Dual Decoding Systems:
System 1: Equipped with a TDA1307 and dual TDA1547 chips, this section delivers a classic, retro sound signature that appeals to audiophiles who appreciate a warmer, more analog sound.
System 2: Utilizes 4 x ESS9039SPRO DAC chips to provide ultra-high resolution and precision, offering a modern sound profile that maximizes detail and clarity.
Selectable & Automatic Mode:
Users can manually select between the two decoding systems depending on the audio signal format. For added convenience, an automatic mode is available that detects the format of the digital signal and selects the appropriate decoding system.
Clocking System:
The Pearl 30D integrates a synchronized clock system with extremely low phase noise to ensure precision in digital signal processing.
Features an external reference clock input interface (10 MHz) and a synchronous clock output interface that allows connection to an external clock. It can also act as a synchronization clock source to align the system clocks of various connected digital devices, improving playback quality across the entire system.
Power Supply Design:
The Pearl 30D employs a split power supply system, enhancing the separation of power and signal circuits. This advanced design uses complex rectifier and filter circuits to achieve an extremely clean power supply, minimizing interference.
The power system also features a superlinear voltage stabilization circuit made up of six groups of discrete components, alongside LT1963 linear voltage regulators that offer ultra-low noise and stabilize high-voltage power for optimal performance.
Jitter Elimination Technology:
The Pearl 30D incorporates a full-channel digital audio jitter cleaner to reduce jitter in SPDIF and IIS signals, significantly improving the overall sound quality.
It also employs stable impedance matching and RF coaxial cable transmission for minimal signal loss, reduced waveform distortion, and suppressed jitter.
