Усилители мощности → A-65
As a model-change successor to the A-60, the new A-65 incorporates accumulated Accuphase know-how while featuring a number of further improvements. The input stage is configured as an instrumentation amplifier to allow fully balanced input signal paths. The output stage of the A-65 features power MOS-FETs renowned for their excellent sound and superior reliability. For each channel, ten of these devices are arranged in a parallel push-pull arrangement. MOS-FETs have excellent frequency characteristics, and their high input impedance reduces the load imposed on the preceding drive stage.
- Pure Class A operation delivers quality power: 60 watts ×2 into 8 ohms
- Power MOS-FET output stage features 10-parallel push-pull configuration and delivers linear high power progression to ultra-low 1-ohm impedances
- Input section configured as instrumentation amplifier
- Further improved MCS+ circuit in amplifier section
- Current feedback topology combines stable operation with outstanding sound
- Bridged mode allows upgrading to monophonic amplifier
- Two selectable meter types: digital power meters showing true power values and bar graph indicators
