“James do you have an Amplifier that can play both external and internal sound simultaneously?
This was what my reader asked while I was driving to Banting.
I asked him why do you want an Amp that could play both sounds at the same time.
James, my Sifu said one Amp for all 3 floors is the best set-up. My Sifu uses this set up for all the Swiftlet farms he built for people. Currently I am using his system which the external sound is on the left channel and internal sound on the right channel. I want to get an additional Amp for standby in case something goes wrong.
Oh I see…. So with this type of sound system set-up how many nests you have in your Bh?
Not a lot..James , 8 nests…but I am quite happy.
So 8 nests in 2…3..or ..4..months?
No James, 8 nests in 1 and the half years. But my Sifu said patience is gold. He asked me to wait 5 years. After that if there is no improvement then he would renovation it.”
What a nice, humble and down to earth person, Mr.H of Perlis in very naive. He didn’t know that the 2 channels sound from the SD card or USB is all about cost saving and has got nothing to do with attracting birds. 1 Amps for all 3 floors is to save the use of Amps so that his Sifu don’t have to fork out more money..
I have met many Bh’s owners who know very little above sound system of Bh. Most would think that as long there is sound coming out from tweeters birds would be attracted to it and they would fly into their bhs and stay. It definitely takes more than that.
It is not surprised that many Bh’s owners can’t differentiate between external and internal sound. Some use external sound for internal and via versa. It is not that you can’t use them in such way but the tempos of both sounds are different. Though you may still see lots of birds but the nests building process would be slow. We want nests not birds. No point of having hundred of Birds coming to your farm to play every day but don’t build nests.
The disadvantages of having 1 Amp for all floors:
1) Overloading (shorten the life span of the Amp)
2) If the Amp malfunction the whole Bh is out of sound (if every single floor has an individual Amp then one of them malfunction the Bh still have sound and you don’t have to worry birds fly away)
3) Harder to identify the speaker wires when repairing as all wires are run thru a single connection.
4) Amp that is overload would produce poor quality sound.
5) May cause short-circuit
6) Prolong use would reduce the quality of sound.
I explained to Mr.H about the pros and cons. He was surprised to hear my explanations and told me, “James no one had ever told me about this “.
To my surprise he asked me, “James should I tell my Sifu about it”.
My God! I told him it is up to you…lah. He wondered why his Sifu didn’t tell him about the disadvantages of using 1 Amp for all floors.
If I were him I won’t ask at all. Mr.H is a nice and humble person that is why his Sifu didn’t tell him the disadvantages of using 1 amp for all floors, perhaps his Sifu may not knew it himself.
Good Swiftlet farming All!
