Marley MkII

Headphones amplifier

The intimacy of Hi-Fi pleasure

The Marley MkII is a high-performance headphones amplifier packed with everything you need
for first-class headphone listening.

Its low-noise discrete component design with FET input delivers crystal-clear power to any headphones.
The total absence of background noise, even with the most sensitive headphones, is guaranteed by a very low noise dual regulator.
Up to 10Vrms of max output voltage (20Vrms at the balanced output) allow each model of headphones to express themselves at their best.

The Marley MkII is very versatile: apart from the availability of unbalanced and balanced inputs, it features a three-band tone control
to allow the user to match the frequency response of the Marley MkII to that of his headphones on his or her ear. Tone control can be turned off.
Even old stereo recordings (affected by the so-called “ping pong effect” caused by excessive channel separation) can be made more enjoyable by activating the cross-feed circuit.
Perfect match with each type of headphone is also achieved by selecting the output impedance between Lo-Z, 10 Ohm and 47 Ohm.
A recorder output and a pre-out (duplicating the unbalanced output on RCA connectors on the rear panel) allow you to use the Marley MkII as a true preamplifier.

The Marley MkII can be operated by front panel controls, IR remote control and an app (available for both iOS and Android) via the Bluetooth Low Energy interface listed is equipped.
