Unison Research Unico 90 User Manual

8
TECHNICAL SPECIFICATIONS
Output power: 100+100 W RMS su 8Ω
180+180 W RMS su 4Ω
Frequency response: -1dB @ 12Hz e 45kHz, -3 dB @ 6Hz e 80 kHz
Input impedance: 21kΩ //300pF
Input sensitivity: 860mV RMS
Input stage: Pure A class, double triode totem pole ECC83 and
parallel totem pole ECC81
This single stage due to the particular circuitry is able to
amplify the input signal
and drive directly the power stage..
Output stage: Class AB thermostable, complementary Hexfet (3 pairs
for channel)
Number of stage 2, This amplifier due to the particular circuitry is
realized by only two stages:
input stage and output stage, and use only local
feedback
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
THD: < 0.15% @ 1kHz, 1 W
< 0.50% @ 1kHz, 10 W
Output resistance: <0.4 ohm, resistive on all audio frequencies
Power Consumption: 550 W (at max power on 8 ohm)
Dimensions: 43.5cm x 18 cm x 44 cm
Net weight: 20 kg
