Product Description

NSTE-2045 is a highly efficient, compact, two-channel Class D power amplifier designed for audio systems such as motorcycles, electric vehicles, UTVs, and ATVs, which have strict requirements on size while requiring both weather resistance and sound quality. The output power per channel is 45W RMS (4 ohm load, 14.4V power supply), and the total harmonic distortion is controlled within 1%, ensuring clear and full sound quality, meeting the needs of daily entertainment playback and commuting. Its operating frequency range covers 20Hz to 20KHz, fully restoring the full-band sound effects, with excellent performance from low-frequency shock to high-frequency details. In terms of safety protection, the NSTE-2045 is equipped with overheating, overload, and short-circuit protection mechanisms, which can automatically cut off the power in the event of electrical anomalies or excessively high ambient temperatures, effectively avoiding equipment damage and extending the product life.
