Overview
For adding or removing connections your SAM must beswitchedoff or
at least thevolumehas to beturned down completely.
Your SAM is equippedwith 6high-levelRCA inputs marked1..6. The
inputs 2..5 areof thesamekind, howeverinput 6is reservedfor re-
cording systems, suchastapedecks or DAT recorders (see below). In the
caseyou purchasedtheoptionalphono modulepleaseuseinput 1for
connecting your turntable.Otherwiseinput 1canbeusedasaregular
input.
Pleaseconnectyour audio sourcesto theinputs of your AudionetSAM.
Do not careabout theorderbecauseit is possibleto assign dedicated
names to theinputs later on.
Thelineout of atape-, video- or DAT-recorderhasto beconnectedto
input 6. For this unit theSAM delivers anoutput signalatthesockets
REC-OUT. Connect this output to thelinein of your recorder.
If therecorderis connectedto input 6therecorder will beprevented from
recording itself. For input 6 theREC-OUT is disabled (muted).
If you connectedtherecorderto input 3, for instance,therecorderwould
getits own output signalroutedbackon theinput. If therecorderis set
into record modethis could causedangerous feedback oscillations!
In caseyou purchasedtheoptionalphono modulepleaseuseinput 1for
connecting your turntableasmentionedabove.Additionally theturntable
chassis hasto beconnectedto theSAM'searth screwlabeled”GND”to
prevent hum.
Thephono modulefits perfectly to all MM- and MC-systemsavailable.
It offers independent settings of theparameters gain, input resistance and
input impedance.For detaileddescription pleasereferto themanual

red) and thewhiteoutputs (-) areconnectedto thenegativeloudspeaker
inputs (usually whiteor black).
Wrong polarization will result in severeloss of sound quality!
Thenominal loudspeaker impedance must be4 ohms or higher!
Although theSAM hasaprotections circuit to prevent damageof the
systemalways switchoff theunit whileworking on theloudspeakerca-
bles. Pleasemakesurethatall cablesarein absolutebest condition. Bro-
kenshields or short-cut loudspeakercablescould damageloudspeakers
