box),	connect	the	incoming	coaxial	cable	to	the	TV’s	
ANT	input.		Refer	to	page	21.
You	must	perform	a	channel	scan	to	enable	reception	
of	all	available	high-definition	and	standard-definition	
digital	channels.		The	channel		scan	will	search	for	
channels	available	locally	and	save	them	to	memory.

About Auto Input Sensing/
Auto Output Sensing
This	TV’s	Easy	Connect™	Auto	Input	Sensing	feature	
detects	most	connections	automatically.		The	excep-
tions	are:
A	connection	on	the	•	ANT	input
An	HDMI	device	that	is	powered	off.		Power	on	•	
the	device	to	ensure	detection.
Auto Sensing for Most Devices
When	you	first	connect	a	device,	the	TV	will:
a.	 Detect	the	connected	device	and	automatically	
switch	to	it.
b.	 Prompt	you	to	identify	the	device	type.
c.	153 and 249 Series.		Prompt	you	to	perform	
NetCommand	set-up	for	the	device,	if	available.
d.	 Repeat	these	steps	for	any	other	newly	detected	
devices.

TV Connections
Auto Input/Auto Output Sensing
The	TV’s	Auto	Sensing	feature	automatically	recognizes	
most	connections	and	prompts	you	to	identify	the	type	
of	device	connected.		See	page	13	for	more	on	Auto	
Sensing.
Connection Types
Use	the	connection	types	available	on	your	input	
devices	that	will	give	the	best	video	quality.		For	
example,	choose	HDMI	over	component	video,	and	
choose	component	video	over	composite	video.
Picture Quality
For	best	picture	quality,	route	signals	directly	from	the	
input	device	to	the	TV	whenever	possible.
Surround Sound
For	best	surround	sound	audio	quality,	route	audio	or	
HDMI	cables	from	the	source	device	directly	to	your	TV	
(for	Sound	Projector)	or	directly	to	your	A /V	receiver	if	
using	an	external	sound	system.

