User manual ARCAM FMJ A18

[. . . ] A18 Handbook Integrated amplifier english class ii product This equipment is a Class II or double insulated electrical appliance. It has been designed in such a way that it does not require a safety connection to electrical earth (`ground' in the U. S. ). safety guidelines CAUTION: To reduce the risk of electric shock, do not remove cover (or back). WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated `dangerous voltage' within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] Plug the other end of the cable into your mains socket and, if necessary, switch the socket on. interconnect cables We recommend the use of high-quality screened cables that are designed for the particular application. Other cables will have different impedance characteristics that will degrade the performance of your system (for example, do not use cabling intended for video use to carry audio signals). It is good practice when connecting your equipment to make sure that the mains power-supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals. e-5 english A18 connections Speaker terminals See page 8 for information on connecting loudspeakers. Phono earth terminal For connecting your turntable earth lead, if required. Note that this terminal must not be used as a safety earth. Aux input Analogue 3. 5mm stereo jack socket, intended for connecting a portable MP3 player. Power inlet Connect the correct mains cable here.

See page 8 for more information. Audio connections audio inputs, although any suitable device may be connected to the line-level inputs. (Note, however, that the name of the input shown on the front-panel display cannot be changed. ) DVD, SAT, TUNER and CD PHONO Phones 3. 5mm stereo jack socket, intended for use with a set of headphones. In addition to the line level inputs, the AV and PVR connectors both have line level outputs for use in recording from other sources. If you have already an external phono amplifier that you wish to use, connect its output to one of the line-level inputs. e-7 english 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. 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 lowfrequency terminals to those for the higher-frequencies; this mUST NOT Be RemOVeD in a single-wired system. 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. < 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-amping, please contact your Arcam dealer who will be happy to help you. loudspeakers An A18 connected to speakers using single wiring bi-amping Bi-amping is the separation of the amplification of lowand high-frequency signals over two amplifiers. Normally, your A18 is used to drive the highfrequency (treble) speakers, with a P38 used for the lower (bass) frequencies. Connect your A18 to the speakers as described for single wiring, with the exception that the A18 should be connected to the speaker terminals labelled hf or `High Frequency'. Then connect the power amplifier (an Arcam P38 for example) to the Lf or `Low Frequency' terminals, as in the diagram. [. . . ] In each case, the source is selected from the input sockets with the corresponding name. Muting output The output of the A18 can be silenced by pressing Mute on the front panel (or - on the remote control). Press Mute/- for a second time (or change the volume) to cancel mute. bass This setting allows you to increase or decrease the level of low frequency elements in the sound within the range +7 to -7. Treble This setting allows you to increase or decrease the level of high frequency elements in the sound within the range +7 to -7. direct mode This is a `tone defeat' setting which ignores any Bass and Treble trim values. Press drct (Direct) on the remote control to toggle this setting; `DIRECT' is lit on the display when Direct mode is active. e-10 troubleshooting no sound Check the following: < The A18 amplifier is powered up and switched on. < The selected source is generating audio (e. g. , if CD is selected, then the CD is playing).
