Rotel RC-1572 MKII silver

Presentation of the Rotel RC-1572 MKII Stereo Preamplifier

The Rotel RC-1572 MKII is a stereo preamplifier designed with meticulous attention to detail. It incorporates technological advancements and improvements over the previous version. Its low-noise power supply includes an internally manufactured toroidal transformer, which helps reduce stray emissions. This power supply feeds a bank of low ESR capacitors, ensuring stable current for sensitive circuits, contributing to reduced noise and distortion.

Elegant and Functional Design

The RC-1572 MKII features an elegant silver-finished chassis that will seamlessly integrate into your hi-fi system. Its sleek front panel includes an easy-to-read white LED display on a black background, as well as convenient headphone jack and USB port. The buttons allow intuitive navigation through menus and settings, but a full remote control is also provided for complete remote operation.

High-End Digital-to-Analog Converter

The digital heart of the RC-1572 MKII is based on a premium Texas Instruments 32-bit / 384 kHz DAC. It is supported by custom external output filters that deliver digital sources with exceptional dynamics and rich musicality. This DAC is Roon Tested certified and supports high-resolution MQA and MQA Studio formats.

Comprehensive and Versatile Connectivity

In terms of connectivity, the RC-1572 MKII leaves nothing to chance. It features RCA and XLR analog inputs, an MM phono input for turntables, coaxial and optical digital inputs, as well as an asynchronous USB-B port for playback from a computer. Bluetooth aptX and AAC are also included for wireless connection to your mobile devices. The RCA, XLR, and subwoofer outputs offer great installation flexibility.

Practical and Customizable Settings

Easy to use on a daily basis, the RC-1572 MKII offers automatic on/off functions, signal detection, fixed volume setting, and bass and treble adjustment. Software updates can be performed via the Ethernet and RS232 ports. Everything is designed for an optimal and customizable user experience.

Pure and Immersive Sound

Thanks to all these refinements, the RC-1572 MKII delivers sound with striking purity and realism. The soundstage is wide and detailed, reproducing every nuance with precision and musicality. Whether you’re listening to CDs, vinyl, or high-resolution files, this preamplifier will make your hi-fi system shine and immerse you in your favorite music.

Can this preamplifier directly drive a pair of speakers?

No, the RC-1572 MKII is a preamplifier. It must be paired with a power amplifier, such as the Rotel RB-1582 MKII, to drive speakers. The preamp handles source selection and volume control, while the power amp provides the necessary power to the speakers.

Can I connect an active subwoofer to the RC-1572 MKII?

Yes, this preamplifier has a dedicated subwoofer output. You can easily integrate an active subwoofer into your system to enhance the bass. The subwoofer level adjustment will be done directly on the subwoofer.

Is the Bluetooth quality good on this model?

Absolutely. The RC-1572 MKII is equipped with aptX and AAC Bluetooth, codecs that offer excellent audio quality, significantly superior to standard SBC Bluetooth. With a compatible smartphone or tablet, you’ll enjoy sound reproduction close to that of a wired connection.
