Nobsound NS-15G Mini Bluetooth Digital Amplifier, HiFi Stereo, 100W+100W Output, TPA3116D2 Chip, 19V Power Supply Included, Glossy Aluminum Housing

High-Efficiency 200W Drive with Dual TPA3116D2 Chips: Equipped with two Texas Instruments TPA3116D2 power amplifier chips, this amplifier delivers a combined maximum output of 300W at a 4Ω load and 200W at an 8Ω load. Its unique multi-phase synchronous rectification technology achieves 89% power efficiency, a 30% improvement over previous models. When using the included 19V DC power adapter, it can easily drive 3-inch to 10-inch speakers (20-200W). It faithfully reproduces everything from the explosive bass of rock to the delicate high notes of classical music while suppressing the heat generated by Class-D amplifiers.

Multifunctional Bluetooth 5.0 + Tone Control: The built-in Bluetooth 5.0 chip has a communication range of approximately 15m and supports AAC/SBC codecs, allowing you to wirelessly play music from your smartphone. Dedicated treble (±10dB/10kHz) and bass (±10dB/100Hz) adjustment knobs allow for sound tuning to suit room characteristics and music genres. Bypass mode ensures a clean signal path with THD of less than 0.01%, ensuring pristine sound reproduction.

Reliability with Professional-Grade Connection Terminals and Protection Circuitry: Pure copper gold-plated banana plug terminals (25A current rating) prevent increased contact resistance due to oxidation. Spark prevention circuitry is standard on the input side, and short-circuit, overtemperature, and overcurrent protection (SCP/OTP/OCP) are standard on the output side. A built-in soft-start function completely eliminates pop noise when powered on, protecting the speaker cone. Intuitive user-friendliness: Red and blue LED indicators allow you to check the input mode (AUX/Bluetooth) at a glance. The 32mm diameter machined aluminum volume knob provides a moderate operating torque of 0.5 N·m. The front-panel tone bypass switch allows you to change the EQ setting with a single touch, instantly creating a listening environment that prioritizes immersion.
