Alesis DEQ230D User Manual

Connections 

There are three ways to connect the DEQ230D with another 

digital audio device: 

 

 

A potential use for this setup would be if  you are running your 

recorded tracks into a mixer that only has an analog output, but 

your mixdown deck has S/PDIF inputs. Use the DEQ230D to put 

that finishing touch on the mix, and then use it as a digital audio 

interface into the mixdown deck. In doing this you ensure the 

cleanest possible connection between the DEQ230D and the 

mixdown deck. 

 

To use the DEQ230D in this way, connect the S/PDIF Output of  

the DEQ230D to the S/PDIF Input of  the receiving device. 

 

 

This would be the method to use, for example, if  you have a mixer 

with a digital output for its main mix and an amplification system 

that only has analog inputs. With this setup you would be able to 

pass the audio to the DEQ230D in the digital domain, shape the 

signal using its 28-bit internal processing, and then send the result 

to the amplification system. 

 

Of  course, you could substitute a CD player or DAT deck for the 

mixer in the above example, and/or substitute a mixdown deck or 

a couple of  channels on a mixer for the amplification system. 

 

In this case, connect the S/PDIF Output of  the transmitting 

device to the S/PDIF Input of  the DEQ230D. 

 

 

In cases where every device in your audio chain has a digital audio 

input and output, the DEQ230D is right at home. Simply pass the 

audio from the transmitting device’s S/PDIF Output into the 

DEQ230D’s S/PDIF Input, use it to sculpt the signal, and then 

pass the audio on to the next device by connecting the 

DEQ230D’s S/PDIF Output to the S/PDIF Input of  the 

receiving device. 

 

Operating the DEQ230D in any of  the three configurations 

described above is really no different from using it in a completely 

analog system. For that reason, from this point on in the manual 

we will make no distinction between operating the DEQ230D in 

the digital or analog domains.
