFTWARE#
We’re using four room-correction software products as part of our group test: IK Multimedia ARC System 3, Sonarworks Reference 4 Studio Edition, Dirac Live and Waves TRACT. The resulting map or profile can be used to create compensatory EQ curves and phase shifts. Room-correction software can take measurements from various points in a room and assess how the amplitude and phase shift of discrete frequency bands compare before and after exiting a monitor system.
