Setup In dicators
Impact control and indicators: Press the Impact control to add midbass
punch to the sound (such as the fullness of drums or the upper frequencies
of a bass guitar). The impact setting may also affect the sound of male
vocals. The indicators show the setting.
Bass control and indicators: Press the Bass control to boost the bass
(such as low-frequency sounds from bass guitar and bass drum). Two levels
of bass boost are available. The indicators show the setting.
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.
Defeat button: The Defeat button turns off all of the MS-2’s EQ,
processing and user settings, passing audio unchanged to the output. This
lets you compare the sound with and without the MS-2’s processing. When
Defeat is active, the Treble, Impact, Bass and Image indicators all turn off.
Input indicator: Lights green when audio connectors are inserted and the
input signal level is OK; lights red when the output level of the connected
portable media player is too high. See Setup and Use, on this page, for
more information.
Sub indicator: Lights green when you have set up the MS-2 for use in a
system with a subwoofer. See Using the MS-2 with a Powered Subwoofer,
on page 5.
Treble control and indicators: Press the Treble control to increase
or decrease the level of the treble (such as high frequency sounds from
cymbals or the sound of the letter “S”). The indicators show the setting.
SETUP AND USE
Until you perform a setup procedure, your MS-2 will pass the audio signal
unchanged from the connected device to your vehicle’s audio system. None
of the MS-2’s controls or processing will be active until you perform a setup
procedure.
NOTE: If you have added a subwoofer to your system, please see
Using the MS-2 with a Powered Subwoofer, on page 5, before
performing a setup procedure.

DISTRACTION WARNING: Do NOT perform the setup procedure while
driving. We recommend that you perform these functions only after
pulling off the road into a position that you are absolutely sure presents
no risk. Always obey all traffic laws while driving.
Setup Procedure:
1. Connect the MS-2 as shown in the Connections section on page 2.
2. Enable your vehicle audio system’s “Aux” (or MP3) input.
3. Set your portable audio player’s volume level to 3/4 full or higher and play
music on it. The MS-2’s input indicator should light green. If the input
indicator flashes red, turn the volume of your portable player down until
the red light stops flashing and remember the setting.
This is the volume
control setting you should use on your portable player while using the MS-2.

4. Adjust your vehicle audio system’s volume control so the music is playing
at a comfortable volume level. Adjust the front/rear fader control so that
the sound comes mostly from the front speakers but so you can still hear
some sound from the back. You can readjust this after setup.
5. As you sit in your vehicle’s driver’s seat, hold the MS-2 directly in front of
your face, about 6 – 8 inches (150mm – 200mm) away.

6. Press and hold the Setup button. The Setup indicators will flash one at
a time and you will hear brief test signals through your audio system’s
speakers. IMPORTANT: Do not move the MS-2 while the test signals
are playing.
7. Keep holding the Setup button until one of the three Setup indicators
remains lit, showing the setup results:
• OK: Setup has been completed successfully.
The MS-2’s DSP equalization and time
correction processing is now active.
• High: Your vehicle audio system’s volume
control was set too high during the setup
procedure. Lower the system’s volume and
repeat steps 5 – 7.
• Low: Your vehicle audio system’s volume

control was set too low during the setup
procedure. Raise the system’s volume and
repeat steps 5 – 7.
You can repeat the setup procedure at any time. For example, if you want to
re-tune the system for a different listening position, simply repeat steps 5 – 7
while sitting in the new location. If you want to use the MS-2 in a different
vehicle, you will need to repeat the entire setup procedure (steps 1 – 7).
Using the MS-2 with a Powered Subwoofer:
1. Press and hold the Bass button for five seconds.
The Sub indicator light will turn on.
2. Set your subwoofer’s crossover
(low-pass filter) to 50Hz.
3. Turn your subwoofer’s volume control
down until you can barely hear that the
subwoofer is playing while you’re seated

Standby and On Modes
The MS-2 will automatically enter Standby mode whenever no control
buttons have been pressed and an audio signal has not been present for
approximately five minutes. All indicators will be off and the Power indicator
will pulse red. The MS-2 will automatically turn on whenever an audio signal
is present at its input or whenever you press any control button.
You should disconnect the MS-2 from the power supply if you will not be
driving the car for a week or more.
Setting the System Volume
For the best audio performance, set your portable music player’s volume
to the same level it was during the setup procedure, and use your vehicle
audio system’s volume control to adjust the volume.
Adjusting the Sound
Press the Treble, Impact, Bass and Image buttons to fine-tune the sound to
your personal preference. The indicators next to the buttons will show the
settings.
Setting Memory
The MS-2’s settings are stored in flash memory, and will remain
indefinitely when the MS-2’s power connection is removed.
4. Perform the MS-2’s setup procedure as directed on page 4.
5. When the setup procedure is completed, readjust your subwoofer’s
volume control to suit your preference. Then, use the MS-2’s adjustments
to further fine tune the sound.
If you want to perform a setup procedure again, follow the steps above again
before doing so.
If you want to use the MS-2 in another system that doesn’t include a powered
subwoofer, press and hold the MS-2’s Bass button for five seconds to return
it to normal operation. The Sub indicator light will turn off.
