User manual CLARION MCD360

[. . . ] Output Level Controls - Seperate Front, Rear and Subwoofer Output Level Controls allow you to set the nominal operating level of the crossover. The crossover's output level ranges can accommodate virtually any brand of amplifier. It acts much like an equalizer, with adjustable gain (from 0 - +18dB) with a center frequency adjustable from 25Hz - 100Hz. Use this feature to tune low-frequency audio response to compensate for a less than ideal subwoofer enclosure design. [. . . ] After determining which system best fits your requirements, thoroughly read and follow the directions below for your system type. Figure 4 - In this illustration, the MCD360 is configured for two channel input with dedicated amplifiers for front speakers, rear speakers and subwoofer(s). 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. The following are some guidelines if this information is not available: · 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 set-up. Study the system design pages of this manual to determine the proper settings for these controls. Speakers are easily damaged if they are crossed over at a frequency below their usable range. When making the high frequency adjustments, adjust the Low-Pass frequency control and the low frequency amplifier gain. Usually, the LowPass frequency should be set the same as the High-Pass frequency. 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. Turn the source unit on and increase the volume until distortion is heard, then reduce volume to just below this point. 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. 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. Setting the Rear Output Level Before setting rear level controls, disconnect both the front output and the subwoofer output and follow the directions below. Turn the source unit on and increase the volume until distortion is heard, then reduce volume to just below this point. [. . . ] Setting the Front and Rear Output Levels Before setting front and rear level controls, disconnect the subwoofer output and follow the directions below. NOTE: When the MCD360 is used in a 3-way system, the front outputs must be connected to the tweeteramplifierand the rearoutputs must be connected to the midrange amplifier. Turn the front and rear output level controls to their minimum setting. Turn the source unit on and increase the volume until distortion is heard, then reduce volume to just below this point. [. . . ]
