Gold Note PA-1175 MKII Power Amplifier

Gold Note PA-1175 MKII Power Amplifier

The Gold Note PA-1175 MKII Power Amplifier is an exceptional choice for audiophiles who prioritize sound quality and versatility in their audio setups. With its Class AB design and proprietary Optical BIAS technology, this amplifier delivers high-power output with ultra-low distortion, ensuring that music is reproduced with the utmost clarity and fidelity. The ability to match a wide range of loudspeakers through its selectable damping factor further enhances its appeal, making it adaptable to both high-efficiency monitors and large, low-sensitivity speakers. This flexibility allows users to easily upgrade or change their speakers while optimising the amplifier's performance.

Additionally, the PA-1175 MKII’s BTL (Bridge-Tied-Load) technology allows for seamless conversion from stereo to mono, doubling the output power from 200W to an impressive 520W per channel. This capability ensures that even the most demanding loudspeakers can be driven effortlessly, providing the power and control needed for a dynamic listening experience. The amplifier's robust construction, featuring a steel chassis and thick aluminium panels, minimizes RFI and EMI interference, guaranteeing both durability and longevity. The specialized toroidal transformer also enhances sound quality by cancelling out mechanical vibrations and ensuring excellent isolation, contributing to the amplifier's efficient operation.

The Gold Note PA-1175 MKII is not only engineered for superior performance but also designed with user convenience in mind. Its front panel controls allow for easy selection of the damping factor, enabling users to tailor the amplifier’s performance to their specific listening preferences. This intuitive feature simplifies the setup process, making the amplifier accessible to all users, from seasoned audiophiles to newcomers. With its combination of cutting-edge technology, exceptional build quality, and user-friendly design, the PA-1175 MKII stands out as a worthy investment for anyone looking to elevate their audio experience.

Features

• Class AB Design & Optical BIAS: High power with ultra-low distortion for clear, detailed sound
• Selectable Damping Factor: Optimizes performance with various loudspeakers
• BTL Technology: Converts from stereo to mono, doubling power to 520W per channel
• Robust Build: Steel chassis and aluminium panels reduce interference and enhance durability
• Toroidal Transformer: Improves sound quality and operational efficiency

The power amplifier for the most demanding audiophiles

Class AB power amplifier perfectly matched to a wide variety of loudspeakers, thanks to the 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 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. 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, 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.
