DESCRIPTION & SPECIFICATIONS
The PA-1175 is one of the most innovative stereo
Power Amplifiers available on the market.
The PA-1175 is the Gold Note first stereo amplifier ever
made over 20 years of designing electronics.
As first ever made stereo amplifier the PA-1175
features a lot of innovations which have always
distinguished Gold Note's designs.
The PA-1175 merges the knowledge of the acclaimed
Demidoff single ended amplifiers with high power rate
never reached before.
The PA-1175 is a Dual-Mono amplifier featuring 4
matched pair of transistors per channel with a
proprietary Gold Note BIAS constant current generator
that 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. Being much more stable than the
traditional electronic ones the optical devices guarantee
extraordinary audio performance.
Besides, Gold Note introduced a new unique Optical
Protection for the output stage, featuring optical
decoupling that despite the traditional electronic ones
that typically downgrade the performance, analyze the
audio signal optically. The Optical Protection is
completely separated from the audio signal path
allowing a perfect protection of the unit and unbeatable
performance.
PA-1175 features a unique adjustable Damping Factor
design to set at DF of 250 or 25 allowing an ideal
match with any kind of speakers: delivering full power
and great control at 250 DF (necessary to drive large
and difficult speakers) or acting as a low power tube
amp at 25 DF (to drive high sensitivity or mini-monitor
speakers that don't require the energy of a big
amplifier).
The PA-1175 is a fully balanced amplifier featuring a
BTL design (Bridge-Tied-Load) which allows the unit to
be easily bridged working as mono amp doubling its
large power rate from 200watt per channel @ 8Ω to a
considerably 520watt per channel.
The existing flexibility of the stereo power amplifier could
be largely extended with the mono application for all
kind of speakers really requiring high power and great
energy.
The amplifier features a 640VA custom made toroidal
audio transformer dampened with original Ducati race
bikes silent blocks to guarantee e terrific effect and
perfect insulation.
A small 6VA transformer powers all service functions
outside of the audio signal path to obtain the best
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.
The PA-1175 is built around a very solid steel chassis
completed by large massive panels of aluminum to
avoid RFI and EMI.
Every Gold Note product is 100% proudly designed, manufactured and assembled in Italy
