Alesis DEQ230D User Manual

Here's a description of  what each function does.  

 

The Master Level function is one way to customize the DEQ230 

to your environment. If  the equipment in your setup tends to send 

very hot signals, you can use this function to prevent the output of  

the DEQ230 from clipping.  

 

When a hot line level signal comes in, the DEQ230 has plenty of  

headroom to deal with it. But if  you perform some radical 

equalization on this signal, it is possible that the combination of  

the incoming hot signal plus the equalization you have done may 

put the signal "over the top" and within range of  clipping. The 

Master Level function allows you to reduce the level of  the 

equalized signal before it reaches the final output stage of  the 

DEQ230.  

 

Don't confuse this with the Channel Level settings in Edit mode. 

The Channel Level settings are stored with the program, and 

therefore may vary from program to program. The Master Level 

setting is global; i.e., it is always active and will affect every 

program. There is a diagram on page 30 that illustrates the 

relationship between Channel Level and Master Level. 

 

To lower or raise the Master Level setting, use the [DOWN/UP] 

buttons. To reset the value of  this function to 0 dB, press the 

[DOWN] and [UP] buttons at the same time.  

 

For an explanation of  how to use the Channel Level control 

feature, see page 42.  

 

 

Of  all the Setup features, this is the one that will most affect the 

way you work with the DEQ230. The Release Edit Group setting 

determines the behavior of  the [BAND SELECT] buttons in 

Edit mode.  

 

For the sake of  describing this feature, let's review some things we 

already know. When you press a [BAND SELECT] button, you 

enter Edit mode. If  you don't press one of  the [DOWN/UP] 

buttons right away, you can keep pressing [BAND SELECT] 

buttons until you have several of  them selected simultaneously. 

This is called selecting an Edit Group.  

 

Once you have selected an Edit Group, you can cut or boost the 

gain of  all of  the bands in the Edit Group simultaneously; they 

will move up or down in proportion to one another. The Release 

Edit Group feature does not affect these things; this is always how 

the DEQ230 operates.  

 

However, once you make an edit, it makes a big difference whether 

the Release Edit Group feature is on or off. If  it is on, the very 

next [BAND SELECT] button you press will "release" all of  the 

previously selected bands. The only band that will be selected is 

the one you just pressed. You will know this when it happens, 

because that's the only Band Gain LED that will be blinking.
