5. Infrared (IR) Inputs
These are used in custom in stal -
la tions to control the Main Zone
and Zone 2 from a remote loca-
tion. The input accepts 1/8” mono
mini-jacks from standard remote
control IR equipment, such as
those made by Xantech and other
companies. The remote sensors
can be in a different room, or in
a preferred location in your main
room.
6. Triggers and Relay
The relay s itch is normally open,
and it ill close after a short delay,
hen selecting a source. This can
be used in in stal la tions to trigger
video screen deployment, or other
custom purposes. The OSD
INPUTS menu allo s you to
choose hich inputs ill activate
the relay.
The +12 VDC outputs are on
henever their zone is enabled.
Sunfi re amplifi ers have a
+12 VDC input hich allo s them
to be turned on automatically by
the TGIV. The 1/8” mini-jack is
ired in parallel ith the termi-
nals. Do not exceed a current
dra of 500 mA total for both
outputs.

1. Audio/Video Inputs
These audio, composite-video
and S-video inputs con nect to the
outputs of your audio video com-
po nents. When these inputs are
selected, the audio ill be heard
in your system and the video ill
be seen on the TV screen. VID2
can be used for a second VCR.
2. Audio/Video Outputs
MAIN: connects to the inputs of a
TV monitor, here the video
of any selected input and the
On Screen Display (OSD) can
be vie ed. The audio con nec -
tions allo you to listen to any
selected audio source through
your TV’s speak ers.
VCR: connects to the inputs of a
VCR to allo recording.
VID2/MON2: connects to the input
of a second VCR for recording,
or to a second TV. When con-
fi gured in the OSD for “VID2,”
this output is muted henever
the VID2 input is selected. This
prevents feedback; also there
is no OSD then on this output.
When confi gured for “MON2,”
the output is al ays active, the
same as the Main output.
Note: Analog audio signals are
present at these L and R outputs
even if a digital input has been
selected. The output is a 2 chan-
nel do nmix if the digital source is
more than 2 channels.
3. Component Video In
These inputs con nect to the
component-video outputs of your
DVD, SAT or other video source
(VID1) if they have this advanced
capability. When these inputs are
se lect ed, the TGIV ill au to mat i-
cal ly route any video signals going
into these jacks to the component
video outputs. Note that com-
ponent video provides the best
picture compared to composite
or S-video. The TGIV can also
s itch HDTV signals.
4. Component Video Out
If your TV Monitor has component
video inputs, connect them to
these outputs. If you select DVD,
SAT or VID1, then any video sig-
nals going to the component
inputs ill pass through to your
TV monitor. The TGIV can also
up-convert composite video and
S-video from the other inputs.

outputs connect to the XLR inputs
of your amplifi ers and po ered
sub oofer. The outputs are: front
left, front right, center, left sur-
round, left surround back, right
surround back, right surround and
one sub oofer (LFE) output.
If your amplifi er has a choice of
inputs, e recommend using the
XLR balanced type. This gives
better noise rejection, especially
for longer cable runs.
9. FM Antenna
The supplied FM antenna fi ts
this “F-type” scre -on connector.
Other antennas can be fi tted for
improved re cep tion.
10. AM Antenna
These con nec tions are for the
included AM loop antenna.
11. Ground Scre
This is commonly used for the
ground con nec tion ire of a turn-
table, to prevent any hum in your
speakers. It is tied to the chas-
sis ground, and may be used as
needed.
Note: It is not necessary or desir-
able to connect this to an electri-
cal ground.
12. Audio Inputs
These audio inputs connect to
the outputs of your turntable, DAT
or TAPE player. Any standard
audio component ith a line-level
output can be con nect ed to DAT
or TAPE. Only a turntable ith a
moving-magnet, or high-output
moving-coil cartridge can be con-
nected to the PHONO input.
13. Audio Outputs
These audio outputs connect to
the analog record inputs of your
tape decks, such as DAT, cas-
sette or reel to reel. These outputs
allo you to record the selected
audio program. Note that these
also allo analog re cord ing from
digital audio sourc es.
14. 8-CH Input
These analog audio inputs can
connect to the output of an ex-
ternal surround processor, or a
source component such as DVD-
Audio, SACD, or a DVD player
ith its o n surround decoder.
You can select this as an input
from the front panel or remote
control. The eight channels of
analog audio ill then pass into
the TGIV.
Note: This is designed to be a
very short analog-only signal path.
DSP-based effects such as tone
controls, bass management and
DSP surround are bypassed. This
input is not available in Zone 2.
15. Stereo Outputs
FIXED MAIN is a line level output,
and the volume is not adjustable.
This can be used as a record
output, or to feed another audio
system.
ZONE 2 connects to the inputs
of a stereo amplifi er to run Zone
2. The volume and source are
adjustable, either from the front
panel, or from a remote IR sensor.
16. Digital Inputs
These inputs connect to the digital
outputs of your audio/video com-
po nents. The DVD, SAT and VID1
and CD inputs have t o op tions,
optical or coaxial. The DAT and
VID2 inputs are coaxial only.
Whenever one of these inputs is
selected from the front panel or
remote, the TGIV ill au to mat i-
cal ly select the digital input if there
is a signal present, other ise
it ill select the cor re spond ing
analog input.
17. Main Audio Out puts
These line-level RCA outputs con-
nect to the inputs of your ampli-
fi ers and po ered sub oofer(s).
There are outputs for front left,
front right, center, left surround,
left surround back, right surround
back, right surround and three
identical sub oofer (LFE) outputs.
18. Digital Output
This S/PDIF output is active for
all sources except the 8-chan-
nel input. It allo s you to record
digital audio, for ex am ple to a DAT
or CD-R.
19. Side-Axis Outputs
These outputs provide t o
optional front side channels to
com ple ment the left, center, right,
surround and surround back
chan nels. They can be turned
on or off using the Speaker Size
OSD menu (see page 38).
20. IEC Linecord Socket

