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 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 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”.
OTHER INSTRUCTIONS
Setting up the appliance
How the system is set up has an effect on the sound quality. Therefore only

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 separately

BUTTONS OF THE REMOTE CONTROL
17. MUTE
Pressing this button once mutes analoge output (8).
Pressing it again returns to the original volume.
18. Input selector buttons
Select the input source you want to listen to with these buttons.
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 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 (14) 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!
CONNECTION OF THE SOURCE EQUIPMENT’
Connection of a USB-source device
The integrated 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 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” (13) and “Coaxial IN” (12) connections serve as input.
Digital audio source with optical signal connection
Digital audio source with coaxial signal connection
CONNECTION OF SOURCE DEVICES OVER AES/EBU
The input “AES/EBU” (12) can only be connected with audio devices that own a balanced input connector, too. Leave the inputs 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 TO AMPLIFIER, RECEIVER OR PREAMPLIFIER
The DAC-700 has two analogue signal outputs on the back of the device. The signal from the integrated D/A converter can be input to a traditional analogue audio component (amplifier) via the analogue outputs (8).
Use of one of the analogue outputs with RCA connectors
This is where the stereo audio signal converted to analogue by the high
quality integrated D/A converter and amplified by the Hybrid stage is output.
One of the two outputs and an RCA cable is required for connection to an
amplifier. Connect one pair of RCA connectors (“L” and “R”) in the field
“ANALOG OUTPUTS” (8) with the left and right audio connectors of the amplifier
input (standard line level input) which is usually labelled “CD,” “LINE IN” or
“FRONT R/L”. If you want, you can use both outputs at the same time.
Use of the analogue output with XLR connectors
This is where the stereo audio signal converted to analogue by the high
quality integrated D/A converter and amplified by the hybrid stage is output
symmetrically. Two XLR cables are required for connection to an amplifier.
Connect the XLR connectors “L” and “R” in the field “ANALOG OUTPUTS” (8) with
the left and right connectors of the XLR amplifier input which is usually
labelled “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 “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 DAC-700 has an input and an output for power control. This means it can
receive the switching signal from a device and pass it on to another device.
The sending device (usually a preamplifier or integrated amplifier) can be
connected to each of the two “Power Control” connectors (10). If a
transmitting device is connected, the second jack connector is used to pass on
the switching signal or remains free.
Caution:
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.
OPERATING THE APPLIANCE
Operation | Button(s) | Description |
---|---|---|
Switch on and off | POWER (2) | The DAC is switched on and off using this |
button at the front panel. After switching on, the device needs up to 30
seconds before it is ready to operate.
Select input source| SELECT (3) (18)| With this button, you can select
between four input sources (AES/EBU, USB, Coaxial IN and Optical IN). By
pressing this button, the player changes to the playback of the device
connected thereto.
Switch between tube amplification and transistor amplification| TUBE/FET
(5)| This switch allows you to choose if the converted music signal that is
read from the CD is amplified to the output level using the internal TUBE
amplifier or the internal FET transistor amplifier. This selection can only be
made on the front panel.
Volume of the connected headphones (7)| LEVEL (7)| This function can
only be operated on the front of the device. Turn the dial “LEVEL” clockwise
to increase the volume in the headphones and anticlockwise- to reduce the
volume. This volume control has no effect on the output level of the analogue
“ANALOG OUTPUTS” (8) on the back of the device.
Mute the DAC| MUTE (17)| The MUTE function can be activated with the
remote control (17). It switches off the outputs (8).
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 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. 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.

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, FM
tuners, cassette players, DAT recorders, personal computers, re cord 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
preamplifier 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.
NOTES
Please keep the receipt, store it together with this manual. The receipt is your proof for the beginning of the warranty period. Note the serial number in the following box, you can read it from the rear side of the device.
