1 Quick Start Guide

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 DEQ230. The fastest way to do this is to press the [DOWN] and [UP] buttons at the same time. This will call up a program with all frequencies set to 0 dB, which will allow 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 green LED over the word SIGNAL begins to light up on each side. Carefully increase the mixer’s output level until the green LEDs are lit most of the time. If the red LEDs light up at all, back the mixer’s output level down until they stop lighting up. This is important, because the 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 [DOWN] and [UP] buttons on either side of the [POWER] switch 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.

Step 3: Store the Program

Once you have created an interesting program, you can save it to one of the 30 User program locations. Here’s how to do this:

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

2.Use the [DOWN/UP] buttons to select the new location for the edited program. For your convenience, programs 55-59 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 [STORE] button again to store the program to the new location.

For a detailed explanation on how to use this mode, see page 38.

Remember: if one or both of the red LEDs light up, that means the signal is clipping. To prevent this, reduce the level being sent to the proper channel.

Programs 55-59 have been left “blank” so you have places to store your new programs right away.
