SAFETY GUIDELINES This appliance was produced under strict quality controls. It complies with all established international safety standards. Nonetheless, the following instructions should be fully read and observed in order to prevent any hazard: Do not open the appliance! Risk of electric shock! 7/3 \ There are no parts in the appliance that require maintenance bythe user. / Maintenance/Alterations All equipment that is connected to the domestic mains voltage can be dangerous to the user if not handled properly. Leave maintenance work to qualified profes- sionals. The product is only permitted for connection to AC 230Voli/50Hz, for earthed sockets and use in enclosed areas. Altering the product or manipulating its serial number voids the warranty. Afer a fault, leave the appliance‘s fuse to be replaced only by a professional with one of the same kind. Power Cable Connection Always pull the plug and never the power cable if you want to disconnect the appliance from the mains power. Make sure when setting up the appli- ance that the power cable is not squashed, severely bent or damaged by sharp edges. Do not touch the power lead with wet or damp hands. Use the power cable supplied or another one from Vincent. Switching Off Switch the appliance off every time before you con- nect or remove ofher components or loudspeakers, disconnect or connect it to the mains power, leave it unused for a longer period or want to clean its outsi- de. On all amplfiers and receivers, wait approx. minute after this before disconnecting or reconnecting the cable. Moisture/Heat/Vibration Contact of electrically operated equipment with liquids, moisture, rain or water vapour is dangerous for such equipment and the user and must be avoi- 24 Vévcent ded without fail. Take care that no liquids or objects get inside the appliance [ventilation slots etc.] lt must be disconnected from the mains power imme- diately and examined by a professional if this hap- pens. Never expose the appliance to high tempera- tures (direct sunshine] or strong vibration. Heat Build-up All amplifiers generate heat as part of their design. Make sure that a gap of 5 cm remains around the appliance and that the surrounding air can circula- te (do not install in enclosed cupboards). Vents must not be covered up. Volume The maximum tolerable volume is always reached well below the maximum possible seing on the amplifier. Be careful with the volume setting, therefore, in order to prevent damage to hearing. So that you do not expose yourself to high volumes unintentionally, always set to a low level before changing the input channel Cleaning Pull out the power plug before cleaning the outside of the product. Whenever possible, use a soft, lint- free cloth that has been dampened. Do not use abra- sives, solvents, thinners, flammable chemicals, polis hes and other cleaning products that leave marks. Batteries 22 Take note of the instructions for using batteries in the chapter "Remote Control". Setting up the appliance How the system is set up has an effect on the sound quality. Therefore only place it on a suitab- le, stable surface. To make the most of your system's sound quality, we recommend placing the equipment on Vincent racks and not putting them on top of each other.

The signals of the inputs "BALANCED" and "NES" are not available for recording at this output! PRE OUTPUT: Preamplifier Output IFone of the inputs "LINE1"..."LINEA" (10) or the input "BALANCED" (12) is selected, the "PRE" output can supply two additional main amplifier channels with the preamplified stereo audio signal of the selected source. The output must not be connected to the neighboring power ampli- fier input "LINES MAIN INPUT" or to the high level input of another HiFi component. POWER CONTROL (12V) These jack connectors (3,5 mm) send and receive the signals for the standby control {(12V Trigger) AC power connector and fuse holder To establish the power supply, connect the plugs of the power cable to the device and to a 230V AC wall outlet. The small plastic housing beneath the plug opening holds the fuse. Refer to the security précautions. REMOTE CONTROL Point the front of the remote control directly at the front of the appliance, making sure there are no objects between the remote control and the appliance. The distance between the remote control and the appliance should not be more than 7 m, as the reliability of the remote control is affected beyond this range. Make sure that you do not point the remote control at an angle to the appliance, as beyond an angle of +30° to the centre axis the appliance may not respond as well to the remote control. Change both batteries if the distance at which the remote control can be used effectively decreases. BATTERIES Using batteries Handling batteries incorrecily can cause battery acid to escape or an explosion in extreme cases. The batteries must be correctly inserted taking note of the polarity, which is marked in the inside of the battery compartment. In order to make full use of the batteries’ life, do not mix new and used batteries. Make sure that you insert batteries of the same type Some batteries are rechargeable, others are not however. Take note of the precautions and instruc- tions that are included on all batteries. Remove the batteries if the remote control is not going to be used for a long time. Under no circumstances must batteries be short-cir- cuited, taken apart or heated up. For environmental reasons, used batteries should be disposed of in accordance with local environ- mental regulations and not put with domestic waste Only use AAA (LR3) size batteries. Changing/Inserting batteries a) Open and remove the battery compartment lid of the remote control by tugging sharply on the fishpla- te on the edge of the remote control.

