USB Connector 
USB (Universal Serial Bus) V1.1 is an external peripheral 
interface standard for data transmission. Xone:S2 USB 
works at 12Mbps and provides two stereo uncom-
pressed audio channels. It is fully compatible with USB2. 
The USB connection is used to send and receive audio 
data between the Xone:S2 and a connected computer. 
Use a standard type A to B lead to connect to your 
computer. 
In the default configuration, the USB input to PC is from 
the RCA Phono connectors on the rear of the mixer.  
Internal option links can be set to change this to the 
pre-fade mix output.

Headphone Outputs 
Stereo 1/4” TRS jack and 3.5mm mini-jack. Plug in good 
quality stereo headphones intended for DJ monitoring. 
Use closed-ear headphones that provide maximum 
acoustic isolation when cueing your sources. We rec-
ommend that you use high quality headphones rated be-
tween 30 to 100 ohms impedance. 8 ohm headphones 
are not recommended.
