First of all, the actual output power of 3116 is not as large as the propaganda, 50W is only the power under the impedance of 2 euros, and the household speaker is basically 8 euros, so it is only 12W. 2030A is stronger than it, 1875 can put 3116 down on the ground grinding, secondly, 3116 peripheral components, especially the quality of the output inductor impact on the sound quality is particularly serious. I have a single power supply of BTL 2030A and 3116 power amplifier board, the sound quality can be said to be different, but with the same 140W switching power supply, the output power of the former second kill the latter.
tda3116 sound quality is good, equipped with 6.35MMIRS balanced input interface, can be connected to mixers, mixers and other professional equipment, support standard 4dBu input sensitivity, build a small music production system.
Adopts high-quality ADC conversion chip, signal-to-noise ratio up to 99dB, with TI digital power amplifier Tda3116, and uses its built-in DAP to complete sound adjustment, to ensure excellent performance under dual-mode. Paired with a 1-inch silk diaphragm unit, the special coating ensures a delicate and natural treble.
I think the sound quality is good. When using this series of chips, it is recommended to use differential signal input, and use its enable pin, to add startup delay, power down advance circuit. Can effectively eliminate the impact of switching machine.
