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! 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 5cm 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.

Batteries

Take note of the instructions for using batteries in the chapter "Remote Control".

DESCRIPTION OF THE APPLIANCE

Despite the fact that development is constantly moving in the direction of digital audio format and towards audio video systems with an increasing number of channels, high quality stereo systems still enjoy a large degree of popularity. Recent trends also have not brought any changes concerning the advantages of separate pre-/main amplifier systems over integrated amplifiers.

For the precise, authentic reproduction of recorded music as it is demanded from high end pre-amplifiers the following three properties play a prominent role: the mechanical construction, the structure of the internal electrical power supply and the design of the amplifier circuitry (signal paths, electromechanical components). The pre-amplifier SA-94 has been forged using this knowledge without compromises. The SA-94 is a remote controllable stereo preamplifier for up to six music sources from the Vincent product range. The housing has been chosen to be a solid aluminum chassis. The internal electrical power source contains two oversized ring core transformers. Both stereo signal paths are routed separately from the source inputs to the preamplifier outputs. Even unsymmetrical input signals (e.g. from an

RCA connected CD player) are being transformed into balanced signals to make use of the symmetric pre/main amplifier connection. The result of extensive development effort and component selection is a preamplifier that not only is unrivalled in sound quality in its class but keeps control over main amplifiers and loudspeakers in the most diverse situations. A special feature compared to its predecessor SA-93Plus is the integration of POWER CONTROL capabilities (standby control signal output). High-quality craftsmanship and an outstanding ratio in price/performance can be taken for granted.

This preamplifier is also the ideal partner for Vincent main amplifiers like SP-994, SP-995 or multi channel amplifiers like members of the SAVP series. It is an excellent choice to add DVD players, CD players, tuners, headphone amplifiers and loudspeakers from the Vincent range. A remarkable result is achieved when combining Vincent amplifiers with Focal loudspeakers. In combination with the HiFi furniture and speaker cables from the Vincent range, one can build a perfectly harmonious system.

FRONT VIEW

1. POWER

This is the main power switch for turning on and off the device. The preamplifier is separated from the mains voltage when switched off and cannot be set into a standby state.

2. MUTE

Press this button to mute your system's loudspeakers as an effect of muting the signals of the pre-amplifier output "OUTPUT" (9), and the recording output "REC OUTPUT" (8).

3. Sensor diode for the remote control

4. Display

In normal use the display shows the name of the selected input and the volume setting. As long as

adjustments are being made (e.g. to MUTE, BALANCE, GAIN), the relevant values are presented.

5. Input selector keys

With a touch on one of these buttons you choose for playback one of the audio sources attached to the corresponding connectors at the amplifier's backside (7).

6. VOLUME / : Volume keys

These are the keys for the adjustment of the main volume level of the system. They consequently control the signal of the preamplifier outputs "OUTPUT" (9).

7. INPUT: Terminal for stereo audio signals of the source equipment

Here you find six stereo inputs for source equipment (5x RCA, 1x XLR) with analogue stereo (line level) audio output.

8. REC OUTPUT: Output connectors assigned to a recording device

If desired, you can connect a recording device like a CD recorder or a tape recorder to this output. The stereo signal of this output is identical to the output signal of the selected audio source at one of the preamplifier INPUTs and it is independent of VOLUME control, BALANCE setting and GAIN function. The signal from the XLR source is not available at the recording output! As long as the preamplifier is muted (2)(12), the "REC OUTPUT" does not give the music signal.

9. OUTPUT: preamplifier outputs (1xXLR, 2xRCA)

With these three pairs of connectors you can connect the preamplified stereo audio signal of the currently selected source to the power amplifier channels. All RCA and XLR outputs may be used at the same time. The VOLUME, BALANCE, MUTE and GAIN settings have effect on the signal at this output.

10. POWER CONTROL: ON/OFF control

These jack connectors (3.5 mm) provide the on/off signal for the standby control (12V Trigger).

11. Power Connector with Fuse holder

To establish the power supply, connect the plugs of the power cable to the device and to a suitable wall outlet. The small plastic housing holds the fuse. Refer to the security precautions.

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 7m 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!

b) If necessary, remove used batteries and insert new ones correctly as shown by the diagram in the battery compartment.

c) Put the compartment cover back on and close the battery compartment.

BUTTONS OF THE REMOTE CONTROL

12. MUTE

Pressing this button once cuts the signals at the outputs "OUTPUT" (9) and "REC OUTPUT" (8) so that the system's loudspeakers are muted. Pressing it again returns to the original volume.

