Rotel Introduces RA-1592 Integrated Amplifier Rotel Electronics has introduced its RA-1592 stereo integrated amplifier built on Rotel RC-1590 preamplifier and RB-1582mk2 power amplifier in a single chassis design.By RS Staff Published: May 20, 2016 ⋅ Updated: April 15, 2019 Rotel Electronics has introduced its RA-1592 stereo integrated amplifier built on Rotel RC-1590 preamplifier and RB-1582mk2 power amplifier in a single chassis design. The RA-1592 has a classic Class AB design with 200 watts per channel into eight ohms, and features a rugged power supply with a large toroidal transformer, coupled to select T-network, slit-foil capacitors. The result is a power supply designed to resist sag and distortion under complex speaker loads or dynamic signal transients. The high performance preamplifier section incorporates a 32bit 768KHz AKM digital-to-analog converter and analog stages. The DAC and surrounding circuitry supports a vast array of source inputs including DSD capable PC-USB (24bit/192k), three coaxial, three optical, integrated aptX Bluetooth and a front mounted USB iPod input. For analog listeners, there is a phono stage input (MM), XLR balanced input, and three analog RCA source inputs. User selectable A-B speaker outputs with five-way binding posts, RCA pre-output and dual subwoofer outputs provide the ultimate flexibility in installation. The amplifier protection circuits monitor DC offset, overcurrent, short circuit and temperature to protect both the electronics and attached speakers. Custom integration features include RS232 and Ethernet IP control, 2 trigger outputs, remote IR input and automated digital signal sense power control for easy integration with streaming sources and control systems.
