Key Features

🎵 Dual TPA3255 Flagship Chips

Texas Instruments’ top-tier Class-D amplifier chip. Ultra-low THD of 0.006%, efficiency above 90%, and up to 315W per channel in stereo mode — a massive step up from TPA3116/TPA3221.

🏛️ 5-Knob Independent Control

No master volume — each knob controls a dedicated parameter: Sub Frequency, Sub Volume, L&R Treble, L&R Bass, and L&R Volume. Full control, zero compromise.

🔊 Full-Range L&R Output

Left and right channels output a complete full-range signal with no low-frequency roll-off. Compatible with full-range drivers, 2-way, or 3-way speaker systems.

⚡ Wide Voltage Input (19V–51V)

Scale your power output by adjusting supply voltage. From 19V for casual listening to 48–51V for professional-grade performance in large spaces.

🛡️ Multi-Layer Protection

Built-in over-temperature, over-current, over-voltage, short-circuit, and reverse polarity protection — keeping your speakers and board safe at all times.

🔧 DIY-Friendly Design

Pre-soldered IPEX Bluetooth antenna connector, screw-terminal speaker outputs (no soldering needed), and an optional detachable panel (S600X-W) for clean enclosure integration.

Power Output by Channel

Channel Peak Power Typical (24V / 4Ω)
