Do not open the appliance! Risk of electric shock!

There are no parts in the appliance that require maintenance by the 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 professionals. The product is only permitted for connection to AC 230Volt/50Hz, for earthed sockets and use in enclosed areas. Altering the product or manipulating its serial number voids the warranty. After 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 appliance 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 connect or remove other components or loudspeakers, disconnect or connect it to the mains power, leave it unused for a longer period or want to clean its outside. On all amplifiers and receivers, wait approx. 1 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-

ded without fail. Take care that no liquids or objects get inside the appliance (ventilation slots etc.).

It must be disconnected from the mains power immediately and examined by a professional if this happens. Never expose the appliance to high temperatures direct sunshine or strong vibration.

Heat Build-up

Make sure that a gap of 5 cm remains around the appliance and that the surrounding air can circulate (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 setting 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 abrasives, solvents, thinners, flammable chemicals, polishes and other cleaning products that leave marks.

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 incorrectly 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 instructions 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-circuited, taken apart or heated up.

For environmental reasons, used batteries should be disposed of in accordance with local environmental 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 fishplate on the edge of the remote control. The battery compartment lid is held in place magnetically, there is no need to loosen the screws!

24. Input selector buttons

Select the input source you want to listen to with these buttons.

25. DIMMER: tube illumination setting

This setting affects the brightness of the illumination of the tube display window (3).

These buttons change the amplifier's volume setting for the speakers and the preamplifier output (12).

INSTALLATION

Set up the cable links in a sequence as follows. Connect the power cable between device and power supply only after all other connections have been made.

DURING INSTALLATION PLEASE OBSERVE THE FOLLOWING ADVICE:

Protective caps

Prior to the first installation the protective plastic caps must be removed from all the connections used at the rear of the unit.

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 mostly 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 switched-off state and more than one minute after deactivating!

Speaker cable connections

The use of ready-made loudspeaker cables is recommended instead of connecting the cable's central wire (strand) directly to the terminals. Banana plugs or cable lugs ensure high security from short-circuits and damage to loudspeakers or amplifier.

Make sure that bare loudspeaker wires never come into contact with each other or with the metal on the back of the housing.

Make sure that the positive and negative loudspeaker wires are connected correctly. 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 8 (if two pairs of loudspeakers are connected) and a nominal impedance of at least 4 (if one pair of loudspeakers is connected).

Cable connections

Make sure that all plugs fit tightly. Inadequate connections can cause noise interference, failures and malfunctions.

- falsely - right -

To make the most of the components' sound potential, 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.

CONNECTION OF THE SOURCE EQUIPMENT

Connect the outputs of the source appliances to the inputs (14) of this 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 phono preamplifier (also called an equaliser pre-amplifier), 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 other than RCA (DIN plugs, jack plugs) can often also be used with the aid of adaptors.

You can connect up to five devices with analogue RCA stereo high level output such as a CD player in order to provide the audio signals of your input sources to the system. All six inputs represent electrically equivalent standard high level inputs with RCA connection. They have an identical function and differ only in name.

CONNECTION OF A RECORDING DEVICE

If you want, you can use the RCA sockets "REC OUT" (17) 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 selected on the amplifier at any given time. The output level is independent of the Volume setting, the Loudness function and the Tone control (BASS, TREBLE, TONE). Please note that while the preamplifier is muted (18) the recording output is switched off.

graph LR
    A["SV-737"] --> B["RCA connection"]
    B --> C["LINE IN"]
    C --> D["Recording device, e.g. tape recorder"]

Connect this signal output to the signal input ("LINE IN", "TAPE IN" or "REC IN") on the recording appliance using RCA cables. Please note that some recording equipment can have a slightly detrimental effect on the audio signal quality. Some recording devices have rather low input impedance, which can slightly 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 AN EXTERNAL PREAMPLIFIER OR EXTERNAL POWER AMPLIFIER

On the SV-737 you have the possibility to split the preamp and the poweramp. If you want to use the SV-737 as power amplifier only, please remove the bridges of the connections PRE / MAIN (16). After that you can connect your external preamplifier to the connector "MAIN".

SWITCHING THE VOLTAGE

This device is equipped with a switch (21) that can be used to change the country-specific voltage from 230 V to 110 V.

Please never actuate the switch during operation! The voltage must only be switched by a technician, since the device fuse must also be replaced after actuation of the switch! Information about the device fuse can be found on the back of the device.

Unauthorised actuation of the switch will void any warranty claim!

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. Particularly for preamplifiers and main amplifiers this kind of remote standby control is utilized, as power amplifiers are often placed far from other devices near the speakers. 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.

