nano phono headphone V2
User manual
Dear Clearaudio customer,
congratulations on the purchase of your new nano phono V2 / nano phono
headphone V2 MC/MM phono stage.
The nano phono V2 / nano phono headphone V2 features a power switch: we
recommend that you keep the unit switched on in order to maintain a constant
temperature for the electronic parts inside (this uses very little power).
The new nano phono V2 / nano phono headphone V2 also has a built-in volume
control unit.
Please read this instruction manual carefully, to avoid any damage or loss of
warranty.
This manual will help you achieve an easy setup and guarantees the highest
pleasure for a long time.
We wish you a lot of listening pleasure with your new Clearaudio nano phono V2
/ nano phono headphone V2 phono stage.
Clearaudio electronic GmbH
Warning
Do not expose the equipment to rain or moisture.
Do not handle the mains lead with wet hands.
No naked flame sources, such as lighted candles, should be placed on the
equipment.
CE-MARKIERUNG
IMPORTANT!
First, select either the MC (moving coil) or MM (moving magnet) mode according to your cartridge type, by inserting the removable jumpers into the relevant positions on the bottom of the unit (one each for left and right channels). The subsonic filter function can also be adjusted by inserting jumpers into the relevant points on the bottom of the unit: if the jumper is inserted, then the subsonic filter is OFF. If the jumper is not inserted, then the subsonic filter is ON.
The next step is to connect the ground wire of the turntable/tonearm with the
nano phono V2 / nano phono headphone V2. Make sure that the gain control is
set to its lowest volume before connecting the nano phono V2 / nano phono
headphone V2 to your MC/MM cartridge and preamplifier.
Finally, the very last thing to do is to connect the power supply to the mains
and press the power button to the “ON” position.
– Attention –
Never cover or put anything on top of the Nano Phono V2 / nano phono headphone
V2 as this could lead to overheating of electronic parts.
If the unit a long time not in use, please press the button on top of the
device. If the device is not in use, disconnect it completely from the power
supply by removing the main plug from the socket.
– Notice –
If you are using the nano phono V2 / nano phono headphone V2 with a two-pin
mains plug, you may notice that inserting the plug into the mains socket one
way round gives a slightly better sound than the other way. Experiment to
identify which is the optimum position.
Phonostages provide a very high level of amplification, to address the fact
that the electrical signal generated by a phono cartridge is extremely low.
As a result, phonostages are extremely sensitive, which leads to the potential
problem that high-frequency interference may also be amplified to a point at
which it becomes noticeable. Unfortunately, it is not possible to completely
protect the sensitive phono stage circuitry from this interference without
degrading its high fidelity performance. Therefore care must be taken to
position the phono stage away from sources of high-frequency interference such
as mobile phones, modems, and powerline communication systems (PLC) in which
data is sent over the mains power network.
nano phono V2 product information
The nano phono V2 is a fully Dual Mono Design, designed for use with other MM
or MC cartridges. Cartridge type is selected with individual jumpers for the
left and right channels which are located on the underside of the unit.
The standard input impedance is set at 47 kΩ, which ensures an optimal setting
for all MM cartridges.
For the perfect input matching with MC cartridges, Clearaudio now includes the
following resistor pairs:
– 51
– 200
– 402 and
– 1000Ω
If there are no resistors connected to the jumpers while in MC mode, the
cartridge is automatically loaded with 47 kΩ.
The 402 Ω resistors are recommended for Clearaudio MC cartridges.
The other resistor values allow 3rd party MC cartridges to be loaded according
to the manufacturer’s guidelines. It should be noted that sometimes your
personal preference for cartridge loading may differ from that recommended by
the cartridge manufacturer.
If so, Clearaudio recommends: Trust your own listening abilities, in your own
surroundings!
Clearaudio wishes you a lot of pleasure listening to music!
