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). Tech specs Output power: 150+150 W on 8Ω / 250+250 W on 4Ω Valves: 2 x ECC83 2X 6H30 Output stage: Class AB thermostable, 8X Hexfet Input stage: Pure A class, double triode totem pole ECC83 Driver stage Pure A class, double triode totem pole 6H30 Input: 6 line (3 unbalanced, 2 balanced, 1 “bypass” unbalanced) Line Outputs: 1 tape, 1 sub (volume controlled) Frequency response: -1dB @ 12Hz & 45kHz, -3 dB @ 6Hz & 80 kHz Input impedance: 24kΩ // 100pF Input sensitivity: 860mV RMS Output connectors: 4 + 4 bi-wiring Global Feedback factor: 0 dB Local Feedback factor: 16 dB THD: < 0.005% @ 1kHz, 1 W < 0.002% @ 1kHz, 10 W < 0.003% @ 1kHz, 100 W < 0.002% da 20 a 20000 Hz, 150 W Output resistance: <0.4Ω, resistive on all audio frequencies Power Consumption: 550 W (at max power on 8 ohm) Dimensions: 43.5 cm x 18 cm x 44 cm Net weight: 25 kg
