Phono input english The phono inputs provide a pre-amplification stage to treat the low-voltage output from a moving magnet cartridge. If you have already an external phono amplifier that you wish to use, connect its output to one of the linelevel inputs, such as the AUX input. controlling the a28 from a second room The A28 will require a remote pick-up device with a 12V external power supply (such as a Xantech Dinky Link) located in Zone 2, together with a power amplifier (such as an Arcam A28 or P38) to complete the system. The diagram shows the wiring scheme, which also applies to other IR pick-up devices commonly available. The A28 can also provide a +12V trigger output to control devices such as the power amplifier in Zone 2. The +12V trigger is active when the unit is `On'. Dinky Link, located in Zone 2 Signal +12V 0V REMoTE IN Tip = Signal Sleeve = 0V +12V 0V e-7 Connecting loudspeakers to the A28 loudspeakers Single wiring Single wiring is the conventional wiring method of running a single cable per channel between the amplifier and the speaker; this is the easiest technique. notes on making speaker connections < Do not make any connections to any amplifier while it is switched on. We recommend that your amplifier is completely disconnected from the mains supply before starting. Before switching your amplifier(s) on for the first time after connecting to speakers, please check all connections thoroughly. Ensure that bare wires or cables are not touching each other or the amplifier's chassis (which could cause short circuits), and that you have connected positive (+) to positive and negative (­) to negative. Be sure to check the wiring for both the amplifier and the speaker. After making connections: switch the amplifier(s) on, select a source signal, then gradually increase the volume to the required listening level. If you are unsure as to how your system should be connected, or need advice on bi-wiring or bi-amping, please contact your Arcam dealer who will be happy to help you. bi-wiring Bi-wiring is running two separate cables between the amplifier and each speaker, with one cable carrying the low-frequency information, the other the higherfrequency signals. Bi-wiring can improve the sound of your system because the separation of high- and low-frequency signal currents into different speaker cables avoids distortions caused by the different currents interacting with oneanother within a single cable. The A28 is designed to allow easy bi-wiring, but your loudspeakers need to provide separate terminals for the two cables. Each speaker must have two pairs of terminals; one pair labelled hF or `High Frequency', the other pair labelled LF or `Low Frequency'. < < bi-amping Bi-amping is the separation of the amplification of lowand high-frequency signals over two amplifiers. Bi-amping requires the use of two amplifiers per channel. Normally, your A28 is used to drive the highfrequency (treble) speakers, with a P38 used for the lower (bass) frequencies. < e-8 Single wiring english The A28 is designed for bi-wiring, which is why there are duplicate speaker terminals on the back. For single wiring, we recommend that you use the lower set of speaker terminals on your amplifier. If each speaker has more than one pair of connecting terminals, use the terminals labelled LF or `Low Frequency' for each speaker. Connect the positive terminal of the right speaker connection on the amplifier (coloured red and labelled +R) to the positive terminal of your right speaker. Similarly, connect the negative terminal of the amplifier (coloured black and labelled with R­) to the negative terminal of your speaker. Repeat the process for the left speaker, using the amplifier terminals labelled +L and L­. If your speakers support bi-wiring, then there is a strip of conductive metal on the speakers connecting the low-frequency terminals to those for the higher-frequencies; this mUST NOT be RemOVeD in a singlewired system. An A28 connected to speakers using single wiring bi-wiring Bi-wiring is performed in the same way as single wiring except that, for each speaker, a pair of cables are used to connect the amplifier to each speaker.
