Your Synergy Series amplifier will need minimal
maintenance. No internal adjustments need to be
made to the unit to maintain optimum performance.
To provide years of unhindered operation we
suggest a maintenance inspection be carried out on
a regular basis, say every 12 months or so.
Due to the openness of the air path through your
Synergy Series amplifier, very little dust should settle
within the amplifier. The unit has been designed so
that any dust and/or foreign particles that do settle
within the amplifier will not unduly hinder the cooling
of the amplifier.
The grille in front of the fans will act to limit the
amount of dust and lint entering the amplifier. You will
find in time that there will be a build up of dust and lint
on the grille which may start to hinder the airflow
through the amplifier. You should periodically
remove the dust and keep the grille clean. Removal
of dust from the rear grille will also aid cooling.
Over time, dust may build up on the leading edge of
the fan blades and reduce their cooling efficiency.
The time taken for this to happen will depend on the
environment and the amount of use.
Fans
The fan blades are accessible once the lids
are removed and can be easily cleaned. You
need only hold the fan rotor still and wipe the
dust off the blades. Many users
the fan and use
compressed air to blow the dust off the fan blades. It
is important to note that the fan blades must be held
still whilst blowing air over the blades otherwise you
may burn out the bearings in the fan.
Along with rear panel mains fuse, there are four (4)
rail fuses provided internally in the unit. These rail
fuses are in series with the positive and negative
output supply to each amplifier channel and provide
overall protection for the output stage. If the amplifier
is subjected to heavy use such as short circuits, 2
ohm or bridged 4 ohm loads, these fuses will
eventually fatigue and may require replacing to
ensure they do not fail at an inconvenient time.
NOTE
Make sure the unit is
and is
unplugged from the mains. Give the
main filter capacitors time to discharge
before removing lids and inspecting the
fuses.
You should replace the fuse if the element is
. Only ever replace with the
same type fuse and current rating.
When checking for a failed fuse, do not rely on visual
inspection alone. You should use an ohm meter to
check continuity.
