The kit uses a TPA1517 stereo audio power amplifier that contains two identical amplifiers capable of delivering up to 6W per channel of continuous average power into a 4Ω load at 10% THD+N or 5 W per channel at 1% THD+N. The gain of each channel is fixed at 20dB. This kit uses the 20-pin thermally enhanced DIP package (NE). Paradigm Technologies have designed a fully symmetrical PCB around the TPA1517 chipset to ensure that maximum performance is obtained.
