BALANCED Input
d
A Left/Right pair of Balanced XLR audio inputs for connecting a source
component with Balanced XLR audio outputs.
MULTI Input
j
A set of RCA inputs accepting up to 7.1 channels of analog signals from a
source component capable of decoding multi channel audio. These inputs
support FRONT L & R, CENTER, SUB, REAR L & R, and CENTER BACK
L[1] & R[2].
These inputs bypass all digital processing in the RAP-1580MKII and are
routed directly to the volume control and outputs.
PREAMP Output
;
A group of fourteen RCA analog audio outputs sends the RAP-1580MKII's
line level output signals to external amplifiers and powered subwoofers.
These output levels are variable and adjusted by the RAP-1580MKII's volume
control. The fourteen connectors provide output for: FRONT L & R, REAR
L & R, CENTER 1 & 2, CENTER BACK L(1) & R(2), SUBWOOFER 1 & 2,
HEIGHT 1 L & R and HEIGHT 2 L & R.
DIGITAL Inputs
w
The RAP-1580MKII accepts digital inputs from source components such as CD
players, satellite TV tuners, and DVD players. The DSP in the RAP-1580MKII
detects the sampling rate of the incoming signal and automatically adjusts.
Sampling rates up to 192kHz are supported.
NOTE: Digital inputs support both 2 Channel Stereo and Multi Channel
audio signals. When using the digital input with a Multi Channel
audio signal the processor DSP will decode the incoming audio stream
including Dolby or DTS.
There are six digital audio inputs on the rear panel, three coaxial and
three optical. These digital inputs can be assigned to any of the VIDEO
1 - 8 input sources using the INPUT SETUP menu during the setup process.
For example, you can assign the COAXIAL 1 digital input connector to the
VIDEO 1 source and the OPTICAL 2 digital input to the VIDEO 3 source. By
default, the source of the audio for inputs Video 1 - 8 is set to HDMI Audio.
At the factory the CD audio input is set to CD (analog RCA), but this can
be changed to XLR, Coax 1 - 3, or Optical 1 - 3.
PC-USB Input
t
See Figure 5
Connect this input using the supplied USB cable to the USB socket of your
computer.
The RAP-1580MKII supports both USB Audio Class 1.0 and USB Audio
Class 2.0 modes. Windows computers do not require installation of a
driver for USB Audio Class 1.0 and support playback of audio up to 96kHz
sampling rates.
The Factory Default setting is USB Audio Class 2.0. To take advantage of
USB Audio Class 2.0 audio playback supporting up to 192kHz sampling
rates you will need to install the Windows driver supplied on the CD included
with the RAP-1580MKII.
You can switch the RAP-1580MKII to USB Audio Class 1.0 playback mode
with the following:
RAP-1580MKII Surround Amplified Processor
•
Press MENU on the front panel to enter MAIN MENU and use Up/
Down buttons to select the INPUT SETUP menu then press ENTER.
•
Use Left/Right buttons to select "PC-USB" as INPUT SOURCE and select
"USB Audio 1.0" as AUDIO INPUT.
•
Power cycle the RAP-1580MKII and reboot your PC after changing
the USB Audio mode to ensure both units are properly configured.
Many audio playback applications do not support 192kHz sampling rate.
Please confirm your audio player supports 192kHz audio and you have
192kHz audio files to properly playback this sample rate. Also, you may
need to configure the audio driver in your PC to output 192kHz or your
computer may "down sample" to a lower audio sample rate. For more
information please refer to your audio player or operating system information.
NOTE: Upon successful installation of the driver, you may need to select
the ROTEL audio driver from the audio/speaker setup of your computer.
Front USB Input
0
See Figure 7
This connection will accept Apple devices such as iPod, iPad and iPhone.
While connected, the iPod and iPhone displays remain active allowing
search and play functions.
Other Connections
AC Input
'
Your Rotel processor is configured at the factory for the proper AC line
voltage in the country where you purchased it (USA: 120 volts/60Hz AC
or CE: 230 volts/50 Hz AC). The AC line configuration is noted on a
decal on the back of your unit. Plug the supplied cord into the AC INPUT
receptacle on the back of the unit.
Master Power Switch
a
The large rocker switch on the rear panel is a master power switch. When
it is in the OFF position, power to the unit is completely off. When it is in
the ON position, the front panel STANDBY and remote control ON/OFF
buttons can be used to activate the unit or put it into standby mode.
12V TRIGGER Output
i
Many Rotel amplifiers offer the option of turning them on and off using a
12 volt trigger. These three connections provide this 12 volt trigger signal
from the processor. When the unit is activated, a 12 volt DC signal is sent
from these jacks to the amplifiers to automatically turn them on. When the
processor is put in STANDBY mode, the trigger signal is removed and the
amplifiers automatically turn off.
To use the automatic trigger turn on feature, connect one of the RAP-
1580MKII's 12V TRIG OUT jacks to the 12 volt trigger input of a Rotel
amplifier, using only the black 3.5 mm trigger cable included with this unit
or a Rotel amplifier. Do not use any other cable for trigger connection. The
+12V DC signal appears at the "tip" of the connector.
The 12V Trigger outputs are configured to turn on in various combinations
only when specific input sources are activated. See the INPUT SETUP menus
in the Setup section of this manual for details on page 22.
