BRAND NEW....KingRex just released its new class A two-box Headquarter headphone amplifier with pre-amp outputs . Instock NOW!
Input impedance is 15K, output impedance 1.8 ohms. Gain is 18.5dB, power ouptut variable with headphone impedance - 100mW are produced at 300 ohms, 170mW at 150 ohms, 360mW at 60 ohms and 570mW at 30 ohms. THD+N is given as 0.005% under full 2Vrms output. Dynamic range is 110dB. The 6.35mm headphone jack is a Neutrik with gold-plated contacts. The external power supply consumes less than 10 watts to make it a green product. The power supply is a linear type with a 48VA toroidal transformer. It uses 8 Nippon Chemicon capacitors for a total 25,100uF storage capacitance plus there are 5 x 2,200uF units at the AC input and 3 x 4,700uF units for the filtered DC output. Voltage acceptance is +/-10% of the rated 110/220V versions.
