Note: Before connecting your PC to the 851N, ensure you install the required Cambridge Audio Windows 2.0 USB driver on your PC. Please find a link to the most recent USB audio driver here.
After installing the correct driver, using a USB audio cable (Type A to Type B), connect the USB Audio In on your 851N to a USB port on the PC.
If using the front panel controls of your 851N, navigate to Home > Inputs > USB Audio.
If using the StreamMagic app, go to the Home tab, then select USB Audio within the Sources section.
If using the front panel controls of your 851N, navigate to Home > Settings > Audio > USB Audio Class > Then toggle between USB Audio Class 1.0 or 2.0.
If using the StreamMagic app, go to the Home tab, locate the 851N Settings > USB Audio Class > Then toggle between USB Audio Class 1.0 or 2.0.
This will show any connected Cambridge Audio USB Audio device and current sample rate.
Select the 851N as your output device from the drop-down menu. This will appear as 'CA USB Audio'.
Once selected, select Apply, then OK.
