RA‑1570 Stereo Integrated Amplifier

Getting Started

Thank you for purchasing the Rotel RA-1570 Stereo Integrated Amplifier. 

When used in a  high-quality music audio system, it will provide years 

of musical enjoyment. 

The RA-1570 is a full featured, high performance component. All aspects 

of the design have been optimized to retain the full dynamic range and 

subtle nuances of your music. The RA-1570 has a highly regulated power 

supply incorporating a Rotel custom-designed toroidal power transformer 

and custom-made slit foil capacitors. This low impedance power supply has 

ample power reserves, which enables the RA-1570 to easily reproduce 

the most demanding audio signals. This type of design is more expensive 

to manufacture, but it is better for the music. 

The printed circuit boards (PCB) are designed with Symmetrical Circuit 

Traces. This insures that the precise timing of the music is maintained 

and faithfully recreated. The RA-1570 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. 

The main functions of the RA-1570 are easy  to install and use. If you 

have experience with other stereo systems, you shouldn’t find anything 

perplexing. Simply plug in the associated components and enjoy. 

A Few Precautions

WARNING: 

To avoid potential damage to your system, turn off ALL 

the components in the system when connecting or disconnecting the 

loudsp-eakers or any associated components. Do not turn the system 

components back on until you are sure all the connections are correct 

and secure. Pay particular attention to the speaker wires. There must 

be no loose strands that could contact the other speaker wires, or 

the chassis of the amplifier.

Please read this manual carefully. In addition to basic installation and 

operating instructions, it provides valuable information on various RA-1570 

system configurations as well as general information that will help you get 

optimum performance from your system. Please contact your authorized 

Rotel dealer for answers to any questions you might have. In addition, 

all of us at Rotel welcome your questions and comments.

Save the RA-1570 shipping carton and all enclosed packing material for 

future use. Shipping or moving the RA-1570 in anything other than the 

original packing material may result in severe damage to your amplifier.

Fill out and send in the owner’s registration card packed with the RA-1570. 

Also be sure to keep the original sales receipt. It is your best record of 

the date of purchase, which you will need in the event warranty  service 

is ever required.

Placement 

Like all audio components that handle low-level signals, the RA-1570 

can be affected by its environment. Avoid placing the RA-1570 on top 

of other components. Also avoid routing audio signal cables near power 

cords. This will minimize the chance it will pick up hum or interference. 

The RA-1570 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 10 cm (4 inches) of clearance around the chassis, and reasonable 

airflow through the installation location, to prevent the amplifier from 

overheating. 

Remember the weight of the amplifier when you select an installation 

location. Make sure that the shelf or cabinet can support it. We recommend 

installing the RA-1570 in furniture designed to house audio components. 

Such furniture is designed to reduce or suppress vibration which can 

adversely affect sound quality. Ask your authorized Rotel dealer for advice 

about component furniture and proper installation of audio components.

The RA-1570 is supplied with an RR-AX92 remote control and must be 

placed where the infrared signal from the remote can reach the front 

panel Remote Sensor.

Cables 

Be sure to keep the power cords, digital signal cables and regular 

audio signal cables in your installation away from each other. This will 

minimize the chance of the regular audio signal cables picking up noise 

or interference from the power cords or digital cables. Using only high 

quality, shielded cables will also help to prevent noise or interference from 

degrading the sound quality of your system. If you have any questions 

see your authorized Rotel dealer for advice about the best cable to use 

with your system.

The RR‑AX92 Remote Control

Some functions can be done with either the front panel controls, or the 

supplied RR-AX92 remote control. When these operations are described, 

the square call out numbers refer to the main unit, while the encircled 

letters refer to the remote control. 

NOTE: 

The remote control can be used to operate the basic functions 

of Rotel tuners and CD players. Remote control keys labeled 

GHMN

can be used to operate CD or Tuner functions in your system. For the 

remote to operate properly, make sure both the remote and the CD 

or Tuner are both in same remote code.

Remote Control Batteries

Two UM-4/AAA size batteries (supplied) must be installed before the 

remote control can be used. To install the batteries, remove the cover on 

the back of the RR-AX92. Install the batteries as shown in the illustration 

in the battery well. Test the control for proper operation, then replace 

the cover. When the batteries become weak the remote control won’t 

operate the RA-1570 consistently. Installing fresh batteries should eliminate 

the problem.

AC Power and Control 

AC Power Input 

i

Because of its relatively high power rating, the RA-1570 can draw 

considerable current. Therefore, it should be plugged directly into a 

2-pin polarized wall outlet. Do not use an extension cord. A heavy duty 

multi-tap power outlet strip may be used if it (and the wall outlet)  is 

rated to handle the current demanded by the RA-1570 and all the other 

components connected to it.

Your RA-1570 is configured at the factory for the proper AC line voltage 

in the country where you purchased it (either 120 volts AC or 230
