Alesis DEQ230D User Manual

Connections 

This example shows how to connect the DEQ230 to one mono 

source. You can use this method to connect two mono sources or 

one stereo source to the DEQ230. You would need two insert 

cables to make both of  these connections. 

 

Use two insert cables to connect the DEQ230 to the main L/R 

bus in the same way you would connect it to a pair of  channel 

inserts. Simply connect one insert cable to the left main insert of  

the mixer, and connect the two mono jacks to the CHAN A 

INPUT and OUTPUT of  the DEQ230. Use another insert cable 

to connect the right main insert to the CHAN B INPUT and 

OUTPUT of  the DEQ230.  

 

You can also simply connect the balanced main outputs of  the 

mixer to the inputs of  the DEQ230, then connect the outputs of  

the equalizer to the inputs of  your mixdown recorder, monitor 

system, etc.  

 

 

 

Some recording consoles have separate balanced jacks for the 

sends and returns instead of  a single TRS jack. If  your recording 

console has these connections, use a balanced TRS cable to 

connect the insert send to the INPUT of  the equalizer, and 

another balanced TRS cable to connect the equalizer OUTPUT to 

the insert return.  

 

 

The DEQ230D can operate in either a +4dBu or –10dBV setting. 

A rear panel switch allows you to configure the unit to your audio 

environment. 

 

The DEQ230 is a “line level” device, which means that it operates 

at a nominal level of  –10dBV, with a maximum input level of  

+8dBV. Some equipment operates at a nominal level of  +4dBu, 

and can run the signal up to +24dBu. To prevent clipping, reduce 

the level being sent from this equipment.  

 

If  you are unsure about the nominal operating level of  the 

equipment to which you will be connecting the DEQ230, refer to 

the Reference Manual for that equipment.