CHAPTER 1
Observe the follo ing precautions
hen choosing a location for your
TGIV:
• Protect it from pro longed
ex po sure to direct sunlight and
other direct sources of heat,
such as heating vents and
ra di a tors.
• Do not expose the unit to rain
or moisture. If fl uid or a for-
eign object should enter the
unit, immediately turn off the
po er and contact your Sunfi re
Dealer.
• Avoid excessive exposure to
extreme cold or dust.
• Do not place heavy objects on
top of the unit.
AC Po er Con sid er ations
Ensure that the unit is plugged into
an outlet capable of supplying the cor-
rect voltage specifi ed for your model.
Care
If you need to clean the front sur-
face, fi rst turn off the po er and then
use a soft dry cloth, rubbing ith the
grain. Be careful not to scratch the
display indo .
Connection Tips
Before setting up your ne sys tem,
please consider the follo ing :
Al ays make sure that your
com po nents are all turned
OFF, or unplugged before
making or changing any
connec tions.
• Whenever possible, route the
po er cords a ay from the
signal cables or speaker ires
to pre vent any hum or in ter -
fer ence heard in the speak ers.
• Choose reliable hookup cables.
They should be fully shield ed
and as short as pos si ble.
• Use quality coaxial digital
cables to connect the TGIV to
any source equipment hich
has coaxial digital outputs.
• Some patch cords can be a
very tight fi t and there is usu-
ally a preferred method of get-
ting them off. Some have to be
removed ith a t isting action.
Be gentle or you may dam age
the jacks of your TGIV, or other
com po nents.
• Some audiophile cables should
be hooked up in one direction,
these are usually marked ith
arro s.
• It is usual for the right channel
patch cord plugs to be red and
the left channel con nec tions to
be hite, grey or black. Com-
pos ite video con nec tions are
usually yello .
• If your amplifi er has XLR
inputs, use balanced connec-
tions as they provide superior
rejection of hum and noise,
especially if long cables are
required.
Video Connections
The TGIV has three types of video
connections: composite video,
S-video, and com po nent video.
Choose component or S-video if your
video system supports it, as this ill
give better picture quality than com-
posite video.
When an audio/video component
is selected, the audio ill play in your
system and the video ill be s itched
to a video input of your TV mon i tor.
You must have the TV connected
in order to see the On Screen Display
(OSD). For component video OSD,
only the system setup menus are
available, not the pop-up text (volume,
source etc.) hich appear on the com-
posite or S-video outputs.
Video Screen Trigger
The Main Zone and Zone 2
12 VDC terminals each supply 12
VDC henever that zone is turned
on. This can be used to turn on po er
amplifi ers equipped ith a 12 V trigger
input.
The t o middle ter mi nals marked
as re lay con tacts are con nect ed to-
geth er only hen the Main Zone is on
and an in put is se lect ed for hich the
trigger output is enabled. The OSD
INPUTS Menu can be used to select
hich inputs have the trigger output
enabled or disabled (see page 34).
Use all stan dard safe ty pre-
cau tions and make sure all
the equip ment is dis con nect ed
be fore making any con nec -
tions.
Here are t o connection options:
DO NOT use the relay con-
tacts for 120 VAC or 240 VAC
s itching! They are only for
lo voltage AC/DC loads of
2 A maximum.

Digital audio and component video connections
If your DVD and TV Monitor both
have com po nent-video, they can be
connected as sho n, giving a superior
picture.
The digital output from the DVD
player must be con nect ed to the digi-
tal inputs of the TGIV. This is the only
ay the TGIV can receive and decode
Dolby Digital or DTS signals. It is best
to use a coaxial digital cable to make
the connection to the TGIV, rather
than a standard audio cable.
Note: you must also connect the
player's t o-channel audio outputs if
you ant it to play it in Zone 2 hen
the Main Zone is playing a different

LD connections: external RF Demodulator and S-Video
A suitable external RF demodula-
tor must be used to convert the AC-3
RF output of LD players. Ideally, the
demodulator should also have a
digital bypass (pass-through) feature.
Lexicon and B&K are among several
com pa nies making excellent de mod u-
la tors ith this feature.
If your LD and TV Monitor both have
S-video, they can be connected as
sho n. This gives a better picture
than composite video.
Note: you must also connect the
