Rotel RA-1572 User Manual
INTEGRATED AMPLIFIER
RA-1572
2 x 120 Watts
of robust Class
AB power
Long recognized as a central component in superb yet costeective music systems, the integrated amplifier’s 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-1572’s 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 transformer’s 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-1572’s 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

with aptX
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-o” 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 Rotel’s tradition of providing
extraordinary value. A mono subwoofer output is also provided.
User conveniences include two 12-volt triggers to control on/o
operation of other components, a highly visible VFD display for setup, internet-based soware updates, as well as RS232 and IP control
capabilities.
