3-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 tweeters will not operate below 5000Hz.
•Most 6” midranges will operate down to
•Most 5” or 4” midranges will operate down to
•Most subwoofers have decreased sound quality when operated above 150Hz.
Depending upon the size/type of the midranges and tweeters and the type of subwoofer system, fine tuning these adjustments may be required after the initial system
2.The
NOTE: An exception will be when the midrange is too small to play down to a very low frequency and the subwoofersounds distorted trying to “play up” to meet the midrange. This may require a gap or difference 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 and Rear Output Levels
Before setting front and rear level controls, disconnect the subwoofer output and follow the directions below.
1. Be sure the front and rear
NOTE: When the MCD360 is used in a
2.Turn the front and rear output level controls to their minimum setting.
3.Turn the amplifier gain controls to their minimum setting.
4.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.
5.With the amplifier gains still at minimum and the source unit set at maximum volume without distortion, raise the front and rear output level controls until distortion is heard, then reduce the gain to just below this point. This is the maximum output level for this system. For best performance do not increase beyond this point.
