Rotel RA-1592 MKII silver

Hi-Fi Integrated Amplifier: Rotel RA-1592 MKII

The Rotel RA-1592 MKII is a class AB stereo integrated amplifier offering remarkable output power. It delivers 200 W per channel at 8 Ω and 350 W at 4 ohms, with a total harmonic distortion of less than 0.008%. This generous power allows it to efficiently drive a wide range of speakers, even the most demanding models. The RA-1592 MKII particularly excels in reproducing low frequencies, offering a dynamic and controlled response that adds depth and impact to your music.

The amplifier uses a toroidal transformer manufactured in-house by Rotel, ensuring stable and robust power supply. This high-quality component contributes to the RA-1592 MKII’s exceptional sound performance, providing the necessary energy to faithfully reproduce the most complex and dynamic musical passages.

Versatile Connectivity for All Your Audio Sources

The RA-1592 MKII offers a comprehensive range of connection options to meet the needs of modern audiophiles. On the analog side, it features three RCA inputs, a balanced XLR input, and an MM phono input for turntables. For digital sources, the amplifier provides three coaxial and three optical inputs, all compatible with signals up to 24-bit/192 kHz.

The USB-B input allows direct connection to a computer and supports resolutions up to 32-bit/384 kHz PCM as well as MQA decoding and rendering. A front USB-A input is also available for connecting iOS devices. For wireless music, the RA-1592 MKII integrates Bluetooth with aptX and AAC codecs, ensuring high-quality transmission from your mobile devices.

A Quality DAC for Precise Digital-to-Analog Conversion

At the heart of the RA-1592 MKII’s digital section is a high-performance Texas Instruments digital-to-analog converter (DAC). This 32-bit/384 kHz DAC ensures precise conversion of digital signals to analog, preserving all the details and nuances of your high-resolution audio files. Rotel has optimized the DAC’s output circuits with twelve new coupling capacitors, enhancing frequency response and overall sound reproduction accuracy.

Significant Improvements

The RA-1592 MKII represents a notable evolution from its predecessor, with over 33 component changes in acoustic capacitors, filter capacitors, and power supply. These modifications have improved the overall sound quality, offering a wider and deeper soundstage, as well as better precision in instrument positioning.

Rotel has also made improvements to the preamplifier and power amplifier circuits, optimizing signal paths for even more faithful audio reproduction. These refinements contribute to the RA-1592 MKII’s ability to reveal the finest details of your favorite recordings while maintaining a natural and engaging musical presentation.

Practical Features for Everyday Use

The RA-1592 MKII offers several practical features to enhance the user experience. It includes tone controls for bass and treble, as well as balance, all accessible via the amplifier’s menu. A tone control bypass mode is also available for purists seeking the most direct signal path possible.

The amplifier allows you to set a maximum startup volume level and offers the option to configure a fixed gain for each input. An auto-off function can be activated to save energy when the device is not in use.

The RA-1592 MKII is Roon Tested certified, ensuring optimal compatibility with the Roon audio playback software. Although it does not have built-in network streaming capabilities, it can be easily paired with an external network player to access your favorite streaming services.

System Integration and Advanced Control

For complex audio-video installations, the RA-1592 MKII offers several control and integration options. It features an Ethernet connection for software updates and IP control, an RS232 port for integration with home automation systems, and 12V trigger connections for synchronization with other devices.

The Rotel Link function allows you to control multiple Rotel products with a single remote, while an input for an external infrared receiver provides additional flexibility for amplifier placement.
