From the amplifier's design requirements, Home amplifiers are often used in a quiet family environment, usually used for music and video playback. Home Hi-Fi amplifier is up-and-down broadcasting musical "soundtracks", the request can broadcast out of the level and detail of the music. So Home Amplifiers require a higher degree of fidelity of sound, and softer, delicate, pleasing voice. Professional power amplifiers often used in sound reinforcement occasions, used to drive a loudspeaker reproducing, demanded its full power, driving ability, output sound brighter, clearer and more aggressively enough. So the sound characteristic of a degree of difference between the two. However, some very senior, professional amplifiers are of greater importance to the broadcasted sound fidelity, when used with a high level of professional audio, broadcast voice is clear, detailed, layering is also good.vSqservice manual download site

From the feature set, professional amplifiers are often combined with mixing console and other equipment before working, so much as a pure final stage power amplifier. Professional amplifier setting is very simple, often only Dianyuan panel power switch and input level adjustment potentiometer (or step-attenuator). However, due to the actual need of the professional power amplifier can often work in two-channel status, or "bridge" becomes monaural amplifier, amplifier is provided with "bridged" switch. Home amplifier, many models are equipped with pre-amplifier's "integrated" amplifier, this function more integrated tube amplifier, often with audio source selection, tone control, multi-channel audio input interface.vSqservice manual download site

Judging from the amplifier status, professional power amplifier amplifier efficiency-oriented, so most of class AB amplifiers. Home amplifiers are class AB amplifier, or "high AB class" amplifier, class a amplifier, by means of the dynamic biasing "Super category" amplifier. Judging from the output power, output power amplifier is often large, single output power up to 1000W. Most household power amplifier-rated output power is 200W.
