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

Connecting thespeakers

Connecttheleft and right speakers to theappropriategold platedWBT

terminals attherear. Pleasemakesurethattheredoutputs (+) of the

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
