Safety instructions

1. General information

   • Check the device for visible damage before using it for the first time.
   • If the device is damaged, it should not be connected to the mains.
   • Also, never connect the device if it has been dropped or gotten wet, contact your dealer to have the device inspected.
   • Never expose the device to rain or moisture.
   • Never touch the power cord of the device with wet hands.
   • For your own safety, regular visual inspections of any defective insulation on the connection cable are also recommended. A damaged cable should be replaced immediately by a specialist!
   • Never pull on the power cable to unplug the device, but directly on the plug!
   • The inside of the device is maintenance-free, never open the housing or try to repair the device yourself. This can also lead to loss of warranty.
   • If you do not operate the device for a longer period of time, we recommend disconnecting the power supply from the mains.
   • Not suitable for children! Scope of delivery may contain small parts that can be swallowed.

2. Intended use

   • The nano phono V2 is a phono preamplifier to amplify the signal of the phono cartridge.
   • The intended use of the nano phono V2 in accordance with the information provided in the user manual only.
   • UThe power supply may only be operated with maximum permissible connection values according to the technical data. Any other use or modification of this product is not intended.

3. Location of installation

   • The device should only be set up on leveled surfaces.
   • Avoid location with direct sunlight, temperature fluctuations and high humidity. Likewise, avoid placing electronic devices near heaters, heat lamps, or other devices that produce heat.
   • The device is designed for operation in heated rooms.
   • Never block the ventilation slots or cover the device with a cloth or similar.
   • No objects with an open flame may be placed on the device (burning candles or similar).
   • Phonostage 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, phono stages 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 frequency interferences such as mobile phones, modems and powerline communication systems (PLC) in which data is sent over the mains power network.

4. Overload
   The product is designed to comply with all necessary safety regulations, however you should not leave the device unattended under extreme loads.

5. Maintenance
   Only use a soft cloth with a smooth surface for cleaning. Never use aggressive cleaning detergent.

6. Health information
   Permanently high volume can lead to various types of hearing damage. Use high volume responsibly!

7. Service

   • During the gurantee period, the nano phono V2 may only be repaired by the manufacturer, otherwise the warranty will become void.
   • All Clearaudio products should only be serviced by specialist retailer.
   • If despite the high production standard, a repair is necessary, the nano phono V2 must be sent to Clearaudio through your dealer.

Setup

1. The nano phono V2 is a fully Dual Mono Design, designed for use with either 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.
   • 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 standard input impedance is set at 47kΩ, which ensures an optimal setting for all MM cartridges.
   • For the perfect input matching with MC cartridges, Clearaudio includes the following resistor pairs:
   • Pic. 2: Colour codes ofthe resistors
   • If there are no resistors connected to the jumpers while in MC mode, the cartridge is automatically loaded with 47kΩ.
   • The 402Ω 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!
2. The subsonic-filter function can also be adjusted by inserting jumpers into the relevant points on the bottom of the unit.\
3.  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.
4.  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 longer 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.
   • Clearaudio wish you a lot of pleasure listening to music!

Troubleshooting

• If you have a problem with your nano phono V2, first check the possible causes to rule out incorrect operation.
• If the error persists, please contact your dealer!
• Never try to open the device and/or repair it yourself, this will void the warranty!

Have you selected the correct operating mode?| Check the settings on the underside of the phono stage.
Is the device in „mute“ mode or is the volume set too low?| Check the volume setting of your device.
The connection cables are not properly connected.| Check the tonearm and cartridge connections due the their respective user manual.
Devices with a headphone output only: Are the headphones still plugged in when you are trying to play music through the speakers?| Disconnect the headphones.
Hum or noise| The ground cable is not connected or is faulty.| Connect the grounding cable from the turntable/tonearm to the respective grounding connection on the back of the device. If there are several ground connections, interrupt them one after the other and check the sound quality again.
The device should not be operated in the vicinity of high-frequency devices such as mobile phones or modems or on power supply systems used for data traffic (PLC).| Make sure there is a minimum distance of 30cm between the power supply units of any type and the MC preamplifier or phono preamplifier. Powerlan adapters should not be operated on the same socket as the phono preamplifier.
One channel quieter or louder| The channels of an input are set differently.| Check the settings on the underside of the phono stage. These must be carried out identically for an input.
