Source connections

Important: Do not turn on any of the units until all connections have 

been made.

When designing our products we include features that allow you to 

connect your system in various ways. The inclusion of these features 

means that you can flexibly  configure your system depending on your 

requirements. 

Unbalanced audio connection

The diagram below shows a Stream Magic 6 being connected to Digital 

Input 1 of the 851D, which is in turn connected to the 851A via the 

Unbalanced ouput.

PC–USB connection

The  diagram  below  shows  the  USB  audio  input  connection  from  a 

personal computer using a type A-B USB lead to your 851D and an 851A

Note:

  Always  use  a  certified  cable  for  USB  Audio,  preferably  one  that 

displays  an  official  USB  Audio  2.0  logo.  The  cable  should  be  the  ‘Hi-

Speed USB’ certified. USB cable connections longer than 3m may result 

in inconsistent audio performance.

Bluetooth audio connection

The diagram below shows the bluetooth audio input connection of your 

paired device to your 851D using the BT100 bluetooth dongle and a 

851A amplifier using Source 1 (Balanced).
