Fans
Due to the openness of the air path through your Synergy-2 Series amplifi er,
very little dust should settle within the amplifi er. The unit has been designed
so that any dust and/or foreign particles that do settle within the amplifi er will
not unduly hinder the cooling of the amplifi er.
The grille in front of the fans will act to limit the amount of dust and lint
entering the amplifi er. You will fi nd in time that there will be a build up of
dust and lint on the grille which may start to hinder the airfl ow through the
amplifi er. 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 effi ciency. The time taken for this to happen will depend on the
environment and the amount of use.
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 stall 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.
Fuses
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 nega-
tive output supply to each amplifi er channel and provide overall protection
for the output stage. If the amplifi er is subjected to heavy use such as short
circuits, 1 ohm or bridged 2 ohm loads, these fuses will eventually fatigue and
may require replacing to ensure they do not fail at an inconvenient time.
WARNING: Make sure the unit is off and is unplugged from the mains.
Give the main fi lter capacitors time to discharge before removing lids
and inspecting the fuses.
You should replace the fuse if the element is sagging or discoloured. 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.
Only competent or qualifi ed persons should attempt any service or maintenance of your amplifi er.
Your Synergy-2 Series amplifi er 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.
