Lehmannaudio Traveler | Amplificatore per cuffie

An original product with great performance
--
Lehmann Traveler is the new portable headphone amplifier from Lehmann; battery powered, it allows extraordinary hifi quality in an extremely compact and elegant package.
Traveller, the result of decades of experience and passion for music by Norbert Lehmann who designed a sophisticated electronic circuit for this Traveller, using only first-class components, and without compromise.
The Traveler is very intuitive and simple to use, and has only 2 buttons; the volume control works electronically in a very precise way even at low listening levels, thanks to a resistive network controlled by a microprocessor. The last volume level set remains in memory even after the amplifier is switched off and contains a long-life battery capable of guaranteeing 20 hours of uninterrupted music at normal volume levels. In short, an intercontinental flight will not put the Traveler in crisis, obviously compatible with any portable music device, including smartphones and tablets.
The output stage with which it is equipped is discrete components and "zero feedback", with Lumberg 3.5mm jack connectors, both for headphone output and input for musical devices. The internal voltage gain circuit uses components from Analog Devices and Burr Brown. Traveler is completely analog, and is able to drive any headphone on the market in the correct way, as well as also functioning as a preamplifier for active loudspeakers, if used in a domestic environment thanks to two parallel inputs and two outputs, one on the front and one on the rear.
The Traveler was also designed for people with issues of imbalance or sound attenuation in one ear relative to the other. In these cases you can set the function called "Center Adjust", a sort of balance, which optimizes the sound image centrally. This function is also very useful in cases where the recording is unbalanced on one channel compared to the other.
