reinforce the low-end frequency response of the system.
80Hz low-pass crossover for subwoofer: 12 dB/octave
Down Position: LPF/HPF complete bypass path (analog
multichannel input bass management disabled)
This position is ideal for DVD-Audio/SACD multichannel
players which already include integrated bass management,
a user has another multichannel analog bass management
device, or all speakers in the system are full-range.

Main Analog Audio outputs
Use the seven audio channel output jacks to connect the
GTP-880 to an external power amplifier. The eighth jack
supplies the output to a powered subwoofer or external
subwoofer amplifier.

Digital Audio Inputs
Use these inputs to connect the coaxial and optical digital
audio signal output from such digital devices as CD, DVD or
LD players. These inputs are fully assignable using the OSD.

Digital Audio Outputs
Use the coaxial and optical digital outputs to connect the
GTP-880 to a device such as CD recorder, DAT recorder, or
other similar device that accepts a digital audio input.

Main Power Switch
Turns the current to the GTP-880 on or off. Setting this
button to the on position (pushed in) supplies power to
the unit, enabling use of the standby power button on
the front panel. When the main power switch is in the off
position, current is cut off to the unit.

AC Input
Use to connect the supplied AC power cord (see page 2).
Before proceeding, please observe the following precau-
tions when connecting devices to your new GTP-880.
Do not plug the power cord into your GTP-880 until
all other connections have been made.
Insert the supplied power cord into the AC input of the
rear panel of the GTP-880. Do not use a power cord other
than the one supplied with the GTP-880. It’s designed for
use with the GTP-880 and should not be used with any
other device.
Caution: Before you plug the power cord into an AC wall outlet, con-
firm that all connections to the GTP-880 have been made correctly.
Warning: Never disconnect the power cord from the GTP-880
while the other end is plugged into an AC outlet. Doing so may
cause an electric shock. Always connect power by plugging into
the AC outlet last and disconnect by unplugging from the AC
outlet first.
1.7 Connecting Components
Always refer to the instructions that came with the com-
ponent that you are connecting for specific procedures,
warnings and options.
For all analog connections, the red input jacks (R) are
used for the right channel, white input jacks (L) are used
for the left channel, and yellow input jacks (V) are used
for the composite video connection.
Make sure to insert all plugs and connectors securely. Im-
proper connections can result in noise, poor performance,
or damage to the equipment.
Do not bundle audio/video connection cables with power
cords and speaker cables. Doing so may adversely affect
the picture and sound quality. For example, run all the
power cords down one side of the cabinet, all the signal
cords down the other side, and the speaker wires down
the center.
When connecting devices to the digital inputs and outputs,
you may also consider hooking up the analog connections
to and from the components to insure that all signals can
be employed by the GTP-880.
When using the optical input or output jacks, remove the
protective cap and keep it in a safe place. When these
jacks are not in use the protective cap should be replaced.
When using an optical input or output jack, always use a
high-quality optical fiber cable.
Important Note: We strongly recommend that before you
connect any loudspeakers to your amplifiers, you complete
all needed connections and set up procedures to your GTP-
880 as outlined below. This will reduce the chance that a
miss connection or other error will produce audio output
that might damage your speakers or other components.
