R CONNECTIONS The loudspeakers should be connected using a suitable pair of cables designed specifically for audio use Check with your dealer for advice The 100A s high grade speaker terminals allow for bare wire 4mm plugs or spade lug connectors Tighten the terminal fully after fitting the loudspeaker wire Please consult your dealer for advice if you are unsure It is very important to connect the loudspeakers with the correct phase Cables are normally polarised with a line or writing on the positive side to assist in this Connect the red or pos itive or terminal of your loudspeaker to the red terminal of the amplifier and likewise for the black If both channels are not connected with the same polarity a severe loss of bass performance and lack of stereo image will result It is very important not to short circuit the loudspeaker cables together when the 100A is powered on as permanent damage may result Ensure there are no strands of cable bridg ing the terminals when connecting the loudspeakers and make all connections with the 100A turned off If it is necessary to change or move the location of the loudspeakers make sure that you first turn off the 100A and then re check the wiring once finished Speakers A and B The 100A is capable of connecting two pairs of speakers and controlling them with the front panel menu or remote handset To select speakers A B A B or no speakers press the menu button on the front pa
