Abstract

PURPOSE:To prevent right and left stereophonic signals for stereophonic amplifiers from deteriorating in separation by improving circuit characteristics by reducing output impedance as to a reference voltage generating circuit adequate to generate a bias at a circuit connection point between audio amplifiers. CONSTITUTION:Since transistor TR Q12, Q13 are of common emitter single-ended push-pull constitution, output impedance viewed from output terminal VR is equivalent to that of an emitter follower circuit. Namely, it depends upon base resistances R11 and R13 and current amplification factor hFE of TRs and is extremely small. Thus, circuit characteristics are made excellent, and right and left stereophonic signals for stereophonic amplifiers are never caused to deteriorate in separation.
