LM3886 Dual Channel Amplifier Board with LM833 op Amp Complete Board

Description

Introduction

This product power level integrated amplifier board before and after the 2 x 68W dual channel, LM833 tone warm, balanced atmosphere, often used as a preamplifier; LM3886 is the United States National Semiconductor (NS) a long prestigious high-performance audio power amplifier integrated circuits. The maximum output power up to 68W sound vivid and accurate, are quite low noise and distortion, and the protection function is improved, stable performance. The LM3886 has been launched to great acclaim, and soon become large and medium-sized power HIFI audio amplifiers and high-fidelity active monitor amplifier configuration. These two IC audiophile are none I do not know, known to everybody; for so many years the rapid development of audio technology, but the two IC due to performance, superior sound quality, excellent, is still widely used, enduring. Lok Lam, a famous American audio manufacturers there to LM3886 to amplify the core of the expensive machines, it can be said that the LM3886 is one of the every audiophile will play and used to play audio amplifier IC.

Product Details

All parts of the products are original authentic, plain, pure quality; the use of high-quality original parts, not just the safety and quality are guaranteed, long service life and, more importantly, a strong guarantee to achieve the design goals is to make the actual performance. Pursuit of first-class quality Our aim has always been.

The design of this board is so special about using the jumper between the before and after class, making the volume potentiometer can be placed also be in the front input on the preamplifier, noise, distortion is smaller, better dynamic.

The entire circuit board layout of the traces are very strict and reasonable, the overall PCB traces point grounding mode. This amplifier board is stable and reliable output power; beautiful mellow sound, open sound field. Dimensional sense of strong, steady and solid and powerful low-frequency signal to noise ratio is very good, wide dynamic range; clear details, excellent transient response and play a variety of music rise to the occasion, a very good performance in the playback environment of the family.

The wiring of the board is very simple, as long as the minimal configuration of the parts can be assembled into an awesome stereo HIFI consolidated power amplifier, ideal for audio enthusiasts production use. Can also be more suitable according to their own understanding of the circuit put better parts, enjoy the fun of DIY process.
