High-Power Stereo Amplifier Board TDA7498E — Bluetooth-compatible 5. 0, 150W*2, Treble & Bass Adjustment, Multiple Modes

Overview: This high-power stereo amplifier module uses the TDA7498E Chip to deliver stable, high-fidelity sound with low distortion and low noise. It supports 2.0-channel stereo output at 150W*2 (left and right channel) and reproduces crisp highs, smooth mids, and powerful, punchy bass. Tone Controls: Dedicated Bass and Treble knobs let you shape the sound — turning the Bass knob clockwise raises low frequencies and counterclockwise reduces them; the Treble knob works the same way for high frequencies. The front panel also includes high/low tone adjustment knobs plus a volume/on-off knob. The main control employs a high-end amplifier rotary encoder for 360-degree infinite tone adjustment and smooth one-button start/stop operation. Wireless & Inputs: The board features Bluetooth-compatible 5. 0 wireless input with a transmission range up to 15 meters (unobstructed). It also has an AUX input. When an AUX cable is inserted the unit will switch to line input automatically — Bluetooth-compatible mode has the lowest priority. Protection & Reliability: Built-in safeguards include overheat protection, undervoltage protection, and short-circuit protection to help prevent damage and ensure reliable performance even at high output levels. Thermal Design: A large-area heat sink (463715mm) combined with thermal conductive silicon paste and close contact to the copper-clad shell doubles the effective dissipation area to support continuous high-power operation. Compatibility: Bluetooth-compatible pairing works with smartphones, tablets, laptops and similar devices. AUX input accepts MP3 players and other line-level sources. The amplifier can drive both passive and active speakers.
