These devices typically perform functions such as microwave mixing, power amplification, low noise amplification, and high frequency switching.
Teleoperation and power amplification were said to be the first applications, but after recent technological advances the range of application fields is said to have widened.
It combines signal processing from Dolby Lake and power amplification from Lab.
The power amplification was handled by a pair of EL84 working in push-pull configuration.
He also witnesses his future self being killed by Ando, who now possesses some sort of electricity-based power (later found to be power amplification).
Bi-amplification is done so that a cleaner overall sound reproduction can be obtained, since signals are easier to process before power amplification.
All speakers require power amplification of the low-level signal by an amplifier, including headphones.
An integrated amplifier combines the functions of power amplification with input switching and volume and tone control.
These tubes are usually used for power amplification, especially at audio-frequency.
Passive filtering may also be used in this way before power amplification, but it is an uncommon solution, being less flexible than active filtering.
