Rear Usb Power Port - Rotel RAP-1580 Owner's Manual

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.
REM IN Jack o
This 3.5 mm mini-jack receives command codes from third-party IR remote
receiver. These remote IR inputs can be used when the RAP-1580 front IR
receiver cannot be reached by a sending remote control.
Consult your authorized Rotel dealer for more information on the REM IN jack.
The IR signals from the REM IN jack can be relayed to other source components
using external IR emitters or hard-wired connections from the IR OUT jacks.
See the following section for additional information.
IR OUT Jacks
p
The IR OUT 1 & 2 jacks send IR signals received at the REM IN jack to
an infrared blaster or emitter placed in front of a source component's IR
sensor. In addition, the IR OUT can be hard-wired to other Rotel products
with a REM IN jack.
These outputs allow IR signals to be "relayed" through the RAP-1580 either
directly to the IR receiver on the front panel or via the REM IN jack on the
rear panel. This function provides easy control of other source components
when their IR inputs are not accessible such as when they are installed in
a rack system or in a cabinet.
See your authorized Rotel dealer for more information on IR emitters and
repeater systems.

Rear USB Power Port

\
The rear USB port provides 5V for charging or powering USB devices
including streaming music players. This port does not allow playback of audio.
The port can be configured to remain powered even when the RAP-1580 is
in standby mode through the front panel setup menu (See the Power Mode
under the Power Option menu on page 27).
The Power Mode "Quick" option allows the attached streaming source to
remain powered for use with the Signal Sense function for automatic power
on/off control of the amplifier.
When configured to provide continuous power to the rear panel USB port
the RAP-1580 will consume additional power even when in standby mode.
RS232 Connector
y
The RAP-1580 can be controlled via RS232 for integration with automation
systems. The RS232 connector accepts a standard straight DB-9 Male-to-
Female cable.
NETWORK Connector
u
The Network socket accepts standard RJ-45, CAT-5 cables. The network
connection is not required for normal operation of this unit. This connection
is for software updates or control from an automation system only.
For additional information on the connections, cabling, software, and
operating codes for automation system control or software updates, contact
your authorized Rotel dealer.
Making Connections
Connecting Speakers
See Figure 4
This Rotel RAP-1580 has built-in amplifiers to power up to seven speakers:
normally, left/right front speakers, center channel speaker, left/right surround
speakers, plus two center back speakers or two ceiling speakers. There are
seven pairs of binding post connections (one pair for each speaker) which
accept bare wire, spade lugs, or banana plug connectors (in some markets).
Speakers should have an impedance of 4 ohms or higher.
Each pair of connectors is color-coded for polarity: red for positive and
black for negative. All speakers and all speaker wire is also marked for
polarity. For proper performance, you must maintain this polarity at all
speaker connections. Always connect the positive terminal of each speaker
to the corresponding red speaker terminal on the receiver and the negative
speaker terminal to the corresponding black connector on the receiver.
The connectors are labeled LEFT FRONT, RIGHT FRONT, LEFT SURROUND,
RIGHT SURROUND, CENTER, CENTER BACK LEFT, CENTER BACK RIGHT.
Route the wires from the receiver to the speakers. Leave enough slack so
you can move the components to allow access to the speaker connectors. If
you are using banana plugs, connect them to the wires and then plug into
the back of the binding posts. The collars of the binding posts should be
screwed in all the way (clockwise). If you are using terminal lugs, connect
them to the wires. If you are attaching bare wires directly to the binding
posts, separate the wire conductors and strip back the insulation from the
end of each conductor. Be careful not to cut into the wire strands. Unscrew
the binding post collars. Place the twisted bare wire into the hole in the
binding post. Turn the collars clockwise to clamp the connector lug or wire
firmly in place.
For speaker connection information see Audio Configuration options in the
RAP-1580 Setup Menu.
Be sure that no loose wire strands can touch adjacent wires or connectors.
After you have connected the speakers, you need to configure the receiver
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.
Connecting an External Amplifier
See Figure 3
The RAP-1580 also has preamp RCA outputs for connections to external
power amplifiers to drive up to 12 speakers in configurations from 5.1 to
7.1.4. In addition, there are two subwoofer outputs.
To connect amplifiers, connect an audio cable from each output jack to the
input of the amplifier channel that will power the corresponding speaker.
For example, connect the FRONT L output to the amplifier channel driving
the front left speaker. There are two CENTER RCA jacks; use either jack
for a single center channel, or both if you have two center channels. In
six or seven channel systems, make one or two additional connections for
Center Back channel(s). These jacks are labeled CB L[1] and CB L[2]. Use
CB L[1] for a single center back channel. Ceiling or Top speakers should
be connected to the Height 1 and Height 2 jacks.
