About Lehmann architecture circuit
This product is a reference from the Lehmann circuit amp, Lehmann amp was known as the Sennheiser HD650 best partner in the game player. Amp with headset signal output two 6.35 mm diameter interface, with Lehmann in 300 ohm when using the headset the output power is 200mW, the output power can reach 400mW with 60 ohm impedance of the headset is used, and the frequency range between 10Hz-35kHz and bipolar ratio can reach more than 95dB, the outstanding performance of the sound quality have been the consistent high praise
