2-Way System Application Notes
After all the wiring connections are made and before the system is turned on for the first time, you need to make some basic adjustments. It is important that the
Setting the Crossover Frequency Controls
1.Set the crossover frequency controls to the frequency recommended by the speaker manufacturer. The following are some guidelines if this information is not available:
•Most 6” speakers will operate down to 80 - 100Hz.
•Most 5” or 4” speakers will operate down to 100 - 150Hz.
•Most 3” speakers will not operate below 300Hz.
•Most subwoofers have decreased sound quality when operated above 150Hz.
Depending upon the size of the front and rear speakers and the type of subwoofer system, fine tuning these adjustments may be required after the initial system
2.When making the high frequency adjustments, adjust the
NOTE: An exception will be when the front/rearspeakeris too small to play down to a very low frequency and the subwoofersounds distorted trying to “play up” to meet the front/rearspeaker. This may require a gap ordifference between the high and low settings. Although not ideal, this is sometimes necessary to make the system work as well as possible.
Setting the Front Output Level
Before setting front level controls, disconnect both the rear output and the subwoofer output and follow the directions below.
1.Turn the output control level to the minimum setting.
2.Turn the amplifier gain controls to the minimum setting.
3.Turn the source unit on and increase the volume until distortion is heard, then reduce volume to just below this point.
NOTE: This is the maximum usable musical signal forthis source unit. turning the volume beyond this point will increase noise and distortion without an increase in musical signal. If you can increase the source unit volume to maximum without audible disortion, raise the output level controls slightly and begin again.
4.With the amplifier gains still at minimum and the source unit set at maximum volume without distortion, raise the front output level control until distortion is heard, then reduce gain to just below this point. This is the maximum output level for this system. For best performance do not increase beyond this point.