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-737 is equipped with two output connectors for the power control. Here, the switching signal generated by the amplifier is available for other components of the system. Two HiFi components that are able to react to the power control signal can be connected directly to the amplifier's power control outputs (20). If more than two devices, which can be controlled, are to be connected, then it is necessary to make the power control connection between the amplifier and these further 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".

CONNECTIONS FOR THE STANDBY CONTROL (POWER CONTROL)

Many devices which can be controlled by a switching signal (not preamplifiers or integrated amplifiers), have two terminals which do not differentiate between input and output. In this case either of the two can be selected.

"POWER CONTROL" sockets of preamplifiers or integrated amplifiers must not be interconnected! All receiving devices must not be connected to more than one preamplifier or integrated amplifier (directly or indirectly)!

CONNECTION OF HEADPHONES

A set of headphones equipped with a 6.3 mm jack can be plugged into the socket "PHONES" (12) on the front of the appliance.

SV-737

By doing this, the loudspeakers are switched off. All headphones with an impedance of between 32 Ohm and 600 Ohm may be used. Unsuitable headphones with too low impedance may damage the amplifier or produce such unexpectedly loud volume that your hearing may be damaged. The volume should be reduced for safety reasons before a set of phones is connected.

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 (19) on the back of the appliance. Plug the other end of the power cable into a mains socket.

CONNECTION OF THE LOUDSPEAKERS

Either a single pair of loudspeakers or two speaker pairs can be connected to the amplifier SV-737. Both stereo outputs are identically provided with the signal of the currently selected input. For each loudspeaker you will find two 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 connector 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 must be connected in a similar fashion to the additional speakers' input connectors.

Right and left loudspeaker

If every speaker is connected in a conventional way (a two 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 amplifier's backside must be connected to one of the bridged, labelled "+" connectors of the loudspeaker assigned 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.

CONNECTION OF THE LOUDSPEAKERS

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 connector screws clockwise to fasten them.

IMPEDANCE (4-80) SPE R SPE

If you want to use speaker cables equipped with spade lug connectors, every connector screw must be opened by turning counter clockwise. 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 tight and no bare metal from the cable lug connector makes contact with the rear panel or with another terminal.

If no connector is to be used, remove approximately 1 cm length of insulation from each end of the speaker wire. Twist the braid in order to avoid short circuits. Turn the fastener on the loudspeaker terminal counter clockwise 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.

IMPRESANCE (MO) SPE SPE

If you intend to connect two pairs of speakers, all loudspeakers must have a nominal impedance of at least 8 Ω. If only one pair of speakers is connected, all types of loudspeakers with a minimal nominal impedance of 4 Ω can be used.

Consider correct polarity, the positive contact is mostly marked red or with "+". The side of the speaker cable that has to be connected with the positive socket has a marking.

Your audio components need a certain time period until they reach maximum performance. The duration of this "warm up" time is very different for the various elements of your audio system. Higher and homogeneous sound quality is achieved while keeping the device switched on.

Your audio specialist dealer has enough experience 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 wall-powered 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 caused by antenna-connected components (as TV-sets or Tuners), personal computers, electrostatic loudspeakers, subwoofers, record players or headphone 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 of the record player for a test).

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.

TIPS

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 mostly 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 Lift"-switch. If it is acti-

vated, ground potential of the chassis and the protective ground wire are being separated from the central signal ground point. The protective ground wire keeps its function. Sometimes this helps prevent noise caused by errors in grounding.

If the problem occurs and cannot be solved by yourself your audio specialist dealer will help you.

GLOSSARY

Audio Sources/Source devices

These are the components of your HiFi system and all other appliances, whose sound you want to hear over the system and are thus connected to the pre-amplifier, amplifier or receiver. This includes CD players, DVD players, tuners (radios), cassette players, DAT recorders, personal computers, record players, portable audio devices and many more.

dB Level

This is a way of describing any physical quantity; it is a common measurement for signal voltages and the volume. It is given in decibels (dB). Alter na ting signal voltages below 1V (RMS) are described as "line level" voltages, which are suitable as music signals for amplifier inputs. Inputs on amplifiers (mostly represented by RCA sockets), which are designed for signals on the CD player, tape re corder, DVD player etc. are also referred to as "line level inputs". Those signal inputs must not be confused with inputs that accept preamplified signals.

Dynamic

The volume difference between the quietest and the loudest sounds possible in audio signals (with -out distortion or transition to noise). Dolby-Digital and DTS soundtracks allow very high dynamics and produce excellent cinema-like effects.

Input sensitivity

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 (Millivolts) on line 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.

RCA

RCA is the American name for a type of coaxial connectors 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 rod-shaped inner lead and a cylindrical-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 connection".
