Review on Nobsound Dual TPA3116 Digital Power Amplifier - High-Fidelity Stereo Amp With NE5532P Pre-Amp, Audiophile-Grade 2.0 Channel And 100W×2 Output (Black) by Matthew Harris
NOT 100Wx2! Needs 4 ohm speakers for reasonable volume.
Tested the outputs on a scope and see clipping at 10V pk with the factory 19V/4.7A supply. This is equivalent to about 6Watts RMS into 8 ohms. Check the TI data sheet for TPA3116D2 and they spec 100W only for 2 Ohm load with bridged output, with max 25V DC supply. Bottom line - if you use this with 8 ohm speakers, and factory 19V DC supply, dont expect to rock out, use 4 ohm speakers and 25V DC supply for reasonable volume that you would expect from any medium power stereo. Also - ordered replacement factory power supply and it came DOA, apparently an empty plastic shell with no electronics inside haha.
- Reasonable circuit, concise wiring layout and perfect protection, no sparks no shock. Adopting NE5532 op amp with ultra-low distortion and dynamic balanced, the sound is very smooth and natural, powerful in low frequency and delicate in high frequency, full of music styles.
- The amplifier may not be able to deliver the same level of high-fidelity audio as more expensive models on the market.
