Marley MkII Rev.b

Headphones amplifier

The intimacy of Hi-Fi pleasure

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

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

The Marley MkII Rev.b 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 Rev.b to that of their headphones on their ear. Tone control can be deactivated.
Even old stereo recordings (affected by the so-called “ping pong effect” caused by excessive separation between channels) can be made more enjoyable by activating the cross-feed circuit.
Perfect match with any type of headphones is also achieved by selecting the output impedance between Lo-Z, 10 Ohm and 47 Ohm.
A recorder output and a pre output (which duplicates the unbalanced output on RCA connectors on the rear panel) allow you to use the Marley MkII Rev.b as a true preamp.

The Marley MkII Rev.b can be operated by front panel controls and IR remote control.
