Quick Start Guide 

 

USB Audio Interface 

 

 

The ml:1 can be used as a plug & play USB audio interface for playback applications. As the 
interface  is  a  bus  powered  device,  all  power  needed  in  USB  applications  is  provided 
through  the  USB  connector.  The  maximum  current  draw  of  the  ml:1  is  less  than  40mA 
offering a decent runtime even with battery powered solutions.

or system controller 

USB 

analog outputs (balanced) 

connect laptop to active speakers 

 

 

Note that the audio sent to the device through USB will always be routed 
simultaneously to the analog and the digital XLR connectors. 

 

Initialization of the ml:1 as USB device 

Since  the  ml:1  is  a  USB  audio  class  1  compliant  devices,  the  initialization  of  ml:1  on  the 
computer, laptop or mobile device should be done automatically by the operating system.  

 

Depending on your operating system, the initial initialization of the device will 
take between one (Mac OS, Linux) and 15 seconds (windows).

 

All subsequent initializations should only take a second on all operating 
systems.
