Rotel RA-1572 Integrated Amplifier MKII

DESCRIPTION

RA-1572

The RA-1572 combines proven analog design with sophisticated digital circuits to bring all of your sources to life with amazing fidelity.

Long recognized as a central component in superb yet cost-effective music systems, the integrated amplifiers job has evolved substantially as many music-lovers have migrated to digital sources. The RA-1572 is one of the best examples of melding classic analog design with contemporary digital circuits to bring all of your sources to life with surpassing fidelity.

As typical of Rotel amplifiers, the RA-1572s circuitry draws on a high capacity power supply based on a Rotel custom designed and in-house manufactured oversized toroidal transformer. In addition to providing an abundance of voltage and current for all operating stages, the transformers toroidal shape helps prevent stray radiation patterns from corrupting audio signals as they pass through adjacent circuit stages.

Subsequent power supply segments built with tight-tolerance parts including T-Network capacitors provide the exact voltage and current requirements to ensure stress-free signal reproduction.

The RA-1572s input section is substantially more flexible than that found in most integrated amplifiers. In recognition of the predominance of digital sources available today, the RA-1572 has a built-in state of the art 32-bit/768kHz AKM digital-to-analog converter (DAC) and analog stages of the highest quality. The DAC and surrounding circuitry supports a vast array of source inputs including DSD capable PC-USB (32-bit/384kHz). A front panel USB input is provided for easy connection of a wide variety of music storage devices including Apple iPods, iPhones, and iPads. The Bluetooth input supports aptX for superior performance with compatible devices. In addition, two each coaxial (RCA) and optical (TOSlink) inputs provide easy connections for LPCM music sources including popular streaming devices with up to 24-bit word lengths sampled at 192 kHz. Importantly, it is possible to fix the level and set an auto-on option with digital inputs for use with devices that provide their own volume control for convenient hands-off use. Analog inputs include a pair of balanced XLR connectors in addition to conventional RCA jacks.

The Class AB output stage uses discrete devices to ensure precise reproduction of all signals regardless of origin with virtually any loudspeaker. The power output, conservatively rated at a robust 120 watts per channel into 8 ohms, is substantial as it is a continuous both channels driven simultaneously rating fully in keeping with real-world requirements and Rotels tradition of providing extraordinary value. A mono subwoofer output is also provided.

User conveniences include two 12-volt triggers to control on/off operation of other components, a highly visible VFD display for set-up, internet-based software updates, as well as RS232 and IP control capabilities.
