1, TDA7293, TDA7294, LM4766 (approximately equal to LM1875*2), LM3886 is simulated; TDA7498ET, TDA8590 (TDA8950) are class D (so to speak numerical); If there is no requirement for power consumption and heating, you can choose a traditional analog circuit, otherwise please choose Class D. As for sound quality, the style is different, but I lean towards the D category, with clean lines,Low heat, low power consumption, high sound reduction.
2. I feel that Italian TDA is bolder. The 7293 parameters are much better than the 7294, but it's not easy to buy. TDA7296 is a new DMOS high power audio power amplifier integrated circuit from STPC. It is the same pin as the TDA7293TDA7294TDA7295 and has a wide operating voltage range. High output power (up to 60W output power), silent standby function, low noise and distortion, overheating and short circuit protection.
3, the price is different and the performance is different. The price is different,Parameters , the power amplifier chip is Toshiba TB2926HQ< /strong> tda7854 power amplifier chip parameters , now bought ST's TDA7850, it is recommended that you first match the next parameters. Hope I can help you.
2, there is no need to change, check the data that TB2926 performance and TDA7850 is almost the same.
3, tb2926hq Good. The power amplifier of this brand, its factor in the volume effect and clarity, and her wedding dress effect, its low high throw distribution rate effect. In addition, the material of its power amplifier, the function on the host, and its life, and the safety factor have reached the domestic standards. In addition, the tda7854 power amplifier chip parameters His civil and commercial above is very extensive, and has been recognized and liked by everyone and businesses. tda7854 power amplifier chip parameters His after-sales is guaranteed by quality.
4, 4. Nevertheless, it is necessary and possible to improve the sense of hearing and make it more comfortable to express as much detail as possible. Like the enthusiast said the details are emptyThe details of breathing singers singing ventilation, low frequency diving weight and thickness speed can be easily achieved under the push of the car, and because people are in the sound field, the hearing feeling is more similar to the feeling of headphones.
5, tda7384 4X35W car audio power amplifier ic. Can use the same 25-pin, the same company's tda7388, 4x41W, or tda7850 4x50W power amplifier ic, directly replaced. The tda7850 is recommended, and the power filter capacitor is upgraded from the original 470uf to 2200Uf, because the amplifier power is increased.
1, suitable for heavy bass power amplifier integrated circuits are: LM388TDA729TDA7294 audio power amplifier integrated circuits. Heavy bass power amplifier is often used in the need to change the original 0 power amplifier system to 1 (stereo + subwoofer) system, generally by the pre-stage amplification, low-pass filtering, phase adjustment, power amplification, protection and power supply components, the use of integrated circuit can simplify the circuit, can be madeFailure rate and cost reduction.
2, field block: STV9379 TDA4864 TDA8177 TA8403 TDA8359 STV9302 LA78040, etc. Sound: LA4282 TA8213 TDA2009 TDA7266 TDA7264 TDA7057 TDA8946 TA2008 too much etc.
3. Yes, TDA7850 TDA7385 TDA7381 TDA7384 TDA7386 TDA7388, TA8263BH, TA8264AHQ, TA8266HQ, TA8275, TA827TB2929, TB2939.
1, MG 6 has power amplifier. The MG 6 is powered by a 5 engine with a maximum output of 133kW and a maximum torque of 285Nm.
2, watts. According to Mazda's official website, the sound speaker inside the Ma 6 spare tire gun is a 6-inch caliberThe maximum power output of the speaker is 100 watts. Mazda, also known as Mazda Motor Corporation, is a Japanese multinational automobile manufacturer listed on the Tokyo Stock Exchange (TYO) and ranked 400 on the Fortune Global 500 in 2020.
3, set the MG 6's 80 Hz to 5,500 Hz to 6, 1 KHZ to 7,5 KHZ to 5,16 KHZ to 4, and then set the sound field balance to the rear 2, so the effect of adjusting the sound effect will be better, but everyoneIt is best to adjust the sound effect to be more comfortable because of the different senses of music. The role of car audio Car audio can reduce the boredom of travel for drivers and passengers during the journey.
The TDA7850 is favored for its greater power and more prominent bass effects, while the TDA7854 is known for its lower distortion. However, whether it is the choice of domestic or imported, the key lies in the quality, the price may not vary much. In capacitance selectionOn the other hand, the original 10000UF capacity is slightly larger, and some users' feedback shows that the effect decreases after replacing it with 10000UF of Japanese ruby.
No need, no point! TB2929HQ, TDA7850 or TDA7854 are power amplifier ics that have nothing to do with sound quality.
tda7384 4X35W car audio power amplifier ic. Can use the same 25-pin, the same company's tda7388, 4x41W, or tda7850 4x50W power amplifier ic, directly replaced. tda7850 is recommended, and replace it at the same timeThe power filter capacitor, from the original 470uf, is upgraded to 2200Uf, because the power amplifier is increased.
