Description

The power amplifier for the most demanding audiophiles

Class AB power amplifier perfectly matched to a wide variety of loudspeakers, through its selectable damping factor. The proprietary optical BIAS offers high power combined with very low distortion - it controls the reference voltage with great precision and stability compared to traditional systems. The optical signal analysis takes place separately from the audio path, ensuring loudspeaker protection and unbeatable performance. The Gold Note PA-1175 MkII is designed to minimise all kinds of 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. With 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, cancelling out any mechanical vibrations and guaranteeing exceptional performance and perfect isolation. A small secondary transformer takes care of 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 all types of loudspeakers to be driven.

Setting the damping factor to 250DF allows the full potential of large, low-sensitivity loudspeakers to be exploited, while the value at 25DF is a perfect match for high-efficiency loudspeakers or small monitors that do not like the high current output of large amplifiers.
