PA-1175 Mk II Power Amplifier

THE CONTEMPORARY POWER AMPLIFIER

The PA-1175 MkII is the second generation of Gold Note High-End stereo Class-A/B Power Amplifier. Its new solid state design features a proprietary Gold Note Optical BIAS proprietary creation that enables a constant current generator to achieve high current and high power with ultra low distortion.

Gold Note's proprietary and innovative Optical BIAS design controls the voltage of the unit. It features optical decoupling to overcome the downgrading solutions of traditional electronics. Analysing optically the signal while it gets completely separated from the audio signal path assures highest protection and unbeatable performance.

To avoid RFI and EMI interferences, the PA-1175 MkII is made of a massive steel chassis and thick aluminium panels vented by the unmistakable Gold Note curved slots design.

The BTL technology [Bridge-Tied-Load] allows the unit to be easily bridged in order to work as a mono amplifier. The remarkable 200W @ 8Ω per channel in stereo mode grow up to a considerable 520W per channel in mono. Pushing further the pure audio performance, it allows the PA-1175 MkII to drive easily the most demanding power speakers on the market.

The PA-1175 MkII power transformer is a special toroidal model featuring a unique cut spiral nucleus. The refined mechanical process makes the nucleus completely stable, canceling any mechanical vibration to guarantee a terrific performance and perfect insulation, while a small secondary transformer powers the auxiliary functions with dedicated circuits outside of the audio path signal.

The PA-1175 MkII is an outstanding power amplifier featuring a proprietary adjustable Damping Factor technology that can be easily selected from the front panel. Setting the Damping Factor to 250 or 25 will let you find the ideal match with any kind of speaker. Use it at 250 to get the power and control necessary to drive large, low- sensitivity speakers or set it at 25 to use the amplifier as if it was a low-power tube amplifier, perfect to drive high-sensitivity and mini monitor speakers.
