Users Guide and Specifications AMP2X15 Audio Amplifier Board PUI Audios AMP2X15 audio amplifier board features a Texas Instruments TPA3110D2 Class D amplifier circuit for maximum signal fidelity delivering 6 Watts per channel of low-distortion power (0.1% THD+N) into 4 loads 15 watts per channel into 8 loads (10% THD+N with 16 VDC supply). The AMP2X15 is purpose-built to aid and assist engineers in prototyping audio solutions for a multitude of applications, and offers single-ended and differential inputs with stereo BTL or mono PBTL outputs. Features: Small form factor76.2mm x 50.8mm x 20mm (L x W x H) Wide +9.5V to +20V DC input range (power supply not included) Three different input connectionsstereo 3.5mm jack, terminal blocks, six-circuit Molex SL 70543 connector Audiophile-grade sound quality Single-ended and differential inputs stereo or mono output Built-in over-current and over-temperature protection Note: Please read this manual carefully before using this product. To keep the product in the best working condition, please operate it according to the relevant steps. Warranty is void if this product is misused. Please read this manual carefully before you use the product. A DC power supply with 9.5V to 20V output (and a minimum of 2A of current capacity) is recommended to be used to power this product. Safety Precautions: 1. In order to achieve the best sound quality, please use a stable power supply. A bad or unstable power supply will reduce the sound quality or even damage the amplifier board. 2. Avoid metal objects coming into contact with this product. Protect the solder joints on the bottom of the PCB when mounting this product. 3. Do not connect a pre-amplifier to the input of this product. Enough gain is provided to allow the amplifier to develop maximum power output. Doing so may damage the amplifier. Ensure the audio input signal is at a minimum when powering on the amplifier, to protect the amplifier and connected speakers. 4. Never expose this product to rain or extremely humid (>95% relative humidity) environments to prevent fire or electric shock. PUI Audio, Inc.
