Can I connect an external HDD to ‘USB Audio In’ on the CXA61/81?

No, there is no way to connect a USB drive or HDD directly to the CXA61/81 using its ‘USB Audio’ input. The ‘USB Audio’ input on the CXA61/81 will only support a direct connection with a PC or Mac. You will, however, be able to use one of our network players in combination with the CXA61/81 to do this.
