PRODUCT FEATURES

1.2Rear Panel Inputs & Outputs - System Connections

Like the front panel, the GTP-830’s rear panel is

carefully arranged to make hookup, configuration,

and use as simple as possible. However, the

GTP-830’s extraordinary capabilities take some

study to use most effectively. We strongly suggest

that you read this section of the manual before

beginning to hook up your system. You will save

yourself much time and effort if you carefully think

out what you expect from your system: consider

the components you will use, where they’ll be

placed, and how you will want them to work together.

The diagrams and notes in this section will proba-

bly answer most of your questions about interfac-

ing the GTP-830 with other components in

your system.

Note that the GTP-830’s RCA-style jacks have color- coded centers to make connections easier. Use this key to help route cables properly:

RED centers = RIGHT CHANNEL ANALOG AUDIO inputs

WHITE centers = LEFT CHANNEL ANALOG AUDIO inputs

YELLOW centers = VIDEO inputs (composite)

BLACK centers = DIGITAL AUDIO inputs and CENTER CHANNEL and SUBWOOFER inputs and outputs

[14] Antenna connections:

AM Antenna: An AM loop antenna is supplied with the GTP-830 and is required for AM reception. Open the clip terminal lever and insert the wire from the antenna. Closing the lever will lock the wire in place. Test various positions for the antenna, but always ensure the loop is placed vertically for best reception. Placing the antenna close to large metal items such as metal shelves or radiators may inter- fere with reception.

NOTE:

When reception is not satisfactory using the supplied AM loop antenna alone, connection of an external antenna is recommended. The antenna cable to the loop antenna must not exceed three meters.

FM Antenna: A ribbon wire FM antenna is included and should be connected to the FM connector at the rear of the unit using the ‘balun’ adapter supplied.

The ribbon aerial should be mounted on a vertical surface and placed so that it forms a ‘T’.

Experiment with placement of the antenna to find the position that gives the best signal strength and lowest background noise. An inadequate FM signal normally results in high levels of hiss, especially in stereo, and interference from external electrical sources. In areas of poor FM reception, the tuner section’s performance can be improved by using an externally mounted FM antenna. A qualified aerial installer will be able to advise and fit a recommend- ed aerial for your reception conditions.
