A new digital link: "ES-LINK3"
The P-02 and D-02 have support for Esoteric's original transmission format "ES-LINK3" and can perform a maximum 48-bit/176.4kHz broadband PCM digital transmission (*1) using two XLR cables. These models also have support for "Dual AES 8Fs" standard (maximum 24-bit/352.8kHz) (*2). These models can also perform conventional Direct Stream Digital (DSD) transmission and direct DSD-to-analog conversion processing for Super Audio CD (SACD) playback.
*1 The D-02 can handle inputs of signals up to 48-bit/192kHz. *2 The D-02 can handle inputs of signals up to 24-bit/384kHz.

Clock module and Power supply (P-02)
Abundant use of high-grade components in design
Esoteric has made maximum use of high-grade components for the internal construction of the P-02 and D-02. A total of eight independent Esoteric toroidal core power supply units are installed in the combined system to supply clean and stable power to each circuit. The inside of the chassis has our multiple layer structure that is partitioned into 5 sections. Each circuit block is assembled in a dedicated compartment and placed three-dimensionally, in order to minimize interference between circuits and to achieve the shortest signal paths. The exterior is constructed with aluminum and a 5mm gauge steel bottom chassis, supported at four points with Esoteric pinpoint feet (patent No. 4075477). This four-point system effectively suppresses vibration, reduces resonance and assures extremely high rigidity.
ADVANCED TECHNOLOGIES
Isolated clock technology
The P-02 and D-02 adopt an isolated clock technology that completely isolates the clock circuit from other circuit blocks. The clock module is equipped with a dedicated toroidal core power supply. The ground of the clock module is isolated from other circuits. As a result, this module
Clock module and Power supply (D-02)can supply pure clock signals to the system by completely minimizing the occurrence of random jitter that results from power voltage or ground voltage fluctuations.
The clock module adopts high accuracy (+/-0.5ppm, at our factory prior to shipment) Voltage Controlled Crystal Oscillators (VCXO). DAC modules and clock module are hard-wired using special coaxial cable supplied with gold-plated SMA connectors, keeping transmission losses of the audio clock to an absolute minimum.
Digital Audio
22.5792MHz Master Clock
Direct master clock Link without PLL
The clock sync between transport and DAC is a well established jitter reduction system, but further advanced with a new technology called the “Direct Master Clock Link".
With the previous clock sync system, the reference clock (master clock) of the digital audio output is generated by the transport, being synchronized to D/A processing by using PLL (Phase Locked Loop) circuits. Esoteric's new "Direct master clock link" system is simpler and more consistent for clock signal integrity. The 22.5792MHz master clock generated by the DAC is supplied directly to the transport, therefore there is no need for re-clocking at the PLL circuit. Pure and direct clocking makes sound much clearer with more accurate focus and imaging.
10MHz clock input / wide-ranging clock options
A conventional WORD clock (44.1kHz, 88.2kHz, and 176.4kHz) sync setting is also selectable, and the system can be upgraded by adding Esoteric’s external rubidium master clock generator. Both the P-02 and D-02 are equipped with a 10MHz master clock input jack for connecting a 10MHz-output clock system. You can connect the units to a wide variety of optional external clock generators for upgrading incrementally to a higher quality Esoteric sound system.