13. BAL-L und BAL-R

Both keys can be used to change the volume difference between right and left speaker if that is desired.

14. Input selector keys

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

15. GAIN:

-8dB attenuation of the output signal

With the activation of this function, the output signal (9) is reduced by 8 dB and thus the volume of the attached speakers. It should only be activated if even at low volume settings the volume is already very high.

16. LEVEL /

These buttons change the amplifier's volume level for the preamplifier outputs "OUTPUT" (9).

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 analogue and digital outputs. Make sure that you do not get these connections confused during

installation!

Make sure that you do not mix up the analogue connectors 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!

Cable connections

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

To make the most of the components' sound potential, only high quality loudspeaker cables and connecting cables, for example Vincent cables, should be used. Your local stockist will be glad to advise you about this.

XLR connections

Please note that European and US-American XLR signal assignments for the connector pins are different. This Vincent preamplifier uses the European system following the standard AES14-1992. The cable structure is the same in any case. As long as both the preamplifier and the power amplifier satisfy the same standard, the signal connection is correct. This is always the case if both units were made by Vincent. If two units from different standards are connected, this inverts the signal. In this case the signal assignment on one side of the connection has to be changed. Your audio specialist dealer will support you with this.

1.US System (Pin 2 = COLD, Pin 3 = HOT)

1. European System (Pin 2 = HOT, Pin 3 = COLD)

Bear in mind that the signals into the "balanced" inputs (XLR) are not being transferred to the REC-Output (8). For example, it is not possible to make a recording from a CD-Player connected to one of these inputs using the recording output (8)!

CONNECTION OF THE SOURCE EQUIPMENT WITH RCA OUTPUT

Connect the outputs of the source appliances to the inputs "LINE1"..."LINE5" (7) of this preamplifier. 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.

General information:

To use a record player you need a so-called phono preamplifier (also called an equaliser preamplifier), 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 five RCA inputs represent electrically equivalent standard high level inputs with RCA connection. They have an identical function and differ only in name.

CONNECTION OF THE SOURCE EQUIPMENT WITH XLR OUTPUT

The input "BALANCED" (7) can only be connected with audio devices that own a balanced output connector, too. Leave the input free if none of your audio sources uses this kind of connectors. Sometimes audio source devices have the option of using either of these connection standards.

CONNECTION OF A RECORDING DEVICE

If you want, you can use the RCA sockets "REC OUTPUT" (8) 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 to receive 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 level, the channel BALANCE and the GAIN function. The input signals at the XLR connectors can not be obtained at the recording output (8) and thus can not be used as a source for recordings. Please note that while the preamplifier is muted (2)(12) the recording output is switched off.

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.

Check that the electricity supply to your home is appropriate to the device. The required voltage and frequency can be read on the back of the device beside the socket for the mains. If the electricity supply is appropriate, push the inlet connector of the supplied mains cable firmly into socket for the mains on the back of the device (11). Connect the other end of the mains cable to a mains socket.

CONNECTION OF ONE OR MORE POWER AMPLIFIERS

This preamplifier has two stereo preamplifier outputs with RCA connectors and one stereo preamplifier output with XLR connectors for the main amplifier channels. In this way it is possible to drive up to six loudspeakers (or bi-wire/bi-amp one pair of loudspeakers). The stereo music signal is transmitted at both RCA outputs (1, 2) as well as at the XLR output (BALANCED) at the same time. The main amplifiers supply the system's loudspeakers and the loudspeakers are connected to the outputs of these. You may use all outputs of this preamplifier at the same time. Instead of each stereo main amplifier shown here you can alternatively use two mono main amplifiers.

To connect one pair of loudspeakers you will need two main amplifier channels, for example one stereo main amplifier. One option is to connect both RCA "OUTPUT" (9) sockets named "1" with two main amplifier RCA input sockets (named "INPUT" or "POWER AMP IN"). For this you need RCA cables (supplied). In the case of XLR connection choose the output labelled "BALANCED". Please pay attention not to interchange right with left channels. The letters "R" and "L" indicate the correct correlation. You may further use the SA-94 preamplifier output marked with "2" for a headphone amplifier or an additional main amplifier.

If the main amplifier has an XLR input connector it should be preferred over the RCA input connector. In that case interconnect the XLR connectors named "BALANCED" (9) and the main amplifier input. Please pay attention not to interchange right with left channels. The letters "R" and "L" indicate the correct correlation.

