DETAIL :
A1000 is a headphone amplifier with the external power to supply,although it has a small and exquisite size,its power output is very strong.In order to drive the headphone,the efficient swtiching power is used to be converted into the positive and negative power to supply the OPAMP and the eight transistors whose output current can reach 800ma. The circuit structure:OPA2134 and BC337/338*4. A1000 uses the universal high-quality external power supply which is AC 90V-270V, 50/60HZ. The whole circuit uses the high-precision components with famous brands,QC is necessary before production,each of the components must be tested to achieve high performance index and adjusted by YuLong senior audio engineers before use. All the machines must be passed through the 24-hour reinforcing experiment and examined by the dScope Series III digital audio analyzer critically.From production to voice adjusting to technical indicators and the stability of the machine,these procedures can guarantee the consistency of high quality. The style of voice: clear and bright,elaborate and soft,natural and endurable,the whole frequency is equivalent, high frequency power supply can ensure enough power of the headphone output,low noise,fine transient response.Technical Specification:
