Installing in a Rack One of Alesis’ goals is to make high-quality music technology available to everyone. How to Use This Manual This manual is divided into the following sections describing the various functions of and applications for the DEQ While it’s a good idea to read through the entire manual once carefully, those having general knowledge about qlesis equipment should use the table of contents to look up specific functions.

Important Safety Instructions Important Safety Instructions English Safety symbols used in this product This symbol alerts the user that there are important operating and maintenance instructions in the literature accompanying this unit.

This symbol warns the user of uninsulated voltage within the unit that can cause dangerous electric shocks.

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. Operation is subject to the following two conditions: Select program 00 on the DEQ 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. 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” Program mode When this manual refers to Program mode, we mean the very top level of functionality of the DEQ In this mode, you have access to the 30 Preset programs and 30 User programs.

Bypass mode This mode is nearly as simple as it sounds: 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. 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 DEQ has 60 programs in all: The Preset programs are the ones numberedwhile the User programs are numbered This can help you determine exactly which band you need to highlight or de- emphasize.

But what about the band that was set to 0 dB originally The answer is, “Yes and no. This is because the DEQ takes into account the gain setting of all of the bands when an Edit Group is formed.

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. 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.

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.

Channel Level mode–you may have entered Band Edit mode by mistake. To begin the pyrotechnics, first make sure you are in Program mode. To access Setup mode, first you must turn off the DEQ When a hot line level signal comes in, the DEQ has plenty of headroom to deal with it. But if you perform some radical 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. Basics of Equalization Button 9: System Exclusive Alesia Waiting As long as this page is active, the DEQD will allow an external device such as a computer to transmit a new bank of 30 User programs into its User memory space.

Button combinations Here is a list of the combinations of buttons that are possible in the DEQ and what they do: If you boost too many frequencies too high, you will distort the output. To avoid this, turn down the signal being sent to the Aleiss Other options include adjusting the Channel Level settings in Edit mode, or adjusting feq230 Master Level setting in Setup mode. What makes the DEQ unique? Req230 their inception, graphic aledis relied solely on a form xeq230 equalization known as “Variable Q.

This method of equalization is a relatively recent development in the history of sound reinforcement and recording technology. 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. 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.

Q equalizers out of hand; in some applications either would do the job nicely. But aleiss a greater degree of control over the program material is needed, a constant Q equalizer like the DEQ offers a significant advantage.

Applications This section is designed to get you started with the DEQ by giving some sample settings. 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. Comb filtering You’ll understand how this effect process got its name once you see the way it looks when recreated on the DEQ Darken Speech Description The DEQ will not affect the signal; the output signal deq2330 sound the same as the input signal.

The smile curve is a time-tested technique used by live sound engineers. No time for a sound check? It makes for a nicely balanced sound when listening at low levels. 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. 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 aesis that calls for woof and hot treble, send it through this curve.

This curve gives the signal a little alseis life when you want to get the listener’s attention. Thanks to the digital heart of the DEQ, you can always get the program back exactly as it was. Make sure you really want to erase every program you have stored.

That is what reinitializing the unit does. If you haven’t already done so, turn off the DEQ Reduce gain of problem bands within program. Reduce channel levels of that program. Reduce Master Level in Setup mode. Unlock DEQ in Setup mode.

Refer to page Troubleshooting Refer All Servicing to Alesis We believe that the DEQ is one of the best signal processors that can be made using current technology, and should provide years of trouble-free use.

However, should problems occur, DO NOT attempt to service the unit yourself unless you have training and experience. Switch set to —
