CHAPTER 1

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 switch is normally open, 
and it will close after a short delay, 
when 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 allows you to 
choose which inputs will activate 
the relay. 

The +12 VDC outputs are on 
whenever their zone is enabled. 
Sunfi re amplifi ers have a 

 

+12 VDC input which allows them 
to be turned on automatically by 
the TGIV. The 1/8” mini-jack is 
wired in parallel with the termi-
nals. Do not exceed a current 
draw 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 will be heard 
in your system and the video will 
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, where the video 
of any selected input and the 
On Screen Display (OSD) can 
be viewed. The audio con nec -
tions allow you to listen to any 
selected audio source through 
your TV’s speak ers.

 VCR: connects to the inputs of a 

VCR to allow 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 whenever 
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 always 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 downmix 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 will 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 
switch 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 will pass through to your 
TV monitor. The TGIV can also 
up-convert composite video and 
S-video from the other inputs.
