Meier Audio Corda 3Move

  • From the energy of two small batteries a portable CD- or MP3-player nowadays feeds us with many hours of music. However, the use of a supply voltage of just 1,5V or 3V has its price. Many headphones require quite a high signal to obtain reasonable sound levels. The low supply voltage simply doesn't provide enough "juice" to drive these headphones properly and sound quality is impaired.

    The CORDA 3MOVE is a portable headphone amplifier meant to "replace" the standard headphone socket of your player. It has an internal supply voltage of 9 or 18V (low/high current consumption mode) and thus much better driving capacities. Connecting this amp to you portable will simply make your headphone sound better. Of course the 3MOVE also has a built-in crossfeed filter which makes headphone listening more natural and relaxing.

    The amplifier also has a built-in digital-to-analog converter (DAC) and can be directly connected to an USB-port of your computer. The quality of this DAC clearly surpasses that of the soundcards found on most computers.

    All important control elements and sockets are found on the front of the amp so it can be used while being carried in a pocket or a bag. The volume control is relatively small and will not rotate easily while accidently being touched by clothes or arm.

    The metal enclosure of the 3MOVE is very sturdy and the amp has been build to last for years and years.

    The circuitry inside needs very little current and the amplifier runs for upto approximately 100 hrs on a single 9V battery (low current consumption mode). To prevent unintended current drain the amp has a LED-powerindicator.

    To save batteries and to increase sound quality at home an external powersupply can be connected with a supply voltage up to 12V DC.
