RE: Questions about balanced and unbalanced interconnects

My idea of a fully balanced stereo amplifier is one containing four discrete and separate amplifiers. In other words, each speaker would be powered by two separate amplifiers -- one being fed from Pin 2 of the XLR and the other from Pin 3. The output terminals to each speaker would both be hot with audio signals of opposite phase. In this configuration, if an RCA-to-XLR adapter is used, the amplifier being fed from Pin 3 will have no signal because Pin 3 is grounded in the RCA-to-XLR adapter. Consequently, each speaker can receive only one-fourth of the amplifier's rated power and voltage gain will be cut in half.

Best regards,
John Elison
