Detailed Information:

LM4766 amplifier chip is introduced:
LM4766 and we are familiar with the LM1875/76 and LM3886, also is the national semiconductor company's products, but its class is far higher than these a few products. LM4766 is one double track power amplifier chip, each channel in load can be output 40 w average power, and distortion is less than 0.1%, LM4766 can do it in the human ear audible frequency band, 30 w power output under the circumstance of only 0.06% of distortion and noise value, this level for LM1875 speaking, even in 20 w under ideal power also can't do. So LM4766 kingdom in half power amplifier chip, is to "overture (overture)" series, is the most exclusive half countries single chip power amplifier module is one of 1875, 3886 and so on "big brother".
LM4766 in functional design also has distinguishing feature very much, this integrated block internal with perfect protection measures: overvoltage, undervoltage, overload, super temperature (165 temperature when output automatically shut off, 155 temperature automatically return to work) and the company patent - aso SPIKE peak protection (guarantee integrated amplifiers final pipe work in the characteristic curve of the safety work functions).
YX - 4766 fever amplifiers features:
A: fine, elegant chassis appearance design.
The chassis is the thickness of 4 mm aluminium chassis, the front panel for 6 mm thick aluminum plate, the plate to 3 mm thick aluminum plate, box front/rear board and the whole case overall are numerical control (nc) machining, then through fine grain drawing oxidation anode is handled and become, whole appears is exquisite, luster, GaoZhuang have grade.
B: high quality, safe and practical function Settings:
USB decoding play function:
This is also the research and development center and general 4766 power amplifier design different a characteristic. As now listening asks is ceaseless rise, now all the pursuit of the sound source is no longer stay in previous MP3 kind of audio formats, to instead of the APE is nondestructive format even higher audio file. Indeed, from the same song broadcast duration also yes song capacity perspective, the capacity of the MP3 format is only M, and APE format file size is M, visible, APE format content more rich, many details reflect more perfect. And before there are quite a part of the player can't support APE format play, or general now level of notebook computer directly from audio outlet connected to the amplifier effect also reflect very general.
This 4766 pa directly solved this problem, through her, can be directly connected to computers USB ports, without any additional drive can direct the high quality play APE format songs, simple, convenient, high grade.
And the USB decoding source and external input source the handoff is not close the reasonable automatic switching mode, when insert the USB port, signal channel to be automatic and amplifiers section connection is good, when pull out USB, signal and automatic and external input default on; Design is very reasonable and convenient, but also avoid the between mutual crosstalk.
Startup delay. Output short circuit protection. Shutdown flash fault circuit design.
This machine independent set the startup delay protection circuit, power amplifier in the boot can delay 5-10 seconds of time delay on and avoided the boot on a speaker's current impact, at the same time in circuit abnormal have direct output, the circuit will be timely detection and cut off the output, effective protection of your speakers; In shutdown, can instantly cutting output, and never sloppy.
The selection of fever device with:
Resistor: using 1% high precision 1/4 w metal film resistor, or so channel more balance, sound field location more accurate.
The volume potentiometer selection table production type A 100 k step by step potentiometer, feel is good, contact sex more stable.
Coupling capacitance at cost choose the United States ERSE polypropylene capacitor 2.2 uf / 250 v audio special coupling gourmet capacitance, this also is a good sound the key.
Power supply transformer for long history and were known at home and abroad sichuan hengda high quality ring transformer.
YX - 4766 of the power amplifier timbre features:
4766 warm voice, downy, to listen to more easily, feedback blocking condenser volume to leave a bit bigger, convenient change a sound
