AUDIONET MACH ultra-reference preamplier

SCIENTIST SERIES – ULTIMATE MACHINE MACH

Following the design language of Hartmuth Esslinger, Audionet’s successful “Scientist Series” now has a new member, the ultra-reference preamplier “MACH”. Conceived as the little brother of the very popular STERN, the newly developed MACH combines all the design attributes and features of the Scientist Series with the proven genes of the “Audionet sound”.

The patented FLOATING PANE DESIGN encorporates the ultimate audiophile qualities.

Special features MACH

• Magnetically and capactively optimized circuit and device design without any ferro-magnetic materials.
• Floating Pane Design for optimal resistance against microphonic effects and temperature stability.
• The floating panels of the body are resonance-optimized by pads on an aluminum frame.
• Double mono layout of circuitry and power supply for maximum channel separation.
• The input and output sections as well as the volume control are implemented using enhanced, discrete Audionet operational amplifier modules (from the STERN) with state-of-the-art mica capacitors.
• Volume controller on a double ball-bearing axis and with magnetic ratchet and optical sensing.
• Volume controlled by electronic switches and real-time linearized precision resistor network.
• DC coupled with no sound diminishing capacitors or coils, shortest signal paths.
• Main power supply capacitors 22,000 µF, optimized for very low impedance and made with silk dielectric.
• Total capacitance of 176,000 µF.
• Microprocessor control with separate power supply monitor and control of all functions, informing the user on a high resolution display.
• By-Pass mode for integration into home cinema systems.
• Audionet Link outputs for the remote control of further Audionet devices.
• User definable names for each input, input levels adjustable for each input.
• User selectable function to remove DC levels from signal sources.
