Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input sign...
A stereo amplifier is the beating heart of any hi-fi system. While loudspeakers and turntables get most of the attention, the humble stereo amplifier shouldn't be overlooked, as without it, your hi-fi would be sitting idly on your rack. As it's British Hi-Fi Week, we thought we'd ...
I'm the managing editor ofWhat Hi-Fi?and have been testing hi-fi and audio equipment for over a decade, including my fair share of stereo amplifiers. An amplifier is the centerpiece of a system, through which music flows both into and out, so it's crucial to get the best performer an...

The Crest Audio CD3000 is a Class-D amplifier capable of delivering 1500 watts per channel into a 2Ohm load. Amazingly for such a brute, the CD3000 only takes up 2U of rack space, and weighs a mere (for a power amp) 21kg.Here's a good question: just why are power amplifiers so...
But if you need an RMS watt and the device has a peak watt. Don't worry just divide the peak watts with 0.707 then you will get RMS watt. Peak Watts? Peak watt is a commonly used power rating that defines the power used by the amplifier for small internal without affecting output ...
have an impedance of, say, 50 ohms or higher, a headphone amplifier is probably a good idea — we would consider you to be in theneedcamp. If your cans are below 32 ohms, they’ll work fine with virtually any consumer audio device. With that said, you could still be in thewant...
With that in mind, here's what you should know about passive speakers, how they work, and when they're the best solution for your audio needs. What is a passive speaker, exactly? In an audio system, a power amplifier, like theBose Music Amplifier, plays a crucial role. It receives an...
Most output caps are around 2200uF so you can see where this is going... Luckily frequency compensation isn't affecting the open-loop gain of the amplifier at this frequency so much, but even then it's an ugly thing and best avoided. I don't browse often, but if you tag me I'll...
