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 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.
NOTE: Place the self adhesive ring over the light surrounding the Power
switch if the blue light is too bright.

12V TRIGGER Connection u

Some audio components can be turned on automatically when they receive a
12V turn on "signal". The two 12V 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 0=

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.
RA‑1570 Stereo Integrated Amplifier
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 analog 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
RA‑1570. The unit is capable of decoding PCM signals up to 24 bit, 192kHz.

Preamp Outputs -

The RA‑1570 has a set of preamp outputs labeled PRE OUT 1. The signal
from the source selected with the Function Selector is always available from
these outputs. Typically the PRE OUT 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.
