Information
An audio power amplifier (or power amp) is an electronic amplifier that reproduces low-power electronic audio signals such as the signal from radio receiver or electric guitar pickup at a level that is strong enough for driving (or powering) loudspeakers or headphones. This includes both amplifiers used in home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers and speaker enclosures.
The PS-400MD is a four-channel system with the features listed below
| Channels: | 4 |
| Power Output @ 2 Ohm | 150×4 W |
| Power Output @ 4 Ohm | 100×4 W |
| Bridged Power Output @ 4 Ohm | 300×2 W |
| THD : | Less Than 0.07% |
| S/N Ratio: | More Than 90 dB |
| Input Voltage: | 0.25 V ~ 6.0 V |
| Frequency Rresponse: | 20~20KHz |
| Filter Mode: | LPF-FULL-HPF |
| Filter Frequency: | 40~400Hz |
| Minimum Load: | 2 Ohm |
An instrument amplifier is an electronic device that converts the often barely audible or purely electronic signal of a musical instrument into a larger electronic signal to feed to a loudspeaker. An instrument amplifier is used with musical instruments such as an electric guitar, an electric bass, electric organ, synthesizers and drum machine to convert the signal from the pickup (with guitars and other string instruments and some keyboards) or other sound source (e.g, a synthesizer’s signal) into an electronic signal that has enough power, due to being routed through a power amplifier, capable of driving one or more loudspeaker that can be heard by the performers and audience.
تقویت کننده صوتی (یا تقویت کننده قدرت) یک تقویت کننده الکترونیکی است که سیگنال های صوتی الکترونیکی کم قدرت را تولید می کند مانند یک سیگنال از گیرنده رادیویی یا بلندگو الکتریکی گیتار در سطح که به اندازه کافی قوی برای رانندگی (یا برق) بلندگو یا هدفون است . این شامل هر دو تقویت کننده استفاده شده در سیستم های صوتی خانگی و تقویت کننده های موسیقی مانند تقویت کننده های گیتار می باشد. این مرحله نهایی الکترونیکی در یک زنجیره پخش معمولی صوتی است تا سیگنال به محدوده بلندگو و بلندگو فرستاده می شود.