							18 2. TV Connections
Inputs and Outputs, continued
1.  ANT (Antenna)
Connect	your	main	antenna	or	direct	cable	service	(no	
cable	box)	to	ANT.		The	ANT	input	can	receive	digital	
and	analog	over-the-air	channels	from	a	VHF/UHF	
antenna	or	non-scrambled	digital/analog	cable	source.
2.  HDMI™ Inputs (High-Definition 
Multimedia Interface)
The	HDMI	inputs	support	uncompressed	standard	and	
high-definition	digital	video	formats,	PCM	digital	stereo	
audio,	and	digital	5.1	surround	sound.		These	inputs	
are	HDCP	(High-Bandwidth	Digital	Copy	Protection)	
compliant.
Mitsubishi recommends you use category 2 HDMI 
cables,	also	called	high-speed	HDMI	cables,	to	
connect	HDMI	1.3	source	devices.		High-speed	cat-
egory	2	cables	bring	you	the	full	benefits	of	Deep	Color	
and	x.v.Color.
The	TV’s	HDMI	inputs	are	compatible	with	many	DVI-D	
and	HDMI	computer	video	signals.
Use	the	HDMI	inputs	to	connect	to	CEA-861	HDMI	
compliant	devices	such	as	a	high-definition	receiver	
or	DVD	player.		These	inputs	support	480i,	480p,	720p,	
1080i,	and	1080p	video	formats.
These	HDMI	inputs	can	also	accept	digital	DVI	video	
signals.		To	connect	a	device’s	DVI	output	to	the	TV’s	
HDMI	input,	use	an	HDMI-to-DVI	adapter	or	cable	plus	
analog	audio	cables.		Connect	the	analog	audio	cables	
to	the	DVI/PC INPUT AUDIO	jacks	on	the	TV	to	receive	
left	and	right	stereo	audio	from	your	DVI	device.
3.  Y Pb Pr (Component Video)
Connect	devices	with	component	video	outputs	to	this	
jack.		Use	the	adjacent	AUDIO R	and	L	jacks	if	you	wish	
to	send	audio	to	the	TV.
4.  VIDEO (Composite Video)
Connect	a	VCR,	DVD	player,	standard	satellite	receiver,	
or	other	A /V	device	to	the	TV.		Use	the	adjacent	AUDIO 
R	and	L	inputs	if	you	wish	to	send	audio	to	the	TV.
5.  AVR AUDIO OUTPUT
Use	AVR AUDIO OUTPUT	to	send	analog	audio	of	the	
current	program	to	an	analog	A /V	surround	sound	
receiver	or	stereo	system.		Digital	audio	from	digital	
channels	and	HDMI	devices	is	converted	to	analog	
audio	by	the	TV	for	output	on	this	jack.		This	is	the	only	
audio	connection	needed	to	the	TV	if	using	an	analog	
A /V	receiver	or	stereo	system.
Headphones.		These	jacks	can	also	be	used	for	head-
phones	that	accept	standard	line	level	audio	signals.		
An	adapter	may	be	needed.
6.  DIGITAL AUDIO INPUT
This	input	sends	digital	surround	sound	to	the	TV’s	
speaker	array	from	a	device,	such	as	a	DVD	player,	
connected	to	INPUT 2.
7.  SUBWOOFER OUTPUT
Connect	a	powered	subwoofer	to	complement	Sound	
Projector	speaker	effects.
8.  DIGITAL AUDIO OUTPUT
This	output	sends	Dolby	Digital	or	PCM	digital	audio	
to	your	digital	A /V	surround	sound	receiver.		Incom-
ing	analog	audio	is	converted	by	the	TV	to	PCM	digital	
audio.		If	you	have	a	digital	A /V	receiver,	in	most	cases	
this	is	the	only	audio	connection	needed	between	the	
TV	and	your	A /V	receiver.
9.  DVI/PC AUDIO INPUT
When	connecting	a	DVI	device	to	one	of	the	TV’s	HDMI	
inputs,	use	these	jacks	to	send	left	and	right	analog	
audio	to	the	TV.
HDMI Cable Categories
HDMI	cables	are	available	as	Category	1	and	Category	2	
types.
Category 2 Cables•		(also	called	high-speed	HDMI	
cables).		Newer,	HDMI	1.3-compliant	DVD	players,	
video	games,	and	set-top	boxes	require	Category	2	
cables,	suitable	for	clock	frequencies	up	to	340	MHz	
or	data	rates	of	up	to	10.2	gigabits	per	second.		Use	
category	2	cables	for	high-speed	1080p	HD	signals	
carrying	extended	color	encodings	(i.e.,	30	or	more	
bits,	also	called	Deep	Color).		Category	2	cables	are	
also	suitable	for	standard	HDTV	signals.
Category 1 Cables•		(also	called	standard	HDMI	
cables).		Category	1	cables	may	be	unmarked.		They	
are	suitable	for	standard	HDTV	720p,	1080i,	and	
1080p	signals	with	8-bit	color	depth.		Use	category	1	
cables	for	clock	frequencies	up	to	74.25	MHz	or	data	
rates	of	up	to	2.23	gigabits	per	second.

10.  IR–NetCommand Output/External 
Controller Input
153 and 249 Series.		Use	an	IR	emitter	cable	with	this	
jack	to	send	control	signals	to	external	IR	remote-con-
trolled	devices.		Alternatively,	your	professional	installer	
can	use	this	jack	as	the	input	for	an	external	controller.
Connect	to	this	jack	and	when	the	New Device Found	
screen	appears,	select	operation	of	the	jack	as	either	
an	input	(for	an	external	controller)	or	as	an	output	(for	
NetCommand	IR	control).		See	page	56.
11.  USB
The	TV	can	read	JPEG	photo	files	and	mp3	music	files	
from	a	USB	device.
12.  RS-232C
249 Series.		Use	the	RS-232C	interface	to	receive	
control	signals	from	compatible	home-theater	control	
devices.		See	www.mitsubishi-tv.com	for	a	list	of	
control	signals	for	this	interface.
13.  LAN
249 Series.		Use	the	LAN	Ethernet	jack	for	streaming	
internet	video	to	the	TV.		See	page	37	for	setup.		Visit	
www.VUDU.com	for	details	about	VUDU™	service.
14.  USBa, USBb
249 Series.		Standard	USB	5-volt,	500-milliamp	power
