Operation Manual

1)

Read these instructions.

2)

Keep these instructions.

3)

Heed all warnings.

4)

Follow all instructions.

5)

Do not use this apparatus near water.

6)

Clean only with a dry cloth.

7)

Do not block any ventilation openings. 
Install in accordance with the manufac-
turer’s instructions.

8)

Do not install near any heat sources such 
as radiators, heat registers, stoves, or 
other apparatus that produce heat.

9)

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 ground-
ing prong. The wide blade or the third 
prong is provided for your safety. If the 
provided plug does not fit into your out-
let, consult an electrician for replacement 
of the obsolete outlet.

10) Protect the power cord from being walked 

on or pinched, particularly at plugs, con-
venience receptacles, and the point where 
they exit from the apparatus.

11) Only use attachments/accessories speci-

fied by the manufacturer.

12) Use only with a cart, stand, 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.

13) Unplug this apparatus during lightning 

storms or when unused for long periods 
of time.

14) 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.

15) To reduce the risk of fire or electric shock, 

do not expose this apparatus to rain or 
moisture.

TO PREVENT ELECTRIC SHOCK DO NOT 
REMOVE TOP OR BOTTOM COVERS. NO 
USER SERVICEABLE PARTS INSIDE. REFER 
SERVICING TO QUALIFIED SERVICE PERSON-
NEL.

IMPORTANT

The MA-5002VZ amplifier requires Class 2 
output wiring.

MAGNETIC FIELD

CAUTION!  Do not locate sensitive high-gain 
equipment such as preamplifiers or tape decks 
directly above or below the unit. Because this 
amplifier has a high power density, it has a 
strong magnetic field which can induce hum 
into unshielded devices that are located nearby. 
The field is strongest just above and below the 
unit.

If an equipment rack is used, we recommend 
locating the amplifier(s) in the bottom of the 
rack and the preamplifier or other sensitive 
equipment at the top.

WATCH FOR THESE SYMBOLS:

The lightning bolt triangle is used to alert the 
user to the risk of electric shock.

The exclamation point triangle is used to alert 
the user to important operating or maintenance 
instructions.
