OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner-preamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

a. Use No.10 AWQ (5.3 mm') copper, No.8 AWG (8.4 mm') aluminum, No.17 AWG (1.0 mm') copper-clad steel or bronze wire, or larger, as a ground wire.

Secure antenna lead-in and ground wires to house with stand-off

insulators spaced from 4-6 feet (1.22-1.83 m) apart.

c. Mount antenna discharge unit as close as possible to where lead-in

enters house. d. Use jumper wire not smaller than No.6 AWG (13.3 mm') copjoer, or the

equivalent, when a separate antenna-grounding electrode is used. See NEC Section 810-21 (j).

EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS

CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT.

The unit should be installed so that its location or position does not interfere

with its proper ventilation. For example, if should not be situated on a bed,

sofa, rug, or similar surface that may block the ventilation openings; or placed in a built-in installation, such as bookcase or cabinet, that may impede the flow of air through its ventilation openings.

The unit should be situated away from heal sources such as radiators, heal

registers, stoves, or other devices (including amplifiers) that produce heat.

The unit should be connected to a power-supply outlet only of the voltage

and frequency marked on its rear panel. The power-supply cord should be routed so that it is not likely to be walked

on or pinched, especially near the plug, convenience receptacles, or where

the cord exits from the unit.

Clean unit only as recommended in its instruction manual. The power-supply cord of the unit should be unplugged from the wall outlet

when it is to be unused for a long period of time. Care should be taken so that objects do not fall, and liquids are not spilled,

into the enclosure through any openings. This unit should be serviced by qualified service personnel when:

A. The power cord or the plug has been damaged; or

B. Objects have fallen, or liquid has been spilled, into the unit; or C. The unit has been exposed to rain, or liquids of any kind; or D. The unit does not appear to operate normally, or exhibits a

marked change in performance; or

E. The device has been dropped, or the enclosure damaged.

DO NOT ATTEMPT SERVICING OF THIS UNIT YOURSELF.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV system installer's attention to Article 820-22 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

INTRODUCTION

Congratulations on your decision to purchase the ADCOM GTP-600 Surround Sound Tuner/Preamplifier. You’ve made a wise choice.

The GTP-600 is ADCOM’s first tuner/preamplifier specifically designed for both audiophiles and videophiles who want the finest in home theater flexibility. The tuner section uses superbly accurate quartz synthesizer technology for excellent FM and AM reception. The preamplifier section derives extensive sonic benefits from ADCOM's exclusive Class A

biased linear amplifiers and precision Roederstein 1% metal film resistors in all critical circuit paths.

The GTP-600 combines advanced Dolby Pro Logic decoding, ADCOM’s proprietary Cinema enhancement circuit,

Digital Signal Processing (DSP) capability, video switching of both standard (composite) and high definition S-video signals, on-screen display and learning remote.

A NOTE ON YOUR OWNER’S MANUAL

In a hurry? The QUICK START section will soon have you up and running. However, we strongly recommend that you refer to the expanded instructions in EVERYTHING YOU NEED TO KNOW to "fine tune" your system for enhanced enjoyment once everything is working.

If you’re more patient or want more background, start with EVERYTHING YOU NEED TO KNOW. You’ll be rewarded

with a much better understanding of how the GTP-600 works and what its capabilities are.

QUICK START

OUT OF THE BOX---

1) UNPACKING: Unpack the GTP-600 carefully, MAKE SURE YOU REMOVE THE REMOTE CONTROL FROM THE

BOX. Put the foam inserts and other packing materials back in the carton and save it.

2) PLACEMENT: Select a stable, vibration-free location for the GTP-600 as close as possible to your other audio

and video components.

3) POWER OFF!: Turn off all the other components in your system. This means everything. And don’t plug the GTP-

600 into the AC outlet yet.

CONNECTIONS

4) FM ANTENNA: Depending on the antenna you use, connect it to either the 75 Ohm terminal © or the 300-Ohm screw terminals © on the GTP-600's rear panel.

The “T" shaped FM antenna supplied with the GTP-600 is a 300 ohm "dipole” and should be connected accordingly. You’ll find it adequate for most installations.

panel.

The supplied AM loop antenna is sufficient for all but the most difficult reception areas. However, it must be oriented for best reception.
