RISQUE DE CHOC ELECTRIQUE

No user serviceable parts inside. Refer servicing to qualified service personnel.

CAUTION

WARNING:

TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK DO NOT EXPOSE
THIS EQUIPMENT TO RAIN OR MOISTURE

DO NOT OPEN

RISK OF ELECTRIC SHOCK

The lightning flash with arrowhead 

symbol within an equilateral triangle is 

intended to alert the user of the pres-

ence 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 of 

the presence of important operating and 

maintenance (servicing) instructions in 

the literature accompanying the product 

(i.e. this quick start guide).

CAUTION

   To prevent electric shock, 

do not use the polarized plug supplied 

with the unit with any extension cord, 

receptacle, or  other outlet unless the 

prongs can be fully inserted.

Important Safety Instructions.

   

Please read and keep these instruc-

tions. Heed and follow all warnings and 

instructions. Install in accordance with 

the manufacturer’s instructions.

Power Source.

   This product is 

intended to operate from a power source 

that does not apply more than 250V 

RMS between the power supply conduc-

tors or between either power supply con-

ductor and ground. A protective ground 

connection, by way of the grounding 

conductor in the power cord, is essential 

for safe operation.

Grounding.

   The chassis of this 

product is grounded through the ground-

ing conductor of the power cord. To 

avoid electric shock, plug the power cord 

into a properly wired receptacle before 

making any connections to the product. 

A protective ground connection, by way 

of the grounding conductor in the power 

cord, is essential for safe operation. 

Do 

not defeat the safety purpose of the 

grounding plug.

 The grounding plug 

has two blades and a third grounding 

prong. The third prong is provided for 

your safety. When the provided plug 

does not fit your outlet, consult an elec-

trician for replacement of the obsolete 

outlet.

Danger from Loss of Ground.

   

If the protective ground connection is 

lost, all accessible conductive parts, 

including knobs and controls that may 

appear to be insulated, can render an 

electric shock.

Proper Power Cord.

   Use only 

the power cord and connector speci-

fied for the product and your operating 

locale. Use only a cord that is in good 

condition. 

Protect the power cord

 from 

being walked on or pinched, particularly 

at the plug, convenience receptacle, and 

the point where the cord exits from the 

apparatus.

Phantom Power.

   To prevent 

hazard or damage, ensure that only 

microphone cables and microphones 

designed to IEC-268-15A are connected.

Proper Fuse.

   The user accessible 

fuse is a part of the IEC AC inlet connec-

tor. The fuseholder accepts 5 x 20 mm 

diameter fuses. For 117 VAC opera-

tion, the correct value is 0.25 A, 250 

VAC, standard. For 230 VAC operation, 

the correct value is 0.125A, 250 VAC, 

standard.

Operating Location.

   

Do not 

operate this equipment under any of 

the following conditions:

 explosive 

atmospheres, in wet locations, in inclem-

ent weather, improper or unknown AC 

mains voltage, or if improperly fused. Do 

not install near any heat source such as 

radiators, heat registers, stoves, or other 

apparatus (including amplifiers) that pro-

duce heat. Unplug this apparatus during 

lightning storms or when unused for long 

periods of time.

Stay Out of the Box.

   To avoid 

personal injury (or worse), do not remove 

the product covers or panels. Do not 

operate the product without the covers 

and panels properly installed. Only use 

accessories specified by the manufac-

turer. Clean only with a dry cloth.

User Serviceable Parts.

   There 

are no user serviceable parts inside 

the 528E. In case of failure, customers 

inside the U.S. should refer all servic-

ing to the factory. Customers outside 

the U.S. should contact their distributor. 

Distributor contact information is avail-

able online at www.symetrixaudio.com. 

Servicing is required when the 528E 

has been damaged in any way, such 

as when a 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.
