This morning while on the computer, received a call from a blog reader from Segamat, Johore।"Harry, need your kind advise. My tweeters are down and worse they are giving out a kind of sqeeky sound. What do you think is the reason?"I check a bit more about his BH background and he poured out his stress. Ai ya so many thing to do and need to learn more from sifu. I told him that he is lucky to हवे Gladiator around. He is so generous with informations and never turn down any call. "Ya ya ya, I know that that is why I alway call you".He started operating his two floors BH about one month ago and everything was fined except during his recent trip he observed that the birds seem to migrate to the lower floor. All of them vacated the upper floor.
He suspected that the sound on the upper floor causes them to move down। He indicated that the sound now seem to be sqeeky and might have chased the birds away।He uses the ordinary cheap tweeters and he could not remember the type of amplifiers and the player he is using.Hmm..... I need to crack my head to figure out what are the possible causes of his sqeeky sound.1) Poor signal generated by his amplifier.I pointed to him that this might be a possible reason. He need to check on the quality of sound immediately after the signal leave the amplifier. He can check this by connecting a tweeter to the amplifier in his data room. Test and see what kind of sound it is giving out. It that is the cause, he need to change the amplifier or perhaps the player. I told him to move from using cd to using memory card.2) Not enought power to the tweeters.If you data room is at the lowest floor, there is a possible chance that the power from the amplifier to those tweeters at the far distance receive too little power. So he should consider to pull a new cable from the amplifier and make a new connection to the terminal end of the sound cable. Cut the present connection in the middle. 3) The tweeters connection to the sound cable were haphazard.If you look very carefully at those sound cables, they come in a pair of wires. The two cables are attached to each other. One of the cable is with a blue color line while the other is plain.Similarly if you order the tweeters from a certified electronic shop, they also will supply your tweeters with cable of a similar nature. One of the cable is with the blue line. Normally they will attach a capacitor to regulate the signal received and to lengthen the tweeter's life. The blue colored cable will normally be attached to this capacitor.When you install the tweeter onto the wooden planks, you must ensure that these cables are installed accordingly. The blue from the tweeters must be connected to the blue line bringing in the signal from the amplifier. You must never install them haphazardly.If you do that, you will have problem with the sound quality. (This advise was given to me by the sifu who own an electronic shop in Klang).4) Chose the right Tweeters and amplifiers.I remember reading an article about a BH owner who suffered almost 3 years with no birds coming in his house to built their nest.After consulting a few sifus, he decided to bite the bullet. He upgraded his sound system using the high end tweeters and amplifiers.After a few short months, his BH seem to show an immidiate turn around. There were more birds and he claimed that his bullet bitting did not damage his teeths. Now he can smile wide.The issue here is about the choice of the tweeters. If you wanted to try, try to visit any shop that sells tweeters and get the sale person to play any birdsound on both the cheap tweeter and the expansive tweeter. Listen to the sound they generated. Make a guess which one is better? Choose those Motorola quality sound tweeters.If you think the cost is too high, how about mix them with a few of the low cost but the majority the good one? But remember if they break down, the cheaper one, it will still chase those birds away.Too bad if the above advises are not useful to you and your BH. Who knows, you might be facing the same problem soon.Just keep the above informations in mind and once you face similar problems, start using the above informations.
