Variable or Fixed Output?

Room 2 Connections

Want to listen to a CD in the den while the kids are watching a movie in the family room? Follow these steps to connect the GTP-870HD to a sound system in a second room.

Before you connect your Room 2 sound system, you need to determine whether to use the Variable or Fixed audio outputs:

•If your Room 2 sound system does NOT have its own volume control (e.g., an ampliﬁer), use the Variable outputs and adjust the Room 2 volume from the GTP-870HD.

•If your Room 2 sound system DOES have its own volume control (e.g., a stereo receiver or other audio component), use the Fixed outputs and ad- just the volume from the Room 2 device.

Connecting the Zone 2 Outputs

1Connect the Room 2 ampliﬁer/audio compo- nent.

•Using RCA cables, connect the Var or Fixed outputs on the GTP-870HD to the line or aux inputs on your Room 2 ampliﬁer/audio com- ponent.

•If you are using the Fixed outputs, make sure the volume level on your external component is turned all the way down before switching to Room 2 to prevent damage to your speak- ers.

Connecting the 12V DC Trigger

If your external device is equipped with a 12V DC trigger, you can have the device power on automati- cally when you select Room 2 from the GTP-870HD.

1Connect the 12V DC trigger.

•Using a cable with two mono mini-plugs, connect the 12V DC trigger jack from the GTP-870HD to the 12V DC trigger jack on your external component.

•Now when you press the Room 2 button, the sound system in Room 2 will power on auto- matically.

Connecting a Remote Sensor

If you want to be able to control the GTP-870HD while in the second room, simply connect an IR sen- sor to the Zone 2 remote input.

1Connect the Zone 2 remote sensor.

•Using a remote sensor with a cable long enough to reach between rooms, connect the cable’s mini-plug into the Zone 2 IR input jack on the GTP-870HD.

2Attach the remote sensor in Room 2.

•Following the manufacturer’s instructions, attach the remote sensor in a suitable place in Room 2.
