Qlearsoul HiCore H2 Bluetooth 5.4 Hi-Fi Stereo Amplifier — TI TPA3255 Class D, 100W x2 (@4Ω) Rated Output, Anti-Hijack BT Mode, RCA/AUX/BT 3-Input Hub for Passive Speakers, Includes 30V/5A Adapter

The Qlearsoul HiCore H2 is a compact Class-D stereo amplifier built around the Texas Instruments TPA3255 chip — a platform trusted by audiophiles worldwide for its low distortion and high efficiency. Delivering a stable 100W x2 (@4Ω) output with the included 30V/5A adapter, the H2 brings clean, controlled power to any passive speaker setup. What sets the HiCore H2 apart is its Anti-Hijack Bluetooth Architecture. Whenever you switch to RCA or AUX mode, the H2 physically cuts the Bluetooth signal — preventing neighbors or guests from accidentally hijacking your stream. A quick 2-second long-press on the smart knob instantly wipes all pairing history. Your audio. Your rules. Featuring a triple-input hub (Bluetooth 5.4 / RCA / 3.5mm AUX), the H2 connects effortlessly to your turntable, TV, PC, or smartphone. The CNC-machined aluminum chassis with side-vented passive cooling and non-slip silicone base ensures stable, long-session performance without a fan. For enthusiasts who want more headroom: the H2 supports DC 24V–51V input, unlocking up to 300W x2 peak potential when paired with a higher-voltage PSU. NOTE: Maximum output depends on the power supply voltage and current.

• Anti-Hijack Bluetooth Hub — Connects via Bluetooth 5.4, RCA, or 3.5mm AUX, making the HiCore H2 the central hub for your turntable, TV, PC, or phone. Uniquely, switching to RCA/AUX mode physically cuts the Bluetooth signal, blocking unwanted pairing. A 2-second long-press on the knob wipes all pairing history instantly.
• TI TPA3255 Hi-Fi Performance — Powered by the proven Texas Instruments TPA3255 Class-D chip, the H2 delivers a clean, stable 100W x2 (@4Ω) output with ≥95dB SNR and ≤0.1% THD+N. Paired with the included 30V/5A adapter for reliable plug-and-play performance right out of the box.
• Expandable Power Architecture — The H2 supports a wide DC 24V–51V input range. The standard 30V/5A adapter is optimized for stable daily listening. Upgrade to a higher-voltage PSU to unlock the TPA3255's full 300W x2 peak potential. NOTE: Maximum output depends on power supply voltage and current.
• Intuitive Smart Knob & Dedicated Tone Controls — The multi-function volume knob lets you rotate to adjust volume, short-press to cycle input modes, and long-press (2s in BT mode) to clear all pairings. Separate Bass and Treble knobs give you precise, independent tone shaping without diving into menus.
• Compact CNC Aluminum Build with Passive Cooling — The precision-machined aluminum alloy chassis with side-vented passive cooling keeps the H2 whisper-quiet and thermally stable during long sessions — no fan noise. Non-slip silicone feet ensure steady placement on any surface. At just 17×13×10cm, it fits neatly on desks, shelves, or TV consoles.
