But even beyond Page 6: Deq Key Features Introduction DEQ Key Features Offers the best of digital technology and analog-style control: a graphic display with instant editing of any band or combination of bands, plus the ability to store programs 60 programs total: 30 preset and 30 user-programmable While it's a good idea to read through the entire manual once carefully, those having general knowledge about audio equipment should use the table of contents to look up specific functions.

This symbol warns the user of uninsulated voltage within the unit that can cause dangerous electric shocks. Page 10 Important Safety Instructions Use only with a cart, stand, bracket, or table designed for use with professional audio or music equipment. In any installation, make sure that injury or damage will not result from cables pulling on the apparatus and its mounting. Page 12 Important Safety Instructions Page 14 Important Safety Instructions Operation is subject to the following two conditions: 1 This device may not cause harmful interference and 2 this device must accept any interference received, including interference that may cause undesired operation.

Select program 00 on the DEQ Page 19 Quick Start Guide Page 20 Quick Start Guide Thermal Considerations in Rack Mounting The DEQ can be mounted in an equipment rack occupying one rack space or placed on a table or shelf.

The DEQ will work with any standard line voltage from to volts as long as the appropriate detachable power supply adapter is used. The DEQ has been shipped with the suitable adapter for the line voltage in your area. To use the DEQ as an effects insert device, you will need an insert cable not included.

This cable splits the TRS insert jack into two unbalanced mono connectors. Make sure that pin 2 of the XLR connector is connected to the tip of the TRS adapter, and pin 3 is connected to the sleeve. These should be low-capacitance shielded cables with a stranded not solid internal conductor and a low-resistance shield. Although quality cables cost more, they do make a difference. Page 28 Connections This page intentionally left blank What is equalization?

An equalizer boosts or cuts a frequency range. The DEQ is a graphic equalizer, which means it has many fixed frequency bands that can be cut or boosted. The term "graphic" is appropriate because the combined settings of the bands often resemble a curve, or a "graph. This means the DEQ is in Bypass mode. This is useful for comparing the "equalized" In this mode, you have access to the 30 Preset programs and 30 User programs.

There are also two gain adjustment stages that can be used to compensate for a reduction or increase in signal level caused by the equalization curve being used. Page Basic Operation: Program Mode Program mode is where to be if you want to call up another program, or if you just want to know the number of the program you are using. The Preset programs are the ones numbered , while the User programs are numbered This can help you determine exactly which band you need to highlight or de- emphasize.

Page 37 But what about the band that was set to 0 dB originally The answer is, "Yes and no. Page 38 This is because the DEQ takes into account the gain setting of all of the bands when an Edit Group is formed. Page 39 To decide which option suits your working method or circumstance, experiment with the setting for the Release Edit Group function in Setup Mode. If you continue pressing the [UP] button, the DEQ will jump forward through the User locations in increments of 10 40, 50, 30, 40, 50, etc.

Page Channel Copy Channel Copy You can use the Link function while editing to help set up identical curves on both channels. But at some point the curves may need to diverge slightly or significantly.

Rather than unlinking the channels and starting all over again on Channel B, we have included a handy feature called Channel Copy as a subset of Store mode. Page 43 If you have a lot of programs in the Audition List, hold down one of those buttons and after a couple of seconds the DEQ will begin to scroll through them more quickly.

To begin the pyrotechnics, first make sure you are in Program mode. Page 47 DEQ from clipping. When a hot line level signal comes in, the DEQ has plenty of headroom to deal with it. But if you perform some radical Page 48 Edit Time Out is a feature you will appreciate. On the other hand, if you prefer to have the DEQ remain in Edit mode so you will not lose your chosen Edit Group when the unit returns to Program mode, you may want to turn the Edit Time Out function off.

Your DEQ is now locked. No fair using this knowledge to play tricks on your salesperson! It's simple to restore the DEQ to full functionality i. Button combinations Here is a list of the combinations of buttons that are possible in the DEQ and what they do: Hold: Press: [UP] First press Page Equalization Artifacts If you boost too many frequencies too high, you will distort the output. To avoid this, turn down the signal being sent to the DEQ Other options include adjusting the Channel Level settings in Edit mode, or adjusting the Master Level setting in Setup mode.

Page Constant Q Vs. At their inception, graphic equalizers relied solely on a form of equalization known as "Variable Q. This method of equalization is a relatively recent development in the history of sound reinforcement and recording technology.

Page 54 Basics of Equalization In the next illustration, the difference between a narrow Q and a wide Q is seen: Variable Q Now we're ready for a visual definition of the term Variable Q. In the next illustration, the wider and more gradual curve represents a lower gain setting for a variable Q equalizer. Page 55 Basics of Equalization Multi-band application and results So far we have only dealt with cutting or boosting single frequency bands. The differences between the constant Q and variable Q methods become more "graphic," if you will, when adjacent frequency bands are involved.

In this example, three adjacent bands are used. Page 56 Q equalizers out of hand; in some applications either would do the job nicely. But when a greater degree of control over the program material is needed, a constant Q equalizer like the DEQ offers a significant advantage. These are merely suggested settings; experiment and find your own once you begin to hear what the DEQ does to your sound. Follow the instructions for items 1 and 2 from Step 2. Page 59 Comb filtering You'll understand how this effect process got its name once you see the way it looks when recreated on the DEQ 1.

Page 60 Applications This page intentionally left blank The smile curve is a time-tested technique used by live sound engineers. No time for a sound check? Start here. It makes for a nicely balanced sound when listening at low levels. Page 63 Send the signal you want to equalize through Narrow Boosts to find the frequency that may be most objectionable.

Take note of that frequency for further editing or just set the DEQ to the Narrow Cut program that matches the Boost program that emphasized the frequency range in question. Page 65 Narrow Cut 4 2. They can be overwritten with your own programs. Naturally, if you have done that, the following diagrams no longer apply. We suggest that you try these before storing a new program in their place, though; This is one place to start looking for that special fit. If you've got a drum machine or drum mix that calls for woof and hot treble, send it through this curve.

Page 68 Program Charts 11kHz Sample Rate Next Door Neighbor Note for programs These three following programs are for DJ's to squash the response of the music in order to create a temporary effect or to announce over. Page 69 Proximity Effect Presence Distance Combfilter Combo Blank Blank This curve is meant to mimic the physics phenomenon that the closer your ear or a microphone gets to a sound source, the more the bass is emphasized.

This curve gives the signal a little more life when you want to get the listener's attention. Page 70 Thanks to the digital heart of the DEQ, you can always get the program back exactly as it was. Page 72 Program Charts This page intentionally left blank
