PA-1175 is our first stereo Power Amplifier: a new design that features 4 matched pairs 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 analysing 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 175W per channel @ 8ohm up to 350W 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 630VA 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 of original Ducati 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 aluminium panels.
