Features

Stereo Preamplifier: The RC-1572 is a full featured, high performance, stereo preamplifier that has been optimized to retain the full dynamic range and subtle nuances of your music. The RC-1572 stereo preamplifier leverages the design of Rotel's flagship RC-1590 preamplifier including its 32 bit/768kHz AKM stereo DAC to handle critical signal conversion. Premium circuit components have been selected only after extensive listening evaluations. Careful routing of all low level signals has been practiced to ensure impressive signal to noise levels. The result is effortless musical dynamics, impressive detail and scale. A large toroidal transformer and regulated power supply ensures stable current and voltage requirements to all stages under dynamic conditions. Both analog and digital sources have been given equal consideration as today’s listener often has several digital sources, but may also enjoy legacy formats like vinyl LPs. The RC-1572 utilizes relay switching for analog sources instead of an IC based switch to maintain the integrity of the signal path for RCA, phono and XLR inputs.

Balanced Design Concept: Balanced Design Concept is the essential Rotel design philosophy that revolves around three major areas - Parts selection, circuit topology, and critical evaluation. These aspects influence final sound quality significantly and illustrate the holistic Balanced Design Concept approach to Rotel's product development. Thanks to the Balanced Design Concept, Rotel components easily exceed the performance of many mass produced audio products that offer plenty of features but skimp on audio quality, and compare favorably to components that are many times the price. Rotel continues its pursuit of extraordinary audio performance, which elevates the home entertainment experience through their core values of sonic accuracy, reliability, and affordability.

  • Parts Selection: Rotel engineers select premium capacitors which provide better performance across both power and frequency spectrums to produce a more accurate and musical reproduction of the audio signal. High quality power supply capacitors provide a more efficient transfer of energy with fast charging and discharge time to ensure the circuits have the reserve power when needed. At each stage of development, Rotel engineers listen to circuit prototypes and revise the design when they feel they can gain a sonic advantage by using a particular component from another manufacturer or by specifying tighter tolerances. Since Rotel is an independent manufacturer, they are free to source parts from highly respected suppliers around the world to fit their requirements.
  • Circuit Topology: It’s not enough to simply use good parts. Where you put them is equally if not more important. That's why Rotel keeps their circuit paths as short as possible, so there's less chance that spurious emissions and unwanted leakages will corrupt delicate signal nuances. That's also why Rotel often uses more expensive "on-board" relay source switching, rather than routing a signal from a rear-panel input to a front-panel control. Rotel also relies heavily on something called Symmetrical Signal Trace design. This keeps each channel's signal path identical to the others to preserve the imaging and soundstage. Rotel also uses electrically superior "star" grounding techniques to improve performance because star grounding routes all ground connections to a single point to reduce potential loops that might introduce noise or produce hum.
  • Critical Evaluation: Rotel's development team places a lot of importance on critical listening sessions before the final product is sent to market. Rotel electronic and acoustic engineers, both in the UK and Asia, have honed their aural acuity over the course of decades of collective experience to evaluate each stage of product development from working samples, through pre-production and, finally, to verify that final production is the same as the pre-production units. Some sessions evaluate different circuit elements: capacitors, resistors, and active devices such as transistors or operational amplifiers. Others focus on differences in circuit layouts or differences caused by power supply elements. Only after this tuning process is complete with sonic performance confirmed will the product be launched to the market. 

Custom Designed Toroidal Transformer: The RC-1572 stereo preamplifier has a highly regulated power supply incorporating Rotel's custom-designed toroidal power transformer. This low impedance power supply has ample power reserves, which enables the amplifier to easily reproduce the most demanding audio signals. Rotel manufactures its own toroidal transformers in-house to high tolerances using raw materials selected from proven, trusted suppliers. The result is a rugged power supply that won't easily distort the music under dynamic conditions.

Symmetrical Circuit Traces: The preamplifier's printed circuit boards (PCB) are designed with Symmetrical Circuit Traces. This ensures that the precise timing of the music is maintained and faithfully recreated. The circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been examined to ensure the most faithful music reproduction.

AKM 32-bit/768kHz DAC: The Rotel RC-1572 stereo preamplifier features an onboard AKM 32-bit/768kHz DAC (digital-to-analog converter) that has been optimized to retain the full dynamics, detail and subtle nuances of your Hi-Res music collection -  rendering a musical performance exactly as the artist intended.

Mounting & Placement Options: Rotel recommends installing the RC-1572 stereo preamplifier in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your Crutchfield Advisor for advice about component furniture and proper installation of audio components.

Note: The Rotel RC-1572 stereo preamplifier does not support rack-mounting.

Connections

Balanced & Unbalanced Analog Connectivity: The Rotel RC-1572 stereo preamplifier is outfitted with balanced XLR and unbalanced RCA inputs and outputs. Balanced XLR connections guard against induced noise and allow long cable runs without compromising sound quality.

  • XLR & RCA Inputs: The Rotel RC-1572 is equipped with one balanced stereo XLR analog audio input and four unbalanced stereo RCA analog audio inputs (including a MM Phono input) for connecting multiple source components. You should choose only one method of analog connection from a source component to the RC-1572 stereo preamplifier. Do not connect both the RCA and XLR outputs of a source component to the RC-1572 at the same time.
  • XLR & RCA Outputs: The RC-1572 features a balanced stereo XLR analog audio preamp output and an unbalanced stereo RCA analog audio preamp output for connecting an external amplifier(s). Do not connect both the XLR and RCA preouts to the amplifier at the same time. Changes to the settings of the Volume, Balance, & Tone controls will affect the signal from the XLR and RCA preamp outputs.

MM Phono Input: There is one Phono input which supports the connection of a turntable with a MM (moving magnet) cartridge. There is also a ground terminal for the Phono input to prevent hum and noise.

Digital Audio Inputs: The RC-1572 is equipped with a total of four digital audio inputs; including two optical (toslink) digital inputs and two coaxial (RCA) digital inputs. All four digital inputs will support 2ch stereo PCM audio up to 24-bit/192kHz.

Note: The digital audio inputs do not support Dolby Digital, DTS, and other multichannel audio formats.
