In a new episode of Elektor Engineering Insights, Elektor contributor Roberto Armani demonstrates practical methods for audio ...

The Dynasty ProAudio WSA-5RP-Plus wireless audio amplifier may fit in the palm of your hand, but make no mistake, this Mighty Mouse amp packs quite a punch. The two-piece kit comes with a wireless ...

Amplifiers are specified by multiple characteristics including gain, frequency response or bandwidth, power output, linearity, efficiency, noise, and input/output impedances. In wireless applications, ...

Two-minute review. The Rotel DX-5 is a compact, beautifully constructed and very nicely designed stereo integrated amplifier ...

For years, the THX certification process was nebulous to the end user. What did their standards mean? When we attempted to pry information from them, they weren’t very forthcoming, claiming it to be ...

Hello. I browsed the selling ads around my area and this amp draw my attention. It's in a mint condition the sellers description states that it's little used and fully functional. It's listed for 65 ...

The distortion performance of an amplifier is determined not only by open loop linearity, but also the negative feedback factor applied when the loop is closed. In most practical circumstances ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

Pete (AC7ZL) wrote in to tell us about his latest project: building a flat response microphone and channel amplifier. You may remember his previous project: building a crystal radio from modern junk.

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original. I was designing ...
