CHAPTER 1
6. Level
Rotate this manual control clock-
 wise to increase the volume. 
The dB level will appear in the 
front panel display. Note that the 
control knob does not rotate when 
the remote is used. When turning 
on a new source, make sure the 
level is low, such as -80 dB and 
increase it slowly. The dB display 
becomes less negative as the 
volume increases. 
Note: When the TGIV is turned 
on, it has a de lib er ate ly slow 
and smooth volume ramp from 
silence, up to the level that was 
set when the unit was last turned 
off. It can also be set to come up 
to a preset volume you can select, 
rather than the previous volume.
7. Power
This turns the TGIV on or off. It is 
a non-latching mo men tary button. 
If you press ZONE TWO fi rst, it 
can turn on Zone 2 (even if the 
Main Zone is off).
8. Illuminated Logo Panel
This warmly lit panel is always 
on, and shows the fundamental 
technologies of the TGIV.

10. Tuner Controls
AM/FM
This button toggles between 
the AM or FM band. Press and 
hold it to engage a scan of the 
station presets. Press it again 
or press a preset button to stop 
the scan.
DIRECT
Use this to enter a station’s 
fre quen cy directly using the 
0 - 9 keys, such as 9, 5, 7 for 
95.7 MHz. 
UP/DOWN
Switch to stations above or 
below the fre quen cy of the 
current station. If repeatedly 
pressed, the tuner will move 
up or down one frequency step 
each time. If held down for a 
second or more, the tuner will 
au to mat i cal ly keep tuning sta-
tions. Press UP or DOWN once 
again to stop when it reaches a 
station you like.
11. Tone
To change the tone, fi rst press 
BASS or TREBLE and then press 
UP or DOWN to suit your taste. 
The display will show the change 
in dB level for ref er ence. The 
range for both BASS and TREBLE 
is +/- 10 dB in steps of 1 dB.
Note: The Tone controls do not 
affect the LFE channel, or the 
8-Channel analog input
The unit returns to its normal 
display after a few moments of 
inactivity, and any level changes 
are retained.
The BASS and TREBLE levels 
can also be adjusted using the 
OSD TONE Menu and the remote 
control.
12. Full Au to mat ic 
 Operation
When this is engaged, the 
TGIV will au to mat i cal ly switch to 
the next input which starts to play. 
For ex am ple, if you turn on your 
CD player and press Play, the 
TGIV will switch to CD. When you 
turn on your VCR and press Play, 
it will select the VCR input.
If the TGIV is turned off while the 
Auto mode is engaged, it will turn 
on and select an input when ev er 
an input be comes active. For 
example, if you turn on your CD 
player and press Play, the TGIV 
will turn on and select the CD 
input.
We recommend that you turn off 
this feature if you are se lect ing the 
inputs manually, or re cord ing.
Repeatedly pressing the Fully Au-
tomatic button will cycle through 
the active inputs.
Note: The automatic input switch-
ing will not occur unless the 
FULLY AUTOMATIC OPERATION 
button has been pressed (its light 
is on).
13. Manual Input Selector
Use this control to select the 
source you want to listen to.
Note: After you have selected an 
input, you should check that the 
TGIV is set to the desired sur-
round mode (or the stereo mode).
Using the On Screen Display 
(OSD) INPUTS menu, each input 
can be adjusted in level so that all 
the inputs have similar volumes. 
Each input can also be set to 
enter a desired surround mode 
whenever that input is selected.
