+/-20-26VAC LM3886 + C1237 BTL 2.0 Amplifier Board 2*100W

+/-20-26VAC LM3886 + C1237 BTL 2.0 Amplifier Board 2*100W

Using original LM3886TF.
- Front input capacitance capacitors using CBB top 4.7UF, electrolytic capacitors used in Taiwan brand signals the main loop , the main filter capacitor using the NOVER pitched audio-specific capacitance 2 × 10000UF, using domestic flat bridge rectifier 25A and above , to ensure a steady stream of strong power support.
- Resistor selection of rings metal resistance , the main circuit employs a precision of ± 1% metal film resistors rings , ensure the machine a good signal to noise ratio .
- 1.6mm thick sheet using double-sided PCB , 2.0 oz copper thickness , HASL whole process to ensure that the size of the current through the good performance . PCB -class quality .
- Using current advanced C1237 BTL speaker protection circuit, effectively eliminating open, shut down the impact sound and DC output protection features that make your speakers more secure.
- The board uses BTL mode output because BTL output voltage higher than the parallel , if at the same time when the 8 ohm speaker will be twice the size of the parallel BTL output power ! Since 3886 , only a single output power 50W, 50W many 3886 enthusiasts of this power can not meet the need, it is particularly the launch of the high-power 3886 2.0 boards !
- The entire circuit board trace layout are very strict and reasonable, the overall PCB traces using a little grounding. The amplifier board is stable and reliable output power ; beautiful mellow sound , open sound field . Dimensional sense of strong , powerful low-frequency sound calm , very good signal to noise ratio , wide dynamic range ; details clear, excellent transient response , playing all kinds of music were afloat in the family environment is very good playback performance .
