| 41. | The audio power amplifier and speaker are quality units that provide solid bass down to 40 Hz.
|
| 42. | The system commonly uses an analogue power amplifier matched to the low impedance of the transmission loop.
|
| 43. | This prevents amplified spontaneous emission and is important for a good beam quality and high power amplifiers.
|
| 44. | This family of designs remains the dominant high power amplifier topology to this day for music application.
|
| 45. | Another important consideration in design of RF power amplifiers is the memory effect or amplifier nonlinear dynamics.
|
| 46. | The number of power amplifiers used in a sound reinforcement setting depends on the size of the venue.
|
| 47. | Power amplifier distortion may damage speakers.
|
| 48. | Electrical servomechanisms require a power amplifier.
|
| 49. | This is a measure of how well a power amplifier controls the undesired motion of a loudspeaker driver.
|
| 50. | II 50-watt power amplifier.
