Constant-current modulation [is] a system of amplitude modulation in which the output circuits of the signal amplifier and carrier-wave generator or amplifier are directly and conductively coupled by a common inductor. The inductor has an ideally infinite impedance to the signal frequencies and therefore maintains the common plate-supply current of the two devices constant. The signal-frequency voltage thus appearing across the common inductor also modulates the plate supply to the carrier generator or amplifier, with corresponding modulation of the carrier output.  5, record 4, English, - constant%2Dcurrent%20modulation

We have to consider what type of gain device is suitable for this application. Actually the choice is simple : Bipolar devices have too low an input impedance to be useable, and tubes have too little gain to be used in a single stage power amplifier. The only usable device is the power Mosfet, which is a transconductance device like the tube, and has a high input impedance, but operates with enough gain at high enough currents to be driven directly by line-level signal.  3, record 6, English, - single%20stage%20power%20amplifier

[L'impédance nominale] est exprimée en ohms, elle indique à quelle «fréquence» une enceinte va fonctionner de façon optimale par rapport à l'ampli. (Par exemple : avec une enceinte qui fonctionne à 8 ohms, et un ampli qui développe 4 ohms, il y aura du son, mais les enceintes ne donneront pas le meilleur d'elles-mêmes (baisse de la qualité et baisse du rendement en décibels)).  1, record 7, French, - imp%C3%A9dance%20nominale
