Foryour safety!
To prevent electricalshock
or fire,do not expose
electronic
products
to rainor moisture,anddo
not remove
covers
(or
back).
lf anything fails,
leave
therepairto a
qualified
technician.

Check
thatthepower amplifier
ismarkedwith
thecorrectmains
voltage.
Placing the amplifier
Thebest
position
for TPA 3036A is
free
on
ashelf
with sufficient
ventilation/space
to each
sidesandthetop,
see
figure.
lf the
shelf
is
open
onthe back,
the space
to the sides
andthe top
can
be
slightly
reduced.
Never
place
the amplifieron soft surface that
canimpedeventilationor in front of or above
aradiator.
lf placing unitsontop of eachotherthe
power
amplifiermust
alwaysbe
positioned
atthetop.
lmportant!:Never
place
any
other
equipment
onthetop of thisamplifier,asthis maycause
damage
to the otherequipment.
Inrack, makesurethatsufficient
ventilation
isavailable,
for instance
a
fan.

Protection
circuits
Electronic
circuits
will
protect
the
power
amplifieragainst:
- Overload
and
short-circuiting
of the
speaker
terminals.
- Flashback frominductive
