GTP-870HD Owner’s Manual
6 Analog audio inputs/outputs
• Audio 1~4 inputs (R/L) - Connects to the
line outputs of up to four analog audio
source components.
• Audio 3~4 outputs (R/L) - Connects to the
line inputs of up to two analog audio re-
cording components.
• Aux output (R/L) - Connects to the line
inputs of an analog audio component.
7 Composite/S-video inputs/outputs
• Video 1~4 inputs (CVBS/S-video) - Con
-
nects to the Composite/S-video outputs of
up to four video source components.
• Video tape output (CVBS/S-video) -
Connects to the Composite/S-video inputs
of a video recording component.
8 Monitor outputs/HD bypass transcoder
• Video out (CVBS/S-video) - Connects to
the Composite/S-video inputs of a TV,
monitor, or other display device.
• Video out (Y/Pb/Pr) - Connects to the
Component/Progressive Scan inputs of a
TV, monitor, or other display device.
9 HDMI switcher/scaler
• Video 1~2 in - Connects to the HDMI out
-
puts of an HDMI-compatible source com-
ponent, such as a DVD player, cable box,
satellite receiver, etc.
• Monitor output - Connects to the HDMI
inputs of an HDMI-compatible display de-
vice.
10 Zone 2 IR input
Connects to an IR remote sensor to control the
GTP-870HD from Room 2.
11 RS232 control
Use to control the GTP-870HD with a PC or
home automation system or to upgrade the
receiver’s firmware.
12 Main controls
• Main IR input - Use to connect a remote
IR sensor to control the GTP-870HD if the
front panel display is obstructed (e.g., be
-
hind closed doors).
• Main 12V DC trigger - Used to power on
a compatible component (e.g., an ampli-
fier/receiver or motorized screen) when
the GTP-870HD is turned on. This trigger is
programmable and can be associated with
a specific device.
13 Digital audio inputs
• Coaxial 1~3 (75 ohm) - Connects to the
coaxial digital audio outputs of up to three
digital audio source components.
• Optical 1~3 - Connects to the optical digi-
tal audio outputs of up to three digital au-
dio source components.
14 Voltage switch
Sets the GTP-870HD voltage to 120V (U.S. stan
-
dard) or 230 V (international standard).
15 Main power switch
Switches the GTP-870HD’s main power on (1)
or off (0).
16 AC input
Connects the GTP-870HD to a standard electri
-
cal outlet using the supplied power cord.
17 Balanced audio outputs
Connects to the balanced audio inputs of a
power amplifier using XLR cables to feed up to
seven speakers (RF/RS/RB/C/LB/LS/LF).
18 Component Video inputs
• Video 1~4 (Y/Pb/Pr) - Connects to the
Component/Progressive Scan outputs of
up to four video source components.
19 Subwoofer output
Connects to a powered subwoofer for all
speaker configurations.
20 7.1 Preamp outputs
Connects to the 7.1-channel inputs of a power
amplifier.