RCA connections Mechanically identical RCA plugs are available for input and output connections. Make sure that you do not get these connections confused during installation! Make sure that you do not mix up the analogue inputs for right and left. The RCA plugs for these are mosily colour coded as follows: red for the right channel, black or white for the left channel Contacting the middle pin of the RCA plugs with the outer ring of the RCA chassis jack may lead to damages to the main amplifier if it is switched on! To avoid this hazard, connect or disconnect only in switchedroff state and more than one minute after deactivatingl

DURING INSTALLATION PLEASE OBSERVE

THE FOLLOWING ADVICE: Speaker cable connections The use of ready-made loudspeaker cables is re- commended instead of connecting the cable's cen- tral wire {strand) directly to the terminals. Banana plugs or cable lugs ensure high security from short- circuits and damage to loudspeakers or amplifier. Ensure that bare loudspeaker wires are never able to come into contact with each other or with the metal on the back of the housing. Ensure that bare loudspeaker wires are never able to come into con- tact with each other or with the metal on the back of ihe housing. Make sure that the positive and negative loudspea- ker wires are connected correcily. You will notice a reduced sound quality if the connections are the wrong way round. Only use loudspeakers with a nominal impedance of at least 4Q Cable connections Make sure that all plugs fit tighily. Inadequate con- nections can cause noise interference, failures and malfunctions. TC Te me - falsely- right To make the most of the components’ sound poten- fial, only high quality loudspeakers and connecting cables, for example Vincent cables, should be used. Your local stockist will be glad to advise you about this. Vincent 8

CONNECTION OF THE SOURCE EQUIPMENT WITH

RCA HIGH LEVEL OUTPUTS

Connect the outputs of these source devices with the inputs "LINE1"."LINEA" (10) of the amplifier. The output sockets on the source equipment are usually indicated by "Line Out", "Audio Out" or "Front Out". You will find information about ways to connect source equipment in their operating manuals. To use a record player you need a so-called equaliser preamplifier (also called a phono pream- fs) plifier], which is installed in the signal path between the record player and one of the high-level inputs. Some models of record player already include this preamplifier and can be connected directly. You will find further information in this appliance’s operating manual. The stereo sound of appliances that use output connectors ofher than RCA [DIN plugs, jack plugs] can often also be used with the aïd of adaptors. Up to four high level stereo sources can be connected to these RCA inputs. The audio inputs "LINE1"..."LNEA" (10) represent electrically equivalent standard high level inputs with RCA connection They have an identical function and differ only in name. UE ue ue mu] RCA connection CD-Player, Tuner, DVD-Player, etc oo: LINE OUT CONNECTION OF ONE AUDIO SOURCE WITH XLR OUTPUT The "balanced" input can only be connected to a device equipped with symmetrical output. At the sour- ce device you can recognize it by the three-pin XLRtype of the output jack. Leave the XLR input of your pre-amplifier open if none of your audio sources uses this. Sometimes both types of output connectors are provided XLR connection SV234 e.g. CD-Player 32 Vévcent CONNECTION OF A STEREO PREAMPLIFIER OR THE

