THERMAL PROTECTION:
The PRO5000 is equipped with a unique protection system
that continually monitors the temperature of the output
devices and takes corrective action to prevent damage to
the amplifier as a result of overheating. Under most con-
ditions, the PRO5OOO’s cooling system can dissipate the
heat required to maintain safe operating temperatures, and
the unit will play continuously. If the amplifier is driven at
high volumes into speakers with an impedance of less than
4 ohms, and/or there is inadequate ventilation, the heatsink
could heat to a level that would cause the protection
circuitry to shut the unit off for a short time (normally less
than 1 minute), to prevent damage. The PRO5000 will
return to normal operation, and if the overheating condition
is still present the cycle will repeat. In this case, check the
surroundings of the amplifier to ensure sufficient air flow
into and out of the vents. Otherwise, check the load im-
pedance connected to the outputs to see if it is far below 4
ohms.
FUSES:
The PRO5000 is supplied with an internal
15 ampere Slo-
Blo AC line fuse. For continued protection, replace this
fuse only with the same type and rating. The fuse is located
on the inside wall near the power switch.
The four power supply fuses on the printed circuit board are
there to protect the output devices if excessive current is
drawn (e.g. a short circuit across the output terminals).
Replace only with
10 ampere 3AG type fuses
