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.
