Special stabilizer and speed regulator so-called “Inverter”. It is a speed controller and stabilizer for AC motors used in Nottigham Analogue turntables. It is an option intended for people who want to maximally improve the sound quality.
The audible benefits of using an inverter are very clear. Details, dynamics and soundstage are much better, but perhaps the most obvious feature is how the whole tempo and rhythm of music resounds while maintaining naturalness. The rotation stability is impeccable, regardless of the quality and parameters of the power supply.
All Nottingham Analogue turntables can be powered using this dedicated inverter.