FRONT CHANNELS OF A MULTI-CHANNEL SYSTEM

This stereo amplifier is equipped with a main amplifier input (LINE5"), also known as "unity gain input" Input signals to this bypass the internal preamplifier stage and are treated as preamplifier output signals. That is why this amplifier can accept the output signals of a preamplifier or the front channel preamplifier outputs of a home cinema system (AV receiver or AV preamplifier). Volume control as well as Balance and Muting can not be achieved at the SV-234 when using the input "LINE5". These functions must be opera- ted at the device connected to this input. RCA connecion (us) © sure proampiier HO) OUTPUT SV234 RCA connection Ê = TIRE" ANALOG AUDIO OUTRUT Ithe input "LINE5" has been selected, the amplifier SV:234 acts like a stereo power amplifier. l£ you want the amplifier SV-234 to automatically switch on/off every time the HiFi component connected to "LINE5" is switched on/off, the power control cable connections subsequently described must be applied. Please leave the input connector "LINE5" unused if you do not wish to use the amplifier SV-234 just as a power amplifier.

CONNECTIONS FOR THE STANDBY CONTROL

(POWER CONTROL) Many AV.Systems consist of a multitude of individual components. To avoid the necessity of switching them on and off before and after every use, many manufacturers have equipped their devices with what is known as "POWER CONTROL" circuit or "TRIGGER". This kind of remote-controlled standby circuit is used primarily for preamplifier and power amplifiers. To employ these functions, direct or indirect cable connections must be made between the preamplifier (or integrated amplifier) and all the devices which support this function. The “POWER CONTROL" function operates in such a way that each switching on or off of one device in the system (usually the preamplifier) automatically brings about the switching on or off of all the connected devices which support this function. Please keep in mind that all devices which respond to the power control are not disconnected from the mains network when switched off. They are set to a standby state instead. For connecting cables, two-core cables with 3.5 mm jack plugs (mono) are used. For each connection between two devices one of those cables is needed Vincent 33

IF you don't wish to use this function or if the other components do not support it, all you have to do is leave out these cable connections. The SV-234 is equipped with one input connector and two output connectors for the power control. As a result, this amplifier can supply and transmit the switching signal for other components in the system as well as accept it from other components. Bofh cases are described in the following. (1) The complete system is to be switched on/off at the SV-234 POWER button In this situation the input in the terminal "POWER CONTROL" (15) must not be occupied and must be left open. Two HiFi components that are able to react to the power control signal can be connected directly to the amplifier's power control outputs. If more than two devices, which can be controlled, are to be con- nected, then it is necessary, to make the power control connection between the preamplifier and these furt- her devices through the outputs of the two devices which are connected directly. For that reason, every HiFi component that accepts power control signals is also equipped with a power control output. Thus, in theory it is possible to provide an infinite number of HiFi components with the power control signal. This approach, to loop a signal through a chain of components, is commonly referred to as "daisy chaining". SV-234 je | ES CICR (o ©] «6 moin ompitier 550 ) (2) The SV-234 is intended to react to the trigger signal If, for example, two output channels of a preamplifier are connected to the main input "LINE5", if this HiFi component can supply a power control signal and if you want the amplifier SV-234 to switch on/off synchronously with the component attached to "LINE5", one power control output of this component must be connected to the input in the SV-234 terminal "POWER CONTROL" [15]. The connector at the sourcing HiFi component may as well be labelled with "TRIGGER OUTPUT". Both power control outputs of the SV.234 can additionally be used to forward the received switching signal to other components of your system. to o| | e.g. AV preamplifier 34 Vévcent Many devices which can be controlled by a switching signal (not preamplifiers or integrated /_2 \ amplifiers}, have two terminals which do not differentiate between input and output. In this case either of the two can be selected. "POWER CONTROL" sockeis of preamplifiers or integrated amplifiers must not be interconnec- tedl AIl receiving devices must not be connected to more than one preamplifier or integrated amplifier (directly or indirecily)!

