Gold Note PA-1175 Mk2

The Gold Note PA-1175 Mk2 power amplifier perfectly matched to a wide variety of loudspeakers, thanks to the selectable damping factor. The proprietary optical BIAS offers high power with very low distortion: it controls the reference voltage with greater precision and stability than traditional systems. The optical signal analysis takes place separately from the audio path, ensuring loudspeaker protection and unbeatable performance. The PA-1175 MkII is designed to minimise RFI and EMI interference, taking advantage of the thick aluminium panels featuring the typical Gold Note design.
BTL [Bridge-Tied-Load] technology allows the stereo amplifier to be bridged, transforming it into a mono power amp and increasing its power output from 200W@8Ω per channel to the considerable 520W@8Ω per channel. Thanks to this feature, the most demanding loudspeakers on the market can be easily driven.

The PA-1175 MkII power transformer is a special toroidal design featuring a spiral core. The refined mechanical process makes the core completely stable, eliminating mechanical vibrations and guaranteeing exceptional performance and perfect isolation. A small secondary transformer handles all auxiliary functions to preserve the audio signal.
The PA-1175 MkII also features a proprietary technology that allows the damping factor to be selected directly from the front panel, enabling the drive of all types of loudspeakers.
Setting the damping factor to 250DF allows the full potential of large, low-sensitivity loudspeakers to be exploited, while 25DF is a perfect match for high-efficiency loudspeakers or small monitors that do not like the high-current output of large amplifiers.
