AB  - To drive a speaker with an amplifier requires a connection cord between the two units. The connection cord carried not only the speaker drive current but also current due to the speaker counter-electromotive force, causing a voltage drop. This fact allows no accurate transmission of output information from the amplifier to the speaker. To eliminate any transmission loss, we developed the technique of remote sensing that provides negative feedback to the amplifier from the speaker input terminal. This technique has brought about satisfactory results. This paper reports the theoretical analysis of the technique and its effects when compared with conventional systems.
