ROTEL RA-1570 - Manual (Page 9)

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.
