Features and Specifications
LM4766 digital amplifier/USB HIFI Audio Decoder
Features:
This case is all aluminum chassis with 4mm thickness. The front panel is 6mm thickness aluminum material panel , and the back panel is 3mm thickness aluminum plate. The front/back panel of the case and the whole case are CNC processed, and then processed by oxidation anodizing. The overall appearance is fine, shiny, and high quality.
USB decoder playing function:
This 4766 power amplifier can be directly connect to the USB port of the computer. You can directly play songs in APE format without any additional driver. It is simple, convenient and high-grade.
Moreover, the switching mode between the USB decoding audio source and the external input audio source is automatic switching . When the USB port is inserted, the signal channel is automatically connected with the power amplifier. When the USB port is unplugged, the signal is automatically connected with the external input by default; The design is very reasonable and convenient, and the mutual interference between these two is avoided.
Startup delay, output short circuit protection, shutdown flash circuit design:
The machine is independently equipped with a power on delay protection circuit, which enables the power amplifier to be connected with a time delay of 5-10 seconds when starting up, avoiding the current impact on the speaker when starting up. At the same time, when the circuit is abnormal and there is a direct output, the circuit will detect and cut off the output in time, effectively protecting your speaker; When the machine is turned off, the output can be cut off instantly.
*Parts:
Resistance: 1% high-precision 1/4W metal film resistance is adopted, which makes the left and right channels more balanced and the sound field positioning more accurate.
The volume potentiometer is Taiwanese made type A 100K stepping potentiometer, which has a good feel and more stable contact.
The American ERSE polypropylene capacitor 2.2uf/250V capacitor is used as the coupling capacitor .
The power transformer is a high-quality core transformer.
