How many Amps should you use in farm? That is a tricky question. That would depend on the size, the number of floor, the number of tweeters, the type of tweeters, and the watt of the Amp and so on.
Most of the time if not all I would say 95 % of Swiftlet farms are only using 2 Amps, some only using 1 Amp.
Commonly for those that are using 2 Amps, 1 for External sound and 1 for Internal sound immaterial of how big the farm is. It is common to see few hundred tweeters connected to 1 Amp. To me it is a time bomb waiting to explode, it is a matter of time the Amp will break down due to overload (over heated).
All these boiled down to cost saving. Sometimes it doesn’t make sense, I thought Swiflet farmers are intelligent but somehow I doubted. If they could spend hundred thousand on their farms why can’t they spend additional few hundred ringgit for the Amps.
This often happened where the farms were built by some insincere ……consul……. So that they could make more profit.
Some even claimed that the traditional way of using 1 single Amp for all (1 sound for all – Internal & Internal) is the best. Well there are many thought of schools when it comes to this but I definitely won’t use 1 Amp for all and thru my experiences and researches again and again the results showed 2 sounds or more performed much better than 1 sound.
One of the simple reasons of using more than 1 Amp is, if one of the Amps malfunctioned the farm won’t be out of sound the entire period when you are not visiting. Bear in mind we only visit our farm once or twice per month. Imagine if you relied on 1Amp and it malfunctioned then your farm would have no sound and all your birds would be enticed to other farms that have sound.
Secondly having more than 1 Amp you could juggle with the internal sound which would boost up the birds population. This is one of the secrets of pushing up the population of birds. But make sure you know how to juggle between the old and new internal sound. Any mistake make it would reduce the birds population instead. (Call me if you have doubts).
Thirdly having more Amps the number of tweeters will be spread evenly therefore fewer tweeters for every each Amp reducing the load on each Amp thus the life of the Amp will be longer.
Currently some of the Amp in my farms has been running 24/7 for more than 7 years still running now. Never overload your Amps. Once overloaded the life span will be shorten.
There are many more advantages in using more than 1 Amp in farm. The only disadvantage is the wiring is a bit taxing. In long run you would benefit from it.
Good Farming All!
