Page 3: Safety Precautions
Safety precautions Children and minors are not to use the device and should be kept at a safe distance from the device while it is running. Do not run the device without the top cover in place. Voltages inside the amp can be lethal and temperatures are high. - Page 4 Connections At the rear side of the CORDA EARTUBE-1 two pairs of inputs allow you to connect two different audio sources that have typical output voltages above 0.1 Volts (CD-player, cassette-player, tuner, minidisc-player, ...). The source you want to listen to can be selected by the switch at the left front side of the amp.

Page 5: Volume Control
Volume control The volume of the CORDA EARTUBE-1 is controlled by the large dial on the left side of the front panel and is increased by clock-wise rotation. The driving capabilities of the CORDA EARTUBE-1 by far exceed that of a regular CD-player. This not only guarantees less distortion, but also has the danger of severe hearing damage. - Page 6 Directional listening In normal daily life people use various mechanisms to locate sources of sound. Firstly, the sound of a source to the right side of the listener (e.g. the right loudspeaker) not only reaches the right ear but, attenuated and delayed, is also heard by the left ear. The level of attenuation and the delay time of this crossfeed signal provide important directional information.
- Page 7 Fortunately, the main directional information is provided by the time delay and level of attenuation of the sounds that reaches the opposite ear. The CORDA EARTUBE-1 can electronically simulate this process and, with appropriate attenuation and delay, add some of the right audiosignal to the left channel and vice -versa.

Page 8: Replacing Tubes
Replacing tubes The EARTUBE-1 uses three tubes 6N3P and two tubes GU17 (or its equivalents QQE03/12, RS1023, 6360) If you want to exchange tubes, please disconnect the power cord before removal of the top cover. Also make sure that all pins are properly mounted into the sockets. It is not uncommon that a pin is bend and doesn't enter the socket. -
