External Amplifier

Important Note: Before attempting to plug any jacks into any power amplifier verify that the power amplifier is turned off and/or disconnected from the AC mains. Failure to do so can potentially result in severe damage to your amplifier and loudspeakers.

Use the audio jacks labeled main audio outputs to connect the GTP-880 to an external power amplifier such as the ADCOM 7807 power amplifier. The GTP-880 can output up to 7.1 channels of sound (seven satellite and one subwoofer channel) depending on source components and material.

The output jacks supplied by the GTP-880 are:

left front, center, right front, left surround, right surround, left surround back, right surround back, and subwoofer.

Be sure to verify that the correct outputs are connected to the appropriate input jacks (left front to left front, right surround back to right surround back, etc..)

When a powered subwoofer is used, connect the subwoof- er output jack to the Line Input jack on your subwoofer and follow any specific connection and/or configuration instructions supplied with the subwoofer. If your sub- woofer is a passive speaker, connect the subwoofer output jack on the GTP-880 to the input of the amplifier used to power the subwoofer, and then connect the subwoofer speaker itself to the amplifier.

DVD Player

Composite: Connect the composite video output from the DVD player to the DVD video input jack on the rear of the GTP-880 using an RCA-type video cable.

S-video:If there is an s-video output on the DVD player, and you have an s-video input on your TV or monitor, con- nect it to the s-video DVD input on the rear of the GTP-880 using an s-video cable. S-video delivers a better picture than composite connections and should be used whenever possible unless you can use component connections, which deliver better video than s-video.

Component: If the DVD player has component video out- puts, connect them to the DVD component video input jacks on the rear of the GTP-880 using an appropriate cable set. Note: OSD messages do not appear on component video.

Analog Audio: Connect the L and R channel outputs on the DVD player to the DVD in audio jacks on the rear of the GTP-880.

Digital Audio: Connect one of the digital output jacks on the DVD player to one of the coaxial (coax 1-3) or optical (opt 1-3) input jacks on the rear of the GTP-880, depending on the type of connector used by the DVD player. The fac- tory preset for DVD is coax 1. Later, you can configure the GTP-880 to use the specific input that you have chosen.

Use a GFA-7807 Power Amplifier (pictured above) or the GFA-7607 for seven channel surround sound setups. Five channel versions of these amplifiers are also available.
