8-Channel Internal Quad DAC
The ES9038PRO DAC incorporates the latest 32bit HyperStream® II technology from ESS, delivering the best dynamic range in the industry and a highly-pure sound by realizing an extremely-low THD+N value even at low-amplitude signals. An 8-channel internal quad-DAC separates the eight channels for precise sound control, and each channel is converted via the four internal DACs to deliver a clear, noise-canceled signal so that you can enjoy a perfect sound close to the original source.
Rich, Clear Sound via High-Quality
4.4mm Balanced Output
The 4.4mm balanced output, the new standard in high-fidelity audio, supports richer output than the conventional 3.5mm unbalanced output. Greater left-right channel separation prevents crosstalk between left and right audio signals to deliver a very clear, realistic sound without distortion or loss. Balanced output effectively blocks noise generated when signals are transmitted by adding 'out of phase' signals to unbalanced output signals. Since it transmits two types of signals simultaneously, the PLENUE L strengthens the output signal for clearer and crisper reproduction of original sound. The PLENUE L uses 4.4mm balanced output to reproduce crisp original sounds. Ultra-Low Noise LDO Power
for High-Performance Audio Systems
The PLENUE L offers high PSRR(Power Supply Rejection Ratio) performance and very low noise via an ultra-low-noise LDO(Ultra-Low Noise Low DropOut Regulator) power circuit designed for high-performance audio systems. Optimal Digital Path
for 32bit, 384 kHz via Independent CPLD
We developed an optimized digital path circuit that supports 32bit, 384 kHz sound sources and equipped the PLENUE L with an independent CPLD(Complex Programmable Logic Device), which supports fast operations and minimizes noise by optimizing bus and group unit digital signal processing.
