GOLD NOTE PA-1175 POWER AMPLIFIER
elegant and powerful
Here is Gold Note's first stereo amplifier, the very first in over 20 years in designing electronics, our latest creation that 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 a Stereo Power amplifier that features 4 matched pair of transistors per channel with a proprietary Gold Note BIAS constant current generator enables high current and high power rate with ultra low distortion.
The amplifier features a Gold Note innovative Optical BIAS that uses optical devices to control the voltage reference of the unit that being much more stable of the traditional electronic ones the optical devices guarantee extraordinary audio performance.
Featuring BTL technology [Bridge-Tied-Load] so the unit can be easily bridged to work as a mono amp doubling its large power rate from 175watt per channel @ 8ohm up to a considerably 350watt per channel.
The flexibility of the power amplifier can be largely extended with the mono application for all kind of speakers that really requires high power and massive energy.
With a 630VA custom made toroidal audio transformer having an unique cut spiral nucleus design completely cancelling mechanical vibrations enhanced by original Ducati race bikes silent block to guarantee e terrific effect and perfect insulation.
A small 6VA transformer powers all service functions out of the audio signal path to preserve the best performance.PA-1175 also powers a conveniently selectable front panel Damping Factor switch sets up 250 or 25 allowing an ideal match with any kind of speakers acting the amplifier full power and great control at 250 DF necessary with large and difficult speakers to drive while acting as a low power tube amps at 25 DF ideal to drive high sensitivity or mini monitor speakers do not agree the energy of big amplifiers.
We introduced a new unique Optical Protection for output stage featuring optical decoupling, to overcome downgrading performances solutions of traditional electronics, that optically analyzes the audio signal. The Optical Protection is completely separated from the audio signal path for perfect protection and unbeatable performance.
Top-level electronic components combined with outer connections RCA, XLR and original Rhodium Gold Note speaker terminals complete the PA-1175 high-level quality.
PA-1175 is built around a very solid steel chassis with thick aluminum panels to avoid RFI and Emi troubles at the same time.
