Will a simple moving-coil loudspeaker operate on DC?
The physics only makes sense to me if it operates on AC; is this the case?
The sound signal varies the current from a DC power supply; the variations are what make sound.
Some cheap systems use a single-sided DC amp with automatic gain control (AGC), which adjusts the power supply voltage to save energy. For loud sounds, they quickly turn up the voltage; in quieter sections, they gradually reduce the voltage. The result is that a good speaker system makes high heels on a hard floor sound like Godzilla. This is corrected by a push-pull amplifier; both the positive and negative sides of the power supply adjust to variations in loudness.
The NAD PP-2 is a great product; for years it has ruled the roost among MM/MC preamps. But our TC-760LC aims to change that. Additional features like an output level control, ability to connect MM and MC turntables simultaneously (selecting between them at the push of a switch), and selectable hi/lo MC input inpedance make the TC-760LC the better value; superior specs make it the better choice as well...
