Step 2: Try some equalization

Play some signal into the unit

While learning the unit, you should play a CD or a multitrack source into the equalizer. Choose a song or musical passage with a fairly consistent level, so you can take your time experimenting with the different features.

1.Put the mixer’s main faders all the way down so you don’t distort the unit by sending it too much signal.

2.Select program 00 on the DEQ830. This will call up a program with all frequencies set to 0 dB, allowing you to hear the changes you make to the audio more easily.

3.Begin playing your source material. Bring the mixer’s main faders up gradually until the Channel Meters for Channels 1 and 2 begin to light up. Carefully increase the mixer’s output level until the meters’ green and yellow LEDs are lit most of the time. If the red CLIP LEDs at the top of the meters light up at all, back the mixer’s output level down until they stop lighting up. This is important, because these red LEDs indicate that the signal is clipping on that channel.

4.Press one of the [BAND SELECT] buttons to select a frequency. One of the LEDs above that button will begin to blink.

5.Use the [VALUE] encoder to decrease or increase the chosen frequency. If desired, select another frequency and repeat this process.

6.Press the [BYPASS] button to hear the signal without the equalization effect. Press it again to return to the EQ’d signal.

7.Repeat steps 3 – 6 for the other audio sources you have connected to the DEQ830.

Step 3: Store the Program

Once you have created an interesting program, you can save it to one of the 100 user program locations. Here’s how to do this:

1.Press the [STORE] button to enter Store mode.

2.Use the [VALUE] encoder to select the new location for the edited program. For your convenience, programs 25-99 have been left blank so you can store your editing experiments somewhere without fear of overwriting a program you might want to use later.

3.Press the [VALUE] encoder to store the program to the new location. This will preserve the EQ settings for all eight channels of audio.

For a detailed explanation of how to use this mode, see page 41.

At the factory, we set all of Program 00’s frequencies to 0 dB. It’s a good idea to leave Program 00 this way, but if you have already overwritten it with some of your own settings, you can just create your own program with “flat” settings for the purposes of this experiment.

Remember: if the red CLIP LED at the top of a Channel Meter lights up, that means the signal is clipping. To prevent this, reduce the level being sent to the proper channel.

Programs 25-99 have been left blank so you have somewhere to store your programs right away without overwriting the factory presets.
