TEST AND TUNE
SETTING THE GAIN:
WITH THE SYSTEM FUNCTIONING PROPERLY, FOLLOW THESE STEPS TO SET THE GAIN CONTROL:
1.
TURN THE GAIN CONTROL(S) ALL THE WAY DOWN (COUNTER-CLOCKWISE).
2.
TURN THE KEY TO THE ACCESSORY POSITION, AND THEN TURN THE SOURCE UNIT ON.
3.
SET ALL TONE (BASS, TREBLE) AND EQUALIZATION CONTROLS (BALANCE, FADE) ON THE
SOURCE UNIT TO “FLAT” OR “0”, AND TURN OFF “LOUD” OR “LOUDNESS”. IF A SEPARATE
EQUALIZER IS USED, DISABLE OR SET ALL OF IT’S CONTROLS TO “FLAT” OR “0”.
4.
WHILE PLAYING A STANDARD NON-MP3 CD
1
, SET THE SOURCE UNIT’S VOLUME CONTROL TO
75% OF MAXIMUM LEVEL.
5.
SLOWLY INCREASE TO GAIN CONTROL UNTIL YOU HEAR A SLIGHT
DISTORTION OF THE AUDIO PLAYBACK. THIS SHOULD RESULT IN THE
TYPICAL RANGE.
WARNING: SETTING THE GAIN TOO HIGH IN AN ATTEMPT TO GET “MORE VOLUME” CAN NOT ONLY CAUSE PREMATURE
DISTORTION, BUT CAN ALSO DAMAGE YOUR SPEAKERS. IF YOUR SYSTEM CONFIGURATION RESULTS IN YOUR GAIN
CONTROL BEING SET OUTSIDE THE TYPICAL RANGE AS INDICATED ABOVE, CALL US TO RESOLVE THE PROBLEM.
SETTING THE CROSSOVER:
WITH THE SYSTEM FUNCTIONING PROPERLY, FOLLOW THESE STEPS TO SET THE CROSSOVERS:
1.
SELECT THE DESIRED MODE FOR EACH CROSSOVER MODE SWITCH; LOW
FOR LOW-PASS MODE OR HIGH FOR HIGH-PASS MODE (DEFAULT).
NOTE: IF THE DESIRED MODE IS FULL FOR FULL-RANGE, CHANGING THE CROSSOVER
FILTER CONTROL WILL PRODUCE NO EFFECT IN THIS MODE.
2.
SET ALL TONE (BASS, TREBLE) AND EQUALIZATION CONTROLS (BALANCE, FADE) ON THE
SOURCE UNIT TO “FLAT” OR “0”, AND TURN OFF “LOUD” OR “LOUDNESS”. IF A SEPARATE
EQUALIZER IS USED, DISABLE OR SET ALL OF IT’S CONTROLS TO “FLAT” OR “0”.
3.
WHILE PLAYING A STANDARD NON-MP3 CD
1
, SET THE CROSSOVER FILTER
ADJUSTER TO THE DESIRED FREQUENCY (150HZ OR ABOVE DEFAULT).
NOTE
1
: THIS IS THE PREFERRED AUDIO TESTING SOURCE METHOD, AS MP3, XM, FM, AND AM ALL HAVE SOME LEVEL OF
COMPRESSION OR DEGRADATION INVOLVED, WHICH CAN LEAD TO VARYING RESULTS. IF THE PREFERRED METHOD IS
NOT AVAILABLE, USE THE MOST COMMON PLAYBACK METHOD YOU USE WHILE RIDING.
