Basic V2 Phono Stage

Dear Clearaudio customer,
Congratulations on the purchase of your new basic V2 phonostage.
Within that sleek aluminium casing (with silver or black anodized finish) lies an inner world of highly refined features. Its predecessor, the basic plus, was a multiaward winner and with the V2 we’ve taken all of that coveted ‘Plus’ technology up a notch.
On the outside, we’ve kept it very simple. There’s just one visible control, a single power switch on the upper surface that opens up a raft of possibilities.
On the underside you can switch between moving coil and moving magnet mode.
From there, you can easily enjoy the basic V2 with almost any high-end phono cartridge without making any further adjustments.
Or, you can choose from a range of performance enhancing settings to fine-tune its parameters to your system and your heart’s content. An optional subsonic filter attenuates any unwanted low frequency noise, while RIAA equalization accuracy is within 0.1dB.
All of which adds up to the basic V2 being the perfect all-rounder for both audiophiles and music lovers.
We wish you a lot of listening pleasure with your new Clearaudio basic V2 phonostage.
Clearaudio electronic GmbH

Safety instructions

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.
Intended use
The basic V2 is a phono preamplifier to amplify the signal of the phono cartridge.
The intended use of the basic V2 in accordance with the information provided in the user manual only.
The 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.
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).
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 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.
Overload
The product is designed to comply with all necessary safety regulations, however you should not leave the device unattended under extreme loads.
Maintenance
Only use a soft cloth with a smooth surface for cleaning. Never use agressive cleaning detergent.
Health information
Permanently high volume can lead to various types of hearing damage. Use high volume responsibly!

Setup

Select cartridge type operation mode:
Set the switches on the bottom panel of the basic V2 chassis as follows:

MM operation: Buttons ‘gain’ not pressed in (load impedance = 47 kOhm)
MC operation: Buttons ‘gain’ pressed in (load impedance = 500 Ohm)

Position MM = button not pressed, position MC = button pressed in.

Subsonic-Filter:
Set the switches on the bottom panel of the basic V2 chassis as follows:

Subsonic filter is on: Both buttons ‘subsonic’ pressed in
Subsonic filter is off: Both buttons ‘subsonic’ not pressed in

– Attention –
All switches are duplicated for the left and right channels.
Please make sure that both corresponding switches are always in the same position.
Before switching any settings be sure to shut off the power to the basic V2.
Never cover or put anything on top of the basic V2, which could lead to overheating of electronic parts.
If the unit is not in use for an extended period, switch it off.

Troubleshooting

If you have a problem with your basic 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!

Error	Cause	Measure
Device does not work	Is the power cord plugged in and the power switch
turned on?	Check the connection.
No sound or low volume?	Did you choose the right input?	Check the

connections of your hifi components.
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.
