HPA-nxV300 380 watt MOSFET Audio Amplifier Module Introduction to the HPA-nxV300 R2 amplifier module. The nxV300 R2 audio amplifier module is based on the high performance nxV500 R2 module. Unlike the nxV500 which has eight Toshiba output devices this version has four high performance Toshiba MOSFET's in it's output stage. Elliott Sound Products - The Audio Pages (Main Index) Pages Last Updated March 2014 Welcome to ESP, the home of DIY audio articles, projects and shortform kits. Audio is a wonderful hobby, and with DIY there is a huge scope to get the very best performance for a lot less money than otherwise. DIY audio is fun and educational, and by building your own audio equipment, you get to learn electronics as well as build equipment that would cost a great deal more in the shops. ESP is committed to providing high quality projects that are known to work, printed circuit boards (PCBs) for the most popular projects, and to assist you if necessary to complete or debug your project.

The compact subwoofer described here will therefore be a welcome addition for most enthusiasts. With its adjustable filter this subwoofer will also work very well with other small (satellite) speakers.As a rough guide the bass response of loudspeakers tends to improve in proportion to their dimensions. This is not completely true, since there are a few tricks that can be used to get a reasonable bass response from a relatively small enclosure.
DAC Final back to www.audiodesignguide.com DAC Final test June 16 st , 2006 Several years ago I started a 'long-term' project to explore the world of Digital to Analogue Conversion. Right now, after many years and a lot of testing with different technologies (see the projects DAC 1.0 to DAC 4.0 on this website and my paper published on audioXpress magazine may 2001) I imagine to have a broad vision of the sonic performance related to this critical component of the audio chain. Resistor Color Codes & Component Identification Resistor Color Code Bands& Other Component Identification Resistor Color Code Identification While these codes are most often associated with resistors, then can also apply to capacitors and other components. The standard color coding method for resistors uses a different color to represent each number 0 to 9: black, brown, red, orange, yellow, green, blue, purple, grey, white.
