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 requires 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
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 vapor 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 main 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.
OTHER INSTRUCTIONS
Setting up the appliance
How the system is set up has an effect on the sound quality. Therefore only
place it on a suitable, 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
2012/19/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 manufacturers to produce more durable or reusable products. For
further information about disposing of your old appliance, please consult your
local authority, waste disposal agency or the shop where you bought the
product.

To establish the power supply, connect the plugs of the power cable to the device and to a suitable wall outlet.
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 analog and digital outputs.
Make sure that you do not get these connections confused during installation!
Make sure that you do not mix up the analog connectors for right and left. The
RCA plugs for these are mostly color-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 a 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 stockist will be glad to advise you about this.
SWITCHING THE VOLTAGE
This device is equipped with a switch (8) 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 the
actuation of the switch! Information about the device fuse can be found on the
back of the device.
Unauthorized actuation of the switch will void any warranty claim!
CONNECTION OF THE SOURCE EQUIPMENT
Connection of a USB-source device
The D/A converter makes it possible to transfer digital music signals directly
from the computer through the amplifier similar to the boxes. For this, the
USB jack serves as input.
CONNECTION OF SOURCE DEVICES OVER OPTICAL IN AND COAXIAL IN
The 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.
Digital audio source with optical signal connection
Digital audio source with coaxial signal connection
CONNECTION TO AMPLIFIER, RECEIVER, OR PREAMPLIFIER
The DAC-1 MK has two analog signal outputs on the back of the device. The signal can be input to a traditional analog audio component (amplifier) via the analog outputs (6).
Use of one of the analog outputs with RCA connectors
This is where the stereo audio signal is converted to analog by the high-
quality D/A converter and amplified by the output stage. An RCA cable is
required for connection to an amplifier. Connect one pair of RCA connectors
(“L” and “R”) in the field “ANALOG OUTPUTS” (6 with the left and right audio
connectors of the amplifier input (standard line-level input) which is usually
labeled “CD,” “LINE IN” or “FRONT R/L”. If you want, you can use both outputs
at the same time.
Use of the analog output with XLR connectors
This is where the stereo audio signal is converted to analog by the high-
quality D/A converter and amplified by the output stage. Two XLR cables are
required for connection to an amplifier. Connect the XLR connector “L” and “R”
in the field “ANALOG OUTPUTS” (6) with the left and right connectors of the
XLR amplifier input which is usually labeled “CD,” “XLR IN,” “BALANCED IN” or
“FRONT R/L”.
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 a “POWER
CONTROL” circuit or “TRIGGER”. This kind of remote-controlled standby circuit
is used primarily for preamplifiers 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 DAC-1MK has an Input and an Output connection for the power control. It
could receive an input signal and could transfer the signal to another
unit.
CONNECTIONS FOR THE STANDBY CONTROL (POWER CONTROL)
Caution:
Many devices which can be controlled by a switching signal (not preamplifiers
or integrated ampli-fiers), 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 the socket
for the mains on the back of the device. Connect the other end of the mains
cable to a mains socket.

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, the ground potential of the chassis and the protective
ground wire are 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: 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 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 an “unbalanced signal connection”.
Dynamics
The volume difference between the quietest and the loudest sounds possible in
audio signals, without distortion or transition to noise.
