Chip Vol
how can i make amplifier to stop humming speakers? It starts humming when i turn up the vol.?
It's circuit of two chips(530 IC). Having Two Mic points attached to each IC with individual volumes for input. It works fine but when i turns up its volume a humming sound comes in speakers.It does't effect by bass or treble switch. what should i do to stop humming this sound. It's two 530IC's work differently on different volumes.
Hi there,
What you have is a groud loop problems, which is that your apmlifier is trying to equal the ground level of your two Mic points though the microphone cable. What you need to do is run one of your microphone cable trough a device called ground loop elimimator. It comes with two pair of RCA cables on both sides, one side for your amp and the other for the mic. If your mic is quarter inch male jack then you'll nee to get a quarter inch to RCA adapter. If your system is mono(mic), then use the white RCA plug to plug in the mic. I live in Canada, and I got myself one yesterday form the Source by Cicuit city retailer.
Hope this help. Good luck!

Do you have moderate or severe knee instability?
Have you ever injured any of the major ligaments that provide support to your knee? These may include your ACL, MCL, LCL, and PCL.
Are you a high energy professional athlete, or a weekend warrior that is searching for knee stability? Then read on!
When it comes to moderate or severe knee instability, or for those of us that are high-performance athletes looking to help protect our knee, the only knee brace you need is the DonJoy Legend. DonJoy has recently changed the name of the Legend to the "SE 4-point" to illustrate its patented 4-point stability mechanism. This custom-fit knee brace has proven to be superior by other knee brace specialists testing procedures. The DonJoy Legend Knee brace is designed to provide stability for moderate to severe ACL, MCL, PCL, and LCL instabilities. You could be moving again with confidence, with the support that this knee brace provides, if you have injured one or more of these ligaments! How could that benefit your life, for the better maybe?
The DonJoy Legend knee brace (aka the SE 4-point) is a well designed knee brace that has unparalleled strength for athletes in high energy contact sports, such as motocross or football. It is absolutely possible to use this knee brace in more than these sports too! Not only is it a durable knee brace, it has a low profile, water resistant design that contours closely to your leg. This knee brace is built for speed and agility, which is a bonus when you do not want to slow you down. The DonJoy Legend has a unique outer covering that is "chip" resistant. This feature makes the DonJoy Legend knee brace safer for salt and fresh water sporting activities.
Research on the Legend knee brace, in a recent study published by the American Journal of Sports Medicine (1) has documented the efficacy of the DonJoy Legend for people with ACL injuries. Eleven people had a special transducer implanted into their ACL (not recommended for our readers necessarily...) at the time of surgery. The ligament strain was tested both with the knee brace donned and with it taken off. The authors of this study reported that the knee brace significantly decreased anterior shear loads up to 130N. These anterior shear loads are the primary loads that will cause a feeling of instability for people with ACL tears. Not only was anterior shear load decreased, but the internal torque strain of the tibia (twisting moments at the knee) was significantly decreased as well.
As a result, the researchers concluded that the DonJoy Legend knee brace significantly lowers the strain on your ACL, which is useful for those people that have had their knee reconstructed and need stability when they return to sports.
