37Installation and wiringCarefully unpack the amplifier and store the originalpacking material carefully. The carton and packing arespecially designed for this unit and will be needed again ifyou wish to move the equipment at any time.Please read the safety notes in these instructions.If the unit gets very cold (e. g. when being transported),condensation may form inside it. Please do not switch iton until it has had plenty of time to warm up to roomtemperature, so that any condensation evaporatescompletely.Before placing the unit on a sensitive surface pleasecheck the compatibility of the laquer and the unit's feet ona non visible point.The unit should be placed on a rigid, level base. Whenplacing the unit on resonance absorbers or anti-resonantcomponents make sure that the stability of the unit is notreduced.The amplifier should be set up in a well ventilated dry site,out of direct sunlight and away from radiators.The unit must not be located close to heat-producingobjects or devices, or anything which is heat-sensitive orhighly flammable.When installing the amplifier on a shelf or in a cupboard itis essential to provide an adequate flow of cooling air, toensure that the heat produced by the unit is dissipatedeffectively. Any heat build-up will shorten the life of theamplifier and could be a source of danger. Be sure toleave at least 10 cm free space above the amplifier forventilation. If the system components are to be stackedthen the amplifier must be the top unit. Do not place anyobject on the top cover.Mains and loudspeaker cables, and also remote controlleads must be kept as far away as possible from signalleads and antenna cables. Never run them over or underthe amplifier.The wiring diagram shows a typical wiring arrangement forthe amplifier integrated amplifier within a 'R' system.Notes on connections:• Be sure to push all plugs firmly into their sockets.Loose connections can cause hum and other un-wanted noises.• When you connect the input sockets of the amplifier tothe output sockets on the source devices alwaysconnect like to like, i. e. 'R' to 'R' and 'L' to 'L'. If youfail to heed this then the stereo channels will be rever-sed.• When connecting a recorder be sure to connect the INsockets of the recorder to the OUT sockets of theamplifier, and the OUT sockets of the recorder to theIN sockets of the amplifier.• If the remote control module is installed connect theplug on the E 2000 remote control receiver to thesocket marked RC-IN E 2000. The RLINK socket ofthe amplifier should be connected to the RLINK socketof the source devices (see 'Wiring diagrams').• The amplifier integrated amplifier is designed to beused with an 230 V AC (alternating current) mainssupply. Connect it to a correctly earthed mains socketusing the mains lead supplied.• The amplifier can also be used in Bi-Wiring orBi-Amping mode. These wiring variants are shown in aseparate wiring diagram.• To achieve maximum possible interference rejectionthe mains plug should be connected to the mainssocket in such a way that phase is connected to themains socket contact marked with a dot (). Thephase of the mains socket can be determined usinga special meter. If you are not sure about this, pleaseask your specialist dealer.We recommend the use of the  'POWER LINE'ready-to-use mains cable and the 'POWER BAR' mainsdistribution panel which is fitted with a phase indicator asstandard.When you have completed the wiring of the systemplease set the volume control to a very low level beforeswitching the system on.Switch on the loudspeaker outlet to which your speakersare connected and switch the integrated amplifier to thelistening source which you wish to hear. You should nowhear the music.If you encounter problems when setting up and using theamplifier for the first time please remember that thecause is often simple, and equally simple to eliminate.Please refer to the section of these instructions entitled'Trouble shooting'.
