In other cases it is done to change the characteristic sound of a particular signal source such as a voice or a musical instrument. TDM 15GE-2 equalizers can be used for either purpose. -
Page 6: Equalizer Terminology
Cutting a range of frequencies lowers their level relative to the overall signal level. The amount of boost or cut is given in Decibels (dB). TDM 15GE-2 graphic equalizers can provide up to 12 dB of boost or cut for each frequency band. -
Page 7: Mounting The Unit In A Rack
Remove any rack screws from the part of the rack where you are planning to mount the equalizer. Position the TDM 15GE-2 equalizer in the rack as desired. Make sure the mounting holes in the equalizer line up with the screw holes in the rack rails. -

• Power: A power outlet should be located close enough to the unit so that you can plug it in. The 15GE-2 equalizers require a grounded (3-prong) outlet. If an outlet is not close enough, an extension cord or power strip may be used. Check the power rating on the extension cord or power strip to make sure that it exceeds the power requirements of all units plugged into it combined. - Page 9 chorus or flanging units depending on the effect you are trying to achieve. They are typically inserted before delay and reverb units, though they are sometimes used to equalize just the return of a reverb or delay unit to achieve certain special effects. ©...

Page 10: Operating The Equalizer
Operating the Equalizer nce you have mounted your TDM 15GE-2 equalizer in a rack and connected all of the cables, the unit is ready for operation. At this time, make sure the input levels of the amplifiers are all the way down. Next, turn all equipment on. It is always best to turn the equipment on in the order of the signal path from input to output and to turn it off in exactly the reverse order. -

filter has a different range of available frequencies. The high and low points of the range are marked at the top and bottom of the frequency sliders. • Notch Filter Cut Sliders: Each notch filter’s cut slider determines the amount of cut from 0 dB (all the way up) to 40 dB (all the way down). - Page 12 With PA equalization, avoid boosting altogether if possible. It is sometimes advisable to boost the extreme lows (50 and 63 Hz) or the extreme highs (12.5 kHz and 16 kHz) to deal with a PA system that lacks extension on the ends of the spectrum, but if you do this, use only a slight boost.

It is easy to check if the distortion is from your TDM 15GE-2 equalizer: Simply bypass the unit by pressing the bypass switch. If the distortion goes away with the unit bypassed then the distortion is probably coming from the equalizer. -
Page 14: Excessive Noise
If you suspect that the TDM 15GE-2 equalizer is the cause of your noise problem, make sure the unit is plugged into the correct power source. Read the rear panel of the unit to determine the correct voltage and frequency (US models are set up for 110 VAC at 60 Hz). -

DI boxes are often the first option tried when a hum or buzz surfaces. If you suspect that there is a problem with your TDM 15GE-2 equalizer that is causing a hum or buzz, try removing the unit from the system and plugging its outputs directly into power amplifiers with speakers attached. -
