Installation

Read and follow all safety instruc-

tions shown on pages 2 and 3.

Observe the following precautions 

when choosing a location for your 

Theater Grand Amplifier:

• 

Protect it from prolonged 
exposure to direct sunlight and 
other direct sources of heat, 
such as heating vents and 
radiators. 

• 

Do not expose the unit to rain 

or moisture. If fluid or a foreign 

object should enter the unit, 
immediately unplug the power 

cord and contact your Sunfire 

Dealer. 

• 

Avoid excessive exposure to 
extreme cold or dust.

• 

Do not place heavy objects on 
top of the unit.

• 

Allow adequate ventilation 

around the amplifier; do not 

cover the ventilation slots.

AC Power Considerations

Ensure that the unit is plugged into 

an outlet capable of supplying the cor-

rect voltage specified for your model. 

The outlet should be capable of sup-
plying 15 amps for the 120 V model, 
8 amps for the 230 V model.

Care

If you need to clean the front sur-

face, first turn off the power and then 

use a dry soft cloth, rubbing with the 
grain.

Connection Tips

Before setting up your new system, 

please consider the following :

Always make sure that 
your components are all 
unplugged before making or 
changing connections. 

• 

Make sure that the power 
cords of all your components 
are attached to the same outlet 
or at least to the same circuit. 
This will reduce the possibility 
of a ground loop in the system.

Make sure that the total cur-
rent draw does not exceed 
the current rating of your AC 
outlet or power strip.

• 

Use the XLR inputs if your 

preamplifier has XLR outputs. 

These balanced connections 
provide superior noise rejec-
tion.

• 

Whenever possible, keep the 
power cords away from the 
signal cables or speaker wires 
to prevent any hum or audio 
interference being heard in the 
speakers.

• 

Choose reliable hookup cables, 
also called patch cords or RCA 
cables. They should be fully 
shielded and as short as pos-
sible for the job.

•   Some patch cords can be a 

very tight fit and there is usu

-

ally a preferred method of get-
ting them off. Some have to be 
removed with a twisting action. 
Be gentle or you may damage 

the jacks of the amplifier or 

your other components.

•   Some special patch cords 

can only be hooked up in one 
direction, these are usually 
marked with arrows.

•   It is usual for the right patch 

cord plugs to be red and the 
left connections to be white, 
grey or black. Video connec-
tions are usually yellow.

Unpacking

Your Sunfire Amplifier should reach 

you in perfect condition. If you do 
notice any shipping damage, please 

contact your Sunfire Dealer immedi

-

ately.

Gently lift out the unit and remove 

all the packing material and acces-
sories. It is important to save all the 
packing materials and the box in case 

your amplifier ever needs to be moved 

or shipped for repair.

Make sure that you keep your sales 

receipt. It is the only way to establish 
the duration of your Limited Warranty 
and it may come in useful for insur-
ance purposes.

Please take a moment to fill out and 

mail the Sunfire Customer Response 

card. Also read the serial number 
located on the rear panel or the under-
side of the chassis and record it here:
