right channel and “L” for the left channel. It also have single ended line out using RCA sockets, the 
red one marked “R” is for the right channel, the white one marked “L” is for the left channel. 
 

Digital In:

 The dac2541 have a total of 5 digital inputs. 

 

“TOS”:

 SPDIF Optical Toslink. 

“RCA”:

 SPDIF 75 ohms Coax, transformer isolated. 

“BNC”:

 SPDIF 75 ohms Coax, transformer isolated. 

“AES”:

 SPDIF 110 ohms balanced AES/EBU, transformer isolated. 

 

“USB”: 

USB type B socket: For connection to the USB interface on your computer or other audio 

source device. You need to use a high quality USB cable, like the USB cable included with the 
dac2541.The USB interface supports only USB Audio Mode 2, which require drivers for Windows 
operating systems other than Windows 10. 
 

Windows Drivers:

 Drivers for using USB Audio Mode 2 on Windows operating systems are 

available for downloading on 

http://www.soekris.dk/download.html

. Please note that most newer 

versions of Windows 10, Apple OS X and Linux don’t require drivers but will support USB Audio 
Mode 2 directly, see manual for your operating systems as needed. 
 

Power Socket:

 The dac2541 support power input voltage from 90V to 264V AC using a IEC8 

socket, which should enable it to work worldwide directly. The power Supply is double isolated. 
 

Power Cable:

 The dac2541 is supplied with a power cable for the US and EU markets, but any 

power cable designed to fit between an IEC8 socket and the wall power socket in your country can 
be used, it don’t need to be anything fancy.
