Reference beyerdynamic A2 original circuit design, combined with their own ideas designers redesigned and improved A2-PRO Professional Headphone Amplifier.
Using the integrated design
Dual headphone output jack, compatible with high impedance and low impedance headphones, Suitable for 10-600 ohm impedance range, Can connect two headphones at the same time
Front panel switches use the excellent brand in Taiwan, feel very good, and reliability
Integration of the EMI filter, better dual-capacitor filter effect
Use Nippon takamisawa dedicated signal relay
Regulators used LM317,337
The rear panel Match 1 set audio input and 1 set audio output
Symmetrical design, optimize go line, USES the star grounding, achieve zero noise, good separating degree
PCB type power socket, the built-in EMI filter, and USES the philips capacitance
Multi-level parallel filtering, and decoupling, effectively filter high frequency interference and noise
WIMA parallel diode
Use ALPS potentiometer
1 set of audio input RCA, one set of audio output RCA
Note: There is no USB input by default. If you need the USB input version, please contact us!
