SAFETY INSTRUCTIONS
1. Please read this operating manual carefully and observe all the instructions affixed to the appliance or written in this
manual.
2. Install this product on a stable surface and make sure that nobody can trip over the cables.
3. his product should only be connected to a power source indicated on the product. If you are unsure what power source
you have in your region, please contact your local power utility.
4. Never operate this product near water or with wet hands. If the product comes in contact with liquids, immediately
disconnect it from the power source.
5. o exclude the risk of an electric shock, please never expose the product to the rain or other source of liquid.
6. In thunderstorms, do not install the product or put it into operation.
7. Never attempt to open the appliance or repair it yourself. If you open or remove the enclosure, you may expose parts that
are subjected to dangerous levels of voltage. Any unauthorized opening of the appliance will cause the warranty claim to
become null and void.
8. Do not allow children to play with electrical appliances without adult supervision. Children do not always recognize the
possible risks and consequences.
SCOPE OF SUPPLY
he scope of supply comprises:
•RINI Y PHONO PREAMP
•RINI Y PHONO Load connectors (4pcs.)
•RINI Y PHONO one arm cable (optional)
•Dimension 400mm x 300mm x 96mm plus 15mm feet, weight 32kg
•1 x Flight Case, weight: 35kg, dimension: 65cm, 55cm, 30cm
TRANSPORTATION AND CLEANING
Please only transport the parts listed in the scope of supply in the supplied flight case and use the supplied cotton gloves
when unpacking and installing the appliances to avoid scratching the enclosures.
Clean the surfaces using the supplied microfiber cloth: immerse the cloth in lukewarm water containing no detergents and
then carefully wipe the surface when the cloth is almost dry.
Never use chemical or a ressive deter ents.
SELECTING THE POWER VOLTAGE
he implemented wide-range switched mode power supply modules allow an operation from 100Vac to 240Vac. he two
fuses on the primary side are placed inside of the power entry module and filter.
CONNECTING AND STARTING
o install the PHONO PREAMP, select a stable, level surface directly next to the turn table so that the connecting cable to the
tone arm is as short as possible. Avoid placing the appliance in direct sunlight and never place the modules directly next to
radiators or fan heaters.
Protect all supplied parts from humidity and moisture.
Only wire up the components when the device is switched off.
WIRING UP
1. Disconnect the PHONO PREAMP from the power source. Never disconnect any wires unless the device is switched off.
2. Connect the PHONO PREAMP to the tone arm.
3. Connect the PHONO PREAMP to the LINE PREAMP.
4. Connect the PHONO Load Connectors to the load connector XLR inputs.
5. he precision rotary switch can be operated by a coin.
6. Select the matching load for the used MC pick-up.
7. Additional connectors with any values can be ordered as an option.
THE LOW NOISE INPUT STAGE
Even a low noise amplifier contains different noise sources and all resistive sources create thermal noise depending on the
temperature.
As Mr. James Bryant from Analog Devices mentioned:
“So anywhere at all that there is resistance in a circuit, whether it is carrying current or not, there is a noise generator with
an output voltage noise spectral density of
4
kTBR
We can reduce the noise by reducing the resistance R (this may increase current and/or power consumption), but reducing
the temperature k is not usually practicable (if we cool a resistor from room temperature (298K) to liquid nitrogen
temperature (77K), its noise voltage is still more than half its room temperature value). And, of course, we can't chan e
Boltzmann's Constant because Professor Boltzmann is dead.”
he B stands for band width and will be discussed later.
When a source like a MC pickup with it matching resistor is connected to a phono preamplifier`s input the output noise
includes contributions from both the amplifier and the source resistance. here exists an optimum source resistance for any
given amplifier, which will provide the lowest noise factor, or in other words the highest signal-to-noise ratio for any specific
input signal.
Since the source resistance is determined by the pick-up manufacturer, there is only one way left to optimize the overall
noise performance of a phono preamplifier.
he amplifier has to be designed in that way that it matches with these source resistances of the MC pick-ups or at least
come close to this value.
After solving some partial differential equations, it can be shown that the optimum source resistance is
n
n
e
R
i
=
hat means for a given amplifier the optimum source resistance can be calculated. Beside the low noise performance, the
amplifier has to match to other requirements as well. For instance the amplifier has to be linear and should not add any
distortion or the bandwidth should be well above the audio bandwidth and so on.
