The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – have developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage). Output power: 150+150 W RMS at 8 / 220+220 W RMS at 4 Frequency response: -1dB @ 12Hz & 45kHz, -3 dB @ 6Hz & 80 kHz Input impedance: 24k // 100pF Input sensitivity: 860mV RMS Input stage: Pure A class, double triode totem pole ECC83 Driver stage Pure A class, double triode totem pole 6H30 Output stage: Class AB thermostable, complementary Hexfet (4 pairs for channel) Input: 6 line (3 unbalanced, 2 balanced, 1 bypass unbalanced) Line Outputs: 1 tape, 1 sub (volume controlled) Output connectors: 4 + 4 bi-wiring Global Feedback factor: 0 dB Local Feedback factor: 16 dB THD:
