High Quality Audio Design VSX-1016TXV - Direct Energy Power Engine - High Quality D/A Converter - Direct Construction

Power Output Design Comparison Pioneer Denon Yamaha Design Concept Direct energy * Common circuit High current amp* Low Impedance Yes No No Compact design (Power train) Linear temperature Compensation Yes** No(Yes) No Design *High Current Amp: Yamaha claims its their advantage but this method is quite common and most of all HiFi Receiver does this! Actually they are following our “Direct Energy Concept” which we have been using for nearly 10 years! **Pioneer’s Linear temperature Compensation Design is the most advanced version for discrete power amplifier design for minimized the variation of idle current which causes deterioration of the sound. (Denon uses same power device as Pioneer,but Denon doesn’t take care temperature compensation of whole power amplifier desigen) Yes No No

Direct Energy Concept Concept1 ・ Suppress energy loss by minimized impedance design for the last stage power loop circuitry. Thick Connecting Cables Low Impedance Electrolytic Capacitor Ultra Thick Jumper Wiring Large Speaker Terminals Screw Terminal type capacitor Low Saturation Power Device Ultra Thick Connecting Cables Last Stage Power- Loop Power supply Line (-) Power supply Line (+)

Concept2 ・ minimized area for last stage power loop ＝＞ Eliminate radiation influences for sound quality Image for minimized end stage power loop design Last Stage Power- Loop End Stage Power- Loop These current loops radiate interference to the other circuits, and receive the interference from other circuit also, like a Loop Antenna ! Power supply Line (+) Power supply Line (-)

（２） minimizing area for end stage power loop -Pioneer original small power amplifier block = ‘Power Train Construction’ (Concentrating all channel power amplifiers for minimizing the loop) - Eliminate interferences from or to the other circuit by the specially designed heatsink with its shielding effect - Design the best possible construction for minimizing the size of the loop for the power supply and speaker output lines. - Small loop circuitry board Design

Competitor model(YAMAHA RX-V2500) ’05 NEW MODEL(Pioneer VSX-AX4AVi,AX2AV) スピーカ駆動電流により出力素 子のチップ温度が変動、その補 償の無い回路では、バイアス回 路の動作点がずれてしまう。 ADE-MOSFET と同様にバイア ス回路の温度補償を出力素子と 同一チップ化し、チップの温度 変化によるバイアス点変動を極 小化 している。 Speaker drive current cause temperature rise of output element, and drift of the bias circuit’s operation point. The temperature compensating block of the bias circuit is made on output element chip same as ADE-MOSFET, that’s why it can minimized the operation point drift of the bias circuit by the chip temperature variation.
