Rangkaian Power Amplifier BTL

Power Amplifier BTL Audio amplifiers operate either in a BTL (bridged) or single-ended ("normal") configuration. In the single-ended setup, the output lead goes to the "hot" or "+" side of the load (speaker or speaker box since we are talking audio) and the "-" or "negative" side of the load is tied to a common ground shared with the amplifier....
