NetCommand IR Control
NetCommand IR home-theater control is avail-•	
able on model L75-A91.
NetCommand IR home-theater control setup is •	
optional.
You can perform NetCommand setup when the TV •	
first recognizes a device during Auto Input Sensing 
or at any convenient time afterward.
NetCommand operates by sending remote control •	
signals from the TV to your other devices via the 
IR (infrared) emitters, telling the devices to play, 
record, change inputs, adjust volume, change 
channels, or perform other functions.  All this is 
accomplished with the TV’s remote control left in TV 
mode.
You may wish to use NetCommand IR control to •	
supplement control of CEC-enabled devices.
Important Note on NetCommand
Be sure to connect the IR emitter cable to the 
TV and properly place the emitters so that 
NetCommand can control your devices.
About NetCommand IR Control 
						

							 5.  NetCommand IR Control 51
In the U.S. call 1(877) 675-2224 for assistance.
The NetCommand system uses emitters connected 
to the IR–NetCommand Output jack to control other 
devices such as DVD players, cable boxes, satellite 
receivers, and VCRs.
Replacement IR emitter cables are available for 
purchase from Mitsubishi.  Request either part 
number 242D483020 (two-ended cable) or part number 
299P254020 (four-ended cable).
Connect the plug end of the IR emitter cable to the 1. 
IR—NetCommand Output jack on the TV back panel.
When the 2. New Device Found screen displays, 
leave IR—NetCommand Output selected.
Highlight 3. EXIT and press ENTER.
The New Device Found screen displays when you 
connect the IR emitter cable.
Position the emitter end with the emitter bulb facing 4. 
the device’s remote control sensor.  The bulb emits 
infrared light in a cone-shaped pattern.  Place the 
bulb far enough from the sensor to allow the cone 
pattern to reach the sensor.
In some cases, the emitter works better facing 
downward from the top of the device.  Experiment 
to find what works best.
Secure the emitter ends in place using double-5. 
sided tape.
Place any unused ends behind the devices to 6. 
prevent stray signals from reaching the IR sensors.

Place IR emitters so the signal can be “seen” by the IR 
sensor on each device.
If You are Unable to Locate 
a Device’s IR Sensor
The IR sensor is usually behind the plastic window •	
of the front display panel.  Using a flashlight, you 
may be able to see it as a round or square cutout.
If you cannot see the sensor and the device’s •	
Owner’s Guide does not specify the location, do 
the following using the device’s remote control.
Starting at one end of the plastic window, hold 1. 
the device’s remote control about one-half 
inch from the front of the device and press the 
POWER key.
If the device does not respond, move the 2. 
remote control one inch toward the center and 
try again.  Repeat until the device responds.
Repeat the previous steps starting at the other 3. 
end of the window.  The sensor will be between 
these two points.
I M P O R TA N T
Position IR emitters so that each device’s 
sensor “sees” the signal from only one emitter.  
Otherwise, a device receiving signals from 
multiple sources (remote controls, IR emitters) 
may not respond at all.

Automatic Audio or Audio/Video Switching
The following setups enable the A /V receiver to switch 
automatically to the correct input when you select a 
device in the TV’s Activity menu.
Three different connection arrangements are described 
here.  Review the descriptions to find the setup needed 
for your equipment.
To hear digital surround sound from a source device 
you must use the setup described for Cases 2 or 3.
To set up control of an A /V receiver you need:
The remote controls for the TV and A /V receiver.•	
An IR emitter cable available from Mitsubishi.•	
Connecting cables•	
Before You Begin
Connect your A /V devices to the TV and connect 1. 
your A /V receiver to the audio outputs on the TV 
and the DVD player.  Note the name of the device 
connected to each A /V receiver input.  See initial 
setup, page 12, and “TV Connections,” page 18.
Position NetCommand IR emitters as described in 2. 
“IR Emitter Placement,” page 51.
Set the TV’s remote control to 3. TV mode using the 
side button.
Open the4.  Inputs > AVR menu, highlight NEXT 
and press ENTER to display the device-key-learning 
menu.
Case 1:  Automatic A/V Receiver 
Switching to the TV Audio Input
Most devices are set up to use the TV’s audio output like 
the VCR in this example; analog audio from the device is 
sent through the TV to the A /V receiver’s TV audio input.
Use this setup for:
Audio Available from TV only.  •	Send audio from 
the ANT input to the A /V receiver from the TV’s 
analog or digital audio output.
Use this setup to make the A /V receiver switch to its 
designated TV audio input when viewing programming 
from the ANT input.
Analog Stereo Audio. •	 Audio from sources with only 
analog stereo output (such as a VCR) can be sent either 
directly to the A /V receiver or through the TV first.
Mitsubishi recommends you send audio through the 
TV as shown in the example.  The TV converts analog 
audio to digital format to send to a digital A /V receiver.
HDMI Digital Stereo Audio.  •	Digital stereo audio 
from an HDMI connection is available both in digital  
and analog format from the TV’s analog and digital 
audio output jacks.
