USING THE MS-8
The arrow indicates the selected band; the band’s center frequency is indicated
on the left side of the screen; the amount of boost or cut that you apply is
indicated on the right side of the screen.
Use the Left and Right navigation buttons to select the frequency band you want
to adjust, and use the Up and Down navigation buttons to make the adjustments.
Each press of an Up or Down button changes the level by 0.5dB. As you apply
boost or cut, the selected band will increase or decrease in size on the screen to
indicate the relative change in level.
IMPORTANT: The MS-8’s digital volume and equalization work differently
than standard analog controls. Boosting the MS-8’s subwoofer-level

Logic 7: Logic 7 technology creates an ideal 5.1-channel or 7.1-channel
surround-sound listening environment from two-channel source material. Logic
7 processing widens the stereo soundstage and increases the sense of sonic
envelopment, making the vehicle’s interior boundaries seem to disappear. The
music sounds as though it exists on its own, rather than coming from speakers.
We have specically tuned the MS-8’s Logic 7 for use in vehicles. It includes
processing for the center-channel speaker (if one is present in the vehicle’s
system).
You can turn Logic 7 on and off by pressing the Select button while Logic 7 is
highlighted in the Audio Controls menu.
Processing: The Audio Controls Processing option activates and defeats the
MS-8’s digital time-correction and acoustic-equalization circuitry. Using the
Select button to switch between Active and Defeat will let you hear how the
MS-8’s advanced digital signal processing dramatically improves your system’s
performance.
Seat: You can optimize the sound for any of the seating positions that you
measured during the setup process. Pressing the Select button cycles through
the available positions: Driver, Passenger, Front, Rear, All. “Front” or “Rear”
optimizes both front seats or both rear seats as the preferred listening position.
“All” is a general setting that will produce good sound for any seating position.
