Alesis DEQ230D User Manual

 

 

The insert sends on a guitar or bass amp are usually labeled 

"effects send and return" or "insert send and return." This allows 

your instrument to be boosted to line level before the signal is sent 

to the equalizer, processed, and returned to the power amp. 

 

 

 

 

 

 

  

Another method would be to insert the DEQ230 between the 

preamp and the power amp, if  you are using a two-piece system. 

You should never put the equalizer between the power amp and 

the speaker, as the high-powered levels created by the power amp 

will damage the unit. 

 

 

 

If  you are connecting the DEQ230 to a product with XLR 

balanced inputs and outputs, you will need to convert this signal to 

a TRS balanced connector. Make sure that pin 2 of  the XLR 

connector is connected to the tip of  the TRS adapter, and pin 3 is 

connected to the sleeve.  

 

 

Connecting to equipment with S/PDIF 
inputs and outputs (DEQ230D only) 

 

The DEQ230D has the added capability of  receiving and 

transmitting its audio signal in the digital domain. This is done 

through a pair of  coaxial connectors (also known as RCA jacks) 

found on the rear panel. The jacks are labeled S/PDIF In/Out: 

each carries two channels of  audio, so both Channel A and 

Channel B are handled by a single cable in each direction. 

 

Using the S/PDIF jacks to connect to an external device such as 

the Alesis MasterLink is very easy, because the DEQ230D will 

automatically switch over to the S/PDIF input when it senses that 

a valid digital signal is present.
