Product Description :

This headphone amplifier uses the Lehman architecture and is the final upgraded version of the high-end version. The components are all made of fever materials, followed by a lot of optimizations in the circuit layout! As shown in the figure, the headphone amplifier rectification part uses Philips passivation diode, the speed is fast, the main filter circuit uses a fever gold capacitor, the voltage regulator tube uses the US ON, the consistency is very good, and the good power part is the power guarantee. The gold-plated signal holder with fully enclosed potentiometer will greatly improve the service life and good sound quality without loss of transmission. The patch 5532 is used as the preamplifier part, which is very musical (such as mind can be replaced by in-line). All resistors use five-color ring for high precision. Thick copper foot resistance. The film capacitor is used with Red Weimar and Siemens, and the in-line capacitor uses a fever capacitor. The film capacitor is placed close to the op amp to ensure the shortest transmission distance. The power amplification part uses the Lehman royal tube, and the tube pair is paired with the tiger fisher's transistor DC parameter tester. Ensure the consistency of the pipe. The headphone amplifier has comprehensive protection to protect our expensive headphones at critical times, with ±0.9 volts on DC protection. The headset will be turned on after about three seconds of power on, ensuring that there is no impact when starting up. The output is cut off immediately when the machine is turned off, and there is no impact on the machine. The sound is tri-band balanced, the bass dive is very deep, the medium frequency is mellow, and the treble is beautiful! The revised circuit is widened to the 7HZ amplification factor in the low frequency range, and the frequency response range is 1HZ--100KHZ. Does not contain power. The power supply uses AC 15 volts (AC12~17V). The amp power is up to 800mW, which can perfectly push high-impedance big ears such as K701, HD650, DT880/990. The size of the chassis is about: 97mm wide / 32mm high / 128mm deep (the front knob and rear socket are not included).
