7DAC-V1 Installation and Connection3 DAC-V1 Installation and ConnectionYour DAC-V1 should be installed on a desk or equipment stand intended for the purpose.Ensure it is well ventilated, and do not stand it directly on top of another item of electronicequipment. It should be installed in its final location before connecting cables or switchingon. The DAC-V1 has no standby mode and is intended to be left switched on.Connecting the DAC-V1 to mains power and to a variety of audio peripherals and sourcesis described in the following paragraphs. Diagram 3.1 illustrates the DAC-V1 rear panelconnection sockets.3.1 DAC-V1 Rear Panel Connectionsmains inputand fusepowerswitchanalogueoutput (RCA)analogueoutput (DIN)input 1(BNC)USBinputinputs 2 & 4(coaxial)inputs 3 & 5(optical) signalgroundswitch3.2 Mains Power ConnectionCheck that the mains supply specified on the DAC-V1rear panel is appropriate for your territory. Connect theDAC-V1 to the mains using the supplied cable (or aNaim PowerLine) but do not switch it on until all otherconnections have been made and, if appropriate, theDAC-V1 Windows OS driver application has been installedon the USB connected computer (see Section 2).3.3 Audio Inputs and Outputs3.3.1 Audio Signal InputsThe DAC-V1 provides one asynchronous USB digital inputand five S/PDIF digital stereo inputs. Connection to theinputs is made via a variety of socket types:Input Type SocketUSB Asynchronous USB USB Type Bdig. 1 S/PDIF Digital Coaxial (BNC)dig. 2 S/PDIF Digital Coaxial (RCA phono)dig. 3 S/PDIF Digital Optical (TosLink)dig. 4 S/PDIF Digital Coaxial (RCA phono)dig. 5 S/PDIF Digital Optical (TosLink)Always use high quality interconnect cables to connectsources to DAC-V1 inputs.For optimum audio performance the USB connection fromthe computer to the DAC-V1 should be direct rather thanvia any “hub” device. The USB cable used should be nolonger than 3m.3.3.2 Audio Signal OutputsThe DAC-V1 provides both DIN and RCA phono analogueoutputs for connection to a “downstream” amplifier. Ifthe option is available on the pre or power amplifier, DINsocket connections should be used in preference to RCAphono sockets. The DIN and RCA phono socket optionsshould not be connected or used simultaneously.Always use high quality interconnect cables to connect toDAC-V1 outputs.3.3.3 Headphone OutputThe DAC-V1 incorporates a front panel 6.3mm stereoheadphone socket. Inserting a headphone plug will mutethe DAC-V1 signal outputs. Removing the headphone plugwill restore the signal outputs.
