An analog amplifier works in analogous fashion, regulating the output stage devices (transistors) to release power from the amplifier’s power supply to the loudspeakers in a manner that exactly mimics ...

It is the only area in a conventional power amplifier likely to give trouble in EMC emissions testing [3]. Even if the amplifier is built into a solidly grounded metal case, and the mains transformer ...

Good description. :-) Another option I’ve used is to pick a transformer with dual 120/120 vac primaries, and use one as the primary, and the other as a HV secondary.

Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, ...

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

Emotiva didn't pull any punches here. They employed a large 850VA toroidal power transformer to ensure the UPA-7 could deliver all of its rated power and then some. The amplifier modules utilize four ...

The power supply circuit, designed exclusively for the preamplifier, enables a stable power supply unaffected by fluctuations from power demanded by the power amplifier stage. An oversized toroidal ...

Editorial Note About Transformers & Power Limiting: The impedance switch doesn't guarantee 1/2 power as you can see in the variable measurements of the above four receivers we tested. ... Amplifier ...

Figure 1 A simple amplifier circuit suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Advertisement The circuit is versatile; its gain can be varied ...

Researchers at Chalmers University of Technology have developed a new type of amplifier that reduces power consumption by 90% ...

Carver is a famous name in audio equipment although they have been known to use odd names for things. For example, the 1980’s vintage M-400 magnetic field power amplifier that [JohnAudioTech]… ...