CONNECTION OF A RECORDING DEVICE

If you want, you can use the RCA sockets "REC OUTPUT" [13) on the back of the appliance to connect an analogue stereo recording device {e.g. CD recorder, cassette recorder etc.) or another appliance that is intended for receiving the unchanged, fixed stereo output level [line level) from the signal source selec- ted on the amplifier at any given time. The output level is independent from the volume setting but reacts to the "MUTE" command. N came SV234 RCA connection UNE IN Connect this signal output to the signal input ("LINE IN", "TAPE IN" oder "REC IN] on the recording appli- ance using RCA cables. Please note that some recording equipment can have a slighily detrimental effect on the audio signal quality. Some recording devices have rather low input impedance, which can slight- ly alter the input signal voltage. For maximal music enjoyment we recommend that you connect to the “REC” terminal only for as long as the recording is actually being made CONNECTION OF TWO ADDITIONAL MAIN AMPLIFIER CHANNELS You only need the "PRE OUTPUT" sockets [14) if you want to use a separate stereo amplifier or 1wo mono amplifiers to supply two additional loudspeakers. This makes sense if you intend to use 1wo more loud- speakers for stereo music playback, for example in a separate zone [another room of your home]. These loudspeakers are then connected to the speaker outputs of the additional amplifier(s]. The amplifier out- put connections "PRE OUTPUT" (14) must be connected with the input connectors of the main amplifier, in most cases labelled "INPUT", "POWER AMP IN" or "MAIN INPUT".

Either a single speaker pair [A] or two speaker pairs (A+B) can be connected to the SV:234 amplifier Both outputs are identically provided with the stereo signal of the currently selected input source. For each loudspeaker you will find iwo connector screws [positive + und negative -) at the amplifier's backside One side of the speaker cable must be attached here. Each pair of screws has a label "R or "L' nearby to clarify to which stereo channel it belongs. At the loudspeaker connection terminal there are similar con- nector screws or connectors. There, the polarity of each screw {+ or -| can be identified as well and the other side of the speaker cable associated with this speaker must be attached. Make sure only connector screws of the same polarity will be connected by each speaker cable wire: a knob marked "+" in the amplifier's terminal must be connected with a speaker's connector screw marked "+" as well. Our sketch shows all connections necessary for one pair of speakers. If a second pair of loudspeakers is intended to be used, the connector screws of the lower row [Speakers B} must be connected in a similar fashion to the additional speakers’ input connectors. If every speaker is connected in a conventional way [a fwo core speaker cable for each loudspeaker) and you own loudspeakers that are equipped with Bi Wiring terminals [four connector screws] you have to make sure that the metal brackets [contact pieces consisting of small metal plates or short pieces of cable which are supplied with the speakers) are applied to the terminal and that each one connects the two knobs of the same polarity (e.g. both connectors marked "+"]. The connector screw labelled "+" and "R!' at the ampli- fier's backside must be connected to one of the bridged, labelled "+" connectors of the loudspeaker assi- gned to the right stereo channel. Accordingly, the connector screw labelled "-" and "R" at the amplifier's backside must be connected to one of the bridged, labelled "-" connectors of the loudspeaker assigned to the right stereo channel. Connect the left side loudspeaker in the corresponding way. If you are using ready made loudspeaker cables with 4 mm banana plugs, all you need to do is connect the two plugs on each loudspeaker cable end to the two associated speaker connectors. Turn the connec- tor screws clockwise to fasten them. 36 Vévcent IF you want to use speaker cables equipped with spade lug connectors, every connector screw must be opened by turning counterclockwise. After that, the lug must be moved under the screw head. Then, turn the screw clockwise to fasten the lug to the connector. To avoid damages to the amplifier, make sure the connection is fight and no bare metal from the cable lug connector makes contact with the rear panel or with another terminal a dm = If no connector is to be used, remove approximately 1 cm length of insulation from each end of the spea- ker wire. Twist the brad in order to avoid short circuits. Turn the fastener on the loudspeaker terminal coun- terclockwise to loosen it and introduce the bare wire end into the exposed connector hole. Then turn the fastener clockwise so that the wire is firmly clamped. Make sure the connection is pretty tight. IF you intend to connect two pairs of speakers, all loudspeakers must have a nominal impedance of at least 80. If only one pair of speakers is used [A or B], all types of loudspeakers with a mini- mal nominal impedance of 4Q can be uiilised. Consider correct polarity, the positive contact is mosily marked red or with "+". The side of the speaker cable that has to be connected with the positive socket has a marking.

