Type 47 amp circuit is a classic circuit with 2 Output Op Amp to AMP, which can reduce the current distortion to improve power supply amp. But this is still insufficient, a dual op amp up to provide 100MA current, so to some high 1 points of the headset is completely inadequate, I re design of the E47 amp uses a voltage amplifier alone, and 4 op amp parallel output, so the output current is greater than 200MA. and the negative feedback structure, dynamic. Detail even better.

Following a machine of highlights, these objects are not those who rely on advertising that better than 3-400 amp amp with:
1 double the performance of the structure of the type of 47, no big loop feedback, the dynamic details of the headset is better.
2 with Japan’s OMRON headset protection circuit, this is very critical, desktop with headset relay protection, portable headset with relays, 500 yuan in no 2, no relay amp, if the machine has a problem, it is necessary to amp will die, some function!!!
3 with excellent architecture and high quality battery, although more op 1 times, life more than 6 hours, much higher than the level of the two longer
4 Aluminum Alloy chassis, although the market is the most Aluminum Alloy amp, but the appearance of our fine degree is completely different, ergonomic design, portable operation knob is not exposed, more assured
5 high precision ALPS default configuration of Japan, lower left and right channel error
6 the use of the export of foreign Foxconn’s shielded headphone jack, the volume is still not the maximum noise
