35W D50 Optical Bluetooth Amplifier Board

Physical dimensions: 15.5 cm (L) × 4.5 cm (W) × 5 cm (H). Built on durable black PCB substrate. Rated output: 35W (D50 Class-D architecture). Supports three power options: DC 12V, DC 24V, and AC 220V input — no external transformer required. Audio inputs include TOSLINK optical, Bluetooth 5.0 (implied by 'Bluetooth Audio' and common implementation), and unspecified analog line-level sources. Tone shaping is achieved via two dedicated physical potentiometers: one for high-frequency boost/cut, another for low-frequency (subwoofer-relevant) adjustment. Thermal management prioritises longevity: low heat generation enables silent passive cooling — ideal for enclosed installations or space-constrained builds. Package includes remote control for convenient volume/tone access, speaker cable, DC input cable, EU-plug AC power cable, and the amplifier board itself. Designed for European and Indonesian 220V electrical standards. No UK or US plug — EU plug only. Not intended for 110V regions without external step-up transformer (not included). Colour representation may vary slightly due to screen calibration and lighting conditions.
