The CDP 300 is the first Blacknote CD player
made with a double front panel and the innovative extra large alpha
numeric display. The CDP 300 is designed around the newest digital
devices today available.
The Digital to Analog stage is managed thru
customized DACs made by AKM (Japan) and Burr-Brown (Texas Instruments,
U.S.A.). The proprietary circuit design of the DAC enable the CDP 300
a real 24 bit resolution with the over-sampling 368 higher than the
standard CD players (44,1KHz).
The high quality of the Digital to Analog
converters and the Blacknote proprietary circuit design allow to reach
a sonic performance hardly available from “standard” CD
players. The Clock generator is designed around the Burr-Brown PLL1705
microchip. The PLL1705 is able to generates a very low jitter phase
error, one of the lowest today available: 50-12 (50.000 billions of
second).
The power supply is made with four different sections and
managed thru four dedicated custom transformers. Any transformer supplies
the power directly to the Digital Stage, the Analog stage, the Transport
and the other CD Player powered stages including the display.
The whole
power supply is stabilized and rectified with sophisticated and over
dimensioned Current Generators exclusively made by Blacknote.
The extra
large alpha numeric display can be customized and switched off during
play mode in order to stop working any voltage power dedicated inside
the unit.
All the functions and operativity of the CD player are controlled
with the latest generation Texas-Instruments microchip programmed with
a dedicated software able to manage any eventual necessary future up-grade
of the unit.
The Analog Power Supply is managed thru four OP chips
singularly powered with a special multi inductive power supply.
The
Power supply dedicated to the mother board and the DAC board is decoupled
thru two “fused silicon” transformers specially shaped
by Analog Device.
The CDP 300 features a sophisticated tube analog
output stage based around two 6922 tubes. Such new output stage is
a true balanced tube design no-matching any transistor or j-fet in
order to get the highest sonic performance.
The transport mechanism
is of the drawer type and is designed to achieve the disc rotation
stability at its best with a proprietary circuit, the Natural-Speed™ able
to manage the speed of the disc down quite as much as an analog turntable.
The Natural-Speed™ also tunes the transport motor in order to
virtually erase the generated spinning vibrations.
