Our Non-oversampling DAC
using the TDA1545A
chip with Asynchronous Relocking, Passive I/V stage. Output transformer
coupled
Features
Our own silver pulse transformer
(this separates the ground thus resulting in a quieter music) to couple
the digital output of your cdp into our DAC. Our nickel core
transformer is wound on a 2mils lamination (0.05mm).
Therefore the digital ground is
broken up between the DAC and the Transport/CDP to allow a cleaner
presentation as the grounds are isolated
Dedicated pre and post regulator (for each
chip) to bring down the noise floor
Specially wound Balanced power transformer
to power DAC, this is the same winding topology as our balanced power
supply. This further brings down the noise floor. The power transformer
is wound on a M6 core
Dedicated windings on the power transformer
for the digital power supply and the analog power supply. This is NOT
shared to prevent the transfer of digital noise to your precious analog
power supply.
The power transformer is fitted with MULTIPLE
electrostatic shields to prevent the spreading of the noise cause by
digital circuits. This electrostatic shields shunt noise to ground thus
keeping the power supply clean
Asynchrous reclocking to 100Mhz. Clock
module is place below the PCB to prevent spraying the board with noise.
The clock module is located at the bottom left end of the PCB. The
clock has its own dedicate power supply to decouple the noise generated
from the clock
The DAC is design around a good power supply
system
IN the digital segment there is a master
regulator and then its is fed into local regulators individually
finding the IC. SO each digital IC is totally isolated from another
digital IC
The Opamp segment is run again with its own
local discrete regulator. This keeps the noise isolated between left
and right op-amps
Selectable gain structure of 1.25volts out,
2.2volts out and 4 volts output. This allows user to optimize their
gain structure. This can be change by the user by opening the unit and
selecting the right jumper on the board
On the output, output transformers is used
to couple the analog voltage from the DAC to the outside world. This
way the DAC is impedance match to your down line equipment. This output
transformer is wound on a M6 core
Chassis for the DAC is built on our tune
wooden Merbau wood with Stainless Steel plate similar to our TVC
construction
Our new Neotech 7N copper for internal
wiring Teflon wires for power
Pure Silver RCA used for digital input and
analog output
