DESCRIPTION AND SPECIFICATIONS
PSU-
1250
has been engineered with the best quality
audio-grade components to enhance the performance of
the Gold Note 1000 series of electronics, such as: CD-
1000, DS-1000, PH-1000 and P-1000.
For the PSU-
1250
we engineered a sophisticated 1250W
design powered by a double inductor driving the negative
and positive high current stages and featuring and
inductive filter on the analogue stage.
The PSU-
1250
can deliver high quality power using 7
transformers: 4 are dedicated exclusively to the power
supply, other 2 are dedicated to the inductive filter and the
chokes and 1 for the galvanic insulation of the audio stage.
The PSU-1250 is a super inductive & chokes power supply dedicated to the Gold Note 1000 series of electronics.
MAIN FEATURES
Seven rail audio grade power supply
Seven low noise voltage regulator
+12V, +8V, +5V for logic
+/- 12V for analog with inductive noise remover
+/- 28V for analog with inductive noise remover
Line & Load regulation for all outputs 0,05 %/V
Line noise rejection >80dB
Common mode noise rejection >80dB
Full power response time <2,5uSec
Absolute phase control from front panel
The Gold Note proprietary Dual Chokes Design perfectly
filters the signal voltage in order to eliminate electrical
pollution coming from the electrical power grid.
The PSU-
1250
takes advantage of its massive power
supply to shield the Gold Note 1000 series of electronics
from electro-magnetic noise thus insulating it effectively
from the external AC power system.
The large, ultra-clean power delivered will enhance ultra-
low noise, greater dynamic, better resolution and finer
details for a realistic high-end audio performance and pure
audio pleasure.
POWER
Mains supply: 100-120V / 220-240V with automatic
selection, 50/60Hz
Total Power Reserve: 1250W

QUICK START
INSTALLING THE PSU-1250 IS SIMPLE AND TAKES ONLY A FEW QUICK STEPS
1. Turn OFF the MASTER SWITCH on the Gold Note 1000 series of electronics and remove the power cord
2. Connect the PSU-
1250
to the AC power outlet using the supplied power cord
3. Connect the PSU-1000 to the Gold Note 1000 series of electronics using the supplied cable PSU LINK cable
(from the PSU OUT on PSU-
1250
to the PSU port on Gold Note 1000 series of electronics)
4. Turn on the MASTER SWITCH on the rear panel of the PSU-
1250
.
PSU-
1250
is designed to work in client mode with any electronics of the Gold Note 1000 series: turn ON the MASTER SWITCH
of the PSU-
1250
to put in stand-by the unit it is powering.
Every time the PSU-
1250
is in stand-by, the unit it is powering will go automatically in stand-by [display OFF and LED OFF).
If you need to turn OFF the unit powered by the PSU-
1250
, simply turn OFF the MASTER SWITCH on the PSU-
1250
.
The Gold Note 1000 series of electronics will show the PSU-
1250
is connected by showing the PSU icon on the display or by
