Special Features

2.1 Bluetooth Amplifier — Dedicated L/R channels plus a true sub channel deliver room-filling stereo with deep low end. Bluetooth 5.0 with aptX-HD/AAC gives stable, near-lossless wireless from phones, tablets, and laptops.
600W System Power — Up to 300W×2 for L/R and 300W for the sub to drive bookshelf or floorstanding speakers with headroom. Includes a 48V/5A adapter; supports DC 24–48V for flexible power and stronger dynamics.
Subwoofer Output — Dial in tight, seamless bass using the variable crossover (50–220Hz) and ±4dB sub gain. Blend your sub with mains to avoid muddy mids and get punch for movies, music, and gaming.
Dual TPA3255 — High-efficiency Class-D power with low distortion (0.01% THD at 1kHz) and ≥108dB SNR for clean transients and black backgrounds. Three-sided ventilation and dual power sockets enhance reliability.
Bass & Treble Control — ±6dB tonal shaping lets you tame bright recordings or add warmth at low volumes. Premium caps, enclosed Taiwan pots, and copper-shielded inductors ensure clarity and durability.
