Description
Rotel RA-1572 MKII Integrated Amplifier
The Rotel RA-1572 MKII Integrated Amplifier utilises an in-house manufactured oversized toroidal transformer. The toroidal transformer’s shape helps prevent stray radiation patterns from corrupting audio signals as they pass through adjacent circuits. The transformer feeds a bank of 4 low ESR, high efficiency, T-Network slit-foil storage capacitors for deep, controlled bass energy.
The role of an integrated amplifier continues to evolve with the RA-1572MKII optimised in every aspect including the power amplifier delivering 120 Watts of robust Class AB output into 8 ohms, audio circuit design innovations, premium audiophile Digital to Analog Converter and a full complement of source inputs.
