Image control and indicators: For music to be accurately reproduced
and seem as though it comes from musicians spread out across the
dashboard instead of from only the speaker nearest you, the sound from the
left and right speakers must arrive at your ears at exactly the same time. To
achieve this, the MS-2 includes digital time correction (enabled in the Image
control’s “On” setting). If your car’s audio system already includes “DSP”
or surround sound processing, you should set the MS-2’s Image control
to “Off,” but you can choose the setting that sounds best to you. The
indicators show the setting.
