The Computer Connector

 

 
On the rear panel of the interface box is a connector labeled 

COMPUTER

. It is 

the point at which the audio interface connects to the Echo3G PCI card inside your 
computer.  
 

 

 
An Echo3G connector cable was supplied to you for this purpose. This custom 
made cable is manufactured to certain specifications; if you need to replace it, you 
should only use a replacement cable from Echo. 
 

ADAT / S/PDIF Optical I/O

 

 
Next to the 

COMPUTER

 connector is a pair of connectors labeled 

OPTICAL,

 

IN

 

and 

OUT

. These connectors are used to transmit digital audio data via an optical 

signal using special digital optical cables with Toslink connectors. 
 

 

 
You can use this port for ADAT (8 channels) or for optical S/PDIF (stereo) I/O.   
 

Note:

 Your Echo3G product is only capable of transmitting or receiving one 

type of digital signal at a time.  You must choose either ADAT optical or 
S/PDIF (optical or RCA); you cannot use both simultaneously. This is set 
using the 

Digital Mode Switch

, which can be found in the Echo Console.  

For more information, refer to the section of this manual that discusses the 
console software.
