SOULNOTE D-3 D/A Converter

SOULNOTE D-3 D/A Converter

The ultimate D/A converter with ZERO asynchronous circuits
* This unit will not operate unless connected to a 10 MHz external clock generator like the X-3. The X-3 is sold separately.

The D-3 utilizes a dual monaural construction that employs two identical and dedicated sets of terminals, Type-R circuits, power supply channels, power transformers, relay drive circuitry, and relay power supplies for the left and right channels. It is also fully separated from the digital power supply, including the transformer. A photocoupler completely separates the relay control signals that connect with the analog signal system. The mounting base for the aluminum circuit board is not fixed, laying the foundation for uninhibited and more impassioned sound quality. Analog circuit boards are mounted on independent right and left circuit board chassis and are also independent from the rear panel connectors. Similar to the P-3, foaming Teflon-covered cables connect the left and right independent side aluminium ground anchors to the respective aluminum ground anchors that are isolated from the chassis.

Temperature settings
The circuit current in SOULNOTE products relies on solutions with the highest emphasis on sound quality and safety. Functionality and sound quality generally improve when the transistors operate at higher temperature.。
Anti-vibration housing
SOULNOTE products place the highest emphasis on sound quality, so the top cover, chassis, and other components do not employ vibration isolation.
Regarding use of electronic equipment cleaners and contact rejuvenation products on SOULNOTE products
Commercially available electronic equipment cleaners and contact rejuvenation products could damage the resin components of SOULNOTE AC inlets. Do not use these types of chemical products on SOULNOTE equipment.
