PowerSupply
The amplifierrequiresa14VDCpowersupply.Themaximumcurrent is
3.2A.
The abitana power supplyABI-PS1003S00 hasbeen chosen tomeet
theserequirements.
It ispossibletodaisy-chainthe power supplytoasecond or eventually
third amplifier (maximum3amplifiersinone chain),using the supplied
jumper cables.
Importantremark: The maximumrequired power shouldnotexceed
the power limits ofthe power supply.
Incasemore than3amplifiersareconnected toapower supplywith
sufficientpower capacity,the powersupplyshouldhavemultiple
outputs.
6Installation
REMARK: TheBlackterminalsofthespeakerconnectorsareNOT
connectedtogroundandshouldNOT beconnectedtoanyother
black speakerconnectorterminal.
6.1Powersupplyand speakerconnection
Turn off thepower supply.Do notswitchonthepower supplyuntil all
connectionsare made.
Connect thespeakersthatbelongtothezone thatthisamplifierwill
servicetothe corresponding terminals.Stripthe wire over alengthof
5mm.Press theorange lever ofthe connector usingasmall
screwdriver and insertthe strippedwire inthe connector.Releasethe
screwdriver and makesure thatthewire is firmlyheldbythe contact.
Connect the power supplytothe corresponding terminalontopofthe
device.
6.2Connection oftheRadioandControlModule(RCM)
(ABI-MM1000Sxx)
Thisinstructionisonlyvalidforaninstallation in1roomwithoutmulti-
roommodule.
Connect the RJ45 jackon top ofthe unittothe RCMconnector by
means ofthe supplied patchcord.
When the power supplyisturned on,the RCMwill startand switchto
stand-by.Turn onthe RCMand checkthefunctionality.

(mostofthe non-portablemains-powered devices).
The x4settingischosen when theaudiodeviceisalow-outputlevel

6.5.1Volumecontrolusinganexternalpotentiometer
(ABI-MM1005Sxx)
It ispossibletoconnectapotentiometer tothe amplifier tocontrolthe
volume.
The volumecontrol(potentiometer) isconnected toaconnector inthe
wiring cabinet using theabitana cabling.
ThispotentiometerissuppliedwithaRJ45 to3.5mm patchcord.Use
thiscabletoconnectthepotentiometerconnectiontothe3.5mm
volumecontroljackon top oftheamplifier.
WhenanotherthentheABI-MM1005Sxxpotentiometerisused,itmust

amplifier.
The amplifier will be muted when avoltage between 0Vand 1Vis
applied.
The volumewill be controlledin64(logarithmic)stepsbychanging the

6.5.3Volumecontrol usingapassive Homecontrolsystem.
The outputpower ofthe amplifier can alsobe setbyapassivedimmer
controlwhichisconnected tothe 3.5mmvolumecontroljackon top of
the amplifier.
Inthisconfigurationtheabitana amplifierprovidesafixed currentof
100µAon the ring ofthe 3,5mm connector.Assoon asthiscurrentis
provided tothe dimmercontrolmodule,thisone canvarythe control
voltage according totheuser’scommands(usuallybetween 1and
10V).Thetipofthe 3,5mm plug hastobe connected tothe ringto
provide the controlvoltage tothe volumecontrolofthe amplifier.

6.6Lineinput
It ispossibletoconnect the amplifier toanyaudiosourcewithaline
leveloutput. Thissourcecanbe attacheddirectlytothe amplifier when
the sourceislocatednear the amplifier.Incasethe sourceislocated
elsewhere inhouse,itcanbe connected totheamplifier usingthe
abitana cabling and the audioadapters (ABI-MM1009S00).
Connect the audiosourcetothe line inputconnector ofthe amplifier

Turn on the power supplyand checkthefunctionality.
6.7Usageofthelineoutput/ Daisychaining two amplifiers
Itispossibletodaisychain2ormore amplifiersfor larger roomswhere
more power isrequired and/or more speakersare required.Thiscan
easilybeachievedbyconnecting the lineoutputofoneamplifiertothe
line inputof asecond amplifier, using the supplied 3.5mm stereo cable.
Remark:Onlythelineinputsand outputsshouldbeconnected
together!Everyamplifiershouldbedirectlyconnectedtoits
