Add 12-2-2010: speaker protection circuit for Protecting actively doing resistance to short-circuit protection USED the first landing on the 6-second delay on the loudspeaker amplifier to attribute plus the amplifier output from the DC or high voltage relays come if left Guarding Your speaker to take information from the amplifier
High power amplifier circuits for output protection . Short circuit, overload and speaker delay protection circuit has two stereo and mono khác PCB.
You can make stereo and mono connection circuit LM324 op-amp ( Low Power Quad Operational Amplifiers ) the supply voltage of the circuit board is controlled by two relays on the integrated loudspeaker lines symmetrical + - 6volt 1.2W transformer provided with on Your Own. Speaker lines passing through 12volt 15 amp relay on the circuit stops the relay line in any trouble.