The fact that this amplifier is equipped with two RCA stereo preamplifier outputs enables you to biamp your loudspeakers using adequate speakers and one or more additional main amplifiers. Your HiFi specialist will advise you on this.

CONNECTIONS FOR THE STANDBY CONTROL (POWER CONTROL)

Many AV systems or stereo audio 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 3.5mm 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 SA-94 is equipped with two output connectors for the power control. Here, the switching signal generated by the SA-94 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 (10). 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".

Attention:

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)!

OPERATING THE APPLIANCE

Operation	Button(s)	Description
Switch on and off	POWER (1)	The preamplifier is switched on and off using this button at the front panel. It has no standby option. When switched off the device is internally separated from the AC power. After switching on, the device needs up to four seconds before it is operational. As a precaution, after switching on, the volume setting of the preamplifier should be reduced.
Select an input	Input keys (5)(14)	A short touch on the button for the desired input channel ("LINE1"..."LINE5" or "BALANCED") changes to the playback of the audio source connected there. The front panel as well as the remote control carry those buttons. The name of the currently selected input channel appears in the display (4). Before switching over the input channel, the volume (6)(16) should be turned down as a precaution!
Change the volume	VOLUME▼/▲ (6)LEVEL▼/▲ (16)	Hold down the button "VOLUME ▲" or "LEVEL ▲" to turn up the volume. Use "VOLUME▼" or "LEVEL▼" to turn it down. This can be done on the remote control as well as at the amplifier front panel. The display (4) shows the currently selected Volume value. The minimum value is -99dB, the maximum Volume appears at latest with 00dB, for most speakers much below this value. The volume setting does not influence the signal at the "REC OUTPUT" (8).
Mute the preamplifier output	MUTE (2)(12)	The MUTE function can be activated or deactivated at the front panel as well as with the remote control. It switches off the preamplifier output "OUT-PUT" (9) and the recording output "REC OUTPUT" (8). Pressing one of these buttons again restores the volume to its original setting. For the time the preamplifier is muted the display (4) reads "MUTING".
Set the stereo balance	BAL-L/R (13)	One channel of the system (right or left) and thus one of the loudspeakers can be adjusted to be louder than the other one. That may be wanted if your favourite listening position in the room is closer to one speaker than to the other one resulting in a difference in perceived volume. Press, if necessary repeatedly, the button "BALL" to boost the left channel volume compared to the right channel volume. "BAL-R" can be used to boost the right channel volume. You are free to change the setting in 10 steps to each side (right or left). The maximum difference appears at the setting displaying "+10dB". While doing this, the display reads the current BALANCE value and the side (R: right or L: left) to which the BALANCE has been moved.
Reduce the amplifier's gain (attenuation 8dB)	GAIN (15)	Operating this key activates or deactivates an attenuation of 8dB, which is applied to the signal of the "OUTPUT" (9). The GAIN operation is useful, if the combination of amplifier and speaker is so sensitive that the usable region of the volume control of the SA-94 lies at the lowest values. In this situation the volume steps are too coarse. In this case, after first reducing the volume for the sake of caution, press the "GAIN" button. If the GAIN setting was "00dB" (normal) before, the display (4) now reads "-08dB". The perceived loudness is now reduced. One more key press to "GAIN" restores the original gain setting (00dB). The GAIN function can only be used via remote control and is not intended to be toggled in everyday use!

TIPS

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 different for the various elements of your audio system. Higher and more 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, subwoofer, 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 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. 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 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 activated, 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, FM tuners, cassette players, DAT recorders, personal computers, record players, portable audio devices and many more.

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: 100mV to 500mV (Millivolts) on line level inputs, 2mV to 5mV on the phono MM input or 0.1mV to 0.5mV on the phono MC input.

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). Alternating 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 recorder, DVD player etc. are also referred to as "line level inputs". Those signal inputs must not be confused with inputs that accept preamplified signals.

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".

Dynamics

The volume difference between the quietest and the loudest sounds possible in audio signals, without distortion or transition to noise.

XLR

Also: „Symmetrical Connection" or „Balanced". A plug-and-socket connection for audio devices. It is round (with approx. 1.5cm in diameter) and in most cases has 3 contacts/pins. XLR is an alternative connection to RCA used to transmit NF-Signals in professional audio equipment. The advantage is one additional transmission path for the same but phase inverted 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.
