Clearaudio NANO PHONO HEADPHONE - Handbuch (Seite 3)

E
The RIAA-MC/MM-preamplifier Nano Phono and Nano Phono H” has
been developed for highest demands in analogue music reproduction.
The Nano Phono / Nano Phono “H” has no power-switch and should be
always connected with mains in order to keep the ideal temperature for the
electronic parts inside.
- Set up –
(for Nano Phono / Nano Phono “H”)
IMPORTANT!
First, choose the operating mode (MM or MC) on the bottom of the
Nano Phono / Nano Phono “H” via jumpers (left and right channel
separately). Also the subsonic-filter function can be adjusted by setting
Jumpers on the bottom of the unit
- If the bridge is inserted, than subsonic filter is OFF
- if the bridge is out, than subsonic filter is ON
After that connect the ground of the turntable/tonearm with the Nano
Phono / Nano Phono “H”. Make sure, that the gain control is adjusted at
its lowest volume. Now you can proceed with connecting the Nano Phono
/ Nano Phono “H” to your MC/MM-cartridge and preamplifier.
The very last thing to do, is to connect the power supply to the mains.
- Attention -
Never cover or put anything on top of the Nano Phono /
Nano Phono “H”, which could lead to overheating of electronic parts.
- Notice -
Be aware of the right polarity of the external power supply by changing the
phase of the mains plug. If no phase testing equipment is available, try to
find the right position of the power supply by alternately turning the plug and
listening. You will hear the difference!
Phonostages are devices designed to provide a very high level of
amplification. This is necessary because the electrical signal generated by a
phono cartridge is extremely low (usually less than one-thousandth of a
volt). The job of the phonostage is therefore to accurately equalise the
phono signal and boost it to line level (measured in volts).
However, phonostages are by nature 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
phonostage circuitry from this interference without degrading its high fidelity
performance. Therefore care must be taken to position the phonostage 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.
