- Page 2 This is especially useful in sound-off competition where the DEQ 30 presets can be set for “Sound Quality,” “RTA,” “SPL” and regular listening. The addition of a DEQ 30 to a system is a must for a competition system and for people who demand the best.

RESOLVED IN ACCORDANCE WITH CALIFORNIA LAWS IN SAN DIEGO COUNTY, CALIFORNIA. TECHNICAL OVERVIEW Designed for the person who competes, the DEQ 30 is a must for all high-end systems. Either channel of the DEQ 30 can be adjusted individually or linked together. The DEQ 30 can accept direct digital inputs (TOSLINK or COAX), conventional RCA inputs or Mini-XLR™... -

4 working zones create different preset response curves for every listening preference. ANALOG INPUT SECTION: THE DEQ 30 uses an 18 bit balanced delta sigma analog-to-digital converter with 128 times oversampling. It accepts both RCA and Balanced (Mini XLR™) inputs. Left and right input sensitivity adjustments are fully variable and independent. -

The result is a perfectly timed digital signal. POWER SUPPLY: The power supply used in the DEQ 30 is a balanced high-frequency power supply. For optimal noise isolation, power and signal grounds are isolated. - Page 7 CALL OUT FEATURES D IG IT A 11 12 13 Distorted output Unit’s input sensitivity set too high.

POWER CONNECTIONS The above corrected response is not a perfectly flat curve. For good sound quality in a vehicle a flat curve may sound great when the vehicle is stopped and the engine is off. However, most people put systems in cars to listen to great music with the engine running while driving. - Page 10 SPECIAL NOTE: There is an internal 1.5 AMP AGC fuse located in the DEQ 30. This fuse is designed to blow only in extreme situations like power surges in the vehicles electrical system. In this type of situation, the internal fuse serves to protect the DEQ 30 from potential damage.

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. - Page 12 Properly setting the level of the DEQ 30 requires a test disc with a tone recorded at all bits high (the highest possible recording level). A clip indicator informs you if the level is too high. If you do not have a test disc you can still adjust the input levels but it is much more difficult to maximize the system.

Leaving the source units volume control alone, slowly increase the left gain of the DEQ 30 until the “CLIP” LED indicator becomes illuminated.

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. -

ROLL-OFF RESPONSE PROBLEMS 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. -

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. - Page 18 You can choose any and all of the analog digital outputs depending on your systems needs. Make sure to make connections while the DEQ 30 is not powered on. Failure to do so may result in damage to your speaker system.

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. - Page 22 ZONE FLAT L / R LEVEL • Pressing the “L/R” button selects the DEQ 30 for either left channel, right channel or both channels to be adjusted. The channel being adjusted will be indicated by the illuminated LED indicators. ZONE...
- Page 23 If the problem occurs between channels. Use the DEQ 30 to equalize the left and right channels separately. First pan to the left channel and smooth out non-linearities by using the DEQ 30 as a cut device first. Then pan to the right channel and repeat.
- Page 24 INTERFACE” section of this manual. In this section we will be equalizing both channels together. For optimum performance the DEQ 30 is designed to smooth out irregularities in your system frequency response. This section will deal with basic equalization without the use of any measurement device like a RTA (Real Time Analyzer).
- Page 25 Equalizer Solutions Second, 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 changes adjacent bands.
- Page 26 Continue this process until all the frequency irregularities have been eliminated. Since the DEQ 30 has four preset working zones, work in three of the zones and maintain another as a reference. Periodically, check the sound quality of the “corrected” response with the reference response. If you find that the corrected response sounds terrible in comparison to the reference response, take a listening break and listen to it again.
- Page 27 30, it is recommended to use a RTA (Real Time Analyzer). Several companies offer excellent units: Audio Control 3050A, Coustic RT33, Linear X PC RTA. In this section we will use the RTAs to evaluate and tune the DEQ 30.
