The GaN400 is a “class-D” stereo power amplifier that utilizes GaNFETs (Gallium Nitride Field-Effect Transistors), an 850-watt RMS regulated power supply, a fully balanced topology and a low global ...

The Emotiva UPA-2 Stereo Amplifier is an incredible solution to turn a $500 AV receiver into a real powerhouse - and for FAR less money than it would cost to buy a comparable quality flagship product.

So I'm finalising a set-up for my new build & I'd really like to get it right this time. I have an amplifier rated at RMS 330 watts (Max 600) x 1 channel at 4Ohms (from Sony) So Am I Better Off ...

Current dumping amplifier schematics always looked strange to me. I am considering building one, just to try one out. Solid tantalum capacitors strike again.

The standard requires using a power-supply of 14.4 volts into a 4-ohm impedance and achieving THD of 1 ... No discussion of car audio amplifiers would be complete without covering amplifier ...

Increased power, improved sound quality, and striking new industrial design are among the highlights of this all-new reference Boston GT amplifier line Boston Acoustics, a longtime leader in premium ...

Texas Instruments introduced a family of four digital-input, closed-loop I2S amplifiers for mid-power stereo audio applications including TVs, soundbars, portable docking stations, Bluetooth ...
