IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions before using the product.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.

9. This product, either alone or in combination with a mixer, headphones or speakers, may be
capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long
period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing
loss or ringing in the ears, you should consult an audiologist.

10. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.

11. Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.

12. Only use attachments/accessories specified by the manufacturer.

13. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury
from tip-over.

14. Unplug this apparatus during lightning storms or when unused for long periods of time.

15. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.

16. Do not expose this apparatus to dripping or splashing and ensure that no objects filled with liquids,
such as vases, are placed on the apparatus.

17. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug
from the AC receptacle.

18. The mains plug of the power supply cord shall remain readily operable.

The lightning flash with arrowhead symbol within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
"dangerous voltage " within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying
the product.

WARNING: To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.

Thank you for choosing the G-SERIES amplifiers!

The G-SERIES power amplifiers have been designed to provide great efficiency, dynamics and
reliability at a very affordable price, for a variety of fixed and mobile audio applications.

The G-SERIES circuitry and selected components offer excellent sound quality and high fidelity
audio reproduction. The compact design improves the price/performance ratio, while the rugged
metal chassis guarantees maximum sturdiness. The G-SERIES amplifiers are available in three
models.

G-440

G-440

2 x 210 watts @ 4 ohms

G-850

2 x 350 watts @ 4 ohms

G-1200

2 x 635 watts @ 4 ohms

The G-SERIES amplifiers are equipped with a highly visible LED display system, which provides
precise information on signal status in any lighting condition. The connection system includes XLR
and TRS 1/4" JACKS for audio input and twist-lock connectors for power outputs. Standard 19" rack
mountable sturdy metal chassis makes installation easy while providing maximum protection.

INSTRUCTIONS AND INSTALLATION

ATTENTION !!!

The G-SERIES amplifiers generate high voltage on output.
To avoid the risk of electric shocks. DO NOT TOUCH any bare
wires when the unit is switched on.
This manual contains important information for correct safe use,
read it carefully before using your amplifier.

Connection to main power supply

Before connecting the amplifier to a power socket, always make certain that:

1. The electric system and power socket have adequate grounding compatible with the safety
norms (if you are uncertain, consult specialized personnel);

2. The power supply voltage corresponds to that shown on the rear of the unit (an allowance of up
to +/-10% is accepted);

3. The power cord is not damaged and has no bare wires;

4. The on/off switch is in the off position.
Make sure the amplifier is also off before disconnecting the power cord from the main power
socket.

Switching on and off

In your sound reinforcement system, always switch on the amplifier after all the other equipment
and always switch it off before anything else, if possible with the gain controls set at minimum: this
will avoid annoying and sometimes dangerous signal peaks.

Installation and use
This amplifier generates high power, so install it in locations which ensure correct air circulation.
Avoid long exposure to direct sunlight, sources of strong heat, powerful vibrations, very dusty or
particularly damp surroundings or rain: this will prevent possible faulty operation, deterioration or
even electric shocks and fires. The air for cooling the unit is forced in through the vents in the front
panel and out through those on the rear panel, so make certain that there's sufficient space
around the amplifier to allow adequate air circulation.
If racks or flight-cases are used, make sure that airflow is unobstructed: do not install the amplifier
in racks or flight-cases with closed backs. Since part of the heat is dissipated via the metal bottom
of the amplifier, it's advisable to install the amplifier with at least one rack unit space between
them.

Audio connections

Remember to always connect and disconnect other units with the amplifier switched off. Always
use good quality cables of the appropriate type, described in the "connection cables" chapter of
this manual.
Take care of your connector cables, which are a frequent cause of problems. Check their condition
frequently. Always grip them by the connector, avoid pulling them forcefully and coil them without
forming knots or sharp bends: they'll last longer this way and be more reliable.
