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:
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
Take note of the instructions for using batteries in
the chapter "Remote Control".
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 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 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 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 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 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
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 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.
ON
OFF
Do not open the appliance! Risk of electric shock!
There are no parts in the appliance that require maintenance by the user.

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.
Old electronic equipment
This appliance is subject to the conditions set out
in the European Directive 2002/96/EC. This is
identified by the symbol of a crossed out waste bin
on the appliance.
What this means for you as a consumer:
All old electrical and electronic equipment that is
no longer used must be disposed of separately
from domestic waste using places provided by the
authorities. By doing so you can prevent damage
to the environment and help to encourage manu-
facturers to produce more durable or reusable pro-
ducts. For further information about disposing
your old appliance, please consult your local aut-
hority, waste disposal agency or the shop where
you bought the product.
CE sign
This appliance complies with the current EU direc-
tives about attaining the CE mark and thus meets
the requirements for electrical and electronic
equipment (EMC regulations, safety regulations
and regulations for low voltage equipment).

INCLUDED IN DELIVERY
DESCRIPTION OF THE APPLIANCE
Please check the contents of the packaging, which in addition to the
appliance should contain the following accessories:
• 1 power cable
• 1 stereo set of RCA cables to connect the main amplifier
• 1 remote control “AM/FM STEREO TUNER”
• 2 battery cells size AAA (LR3)
• 1 loop antenna
• 1 FM (VHF) wire antenna
• this manual
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. Very few
options are available for those, who wish to com-
bine top-of-the-line amplifiers with an equally good
FM tuner.
The STU-2 is an AM/FM tuner with remote control
function from the Vincent product range. The built-
in preamplifier circuitry is based on the vacuum
tube 6N16, creating an enjoyable sound full of
suspense. This circuitry is a variant of the transi-
stor-tube hybrid technology Vincent brought to per-
fection, combining the advantages of amplifiers
using transistors and amplifiers using tubes. The
outcome of extensive developmental work and
component selection is a tuner that brings out the
maximum from the FM transmitter signals. The
audio reproduction of a dwindling numbers of
radio stations, who transmit high-quality music wit-
hout excessive signal compression, will become a
pleasurable experience that extends to the visible
appearance of this device by the presence of a
tube display window. Other features of the tuner
are its remote controllability, RDS functions, 30
station memories as well as a display screen that
can be dimmed and switched off. Highest quality
workmanship and an excellent prize-performance
ratio are the most obvious features.
This tuner is a perfect partner for amplifiers as well
as DVD players, CD players, tuners, headphone
amplifiers and loudspeakers from the Vincent
range. In combination with the HiFi furniture and
speaker cables from the range, one can build a
perfectly harmonious system.

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 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 cau-
sed by antenna-connected components (as TV-sets
or Tuners), personal computers, electrostatic loud-
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 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 cen-
tral grounding point is attached to. By doing this
the housing is able to shield all signals from exter-
nal radiated noise. Some main amplifiers are
equipped with a "Ground Lift" 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.

Symptom Possible Cause Countermeasure
Unit does not work
after pressing the
power button
Mains cable is not connected to a suitable
mains wall outlet.
Mains cable has not been firmly inserted into
wall power socket and the device’s socket.
Otherwise it may be defective.
Unit fuse or unit is defective.
Connect to a functioning socket using a suit-
able mains voltage.
Check the power cable. If necessary,
exchange it with a suitable mains cable and
push its plug firmly into wall socket and the
device's power connector.
Contact your dealer.
No sound on both
channels although
the unit is ready for
use (LED “WARM UP“
is lit)
The output of the tuner is not connected or is
not connected correctly to the selected input
channel terminal of the amplifier.
No frequency with a strong enough signal is
tuned.
No appropriate antenna corresponding to the
frequency band (AM/FM) is attached to the
tuner.
A wrong input channel has been selected at
the amplifier.
Volume level has been set too low.
The amplifier is muted (MUTE-Function).
Correct the connection.
Set a station frequency with a strong signal. In
case of AM reception, try to position the anten-
na in a better way.
Attach an appropriate antenna (13)(14).
Set the amplifier to the input that your desired
source is connected to.
Carefully increase the output level.
Deactivate the MUTE function after, as a pre-
caution, reducing the volume level.
No audio playback
on one channel
One of the signal cables between tuner out-
put and (pre-)amplifier input has not yet been
plugged in or is defective.
Check the cable connections, tighten them if
necessary.
Weak reception
or no reception
Antenna not or not properly connected.
The antenna for medium wave (AM) is not
positioned correctly.
Source of disturbance is near.
The operating mode (AM, FM) is in the
wrong setting.
The signal of FM station is too weak (transmit-
ter is possibly at a great distance).
Check the connection of the antenna (13)(14)
belonging to the selected operating mode
(AM, FM).
Try various possibilities for placing and posi-
tioning the antenna.
Try to locate and eliminate the disturbance.
Change the operating mode (AM, FM) with
the button “AM/FM” (9)(22).
Try to improve the reception by pressing the
button “ST/MONO” (8)(26) or search for
another station.
