Clearaudio NANO PHONO HEADPHONE V2 - Handbuch (Seite 6)

2. Phonostages provide a very high level of amplification, to address the fact that the elec-
trical 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 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 fre-
quency interference such as mobile phones, modems and powerline communication sys-
tems (PLC) in which data is sent over the mains power network.
NANO Phono Product information
The Nano Phono is a fully Dual Mono Design, designed for use with either MM or MC cart-
ridges. 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
- 1000 Ω
If there are no resistors connected to the jumpers while in MC mode, the cartridge is auto-
matically 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 dif-
fer from that recommended by the cartridge manufacturer.
If so, Clearaudio recommends: Trust your own listening abilities, in your own surroundings!
