It’s all about control. 
The RC-1590 stereo preamplier has been engineered 
to the highest audio performance levels and provides 
an incredible level of control and exibility for the 
user. Starting with a high performance power 
supply consisting of two Rotel custom built toroidal 
transformers for maximum efciency and low magnetic 
elds, these transformers provide low-noise isolation 
between the analog and digital signals. They are part of 
a reference-grade power supply consisting of individual 
analog and digital regulator circuits with custom-made 
slit-foil capacitors. Slit-foil capacitors have very quick 
charge/discharge times and low signal loss ensuring 
tight bass performance. 
Rotel engineers wanted to create a reference quality 
stereo preamplier to match with our new RB-1590 
stereo power amplier. Every aspect of component 
selection and circuit topography was designed and 
carefully evaluated during multiple listening sessions 
to ensure the highest delity. For example, analog and 
digital circuits were designed separately, by specialized 
Rotel teams. Analog inputs are all very low noise 
circuitry and include a high performance moving magnet 
phono stage. Digital inputs are fully isolated and feature 
a precision 32bit 768KHz Digital to Analog Converter 
(DAC). 
The RC-1590 is fully feature-laden with Balanced XLR 
and Unbalanced RCA inputs and outputs, a TI precision 
volume control IC, a xed volume line output, dual mono 
subwoofer outputs, digital outputs (Coax and Optical), 
digital inputs (3 Coax and 3 Optical), Aux, CD, and 
Tuner analog inputs, Internal APTX Bluetooth (supports 
APTX and standard Bluetooth) with rear mounted 
external antenna, a front USB iPod with 2.1A charging 
input, and rear panel PC-USB 24bit 192KHz input 
supporting DSD (Windows) and DoP (MAC computers 
DSD over PCM).
Other essential features include a remote control, 
2 x 12-volt trigger outputs, a dimmable display, an 
automatic power off function (congurable), RS232 and 
IP control for automation system integration, Internet 
based software updates, Rotel Link connection, a 
detachable IEC power cord, an external IR remote input, 
and a front mounted 3.5mm headphone output jack. 
For music enthusiasts who won’t accept compromise, 
the RC-1590 preamplier is in a class by itself, at a price  
that belies its incredible performance.
