It pairs high continuous output with user controls for tone shaping and on-board safeguards to protect the circuit and connected speakers. The board ships in black and accepts common DC barrel adapters, making it easy to integrate into existing setups.\u003c\/p\u003e\n\n\u003ch3\u003eHow much power can this amplifier board actually deliver?\u003c\/h3\u003e\n\u003cp\u003eThe ZK-1602T uses the TDA7498E chip to provide up to 160W per channel into suitable speaker loads, totaling 320W peak stereo output under optimal conditions. Real-world power depends on supply voltage, speaker impedance, and thermal management.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePeak output: 160W × 2 channels (chip-rated)\u003c\/li\u003e\n  \u003cli\u003eRecommended supply: 15–36V DC for reliable performance\u003c\/li\u003e\n  \u003cli\u003ePower dependent on speaker impedance and heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tone controls and audio adjustments are available?\u003c\/h3\u003e\n\u003cp\u003eThis board adds separate treble and bass knobs so you can shape the high and low frequencies independently of the master volume.
