Bryston 3BST to BAT VK3i hook up

I have a 3BST amp with XLR connections that will be connected to a VK3i with the same balanced connections. My question: The 3BST labels the top connection channel one, the VK3i labels it L for Left. The 3BST does channel two for the bottom, VK3i R for Right. What is the proper way to connect the XLR's? Thanks.
