• ♪ Fully Balanced Discrete PLFC+ Circuit: Adopts SMSL proprietary discrete-component Precision Linear Feedback Circuit architecture. It achieves ultra-low distortion with THD+N as low as 0.00007% and SNR up to 131dB, delivering a quieter noise floor and richer musical micro-details for audiophile-grade listening. Frequency response ranges from 20Hz–100kHz (-0.5dB)
• ♪ High-Power Linear Power Supply & Relay Volume Control: Equipped with a built-in high-power toroidal linear power supply to reduce background noise. Precision relay volume control preserves consistent left-right channel balance and supports remote volume adjustment. High-precision low-temperature-drift resistors deliver steady performance across varying operating temperatures
• ♪ 3-Step Switchable Gain Control: Low / Medium / High gain modes available. Low gain is specially optimized for sensitive IEMs to minimise over-driving and background noise, while high gain easily drives high-impedance over-ear headphones and planar magnetic headsets
• ♪ Pre-Out Function for Multi-Scene Audio Setup: Works as both standalone headphone amplifier and high-end pre-amplifier. Connect active speakers or power amplifiers via Pre-output. Supports XLR balanced & RCA single-ended analog input to pair with DAC, streamer and other audio sources
• ♪ Silent Circuit & Headphone Protection: Built-in high-quality relay mute circuit for shock-free silent power-on. Comprehensive safety protection including DC offset, overvoltage and overload protection for headphones
