RA-1572 MKII Integrated Amplifier

The RA-1572MKII Integrated Amplifier is an essential component for music lovers leveraging the best of Rotel’s analog and digital technologies bringing music to life with exceptional fidelity. 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.

As typical of Rotel amplifiers, the RA-1572MKII 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 RA-1572MKII support digital sources utilising a Texas Instruments 32-bit/384kHz DAC with critically tuned output filter circuits rendering even the most subtle detail. The preamplifier circuits and linear amplifier gain stages have been custom engineered ensuring natural detail, agility and an immersive soundstage. Analogue, digital, PC-USB supporting MQA, aptX™ and AAC wireless Bluetooth streaming, XLR Balanced and Moving Magnet Phono stage inputs ensures connection to your favourite sources.

The RA-1572MKII is certified Roon Tested delivering the best experience using Roon software so you can just enjoy the music.

The front panel includes a status display, source and volume controls, Speaker A-B selection for Zone 2, and 3.5mm headphone jack. Ethernet and RS232 connections allow seamless integration with control systems and software updates.
