CHAPTER 1
7. RS-232 Port
This connects to the serial port
of a home computer, allo ing
the TGIII Flash memory soft-
are to upgraded. Latest soft-
are can be do nloaded from
.sunfi re.com.
The port can also connect to the
serial port of a Home Theater
Controller, allo ing the TGIII to be
operated remotely.
8. XLR Audio Outputs
These line-level balanced XLR
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 TGIII.
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 TGIII 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
The TGIII comes ith a de-
tach able linecord hich connects
here.
Plug the linecord into an AC all
socket or po er strip hich is cor-
rectly confi gured ith the voltage
spec i fi ed for your model.
