S3 Pro-Ject Vinyl NRS Box Debut PRO S Turntable
Dear music lover,
thank you for purchasing this Pro-Ject Audio Systems´ product.
In order to achieve maximum performance and reliability you should study these
instructions for use carefully.
Warning of a hazard for the user, the unit or possible misuse.
Important notice.
Safety instructions
AC outlet voltages vary from country to country. Before connecting to the
mains, make sure that the voltage in your area meets the voltage requirements
printed on the power supply.
The power supply is used to connect/disconnect the unit from the mains. Make
sure that the power supply is easily accessible at all times. Never handle the
device, the power supply while your hands are wet or damp. Avoid letting
liquids enter the device or the power supply. Never place any item containing
liquid, such as a flower vase on or near the device. Never spill any liquid on
the device or the power supply. Never place any naked flame sources, such as
lighted candles on or near the device. The product shall not be used in damp
or wet locations, next to a bathtub, sink, swimming pool or any other similar
conditions.
Connectors
Make all connections whilst the
device is disconnected from the power supply.
Take care to connect the left and right channels correctly. The right channel
is usually marked red, the left channel black or white. Never use any other
power supply than the one supplied with the unit!
Line In
Connect the output of the phono preamplifier to the RCA Line In.
Line Out
Connect the Line Out of your Vinyl NRS Box S3 to a line input of your
preamplifier or integrated amplifier.
Mains power connection
Connect the low voltage plug from the power supply to the Power 18V DC socket
of the amplifier before connecting the power supply to the mains.
Front panel controls
To switch on from standby or to standby
The push button on the left side of the front panel turns the unit on or back
into standby/bypass mode. The blue LED beside the stand-by push button shows
that the unit is switched on. It takes approximately 3 seconds to activate the
electronics until it goes into operational mode. If the unit is switched off,
line in and line out sockets are linked together and all the electronics are
disconnected from the signal path – pure bypass mode (galvanic bypass).
VNRS
VNRS stands for “Vinyl Noise Reduction System”. If the button is pressed, the
system is activated and noise from the played record is reduced. VNRS can
reduce vinyl surface noise and turntable drive noise up to 6dB, while played
music stays practically untouched. The LED shows the on/off status of the
VNRS.
De-Crackle
The De-Crackle function allows you to reduce crackling sounds coming from the
record. You can adjust the sensitivity of the algorithm by turning the
potentiometer. Normal working position is in the center. If you turn it fully
counter-clockwise (left), the algorithm is switched off. (This position is
usable if you are playing a perfectly intact record and only want to use
VNRS.)
If you are playing a slightly used or slightly damaged record, you must find
the optimal position in which the music stays untouched, but the crackling is
reduced. Start in the center position. Detected crackle and clicks are
indicated by the red LED located right beside the De-Crackle control. If the
LED blinks, crackling was detected and reduced. Find the position in which
crackling is reduced sufficiently, but the music stays subjectively untouched
(with no audible distortion). This position is usually +/-30 degrees left or
right from the center position.
The optimal position depends on the status of the used record, type of
cartridge and type of phono preamplifier. Optimal position can slightly vary
from track to track on the record. In low level parts of the music and between
tracks, the De-Crackling system is more sensitive. In this situation, the
crackle detection LED blinks more often.
If you want to compare the sound with and without this device, simply switch
it OFF. The galvanic bypass takes place, and you can directly compare it to
the dry signal. After switching ON, it is necessary to wait about 3 seconds
until the operation mode is active.
Intensity
The De-Crackle algorithm can be used in two intensity levels for reducing of
detected crackling. If the Intensity button is not pressed, the basic
intensity level is used. If the Intensity button is pressed, the advanced
level (stronger) is used. The advanced level is more effective, but could
affect the music. For most new or slightly used records, the basic level
should be fine. For used records, switch to advanced level. Try to fine tune
DeCrackle control individually. Listen in both positions and choose
subjectively better one for each record. If advanced intensity level is
activated, indication LED lit.
-6dB
If the input level is too high, clipping can occur. In this case, the red clip
LED located right beside the -6dB switch blinks and indicates a system
overload. In such a situation, please reduce the gain of your phono
preamplifier. If your preamplifier does not have a gain setting, press the
-6dB button on your Vinyl NRS Box S3. Clipping should no longer occur.
Note that this reduction does not affect the bypass mode! Bypass mode
will be 6 dB louder than operational (ON) mode in this case.
