ARC System 2

When I open the measurements set on my ARC 2 Plug-In and turn the cor-

rection ON, the resulting sound and the displayed response is strange and

incorrect, making the monitors sound worse than when ARC 2 Plug-In is not

enabled. Do you have any suggestions?

Please check if the ARC 2 Measurement Microphone is working, by

connecting the microphone to a +48V phantom microphone preamp

and listening to it through headphones. The microphone should exhibit

a neutral, clean sound. If the microphone is not working, producing

loud noises, or having a very weak output signal, please contact IK

Multimedia Technical Support.
