INTRODUCTION The Clarion MCD360 is a full-featured Three-Way Crossover. When used to build a 2-way system with front and rear fader capability or a full three-way system, the Clarion MCD360 electronic crossover allows you to choose from a wide range of crossover points between the front, rear and subwoofer outputs.
INPUT/OUTPUT CONNECTIONS AND AUDIO CONTROLS The top panel of MCD360 contains the controls for the crossover and output levels as shown below. Figure 1- 1. Front RCA Input 2.

• Front High-Pass Crossover Frequency Adjustment - Adjusts the crossover to match your speaker system. The crossover frequency can be adjusted from 32Hz - 400Hz or from 640Hz - 8kHz with the crossover frequency multiplier switch. • Rear High-Pass Crossover Frequency Adjustment - Adjusts the crossover to match speaker your system. The crossover frequency can be adjusted from 32Hz - 400 Hz. • Subwoofer Crossover Frequency Adjustment - Adjusts the crossover to match your speaker system.
MOUNTING PRECAUTIONS The MCD360 crossover can be mounted in any convenient location in your vehicle that allows access to the controls and is away from moisture. The flanges on the chassis have mounting holes which can be used as a template for screw holes. For easy system set-up, mount the crossover so the front panel controls will be accessible after installation. In addition, observe the following precautions: 1. Mount the crossover on a rigid surface.
WIRING PRECAUTIONS Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer. If you are using a source unit, without a remote turn-on lead, the MCD360 can be turned on with a switched accessory lead. You can find this accessory power source in the factory harness at the back of the radio. It is the lead that turns on and off with the key. 1. Before installation, make sure the source unit Power switch is in the OFF position. 2.

APPLICATIONS The MCD360 allows you to design either a 2-way system with front and rear output or a full 3-way system. After determining which system best fits your requirements, thoroughly read and follow the directions below for your system type. 2-Way System with Front and Rear Output Figure 4 - In this illustration, the MCD360 is configured for two channel input with dedicated amplifiers for front speakers, rear speakers and subwoofer(s). See Figure 5 for switch settings.
For 2 channel input, configure switches as shown. For 4 channel input with front and rear fade, configure switches as shown. For front and rear fade with dedicated subwoofer input, configure switches as shown.
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 High-Pass and Low-Pass Frequency Controls are set correctly before turning on the system for the first time. Setting the Crossover Frequency Controls 1. Set the crossover frequency controls to the frequency recommended by the speaker manufacturer.
Setting the Rear Output Level Before setting rear level controls, disconnect both the front 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.
3-Way System Figure 6 - In this illustration, the MCD360 is configured for single channel input with dedicated amplifiers for tweeters, midranges and subwoofer(s).
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 High-Pass and Low-Pass Frequency Controls are set correctly before turning on the system for the first time. Setting the Crossover Frequency Controls 1. Set the crossover frequency controls to the frequency recommended by the speaker manufacturer.
Setting the Sub Output Level 1. Make sure all ouputs are connected and both the front and rear output levels are set correctly. Unplug the Remote Sub Level control cable. 2. Be sure the sub output level and amplifier gains are at their minimum settings. 3. With the volume set at a medium level, slowly increase the sub level control to the point where the subwoofer volume blends with the system. 4.
Problem: Midrange speakers “pop” with loud passages. Solution: High-Pass Frequency Control is set too low. Gain Controls on amplifiers are set incorrectly. Reduce the gain setting on high frequency amplifier. Problem: One channel does not operate. Solution: Swap left and right connections at the source unit. If the problem trades sides in the vehicle, then the source unit is the defective. If the problem stays on the same side, proceed on. Swap left and right connections at the input to the crossover.
