Rotel RA-1570: Input Signal Connections

RA‑1570 Stereo Integrated Amplifier

volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line 

configuration is noted on a decal on the back panel. 

NOTE: 

Should you move your RA-1570 to another country, it is 

possible to reconfigure your amplifier for use on a different line 

voltage. Do not attempt to perform this conversion yourself. Opening 

the enclosure of the RA-1570 exposes you to dangerous voltages. 

Consult a qualified service person or the Rotel factory service 

department for information. 

NOTE: 

Some products are intended for sale in more than one country 

and as such are supplied with more than one AC cord. Please only 

use the one appropriate for your country/region.

If you are going to be away from home for an extended period of time 

such as a month long vacation, it is a sensible precaution to unplug 

your amplifier (as well as other audio and video components) while 

you are away.

POWER Switch and Power Indicator 

1

Press the front panel Power Switch button, to turn the unit on. The Power 

Indicator light is illuminated when the unit is on. Press Power Switch 

button again to turn the unit off.

When the power switch is in the ON position, the remote control ON 

and OFF buttons may be used to activate the RA-1570. In Standby mode 

the power LED remains lit, but the display is turned OFF.

12V TRIGGER Connection 

u

Some audio components can be turned on automatically when they receive 

a 12V turn on “signal”. The two12V Trigger Outputs of the RA-1570 

provide the required signal. Connect compatible components to the RA-

1570 with a conventional 3.5mm mini plug cable. When the RA-1570 

is in turn off mode, the trigger signal is interrupted, so the components 

controlled by it are turned off.

NOTE: 

If you are using other units in the series with Rotel link, please 

use the Rotel Link connection to turn the units on or off. Do not connect 

both the Rotel Link and 12V trigger cables. The 12V trigger’s power 

on or off features will override the Rotel Link features.

Input Signal Connections 

See Figure 3,4,5 

NOTE:

 To prevent loud noises that neither you nor your speakers 

will appreciate, make sure the system is turned off when you make 

any signal connections.

Phono Input 

0

 and  Ground Connection (GND)

See Figure 3

Plug the cable from the turntable into the appropriate left and right phono 

inputs. If the turntable has a “ground” wire, connect it to the screw terminal 

to the left of the Phono inputs. It will help prevent hum and noise.

Line Level Inputs 

0

See Figure 3

The CD, Tuner, and Aux inputs of the amplifier are analog “line level” 

inputs. These inputs are for connecting components such as CD players 

or other audio playback devices with an analog audio output.

The left and right channels are clearly labeled and should be connected to 

the corresponding channels of the source component. The Left connectors 

are white, the Right connectors are red. Use high quality RCA cables for 

connecting input source components to the RA-1570. Ask your authorized 

Rotel dealer for advice about cables.

Balanced (XLR) Inputs 

=

See Figure 4

A pair of balanced XLR inputs accept audio signals from CD player, Blu-

ray player or other source components with XLR outputs.

NOTE: 

You should choose only one method of ananlog connection 

from a source component to RA-1570. Do not connect both the 

RCA and XLR outputs of a source component to the RA-1570 at the 

same time.

Digital Signal Inputs  q

See Figure 5.

There are two sets of digital inputs labeled COAX 1 and 2, OPT 1 

and 2. Connect the COAXIAL or OPTICAL PCM outputs of your source 

component into these sockets. The digital signals will be decoded and 

played by the amplifier. The unit is capable of decoding PCM signals 

up to 24 bit, 192kHZ.

Preamp Outputs  -

The amplifier has a set of preamp outputs labeled PREOUT 1. The signal 

from the source selected with the Function Selector is always available 

from these outputs. Typically the PREOUT 1 output is used to provide a 

signal to another integrated amplifier or power amplifier, which is used 

to drive remote speakers.

NOTE:

 Changes to the settings of the Volume, Balance or Tone 

controls affect the signal from the Preamp Outputs.

Preamp / Power Amp Jumpers  ey

These connectors, labeled ”Pre Out 2” and “Main In”, are normally 

connected by a set of solid metal jumper connectors. They provide a 

convenient insertion point for virtually any type of signal processor. To 

use these connectors, pull out the jumper connectors. Using high quality 

cables, connect the “Pre Out 2” connectors to the inputs of the signal 

processor. Connect the outputs of the signal processor to the “Main In” 

connectors.