CONNECTION OF THE POWER CABLE

Check whether the wall socket provides the appropriate mains power, which is the case if it is supplied with 230 V AC 50 Hz. Push the plug on the power cable supplied firmly into the power socket [16] on the back of ihe appliance. Plug the other end of the power cable into a mains socket Vincent 37

Burn in/ Warm up Your audio components need a certain time period until they reach maximum performance. The duration of this "warm up" time is very diffe- rent for the various elements of your audio system. Higher and homogeneous sound quality is achie- ved while keeping the device switched on. Your audio specialist dealer has enough experi- ence to give you more information. Net frequency noise Some audio source devices may in combination with the amplifier cause a humming noise at power line frequency audible from your speakers. Usually, its volume varies with the volume setting of the amplifier. This is no sign of a defect or fault of your audio products but has to be eliminated. Generally, every wallpowered device connected to the ground wire of the power plug can cause this problem when connected to the amplifier. Experience shows that this problem is mainly cau- sed by antenna-connected components {as TV.sets or Tuners), personal computers, electrostatic loud- 40 Yércent speakers, subwoofers, record players or headpho- ne amplifiers that are connected to the audio inputs of the amplifier. Another possible reason for humming noise is electromagnetic interference of other components’ power supplies with pick-up- systems of record players (change the place ofthe record player for a tesi]. In most electric devices the ground potentials of all signals are connected to each other at one central point, where they have one common connection IF the device uses the protective conductor of the wall outlet, the corresponding wire of the line cord is connected intractably to the metal housing of the device. This is the mosily the point where the central grounding point is attached to. By doing this the housing is able to shield all signals from external radiated noise. Some main amplifiers are equipped with a "Ground Li"-switch. If it is acti- vated, ground potential of the chassis and the pro- tective ground wire are being separated from the central signal ground point. The protective ground wire keeps its function. Sometimes this helps pre- vent noise caused by errors in grounding. IF the problem occurs and cannot be solved by yourself your audio specialist dealer will help you

This includes CD players, DVD players, tuners (radios), cassette play- ers, DAT recorders, personal computers, record players, portable audio devices and many more Input sensiti Term for the smallest average (RMS) input voltage which causes the maximum output power at the maximum volume setting on the amplifier. Examples: 100 mV to 500 mV {Millvolts} on high level inputs, 2 mV to 5 mV on the phono MM input or 0.1 mV to 0.5 mV on the phono MC input. ity dB-Level This is a way of describing any physical quantity; it is a common measurement for signal voltages and the volume. lt is given in decibels (dB). Alternating signal voltages below 1V (RMS) are described as "line level" voltages, which are suitable as music signals for amplifier inputs. Inputs on amplifiers {mosily represented by RCA sockets), which are designed for signals on the CD player, tape recor- der, DVD player etc. are also referred to as “line level inputs" or "highevel inputs". Those signal inputs must not be confused with inputs that accept preamplified signals. RCA RCA is the American name for coaxial RCA connec- tors and sockets, originally the abbreviation for "Radio Corporation of America", the name of a United States company. Both the plug and cable consist of a rodshaped inner lead and a cylindri- cal-shaped outer lead. This enables a mono audio signal or a video signal to be transmitted. Compared to the XLR plug connector, this type of connection is also called "unbalanced signal con- nection" XLR Also: "Symmetrical Connection" or "balanced' A plug-and-socket connection for audio devices. lt is round {with approx. 1.5 cm in diameter) and has 3 contacts/pins. XLR is an alternative connecti- on to RCA used to transmit NF-Signals in professio- nal audio equipment. The advantage is one additio- nal transmission path for the same but phase inver- ted signal. IF the receiving device can process this, all inducted noise received in the cable screen can be eliminated. The signal voltage level used for this type of transfer is higher, so it is a more robust less sensitive signal path. Vincent 43
