Theater By-pass Mode

BYPASS indicator

2
The input marked Tape 2 r
for users requiring a unity gain stage through which they can use their
surround sound processor. This input will only function in a by-pass
mode so do not connect a tape recording unit to this input.
To use the By-pass mode, plug the front channel output of the surround
sound processor into the Tape 2 inputs. When the Tape 2 input
is selected, the signal from the processor is sent directly through the
preamplifier and by-passes the tone and volume functions. Once made
a by-pass mode, the BYPASSindicator of front panel is turned on.
Setting a system up this way provides a way to integrate a stereo
amplifier to be used as the front channels of a surround sound system.
Only the Tape 2 input can provide the by-pass function. It requires
no additional setup, making it easy to switch between normal stereo
mode and surround sound mode by using the input selector.
Note: Rotel uses the same operating IR codes for all its audio
products. That means that in a situation where the operator will use a
remote control then it is recommended that the codes for the RR-AT97
and the RC-1580 be changed.
To change the IR code of the RR-AT97, press the Phono button and
the 2 button at the same time.
To change the IR code of the RC-1580, point the RR-AT97 at the
RC-1580 and press and hold the 2 button for 5 seconds. The LED in
the volume control will flash to indicate the IR code has changed.
It's is probably easiest to choose a third party learning remote
control and teach the new source selection codes and those of the
surround sound processor in to it. Alternatively you can use the two
remote controls to operate the different systems.
Note: After changing the remote codes for the remote control and
the preamplifier as described above, the remote control will no
longer operate the Rotel tuners. To return the RR-AT97 IR code to the
default setting, press the Phono button and the 1 button at the same
time. To return the IR code of the RC-1580 to the default setting, point
the RR-AT97 at the RC-1580 and press and hold the 1 button for 5
seconds. The LED in the volume control will flash to indicate the IR
code has changed.
IR Inputs and Outputs

External Remote Input

u
This 3.5 mm mini-jack (labeled EXT REM IN) receives command codes
from an industry-standard infrared receivers (Xantech, etc.) located in
the main listening room. This feature is useful when the unit is installed
in a cabinet and the front-panel sensor is blocked. Consult your
authorized Rotel dealer for information on external receivers and the
proper wiring of a jack to fit the mini-jack receptacle.
Note: The IR signals from the EXTERNAL REMOTE IN jack can be
relayed to source components using external IR emitters or hard wired
connections from the IR OUT jacks.
has been set to provide a by-pass mode
IR Output
i
The IR OUT 1 and 2 jacks send IR signals received at the EXTERNAL
REM IN jack to an infrared emitter placed in front of a source
component or to other Rotel components with compatible rear panel IR
input connectors.
This output is used to allow IR signals to pass along IR signals from
a remote control when the sensors on the source components are
blocked by installation in a cabinet.

See your authorized Rotel dealer for information on IR repeater
systems.
NOTE: The EXT REM IN jack located next to these jacks is for use with
an external IR sensor duplicating the front panel IR sensor and located
in the primary zone.

12V Trigger Connections

Many Rotel amplifiers offer the option of turning them on and off using
a 12 volt trigger signal sent to them. The RC-1580 provides two 12
volt trigger outputs. When the RC-1580 is turned on, a 12 volt DC
signal is sent to the amplifiers to turn them on. When the RC-1580
is put in STANDBY mode, the trigger signal is interrupted and the
amplifiers turn off.
To use the remote turn on feature, connect one of the RC-1580 12V
TRIGGER OUT jacks to the 12 volt trigger input of a Rotel amplifier,
using a cable with mono 3.5 mm mini-plugs on both ends. The +12 V
DC signal appears at the "tip" connector.
Note: The number "1" 12V trigger signal is turned off when
headphones are plugged into the front panel headphone outlet. See
the Phones Output section.
Computer I/O Connector
The RC-1580 can be operated from a personal computer running
audio system control software from third-party developers. This control
is accomplished by sending the operating codes normally sent by the
RR-AT97 remote control over a hard-wired network connection from the
computer.
The COMPUTER I/O input provides the necessary connection on the
back panel. It accepts standard RJ-45 8-pin modular plugs, such as
those commonly used in 10-BaseT UTP Ethernet cabling.
For additional information on the connections, software, and operating
codes for computer control of the RC-1580, contact your authorized
Rotel dealer.
