UNISON RESEARCH UNICO 90 HYBRID STEREO INTEGRATED AMPLIFIER

The heart of the Unico 90 circuit is found in its hybrid structure. All of the gain, and subsequently the “character” of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.

• Output power: 100+100 W  RMS on 8Ω / 160+160 W  RMS on 4Ω
• Valves: 2X ECC83, 4X ECC81
• Output stage: Class AB thermostable, 6X Hexfet
• 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.
• 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 RCA, 2 XLR, 1 “bypass” RCA)
• Line Outputs: 1 tape, 1 sub  (volume controlled)
• Frequency response: -1dB @ 12Hz e 45kHz -3 dB
• Input impedance: 21Kohm // 300pF
• Input sensitivity: 860mV RMS
• Output connectors: 4 + 4  bi-wiring
• Global Feedback factor: 0 dB
• THD: < 0.15% @ 1kHz, 1 W < 0.5% @ 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 44 cm x 18 cm h
• Net weight: 20 kg

We try and keep on top of our pricing, but it's a mammoth task for one person. So, if you see this product offered cheaper elsewhere, or you are offered it for less elsewhere (proof will be required) and you feel like supporting an extremely independent retailer, do get in touch and we will do our very best to match or beat wherever we can. We can't promise to do so, as there may some extenuating circumstances where we just wouldn't be able to, but we'll always do what we can.

Needs to be like for like - new for new, ex-demo for ex-demo, same colour and specs etc.
