A powerful, versatile integrated amplifier
Rotel's RA-1592 MkII builds off of the legacy of its excellent predecessor, the RA-1592. It delivers a whopping 200 watts to drive one or two pairs of speakers. And the power is clean and robust, thanks in part to a custom-designed toroidal transformer. You get system-building versatility, too. There are plenty of inputs for connecting sources, and built-in Bluetooth for convenient music streaming. It's a solid centerpiece for an impressive Rotel sound system.
Here's what's different: The MkII features a premium Texas Instruments 32-bit/384kHz DAC that converts incoming digital signals to analog with precision and clarity. And it can now decode audiophile-quality MQA and MQA Studio files. Improvements to the power supply and amplifier gain stages further refine this model's already remarkable performance.
The RA-1592 MkII offers an array of analog and digital inputs. There are four analog RCA inputs on the back panel, including a phono stage for connecting a turntable with a moving magnet cartridge. And the balanced XLR input helps you get the best possible sound with a compatible source component, like Rotel's matching RCD-1572 CD player.
The integrated amp's premium digital-to-analog converter ensures clear, precise sound from all your digital sources. There are three optical and coaxial inputs apiece, plus a rear-panel USB Type-B port for connecting a PC (Note: On the MkII, this port is not compatible with DSD files). A USB Type-A port on the front panel that handles audio signals from an iPod®, iPhone®, or iPad®.
And there are a wealth of control options, including an IR input, RS-232 port, and dual 12-volt trigger outputs. A proprietary 3.5mm Rotel Link input/output allows connected Rotel products to communicate with each other and be controlled via the Rotel app. An Ethernet port lets you connect the amplifier to your home network for software updates and integration with third-party control systems.
Rotel has been crafting high-performance gear for music and home theater enthusiasts since 1961. They focus on creating the best signal path possible, using premium capacitors, transistors, diode bridges, and custom toroidal power supplies to get the most from music and movie soundtracks. Crutchfield is proud to offer a diverse selection of Rotel components including preamps, amplifiers, CD players, and home theater processors.

Robust Class AB 2-Channel Amplifier: The RA-1592 MKII integrated amplifier leverages the strengths of Rotel's award winning RA-1592 MKII preamplifier and RB-1582 MKII power amplifier in a sleek single chassis design. With a powerful 200 watt x 2 channel Class AB amplifier using performance audio grade components, the RA-1592 MKII can effortlessly drive large speaker systems. The impressive Rotel manufactured toroidal transformer is a key element in the power supply design which also includes custom slit-foil storage capacitors and a dual-monoblock topology. All of this helps to ensure the amplifier performance stands up to even the most complex music and real world playback conditions.
- The RA-1592 MKII's power output is rated at 200 watts per channel into 8 ohms with all channels driven. Rotel has chosen to specify the power output in this way because, in Rotel's experience, it gives the truest value of the receiver or amplifier's power capability.
- When comparing specifications for different amplifiers, you should be aware that power output is often specified in other ways, so you may not be comparing "apples-to-apples". For example, the power output may be quoted with only one channel or two channels driven (not all channels), giving a higher maximum figure.
- Be aware that the RA-1592 MKII is capable of high power levels, in excess of 200 watts respectively per channel. Make sure that your speakers can handle the power of the amplifier. If in doubt about your speakers, ask your Crutchfield advisor.
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. Further, Rotel's Class AB amplifiers don’t use output inductors because they decrease control and, consequently, sound quality.
- 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: As typical of Rotel amplifiers, the RA-1592 MKII integrated amplifier draws on a high capacity power supply based on a Rotel custom designed and in-house manufactured oversized toroidal transformer. This low impedance power supply has ample power reserves, which enables the RA-1592 MKII to easily reproduce the most demanding audio signals. 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.
Symmetrical Circuit Traces: The integrated amplifier'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.
Texas Instruments (TI) 32-bit/384kHz DAC: In recognition of the predominance of digital sources available today, the RA-1592 MKII has a built-in state of the art 32-bit/384kHz Texas Instruments digital-to-analog converter (DAC). The onboard TI 32-bit/384kHz DAC has been optimized to retain your music's full dynamic with precisely tuned output filter circuits that deliver unprecedented acoustic detail, wide sound stage and exact positioning.
MQA (Master Quality Authenticated): MQA (Master Quality Authenticated) is a revolutionary end-to-end technology that captures and delivers master quality audio in a file that's small enough to download and stream. MQA ensures the your will hear your favorite digital audio music soundtracks exactly the way the artist intended you to hear it when it was approved in the studio. Support for MQA requires USB Audio Class 2.0 via USB-B. USB Audio Class 2.0 requires installation of the Windows PC driver on the included USB thumbdrive. MAC computers do not require a driver to support PC-USB Audio Class 1.0 or 2.0.
Roon Tested: The RA-1592 MKII is certified as Roon Tested and compatible with software via the integrated amp's USB-B port when connected to a compatible Windows or Mac computer. Being Roon Tested means that Rotel and Roon have collaborated to ensure you have the best experience using Roon software and the RA-1592 MKII together, so you can just enjoy the music. For the best user experience it is suggested to use USB Audio Class 2.0 when using Roon. USB Audio Class 2.0 requires installation of the Windows PC driver on the included USB thumbdrive. MAC computers do not require a driver to support PC-USB Audio Class 1.0 or 2.0.
Protection Circuitry: The integrated amp has both thermal and over-current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions. The protection circuits are independent of the audio signal and have no impact on sonic performance. Instead, the protection circuits monitor the temperature of the output devices and shut down the amplifier if temperatures exceed safe limits.
Note: In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage.
Mounting & Placement Options: The Rotel RA-1592 MKII integrated amp can simply be tabletop mounted (no rack-mount hardware available).
- The RA-1592 MKII generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be open. There should be at least 4" of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating.
- Make sure that the shelf or cabinet can support the weight of the amplifier. The amplifier should be installed in or on furniture designed specifically for 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.
Note: The RA-1592 MKII's heatsinks provide adequate cooling for most installations. However, when installing the amplifier in a confined space or near other heat-generating components, additional cooling may be desirable. See Accessories Tab for cooling fan options (sold separately).
Balanced & Unbalanced Analog Inputs: The Rotel RA-1592 MKII integrated amplifier is outfitted with a total of four line-level analog inputs; there is one balanced XLR stereo analog audio input and three unbalanced stereo RCA analog audio inputs. Balanced XLR connections guard against induced noise and allow long cable runs without compromising sound quality.
