The diagram above summarizes the interaction of the cutting head response (purple) and the playback EQ (red) which produces the final flat response (green). Note that the cutting head and the phono pickup (cartridge) are velocity transducers and therefore the…
The hifisonix kx2-Amplifier features outstanding distortion and noise performance, coupled to switchable class A, AAB or AB operation. It delivers 15W RMS class A into 8 ohms at less than 20 ppm distortion, and >80 watts RMS into 2 Ohms…
Here’s a 9 minute YouTube video I made on soldering SMD components. I use lead 0.5 mm solder with a melting temperature of c. 180 C and my soldering iron temperature is set to 280 C.
The QA 401 from QuantAsylum (now superseded by a newer, improved QA 402) has emerged as a popular, comprehensive audio test instrument in the DIY audio fraternity and the go to instrument in many cases for commercial production testing in…
There is a misconception that noise pickup is reduced by placing the input RCA connectors (and similarly XLR input connectors in a fully balanced system) on opposite sides of the amplifier rear panel and then running short wires to the…
