Fanmusic SMSL SU-2 Decoder High Resolution ES9039Q2M 4 op-amp chips OPA1612A THD+N 0.00006% SINAD 123.5dB DAC

• Four high-end operational amplifiers. The SU-2 features four high-end operational amplifiers, the OPA1612A, arranged in a symmetrical architecture within the DAC and analog amplification sections. This design does not merely stack components; instead, it creates a signal path with low distortion and a high common-mode rejection ratio through precise matching and independent adjustments. The goal is to systematically minimize crosstalk and noise at every stage, ultimately achieving high-fidelity linear amplification of signals across a wide bandwidth, ensuring dynamic and subtle audio details are preserved.
• Stable Connectivity, Supports AES/EBU input and XLR output. This system features a professional AES/EBU digital interface and fully balanced XLR output. This combination ensures low distortion and high common-mode rejection, establishing a stable connection for smooth audio delivery. The integration of AES/EBU and XLR is not just about the interface configuration; it embodies a comprehensive signal philosophy.
• Indicator System, Measure every moment accurately. The standby indicator emits a warm light, signifying the equipment's quiet standby mode. The input indicator clearly marks the selected signal source, allowing for path visualization. The signal detection indicator captures the moment each digital stream arrives. The left and right channel indicators reflect soundstage balance in real time, while the sampling rate indicator acts like a technical instrument, converting abstract data precision into intuitive visual cues. This extension of sound ensures that every listening experience remains under control.
• Specially designed for monitoring purposes. The fully balanced design of the SU-2 is ideal for connecting active monitor speakers, allowing for a transmission distance of more than 30 meters using AES/EBU input.
