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!
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 outsi-de.
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 avoided
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.
Batteries
Take note of the instructions for using batteries in the chapter „Remote
Control“.

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 the battery if the distance at which the remote control can be used
effectively decreases.
BATTERIES
Using battery
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.
The remote control for this item utilizes Lithium button cells. In case of old
appliance disposal put out this battery and dispose seperately!
- Open the battery compartmentof the remote control by pushingout the clip and pulling out the battery compartment.
- Remove the optionally used battery and correctly insert the new button cell, as schematically shown in the battery compartment.
- Close the battery compartment of the remote control.

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!
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
loudspeakers and connecting cables, for example Vincent cables, should be
used.
Your local dealer will be glad to advise you about this.
CONNECTION OF THE SOURCE EQUIPMENT
Connect the outputs of the source appliances to the inputs “S1”…”S6” (11)
of this preamplifier. You can connect up to six 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. 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. All six inputs represent electrically equivalent standard
high level inputs with RCA connection. They have an identical function and
differ only in name. To use a record player you need a so-
called phono preamplifier (also called a equaliser pream-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 other than RCA (DIN
plugs, jack plugs) can often also be used with the aid of adaptors.
CONNECTION OF SOURCE DEVICES OVER OPTICAL IN AND COAXIAL IN
The integrated D/A converter makes it possible to receive also digital audio
signals via an optical and/or coaxial cable and to transmit them analogously
to the amplifier. Here, the “Optical IN” and “Coaxial IN” (13) connections
serve as input.
Digital audio source with optical signal connection Digital audio source with coaxial signal connection
CONNECTION OF A RECORDING DEVICE
If you want, you can use the RCA sockets “OUTPUT REC” (12) 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 from the volume setting. Please note that while the preamplifier
is muted (10) 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.
CONNECTION OF ONE OR MORE POWER AMPLIFIERS
This preamplifier has two stereo preamplifier outputs with RCA connectors for
the main amplifier channels. In this way it is possible to drive four
loudspeakers or bi-amp one pair of loudspeakers (e. g. using two stereo main
amplifiers). The main amplifiers supply the system’s loudspeakers and the
loudspeakers are connected to the outputs of these. 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. Connect both sockets named “1” in the
field “OUTPUT” (15) with the RCA input sockets of the main amplifier channels
(often marked as “INPUT” or “POWER AMP IN”). Please pay attention not to
interchange right with left channels. The letters “R” and “L” indicate the
correct correlation. You may further use the SAT7MK preamplifier output marked
with “2” for a headphone amplifier.
You can as well use both stereo outputs at the same time, giving way for up to
4 main amplifier channels to supply their loudspeaker. For that all you need
to do is connect all remaining stereo outputs (15) with additional main
amplifier channel inputs.
CONNECTION OF ONE OR MORE POWER AMPLIFIERS The fact that this amplifier is equipped with two RCA stereo preamplifier outputs enables you to bi-wire your loudspeakers using adequate speakers and one or more additional main amplifiers. For the best rendering, amplifiers with transmission inputs (e.g. studio amplifiers) should be connected with the optimal output labeled „1“ in „Outputs“. Vincent amplifiers generally have input impedances > 10 kOhm and can be connected to outputs „1“ and/or „2“ anytime. Your HiFi specialist will advise you on this.
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 SA-T7MK is equipped with two output connectors for the power control.
Here, the switching signal generated by the SA-T7MK 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.
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”.
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 THE POWER CABLE
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.
Connect the other end of the mains cable to a mains socket.
SWITCHING THE VOLTAGE
This device is equipped with a switch (18) 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!
OPERATING THE APPLIANCE
Operation | Button(s) | Description |
---|---|---|
Switch on and off | POWER (2) | 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. As a precaution,
after switching on, the volume setting of the preamplifier should be reduced.
After switching on, the device needs up to 30 seconds before it is ready to
operate. Meanwhile, the LED in the speaker’s knob (9) will be blinking. During
power-on mode, one of the LED for the input selection will be lighted.
Select an input| INPUT (7)
