Connecting Your D/AC-1500

Whenyou makeconnections,be careful to avoid tensionon eitherwires or fiber optic cableswhich might causedamageto the connectorsor causethemto pull looselater on. Do not attemptto bend eithercoaxialor optical digital cablesat a sharpangle,asthis may permanentlydamagethem. It is safestto turn off thepower of your preampand poweramp while making connections,not only for theconnectionsyou are making, but to avoid the chanceof disturbing adjacentconnections. As an additionalsafeguard,turn your preamp'svolume control to minimum beforemaking new connections.

Digital Inputs

The D/AC-1500 hasfour digital inputs:

. Coaxial I: RCA jack - 75a standard

. Coaxial 2: RCA jack - 75a standard

. Optical 1: Fiber Optic -ST module

.Optical 2: FiberOptic-TOSlink

. Coaxial output connections are provided on most high quality CD players. You should use

only good quality cables which have been designed for digital data transmission. Cables designed for audio frequencies are not suitable and will not give you satisfactory results.

. TOSlink fiber optic connectionsarealsopopularandare found on mosthigh quality video
