[18] Composite Video Inputs
Use these inputs for connection to the composite video output from sources such as a DVD or LD player, satellite receiver, cable box, PVR or other video source. Note that when the component video inputs are used, connect the analog audio outputs of the source to the DVD or video 1 jacks, as appropriate.
[19] Composite Video main Output
Connect this output to the composite video input of your monitor or other video display device.
[20] 12V DC Trigger (main/room 2)
The DC trigger jacks are used to remotely turn-on other devices in your system when the GTP-880 is powered on. Power is applied to the main trigger output jack when the GTP-880 is turned on from the standby mode. We recom- mend that this jack be used to turn on a compatible power amplifier such as those available from ADCOM, but it may also be used to activate compatible products such as projection screens or motorized blinds.
Connect a mono mini-plug between the DC trigger main jack on the rear panel of the GTP-880 and the low voltage trigger jack of the device to be controlled to enable re- mote turn-on of that component. The room 2 trigger jack is activated when the room two system is turned on and should be used for control of amplifiers used to power the speakers installed in room two. It will remain activated as long as the room two system is on, even when the GTP-880 is in the standby mode for the main room.
[21] IR Inputs (main/room 2)
Use the main and room two remote jacks to connect external IR sensors to the GTP-880. When the unit is installed behind doors or where it is not otherwise visible to the remote, connect an optional, external sensor to the main jack. To control the GTP-880’s room two system from a remote location, connect an optional remote sensor in the second room to the room two jack.
The remote jacks allow you to extend the on-board remote control sensor on the GTP-880’s front panel so that you may continue to control the GTP-880 even when it is installed behind solid or smoked cabinet doors or when the front panel sensor is otherwise not visible to the remote control.
To extend the remote sensor connect an optional remote sensor to the main jack.
The room two jack is provided to enable remote control of the GTP-880’s room two system through the use of an optional remote sensor in the second room. Connect the sensor to the room two jack using a mono mini-plug and the wiring specified by the sensor’s manufacturer.
[22] Room 2 Analog Audio Output
Use these jacks to supply the analog stereo audio output to an optional audio amplifier used to power the speakers in room two.
Use the L and R channel room two out audio jacks to con- nect the GTP-880 to the analog audio inputs of an external amplifier or other audio component in a second room. The analog signal present will reflect the input selection of the GTP-880. This may be adjusted using the room two menu or the rm. 2 button on the remote control.
[23] RS232 Control (DB9)
Allows control of the GTP-880 via computer or home automation system.
[24] SACD Inputs (DB25)
Connect the multichannel signal from the analog audio outputs of a device such as a DVD, DVD-A or SACD.
[25] DVD Audio Inputs
Connect the multichannel signal from the analog audio outputs of a device such as a DVD, DVD-A or SACD.
[26] Multichannel Analog Bass Management
Analog bass management is totally separate from the DSP bass management, set up using a three position switch on the rear panel, and applied to multichannel analog inputs.
Up Position: LPF/HPF both on
This position is ideal for owners who have speakers that only have a frequency response that goes down to around 80Hz (@-3dB). All bass information is summed, low-pass- filtered (@ 80Hz) and sent to the subwoofer.
80Hz high-pass crossover for L, C, R, LS, and RS: (12dB/octive)
80Hz low-pass crossover for subwoofer: (12dB/octive)
Middle Position: LPF on/HPF bypassed (subwoofer bass reinforcement mode)
This position is also ideal for owners who have speakers in their system that are full range (or at least have a frequency response that extends below 80Hz) however the user still desires that summed and low-pass-filtered audio information be sent to the subwoofer which helps to