Input keys (22)| At the front panel: If you turn the dial “INPUT”,
you select one of the devices connected to the inputs on the back of the SA-
T7MK (11)(13)(14) for playback. Using the remote control: A short touch on the
button for the desired input channel (e.g. “S1”) changes to the playback of
the audio source connected there. The LED associated to the selected input
channel will be illuminated at the front of the appliance. Before switching
over the input channel, the volume (9)(23) should be turned down as a
precaution!
Change the volume| VOLUME (9) VOLUME
▲/▼ (23)| At the front panel: Turn the knob “VOLUME” clockwise to
turn up the volume and counter-clockwise to turn it down. Using the remote
control: Press and hold the button “VOLUME” to raise its value. Use “VOLUME”
to lower the volume level. The volume setting does never influence the signal
at the output “OUTPUT REC” (12).
Mute the preamplifier output| MUTE (10)(21)| The MUTE (10)(21) function
can be activated on the unit (10) or with the remote control (21). It switches
off the preamplifier outputs (15) and the recording output (12). The LED in
the volume knob will be flashing during mute mode. Pressing the MUTE button
again restorest he volume to ist original setting.
Change the treble proportions of the sound| TREBLE (1)| With the
“TREBLE” control dial on the front of the device you affect the proportion of
higher frequencies in the sound. Turning it in clockwise direction increases
the treble intensity and moving it in anticlockwise di- rection reduces it. In
the middle setting the treble proportions of the input signals remain
unchanged. The adjustment of the treble control only has an effect if the
button “TONE” (4) has been pressed. The signal of the output “OUTPUT REC” (12)
is independent of this.
Change the bass proportions of the sound| BASS (3)| With the “BASS”
control dial on the front of the device you affect the pro- portion of lower
frequencies in the sound. Turning it in clockwise direc- tion increases the
bass intensity and moving it in anticlockwise direction reduces it. In the
middle setting the bass proportions of the input signals remain unchanged. The
adjustment of the bass control only has an effect if the button “TONE” (4) has
been pressed. The signal of the output “OUTPUT REC” (12) is independent of
this.
Switch off tone control (BASS/TREBLE)| Tone (4)| If the sound is not to be
changed, it is recommended that you switch off the sound control (BASS,
TREBLE) with this button on the front of the device. When this button is
pressed, the sound processing settings in the tone controllers (1)(3) come
into play. If the button is not pressed, the two sound controllers in the
preamplifier are bypassed and the signals from the source are not changed in
terms of their frequency levels.
Change the brightness of the tube window illumination| DIMMER (16)| The window
for the visible tube (5) could be illuminated with four bright- ness settings.
You can change the brightness by the switcher (16) on the backside of the
unit.
Switching between digital and analog input signal| ANALOG/ DIGITAL (8)| If you
have connected devices to the digital inputs (13) via optical or coaxial cable
or use the Bluetooth input (14), you can select these in- puts by pressing the
Analog/Digital (8) button. To do this, set the rotary control input (7) to the
appropriate input. If the button is not pressed, the appropriate analog inputs
(11) are active.
Playback of music by Bluetooth| Bluetooth Function| 1. Please select the
Bluetooth input (S4) on the SA-T7MK.
2. Please activate the Bluetooth connection on your smartphone, tablet or
computer.
3. Please select the search for new Bluetooth devices on your smart- phone,
tablet or computer. You will find the SA-T7MK under the name “Vincent” in your
list.
4. Please choose “Vincent” to connect.
5. The SA-T7MK is connected you can start the playback.
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 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 loud-
speakers, 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.
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 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 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.

input selector (INPUT).
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
preamplifier, 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.
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.
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 cylindricalshaped 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.
Output impedance
Term for the AC internal resistance of the driving signal source, here the
preamplifier. The output impedance of the signal source typically should be
significantly lower than that the input impedance of the power amplifier.
Exception: For power amplifiers with transmitter input an impedance matching
to 600 ohms is advantageous. Since between preamp and power amp the connection
should be done via coaxial shielded cables for the best possible reproduction
the output impedance should be designed so that the connected cables do not
have disturbing influence to the signal transmission. Typical cable impedances
are 50 – 75 ohm. The output 2 of the SA-T7MK is designed optimally for this
cable types.
