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. 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. Unleashing the Power of Pure Sound Imagine an amplifier that not only elevates your home theater experience but transforms it into an auditory journey that rivals a live concert. The Gold Note PA-1175 MK II Power Amplifier is the maestro of this journey, orchestrating every note with precision and power, ensuring that your music and movies resonate with an intensity that is both felt and heard. The Essence of Italian Craftsmanship From the heart of Italy, a country renowned for its rich history in art and design, comes the Gold Note PA-1175 MK II. A true testament to Italian craftsmanship, this stereo Class-A/B power amplifier is a masterpiece that blends aesthetic beauty with technical prowess. Its massive steel chassis and thick aluminum panels are not just for show; they promise durability and a vented design that allows for optimal thermal efficiency. Superior Audio Fidelity - Power Output Delivering 200W per channel at 8 ohms in stereo mode and a staggering 520W per channel in mono, the PA-1175 MK II ensures that it can drive even the most power-hungry speakers with ease. Custom Transformer At the heart of this beast lies a special toroidal transformer with a unique cut spiral nucleus designed for superior energy efficiency and minimal electrical noise. Optical BIAS The proprietary Gold Note Optical BIAS control system provides smooth and detailed sound, ensuring that the amplifier operates in pure Class-A for the most natural and musical performance. Tailor Your Sound The PA-1175 MK II boasts a user-adjustable damping factor with settings of 250 or 25. This innovative feature allows you to alter the output impedance, giving you significant control over the listening experience. It's akin to switching between a high-power solid-state amp and a more intimate tube amp, all within the same unit. Design That Speaks Volumes With dimensions of 430mm W x 135mm H x 370mm D and a weight of 20.5 kg, the PA-1175 MK II's compact and stylish design is sure to complement any home theater setup. Choose from elegant finish options such as black, silver, or gold, and personalize it further with stripe accents in walnut, acrylic, or aluminum. Unwavering Performance Bridge-Tied-Load (BTL) Easily bridgeable to mono, the PA-1175 MK II offers flexibility and power in a single package. Dedicated Circuits A secondary transformer takes care of auxiliary functions, ensuring that the audio signal path remains pure and uncolored. Mechanical Silence The use of viscoelastic isolators with the transformer guarantees that mechanical noise is a thing of the past, allowing nothing but the music to move you. Sound That Resonates The fully balanced high-power design of the PA-1175 MK II ensures that the audio performance is nothing short of phenomenal. With a frequency response of 1Hz – 100KHz @ ± 1dB, every note is played back with the fidelity it deserves. The signal to noise ratio of 110dB means that the music stands out against a backdrop of pure silence, and the total harmonic distortion (THD) of less than 0.01% ensures that what you hear is as close to the original recording as possible.
