The answer is 3 18 x 10 6 F or an approximate 3 3puF Try larger and smaller values to create different response curves For low frequency drivers you can try a different enclosure types or placement Equalizer Solutions In this situation boosting the DEQ 30 is really the only solution Care must be taken not to exceed the excursion limits of the woofers and the power handling of the tweeter Also do not exceed the maximum undistorted output level of the DEQ 30 When you exceed the maximum output level it is indicated by the illumination of the Clip LED located on the front display panel 39 ROLL OFF RESPONSE PROBLEMS 25H2 3 5Hz 4UHz 50H2 63Hz 80Hz 00Hz 25Hz 60Hz 200Hz 250Hz 3 5Hz 400Hz 500 Hz 630Hz 800Hz 100UHz 1250Hz 1600Hz 2000Hz 2500Hz 3150Hz 4000 Hz 5000Hz 6300Hz 8000 Hz 0000 Hz 25UU Hz 6000Hz 20000Hz 38 The DEQ 30 can accept a direct digital signal from a Compact Disc Mini Disc or DAT source unit 44 1 kHz and 48 kHz sampling frequencies Both TOSLINK and COAX connectors interface with a professional grade SPDIF receiver That allows direct access to the digital processor inside SELECTING DIGITAL INPUTS The Analog Digital push button selector switch determines whether analog or digital inputs are used When the push button switch is in the out position the DEQ 30 is configured for analog input RCA or Balanced When the push button switch is in the in position th2. Absorption Reflection Related Non Linearity Problems are caused by the interaction of speakers with the interior acoustics of the vehicle Examining the speaker mountings and locations may give clues to potential problems and potential solutions Be sure the speakers have an un obstructed path to the listening position Any object in the speakers path will affect the sound quality of the system Non Equalizer Solutions Examine the surrounding of the speaker If any object blocks the path of the speakers remove it If this is not possible minimize the effect of the obstruction by applying a type of absorption material on the object like felt or high density fiberglass Install the absorption material in the path between the speaker and the obstruction so as to minimize the effect If the rear of the speaker midrange or woofer is close to a reflective panel place damping material between the speaker and the reflective baffle Also if any frequency response errors occur near crossover points try changing the speaker polarity of the speaker or try using different crossover frequencies Equalizer Solutions Use the DEQ 30 first as a cut only device to try to smooth out the non linearity of the system Cut frequencies gradually starting with the center point of the problem area Do not cut the centered band to get the frequency response to the flat position for it will dip below when you change adjacent bands When boosting the DEQ 30 is required take

28. raph the midrange output level is lower than what is needed to match the woofers and tweeters This is usually an easy problem to solve without the use of an equalizer Non Equalizer Solutions First try balancing the output between the midrange and tweeter For this example reduce the level of the tweeter If you have passive crossovers between the midrange and the tweeters attenuate the level of the tweeter If you have an active system balance the level between the midrange and the tweeter by raising the level of the midrange Once you have achieved a balance between the tweeter and midrange integrate the level of the woofer by similar tuning techniques Equalizer Solutions If you have followed the instructions above there should be little need for equalization However if equalization is still required use the DEQ 30 as a cut only device to try to smooth out the non linearity of the system Cut frequencies gradually starting with the center point of the problem area Do not cut the centered band to get the frequency response to the flat position for it will dip below when you change adjacent bands Periodically listen to your system during this process to make sure the changes you make do not adversely affect the detail and sound quality of the system 33 OUTPUT LEVEL INCOMPATIBILITY PROBLEMS N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N T t Z TL ft Z T Fr LITI ZE YE TE Z re I x xE II x Ln N

33. uctive interference as a result of integrating two drivers with crossovers The above situation is a three way system with crossover points of 100 Hz and 2 500 Hz In both situations the driver interaction has caused a destructive interference at the crossover frequency Non Equalizer Solutions The first thing to try is to change the polarity of one of the drivers A general rule of thumb change the polarity of the driver that has a lower operating band In the above situation first try inverting the polarity of the midrange to see if there is an improvement If this does not improve the situation return the polarity to its original setting and try using different crossover points for both the midrange and tweeter Remember to use crossover frequencies that are at least as high as the recommended operating range When dealing with multiple response errors start with the highest frequency problem area and work downward Equalizer Solutions Use the DEQ 30 as a cut only device to try to smooth out the non linearity of the system Cut frequencies gradually starting with the center point of the problem area Do not cut the centered band to get the frequency response to the flat position for it will dip below when you change adjacent bands Periodically listen to your system during this process to make sure the changes you make do not adversely affect the detail and sound quality of the system 35 CROSSOVER POINTS amp SPEAKER POLARITY PHASE SHIF
