Hi,
I have few questions in my mind about audio amplifiers. Here goes...
1. If an amplifier is mentioned 16W, what is the current required by the IC when driving a 4 ohm speaker. Is it 2 Amps??? (sqrt(16 / 4))
2. If the current required is 2 Amps, what is the current rating of the power transformer?
3. A transformer of detail 230 / 12 - 0 - 12, 3 Amp. What is that 3 ampere? Does it belongs to 230v or 12v?
4. If i want to design a 5.1 amplifier (6 channel) with three ICs (TA 8215 @ 15W / channel), what is the total current required? suggest me the transformer and its ratings.
5. Is it possible to design a woofer or speaker box with glass?
