16.10.2015

 New stereo power amplifier PA-1175 from the company Gold Note Built in the concept of dual mono. Every news channel has 4 pairs of transistors consistent with the company’s technology, management bias current ( BIAS ), which provides high output current and high output power with ultra-low distortion.
 

 The amplifier is equipped with an innovative system of adjustment of the bias current ( OPTICAL BIAS ), which uses optical devices for controlling the reference voltage, and is much more stable than conventional electronic systems. In addition to the Gold Note PA-1175 optical system used to protect the output stages, which in contrast to the traditional protection systems completely separated from the signal and does not reduce the sound quality.
 

 One of the most interesting features of PA-1175 – the button DF on the front panel, which allows you to select the dumping factor of the amplifier 25 or 250 . The choice depends on the sensitivity of the speakers, as well as the amount of bass that you wish to receive.
 

 Gold Note PA-1175 fully balanced amplifier. The power amplifier in dual-channel mode is 175 Watts into 8 ohms , in the bridge connecting the – 350 Watts into 8 ohms .
 

 The amplifier is equipped with special toroidal transformer power 800 VA . To maximize the quality of the transformer installed in the original dampening unit, which is used by Ducati at its best racing motorcycles. Small power transformer 6 VA is used for service functions.
 

 The Gold Note PA-1175 uses electronic components of top-level speakers and proprietary terminals with rhodium. The amplifier is mounted on a rigid chassis made of steel bars, the outer part of the body – thick aluminum panels, reducing the influence of magnetic fields and radio. The design of the amplifier designed by architect Stefano Bonifacio ( Stefano Bonifazi ).
 

 The suggested retail price of new items is 6000 euros.
