– 10 – WHAT ELSE DISTINGUISHES THESE AMPLIFIERS? Constant power into varying impedance. It takes twice as much current to develop a given wattage into 2 Ω as it does into 8 Ω — but only half the voltage. Many amplifiers quote a high output current at 2 Ω but have an unpublished operating time measured in a handful of seconds — before ...

– 15 – FLOATED SOURCE EQUIPMENT Source units with a 2-pin mains power cord have no means to connect the audio output ground to earth ground, so usually the audio output ground is floated from earth ground. However , this does not insure that when installed in a system, the audio output ground will remain floated from earth ground. The input cab ...
