Connecting A Subwoofer - Rotel RAP-1580 Owner's Manual

18
For preamp output connection information see Audio Configuration options
in the RAP-1580 Setup Menu on page 23.
After you have connected the preamp outputs, you need to configure the
RAP-1580 for the size and style of speakers in your system and calibrate
the relative volume levels of the speakers. See the Setup section of this
manual on page 23.

Connecting a Subwoofer

See Figure 3
To connect a powered subwoofer, connect a standard RCA audio cable
from the jacks labeled SUB 1/SUB 2 to the input on the subwoofer's power
amp. Both SUB outputs provide the same signal. Use either connection
for a single subwoofer. Use both connections to connect two subwoofers.
After you have connected the subwoofer, you need to configure the unit to
use the subwoofer and calibrate the relative volume level of the subwoofer.
See the Speaker Level Setup section of this manual on page 25.
Connecting a DVD, Blu-ray, Cable, Satellite, Game Console and HDTV Tuner
See Figure 6 and 10
Source devices including Blu-ray, DVD, satellite, cable, etc. should be attached
to the RAP-1580 using HDMI. Connect an HDMI cable from the output of
the source to one of the HDMI inputs on the processor.
Digital audio connection: Depending on the setup of your system, you can also
use the audio digital connections and assign them to the HDMI video inputs.
Connect the digital output of the source to any of the DIGITAL IN OPTICAL
1–3 or DIGITAL IN COAXIAL 1–3 inputs on the processor. An HDMI cable
carries both digital video and digital audio signals; therefore, in most cases
no separate digital audio connection needs to be made.
Use the INPUT SETUP screen to assign the audio digital input to the HDMI
video input source used above.
Connecting a Blu-ray or DVD Player
See Figure 6
In some cases DVD, SACD, and other external multichannel processors are
connected to the processor by sending decoded analog audio signals using
RCA cables. A player with HDMI outputs can send digital signals directly
to the processor for decoding.
Analog Connections: To connect a Blu-ray or DVD player (or any device that
decodes multi-channel audio) with analog connections, use audio RCA cables
to connect the outputs of the player to the RCA jacks labeled MULTI INPUT
on the RAP-1580. Make sure that you observe proper channel consistency,
i.e. connect the right front channel to the FRONT R input, etc.
Depending on your system configuration, make six connections (FRONT L
& R, SURROUND L & R, CENTER, and SUBWOOFER), seven connections
(adding a CENTER BACK connection), or eight connections (adding two
CENTER BACK connections).
RAP-1580 Surround Amplified Processor
The MULTI inputs are analog bypass inputs, passing signals directly to the
Volume Control and preamp outputs, bypassing all of the digital processing.
HDMI digital connection: If the player has HDMI outputs, simply connect
an HDMI cable from the output of the player to one of the HDMI inputs
on the processor. This cable sends the video signal from the player along
with a digital audio signal. Using HDMI for audio and video allows the
multichannel decoding to be handled by the processor.
Connecting a Monitor
See Figure 11
Connect one of the HDMI outputs of the RAP-1580 to the HDMI input of
your TV monitor. The RAP-1580 has two HDMI outputs. Only one HDMI
output will display the OSD and is ARC enabled. This output is labeled on
the rear panel with ARC/OSD.
Connecting a CD Player or XLR Source
See Figure 8
Digital audio connection: Connect the output of the CD player to any of the
Analog CD, XLR, Optical or Coax digital inputs on the processor. Use the
INPUT SETUP menu to assign the audio input to the CD (the default is CD).
Analogue audio connections:
Option 1: Connect the left and right analog outputs from the CD player to
the AUDIO IN jacks labeled CD (left and right). This option uses the CD
player's D/A converter. Depending on the selected DSP mode this connection
method may require the analog signal to be converted to a digital signal
for processing.
Option 2: If your CD Player (or another source) has XLR output connectors,
you can use the XLR inputs on the RAP-1580 for this connection. Connect the
left and right XLR outputs from the source to the jacks labeled BALANCED
INPUT (left and right). This option uses the CD player's D/A converter.
Depending on the selected DSP mode this connection method may require
the analog signal to be converted to a digital signal for processing.
Although there are typically no video connections for a CD Player, the RAP-
1580 can assign another video input to the CD or XLR input. The Video
choices are HDMI 1-8 (Front), Last Video Source, or Off. HDMI 1 video
input is assigned to CD and XLR as the default setting.
Connecting a Tuner
See Figure 9
Digital audio connection: If using an HD Radio or other digital tuner, connect
the digital output of the tuner to any one of the DIGITAL IN OPTICAL 1–3
or DIGITAL IN COAXIAL 1–3 inputs on the RAP-1580.
NOTE: The Tuner source by default does not allow the selection of
a digital input. Please use VIDEO 1 - 8, if connecting a Tuner with a
digital input.
Analog audio connection: If using an analog tuner, connect the left and
right analog outputs from the tuner to the pair of audio input jacks labeled
TUNER on the RAP-1580. Make sure that you connect the right channel to
the R input jack and the left channel to the L input jack.
