        200 watts into 8 ohm per channel power amplifier fully balanced selectable RCA or XLR output, can be be used as a mono amplifier for 520 watt / channel – with adjustable damping factor to match almost any speaker.

        Product description

        Here is Gold Note's first stereo amplifier, our latest creation features all the innovations that have always distinguished our designs: PA-1175 merges the knowledge of the acclaimed Demidoff single ended amplifiers with high power rate never reached before as well as new innovative technologies.

        PA-1175 is our first stereo Power Amplifier: a new design that features 4 matched pair of transistors per channel with a proprietary Gold Note Optical BIAS and a constant current generator to achieve high-current and high-power rates with ultra low distortion.

        Our proprietary and innovative Optical BIAS control the voltage reference of the unit: it features optical decoupling to overcome the inefficient and downgrading solutions of traditional electronics, optically analyzing the audio signal while being completely separated from the audio signal path for the highest protection and unbeatable performance.

        The BTL technology [Bridge-Tied-Load] allow the unit to be easily bridged in order to work as a mono amplifier, more than doubling its already great power rate from 200 watts  per channel @ 8ohm up to 520 watts per channel.

        The flexibility of PA-1175 and its performance can be pushed even further when used as a mono unit with speakers that really requires high power, massive energy and quality watts.

        For PA-1175 we developed a custom 640VA toroidal transformer with a unique cut spiral nucleus: the refined mechanical process makes the nucleus completely stable, cancelling any mechanical vibration to guarantee a terrific effect and perfect insulation, further enhanced by the use silent blocks.

        A secondary small 6VA transformer powers the auxiliary functions with dedicated circuits outside of the audio signal path.

        PA-1175 is a unique power amplifier: it features an adjustable damping factor technology that you can easily select straight from the frontal panel.
        Changing the Damping Factor to 250 or 25 will let you find the ideal match between PA-1175 and your speakers: use a 250DF to get the power and control necessary to drive large, difficult speakers or set it on 25DF to use it as a low power tube amplifier, perfect to drive high sensitivity speakers and smaller speakers.

        To avoid any RFI and Emi potential issue, we have built PA-1175 starting with a massive solid steel chassis and adding thick aluminum panels.
