Manley Labs Absolute Headphone Amplifier in Black
Manley Labs is proud to announce the release of a stunning design: the Absolute Headphone Amplifier. Brimming with functionality, this new art piece from Manley Labs is as enthralling musically as it is handsome visually.
With over three years of development in its creation, Manley has drawn from its 30 years of experience in conceptualizing and developing each precise element of this multi-talented unit. This masterpiece embodies high-performance flexibility for every person to be able to custom compose sonic performance reliably, repeatedly, or even spontaneously. Artistic expression with sound!
Oh, and by the way, it is also a Line-Level Preamplifier!
DETAILS
There are fifteen independent controls available, each of which was exhaustively developed for convenient adjustability and aural variety. Two selectable stereo RCA jack pairs receive the input signals. Even these RCA jacks are of our own design. Teflon® insulated and gold plated, we have been producing these excellent RCA jacks since the mid-1990s. The volume is controlled on the facia by the sexy front thumb wheel and also by the included Radio Frequency remote control, both of which operate a precision stepped relay ladder matrix attenuator in half dB steps. The RF remote can be operated anywhere in the home, even through walls or cabinetry, especially useful when using the unit as a stand-alone preamplifier. Next to the front volume control wheel you’ll find the Mute switch to instantly kill the signal. Spinning the volume wheel all the way to minimum also mutes the signal. There is also a user adjustable Headphone Overload Protection System which declares maximum output level to protect precious headphones and your ears!
And you know how maddening it is to try to listen to a mono LP record on headphones – which is why we have provided a MONO switch!
