USB input and selector switch

Connect a computer to one of these two Type-B USB sockets using a standard USB lead. Set the switch according to the socket used. Most installations should use the left-hand socket for ease of setup. For more information on selecting the best connection, see page E-7

12V trigger input

This socket allows the D33 to be switched in and out of stand-by mode by an amplifier (or another item of AV equipment) with a 12V Trig out function. See page E-5.

AES/EBU digital input

Use this socket to connect equipment with a digital output corresponding to the professional AES3 digital audio standard. See page E-7.

Balanced audio output

Use these sockets to connect to your amplifier if the amplifier has balanced XLR inputs. If your amplifier has unbalanced inputs, use the phono outputs. For further details, see page E-5.

Analogue audio output

Connect these phono sockets to your amplifier’s Aux, CD or other line-level input using suitable high quality interconnect cables. Ensure that the left and right audio outputs from the DAC are connected to the same left and right inputs on your amplifier. See page E-5 for further details.
